    A short analysis of 21:9 future (like LG 34 UM65/UM95) :

    1. Only 34″ and above have enough height. A 34″ 21:9 is the same height as 27″ 16:9 and so it is the minimum 21:9 size you want :

    http://www.displaywars.com/34-inch-21×9-vs-27-inch-16×9

    2. Prices are going to drop (now they are hyped up) as 1080p is moving out of existence in the next two years.

    3. There is no benefit of 3440 x 1440 resolution vs 2560 x 1080 resolution on a 34″ 21:9. (unless you have 20/10 vision and you sit close to the panel )

    In games the aspect ratio matters so you will get more vision in games with a 2560 x 1080 21:9 compared to 1920 x 1080 16:9 but no extra vision compared to a 3440 x 1440 21:9. Keep that in mind. Only professionals would need a higher resolution but then they would probably chose 4k 3840 x 2160 for considerable more working space. Also in games 3440 x 1440 is too hard on the GPU whereas 2560 x 1080 is a little more than 1920 x 1080 (33% times more demanding).

    4. Signal processing and response time need to get on the same levels of 1080p otherwise it sucks big time.

    5. Panel Uniformity is a huge problem too. (brightness and color temperature across the screen)

    Probably a direct LED implementation should be used in such screens (not edge lit).

    6. Probably a 50″ – 55″ TV 1080p is still more enjoyable for entertainment.
    Although i really wish they were flicker free.

    7. No VA variant exists.

    I agree with some but not all of those points. Some users are quite comfortable with the vertical height of a 23″ monitor (which a 29″ 21:9 is equal to) and find the experience quite immersive. I absolutely agree that more height is nice and 34″ is preferable and less ‘weird’, however.

    I certainly don’t agree that there is ‘no benefit’ to 3440 x 1440 compared to 2560 x 1080 on a 34″ panel. You’re comparing something with the pixel pitch of a 27″ 2560 x 1440 monitor to a 27″ 1920 x 1080 monitor. I don’t think anybody would question the difference if you put it like that, would they? That’s like telling somebody they won’t see a difference upgrading from a 27″ 2560 x 1440 to a UHD model of similar size – it simply isn’t true. You don’t need anything other than fairly average eyesight to benefit from the extra real-estate on the desktop or level of detail in games to appreciate that.

    Definitely agree about signal processing, it would be nice to see it lowered. Not everybody is sensitive enough to be bothered by the sort of signal delay we’re seeing on these monitors, however. And the pixel overdrive seems reasonable enough for a 60Hz monitor to be honest, you certainly wouldn’t see the sort of ‘smearing’ trailing you will see on some VA panels on their respective ‘slowest transitions’.

    Panel uniformity can be an issue (and is an issue) with monitors of all sizes, but the pressures placed on monitors of this size are definitely significant. It would be nice to see that improved, be it with some form of digital uniformity compensation or otherwise.

    And as for VA varients, that’s exactly what the upcoming Samsung S34E790C is. 🙂

    1920 x 1080 on 27″ 81.59 PPI
    2560 x 1080 on 34″ 81.72 PPI
    2560 x 1440 on 27″ 108.79 PPI
    3440 x 1440 on 34″ 109 PPI

    Putting enough distance between your eyes and the screen and the pixel grid ( the single most annoying thing in low PPI screens ) becomes invisible.

    However people with good eyesight will find an improvement in clarity in higher PPI screen even from further away. 20/10 between you and me is still 2 x the vision power of 20/20.

    In that regard here is a fantastic calculator that allows you to determine the benefit you gain regarding the combination of : screen size, distance, vision acuity ( including 20/15 and 20/10 ) and resolution ( 1080p vs 4K )

    http://referencehometheater.com/2013/commentary/4k-calculator/ (scroll down)

    As you can see at 60.96 centimeters ( 2 feet in that calculator ) a 27″ monitor for someone with 20/20 visual acuity, the ideal resolution ( where the eye can’t distinguish anything higher ) is 3758 x 2138 so around 4K.

    But for someone with 20/15 you will need 5011 x 2851 and for someone with 20/10 you will need 7517 x 4277 ( so in the territory of 8k )

    The human limit is 20/8 ( the hawk limit is 20/2 ) and now you see why in Japan they said that there is absolutely no benefit going over 8K in resolution but that 8K is mandatory.

