    “…The reason the X34 is featured as a recommendation, currently, is that I can’t see a compelling reason to pay more for the PG348Q. Some people prefer the brand or aesthetics which is fair enough (and they’re both excellent monitors in my view), but core performance is very similar. I also quite like the ambient lighting feature on the Acer and feel it has more utility than the red projection on the ASUS.”

    Hi you (or a rep from this site) wrote this a year ago and I would like to know if anything has happened in the market to change your mind? I’m interested in the AOC Agon AG352UCG, however I haven’t found a solid release date other than March 2017. I’m running with a Strix1080 card and have some interest in G-sync. I am looking for a curved monitor at 34” and above and higher than 60hz and greater than 1080p resolution. Thunderbolt is desirable but isn’t a must. This site is extremely valuable and I will purchase using links from this site (once there’s a link for the Agon should that become available).

    I was anticipating a bit lower price of 855.00 usd. I’m aware of market value for the reported features and relative high-end Acer/Asus models. I finally got around to reading the reviews in January and tagged this unit to follow for a rig I hope to build in the next couple weeks. The only other models that generated interest to this amateur were the Samsung and Microboard models. The Samsung review as all your reviews, was solid. The Microboard M340CLZ was introduced to the market however I haven’t seen much followup.

    Also I’d like your opinion of two LG models that have out-performed per reviews and user feedback… 34″ or above, curved, 75hz+, ips/va, DP 1.2, higher than 1080p and decent response.



    Hi jakesno,

    I have formed this into a new thread. I notice you originally posted in the ‘Monitors for Console Gaming’ thread, but these models are clearly for PC gaming rather than console gaming. Perhaps it was because that thread has been quite active recently, which I understand. I hope I didn’t scare you away from starting your own thread with my tendency to merge threads, where possible, to keep things together. Anyway, this is a popular topic and the moment and certainly deserves its own place. I’ll keep my reply structured in bullet points to keep things clear and concise:

    – It would be me who posted that as this site doesn’t have any ‘reps’ ;). Wish it did sometimes but no such luxuries! The PG348Q replaced the Acer X34 in the recommendations section for reasons of price and availability but also because it has proven to have more solid quality control. The rate of return of the Acer X34 was particularly high, from the users I was able to monitor (i.e. who bought via the links on our website) and much more so than the PG348Q.

    – The PG348Q is certainly a solid choice and it does have a bit of an edge in responsiveness over the VA models that have now come onto the scene. But the edge is not massive and I think most users would actually prefer the balance of responsiveness, higher contrast, lower chance of troublesome backlight bleed, lack of IPS glow and in some cases superior colour gamut that comes with some of these. Oh and the slightly lower price that is expected doesn’t hurt either. When these models are more established I’d fully expect some to feature in the recommendations section.

    – I do feel that G-SYNC is quite valuable, as a user of an Nvidia GTX 1070. I always like to keep frame rates pretty high regardless of this (ideally 80fps+ really), but it certainly gives you a bit of flexibility and headroom with the settings when you’re not trying to make sure things stick like glue to 100fps to avoid stuttering or tearing. It depends on the games you play and settings you like to use and also your sensitivity to stuttering and tearing. But all else being equal G-SYNC is a really nice feature to have if possible, I’d perhaps only be comfortable being without it if I had a really powerful single card like the upcoming GTX 1080 Ti.

    – I’m not sure exactly when AOC America are planning a release, but in Europe it’s supposed to be around March 22nd and I would expect if they do stick to March in the US it will be the tail end of the month. I think your price estimation is fair and I think that whichever way you look at it, this is going to be an appealing monitor for UltraWide gaming for Nvidia users. Especially given the price.

    – I assume you are referring to the Samsung C34F791? We haven’t actually reviewed that yet (will be very shortly), maybe you were thinking of the ASUS MX34VQ? I was actually rather impressed with the ASUS. It did have a slight edge over the AOC in terms of responsiveness and colour consistency as well. Depending on your perspective, could be worth going for the AOC as an Nvidia user who could benefit from G-SYNC instead, which could be far more valuable.

    – Microboard models aren’t available here in the UK and don’t have an established PR firm or any official channels in which to acquire review samples over here. So they aren’t something I’ll be able to test or provide feedback on myself. Seems to offer decent enough value for money, but again you’d be forgoing G-SYNC with the M340CLZ and from the feedback some users have provided it sounds like the pixel overdrive might not be as well-implemented as on the models I’ve tested so far (ASUS and AOC).

    – The LG 34UC98 and 34UC88 are by all accounts decent monitors and ones I’ve recommended to users who focus primarily on productivity but also fancy a bit of gaming. They are limited to 75Hz only, though, and apparently will skip frames on Nvidia GPUs at that refresh rate so are actually limited to 60Hz. I feel that the higher refresh rate, possibility of G-SYNC and overall contrast just makes the likes of the AOC more appealing for gaming really.

    P.S. Your desire to support the website is much appreciated as well. I’m sure you can see how much time and effort goes into this resource. Sadly not everyone does understand that aspect.


    Thanks for responding,
    Outstanding feedback. I’m glad I tagged the AG352UCG. IMO choices aren’t that difficult with ultrawides at 34″ and above, however should I totally discount user reviews who claim to be overclocking Free-Sync (lotta LG/Nvidia claims) models above 60hz or their native specs with Nvidia cards? Seems I see this mentioned along with 1080’s. They don’t claim to get the full overclock yet some claim better than the unit’s native specs.

    I have also read a review or two of users migrating from 34″ Acer (Amazon review), and Asus brands (not Amazon review(s)) to LG 38UC99-W and not feeling noticeable input lag. I try not to invest/divest too much into user reviews however they are useful.

    I look forward to your Samsung C34F791 review.


    I wouldn’t totally discount them, no. I’ve also seen some suggesting that the newer Nvidia GPU series (Pascal) can run those monitors at 75Hz or so. Then again, few users know how to check for frame skipping. And indeed the benefits of G-SYNC, 100Hz and the stronger contrast of the AOC would still come into play regardless.

    The same applies to the LG 38UC99 in that it lacks those attractive features, but 3840 x 1600 on such a large screen does certainly have its attractions. It’s more diffiuclt to drive at high frame rates, of course, but with an overclocked GTX 1080 you should still be able to achieve a solid 75fps on