    What do you think, the calculator seems to be well made.

    I like the calculator, yes. A very useful reference I feel. I consider 70cm to be a comfortable distance for a 27″ monitor (and even larger displays) myself, at least it’s practical for my current desk. Using 70cm (2 ft 4 inches inches on the calculator) it suggests that the ideal resolution for a 27″ monitor is 3221 x 1833 assuming 20/20 vision (my vision is better than that, but 20/20 is a nice reference to use). So you would still gain benefit from 27″ UHD over any lower resolution at that screen size – not something I’d need a calculator to confirm for me, although it does, as it’s something I’ve seen first hand.

    Given that, I’m not sure why you said that you don’t see 3840 x 1440 as an advantage over 2560 x 1080 on a 34″ monitor when the pixel pitches are essentially the same as 27″ models with a 2560 x 1440 and 1920 x 1080 resolution, respectively. You’d need to be sitting what is in my opinion unpractical (for computer use) distance from the screen for that not to be a noticeable difference in terms of clarity if you have ‘normal’ eyesight. Say nothing for the difference in useful work area.

    Speaking from my own experience with UHD on a 28″ monitor, I can safely say that the difference between that and a similar sized WQHD monitor was profound. This was the case even from a distance of 1m or so, at least for me. Another advantage of raising pixel density even above the threshold of a supposed ‘perfect’ density for your visual acuity is that the aliasing is far less visible even where AA is not used. This can save on GPU horsepower in theory and perhaps give superior edge sharpness to the usual AA solutions.

    Now time to edit your post 🙂

    4 feet 2 inches = 1.27 meters

    70 cm
    2 feet 3 inches = 68.58 centimeters
    2 feet 4 inches = 71.12 centimeters

    Let’s use the 2 feet 4 inches so 71.12 centimeters.

    The ideal resolution for a 27″ at 71.12 centimeters with 20/20 is 3221 x 1833, for 20/15 is 4295 x 2444, for 20/10 is 6443 x 3666.

    What i mean is there is no advantage of 3840 x 1440 over 2560 x 1080 on a 34″ because in game the aspect ratio is the one that gives you more visibility not the pixel count. Moreover this visible map bonus is considerable and increases the immersion.

    Not an advantage in movies either since 99.99% of them are in 1080p so you get a soft image like stretching a 1280 x 720 on a 1920 x 1080 screen. ( 50% in both cases )

    The only real benefit is the image becomes more clear like in real life. But in order for that to actually happen you will also need a Rec. 2020 color space at least. ( so you have the clarity and the colors ).

    Rec. 2020 color space is possible :

    “On May 22, 2014, Nanosys announced that using a quantum dot enhancement film (QDEF) a current LCD TV was modified so that it could cover 91% of the Rec. 2020 color space. Nanosys engineers believe that with improved LCD color filters it is possible to make a LCD that covers 97% of the Rec. 2020 color space.”

    Next year Samsung is focusing exclusively on Quantum Dot & UHD.
    http://www.flatpanelshd.com/news.php?subaction=showfull&id=1415007603

    The UK maker Nanoco ( the only maker of cadmium free Quantum Dots ) is building now a factory in Korea and will provide Quantum Dots to Samsung possibly even to LG starting next year. ( so 2015 lineup of monitors and TVs )

    http://uk.reuters.com/article/2014/09/24/uk-nanoco-group-quantumdots-idUKKCN0HJ0IX20140924

    This color space new standard is even more profound than 4K because colors you could only see in real life will now be possible on LCD screens.

    http://sportsvideo.org/main/blog/2014/10/live-from-smpte-got-color-next-gen-challenges-of-a-more-accurate-viewing-experience-kick-off-smpte-day-two/

    However minimum 10 bit panels are required.

    I am going to buy a TV and a monitor in 2015 and i am glad I’ve waited for this new color space.
    4K is going to drop in price quite fast and it will replace 1080p as the new standard. However there is a need for proper scaling on operating systems as i find the text to be too small on high PPI screens. Again 2560 x 1080 is better here than 3840 x 1440. More FPS in games another advantage.

    Real estate for professionals they will go with 4K.
    2560, 3440 will be resolutions that won’t be a standard.

    If they could make the pixel grid invisible there would be absolutely no benefit in looking at higher PPI screens except there would be a larger usable area.

    So the question with 4K is : does the fact that you can no longer see the black grid around pixels gives you the impression that the image is clear and crisp ?

    Of course I meant 2 ft 4 inches, yes. Little typo there but it seems you worked out what I meant 😉 .

    So you agree that the image being clearer is a benefit when gaming. That is a massive benefit not to be down-played! The aspect ratio is indeed a key immersion factor – and since most games are HOR+ the only thing dictating the default FOV which is very important. Of course 4K/UHD gives you more useable space, that’s true. But many people are very comfortable with the pixel pitch of 27″ WQHD monitors (without the need for scaling) and having that but simply having more useable space horizontally is a big bonus for them. And that is exactly what 3440 x 1440 provides. Not everyone wants to suffer the scaling woes that are associated with 4K/UHD monitors or want to have to buy a truly massive screen to make use of the resolution without needing to use scaling. You’re looking at a 40″ UHD screen to get the same sort of comfortable but very useable pixel density as these 27″ WQHD or 34″ 3440 x 1440 displays.

    There are of course other unrelated factors to consider when it comes to image quality, I couldn’t agree more with that. I personally can’t wait for real advances towards Rec. 2020. We’ve been stuck in the sRGB rut for most content for far too long. Some really nice links there for extra reading as well, I’m sure people will appreciate that. The Nanoco/TREVISTA news was supposed to be added to our Evolution of LED Backlights article as well but I completely forgot to do that 🙁 . I am personally more looking forward to things moving away from the use of backlights entirely (not something Samsung feels is financially viable for large displays at present) but also feel that there is plenty more that can and should be done to really improve the LCD viewing experience. Enhancing the colour space on displays very broadly so the designers can feel comfortable expanding their own palettes is extremely important.

    P.S. It’s not true that the majority of movies are 16:9 at all. Certainly not ‘99.99%’, that is utter rubbish (like most statistics). Most films are mastered in ‘Ultra Wide’ aspect ratios such as 2.39:1 unless they are TV shows. It’s what most modern cinema screens use and is extremely popular with the big directors. It depends what you watch of course. And you can have those 16:9 films looking as they would on a 27″ monitor if you don’t like the softening. Big black bars at the sides (like in this article). Not ideal though, I won’t pretend it is.

    Samsung is not going for OLED. Not even in 3-4 years. Never.

    OLED in it’s current incarnation with organic materials will never last enough. It’s a huge marketing lie and Samsung doesn’t want to be part of it.

    LED LCD with proper local dimming can show excellent results. Also take into account that LEDs will have a huge drop in prices once they start being mass produced to replace normal light bulbs, street lightning, public illumination, museums, galleries etc. and that means very cheap local dimming TVs / monitors with 100, 200, 300, 400, 500+ local dimming zones.

    Take a look at this discussion between a user and a industry insider :

    Insider sh4 :

    “Forget OLED. Due to fast degradation, 2.5x power consumption at the same brightness vs LCD, imprints, it’s another dead tech after plasma unless its production cost will be dirty cheap. It will never be your computer screen though.

    Counter comment from tomas :

    “@s4h
    you are way off with your comments… power consumption is less than LCD, if by degrade you mean the blue light half life span ..then that was resolved by LG using white and Samsung by using a larger blue, …overall OLED uses the same manufacturing process (in fact it has less steps than LCD)….once yields have increased the price will drop…it is already happening if you compare the high prices last year with the latest OLEDs launched… this is not dead tech ….once they hit the right prices and they will …the market will adopt them as it is Superior to LCD…in the long term for TV manufactures it will be cheaper ( hence bigger profit) to make OLED TVs.”

    Reply from sh4 (insider) :

    @Thomas
    Don’t lose your common sense, for example in Samsung case larger blue does not fix the problem, it just align still relatively short degradation lifetime for all three colors.
    Proof of my words is in non-existence of hi-end OLED monitors. Nothing was fixed, the life span was just extended from completely unacceptable still being not even close to the one of LED backlit LCDs. The numbers so far were in the range of 4000 hours for OLED. Even if this will be 10000 that is still 3 times short of LED LCD

    james also wanted to say something about sh4 comment :

    ‘I agree with s4h if OLED is not capable of providing adequate screen life span in comparison to existing technology the price will be irrelevant as the OLED market will suffer as a consequence of bad consumer reviews. The market always determines the adoption of technology not the manufacturers, the only proviso would be if commercial incentive was behind superseding a well established LED market to future proof OLED investment for the movie and entertainment industry especially with the potential of 4K video streaming.”

    —————–

    All in all from the second you use it the OLED starts to deteriorate and it will need multiple calibrations during its short lifespan. LG is using people for experimental testing with devices like TVs that are supposed to work, let’s not say 25-30 years like old quality CRT, but at least 10-15 years, and in reality they last 4000+ hours.

    Probably the best LEDs last 50000 hours and cheeper LEDs around 30000

    In case of the 50 000 that would mean :
    12 hours per day 11.4 years
    8 hours per day 17.1 years

    When LEDs in a TV / monitor become too dark since they don’t die but actually slowly lose brightness over time you can simply replace them and fix your TV / monitor.

    With OLED you throw your piece of expensive art directly into the trashcan.

    Have you seen the Vizio P series from USA : http://televisions.reviewed.com/content/vizio-p652ui-b2-p-series-4k-led-tv-review

    50 inch model priced at $ 999 4K screen direct led with VA panel and full array local dimming with 64 zones.
    Definitely better than LG 34″ 21:9 3440 x 1440 for immersive entertainment (moderator comment: matter of opinion – the FOV in games is more important to some people and so is decent motion performance. And 50 inches is verging on ridiculous for a computer monitor. Immersive, perhaps, but also impractical for most – even 40″ is pushing the boundaries. The pixel pitch on that would be similar to a 25″ Full HD screen as well, definitely not for everyone and hardly the sort of UHD experience many computer users strive for).

    http://www.displaywars.com/50-inch-16×9-vs-34-inch-21×9

    Fortunately Vizio might come to Europe too next year because of this :

    http://en.wikipedia.org/wiki/Transatlantic_Free_Trade_Area
    http://en.wikipedia.org/wiki/Transatlantic_Trade_and_Investment_Partnership

    “The TTIP free trade agreement could be finalised by the end of 2014.” ( meaning free trade between US & Europe )

    A separate proposal for free trade between north American continent [US, Canada, Mexico] and Europe is also under way.

    However there are also negative reactions to this corporate mega power trade deal : https://stop-ttip.org/

    I don’t share your pessemism regarding OLED at all. And know nothing about the credentials of this so-called ‘industry insider’. And rather than being an armchair theorist, you’re speaking to somebody with very relevant industry contacts who follows this sort of technology extremely closely. Being privvy to some information I can’t share here (or here), you misjudge Samsung’s intentions. They have not abandoned the OLED (or more correctly, backlightless) path – far from it. They have temporarily cut off production of their larger panels. Their strategy for RGB OLEDs is not economically viable at present for some of the reasons covered in our article and that discussion you posted.

    But that isn’t the end of the story. Great strides are being made to improve lifetime of the organic compounds of all colours. A lot of what goes on behind the scenes isn’t public knowledge – and since it involves a highly competitive industry, for good reason. And of course LG are still very much in the game – they chose to use an entirely different design for their OLED which allows each pixel to become an independently controllable light source. Much better than even zonal dimming control on a backlight (which is a nice development in itself and I agree is becoming increasingly viable). But this still relies on a colour filter, just like an LCD matrix. Zonal control has actually been experimented with on higher end monitor prototypes and it simply doesn’t work properly unless the screen is very large. I do feel this technology has a future in monitors and will be improved for smaller screen designs.

    It isn’t just about contrast and uniformity though, important though such factors are. It would be nice to do away with the response time limitations of the technology as well. This is particularly true when considering your much-loved VA panels. No matter how beautiful you make the image, once it comes to motion performance they always fall short. There are always problematic transitions which bug the heck out of some users. Given your enthusiasm towards Quantum Dots, which I certainly share, I’m surprised you didn’t consider the obvious alternative to both OLED and LCD that they provide. It is of course possible to use those brilliant and stable little dots as both the light source and ‘colour filter’ (i.e. pixels). This is definitely something that’s being kept under fairly tight wraps, but it would be naive to assume that using films of these things as a backlight is the end of the story.

    Armchair theorist or not there are many versions and ways to build a cool new type of panel.

    Samsung also invested in this company : http://www.oled-info.com/israeli-company-develops-bio-organic-led-displays-compete-oleds ( bio-organic LED displays to compete with OLEDs )

    OLED also needs some black frame insertion or some other methods to solve motion blur issues.

    “Despite boasting insanely fast response time, the current generation of OLED televisions are driven by sample-and-hold method, so their motion characteristics resemble LCDs instead of impulse-type displays such as CRTs and plasmas. ”

    Alternative to both OLED and LCD ? Are you referring to QLED?

    As far as i see they also have blue problem and are even more expensive than OLED.

    “However, blue quantum dots require highly precise timing control during the reaction, because blue quantum dots are just slightly above the minimum size. Since sunlight contains roughly equal luminosities of red, green and blue, a display needs to produce approximately equal luminosities of blue, red and green. The human eye requires blue to be about 5 times more luminous than green, requiring 5x more power”

    I doubt that they won’t degrade. It could be marketing you know. They always say how they will make them last 10 times more but there is no device that was tested that long.

    What we are going to see next year will be : http://www.nanocotechnologies.com/what-we-do/applications/display

    A question : if they use Quantum Dot film will they still need to use back-lights such as GB-LED ( instead of conventional blue diode coated in yellow phosphor GB-LED combine blue and green diodes with a red phosphor ) in order to reach Rec.2020 ?

    I wasn’t calling you an armchair theorist, incidentally. I value your opinion and the excellent discussions you bring to this forum far too much for that. This very thread is testament to that – some really fantastic discussion going on here and some really interesting concepts being explored. I couldn’t agree more that there are lots of interesting ways to build panels and backlight systems – and the more options the merrier as far as I’m concerned.

    When it comes to OLED, though, it’s something I follow extremely closely. I stripped some of your links away in the previous post as we have our own ever-expanding resource on the topic. When that article was first conceived 4-5 years ago the website you mentioned (OLED-info) was instrumental as a source of reference. And indeed a reference of references. Since then I have built up relationships with many contacts – manufacturers, their PR teams, engineers and more. I have also been fortunate enough to discuss some emerging technologies (including new fabrication processes for OLED and even new organic materials yet to be seen commercially). A lot of what I now know can’t be discussed. It isn’t in the public domain and it isn’t necessarily all something to look forward to in the immediate future either. It does allow me to say with certainty that dismissing OLED as a useless/dead technology for computer displays is foolish. And Samsung most certainly haven’t abandoned the technology (they’ve invested far too much time and money for that). Although they may be considering some changes of direction whilst things are… How shall we say… Ironed out. In the somewhat shorter term they might just be a bit more interested in LG’s WRGB-OLED designs that they let on.

    And yes, the responsiveness of OLED is of course limited by the refresh rate and frame rate unless the pixels use strobe illumination (impulse) rather than sample and hold. It is certainly good having a highly colour-capable display that can provide a nice 120Hz+ output without overdrive artifacts or trailing from slow pixel responses, though. That is all covered in another of our articles. 😉

    For Quantum Dots as self-illuminated pixels I was referring to QLED, yes. They are not organic so are much more stable than OLED materials. The technology is so tightly under wraps and most of what is known (including what I know) on that is shrouded by a fog of marketing – you’re right about that. There are definitely hurdles to overcome with all of these potential alternatives to LCD, but I’m optimistic it’s a question of when and not if those hurdles can be overcome.

    Using Quantum Dots as a backlight is covered in this article. It includes Nanoco’s latest CFQD developments as well. These replace the phosphors on the backlight entirely and give potentially ‘extreme’ levels of green and red energy once excited. The blue component comes from the usual InGaN blue diode (or others such as ZnO@TiO2 and other bizarre compounds) and it’s that which both excites the Quantum Dot film and provides the blue energy as required. This is exactly due to the limitations with blue Quantum Dots that you’ve already touched upon. When I spoke to Jeff Yurek of Nanosys he was quite confident that Rec. 2020 would be achievable using this technology in the future, with 97% coverage a fair estimate in the near-term. His blog (dot-color) is extremely interesting, you’ve probably come across it already. You can see he is a big proponent of the technology and some of the sorts of concepts we’re discussing here.

    I enjoy talking to you PCM2, you have a great character and that is the most important thing in a person.

    I definitely support Q LED or Quantum Dot Displays, as i always enjoyed things that last over time – things well made not just with profit in mind and short product cycles.

    http://www.nanosysinc.com/dot-color/2014/9/16/uhd-actually-means-better-pixels-not-just-more-pixels

    For 2015 i speculate we will see :

    1. High dynamic range with dynamic back-lighting ( the screen divided into many rows and columns of cells, with each cell composed of groups of RGB LED clusters. By independently controlling the light output of each cell (based on the image content), dynamic backlighting improves the image contrast ratio. As backlight and driver costs come down, the next-generation high-end TVs could apply the dynamic control to each RGB LED cluster within a cell for an even finer-grain control of the backlighting. All that the system has to do is monitor the video content and feed a control signal back to the backlight controller to dynamically adjust the LED brightness in each cell. )

    http://electronicdesign.com/boards/dynamic-backlighting-boosts-contrast-ratio-trims-power-small-lcds

    But will this cause more PWM ?! I always wanted a PWM free TV.

    2. Wide color gamut Rec.2020. But will this be usable with normal LED + Quantum Dot film or will it need GB-LED + Quantum Dot film to cover Rec. 2020 color space ?

    3. True 120 Hz / 100 Hz panel (not done internally) with true 10 bit for both Full HD & 4K.

    For 2016 : Quantum Dot Displays should be introduced to replace LED and OLED altogether in all panels.

    Just like 21:9 was surprising a new format may be surprising too in a good or bad way : the 1:1 format.

    Eizo EV2730Q comes with a 26.5″ panel with 1920 x 1920 resolution ( 102.46 PPI or 0.2479mm )

    http://www.eizoglobal.com/products/flexscan/ev2730q/index.html#tab01

    The important question is what is the best display format considering our own human visual system ?

    Is it 21:9, 16:9, 16:10, 4:3, 5:4 or 1:1 ?

    Humans have an almost 180-degree forward-facing horizontal field of view. The vertical range of the field of view in humans is typically around 135 degrees.

    Binocular vision, which is important for depth perception, covers only 114 degrees (horizontally) of the field of vision in humans, the remaining peripheral 60–70 degrees have no binocular vision (because only one eye can see those parts of the field of view).

    ***

    A very good read (read the comments too) : http://www.sundoginteractive.com/sunblog/posts/why-16-9

    So 4:3 is the best choice for what the eyes can actually focus on. But wider takes into account peripheral field of view and is more pleasant.

    What is your opinion over this matter ?

    I’ve known about the 1:1 LG panels for a while and actually saw a very similar Samsung ‘square monitor’ prototype a few years back. I think that it’s nice to have different options there to suit different uses and preferences, but for me personally I would find both the resolution and lack of physical width too restrictive. These 1:1 panels were initially designed with a very specific use in mind – to be put together in a way that would allow for great flexibility in a digital signage situation.

    For my own uses I find the use of peripheral vision very important, and of course your field of view at any one time is only one small consideration. The eye is full of muscles to allow it to move – and indeed it does so constantly when tracking movement on the screen. Whether or not you can see all of the content on a screen at once isn’t really the be all and end all.

    Let’s consider :
    34″ 21:9 2560×1080 ( 81.72 PPI ) & 32″ 16:9 2560×1440 ( 91.79 PPI )
    http://www.displaywars.com/34-inch-21×9-vs-32-inch-16×9

    For the sake of it lets just ignore PPI since the 32″ can come in 3840×2160 (137.68 PPI ) and the 34″ can come in 3440×1440 ( 109.68 PPI ) or more in the future.

    The 32″ 16:9 has a 4.54% larger area than 34″ 21:9. In other words the 34″ 21:9 has a 4.34% smaller area than 32″ 16:9. (negligible many would say)

    Which one in your opinion generates more satisfaction of the human visual system while looking from the exact same distances ?

    Do you think that the 21:9 trend will replace eventually 16:9 screens in both monitors and televisions ?

    Or is the lack of height a huge detriment in terms of vertical field of view ?

    For me, personally, I prefer the UltraWide model with all else being equal. Not because of the physical size difference (that isn’t all that great, as you demonstrated) but because you gain a greater FOV in most games. I found this FOV difference to make a real difference even on the 29″ models, at 34″ from a similar viewing distance it’s stepped up further.

    I think this one really comes to to personal preference a bit as well. I personally find the 34″ curved UltraWides to be particularly comfortable on a visual level if you sit quite fairly centrally (otherwise the curve is quite odd).
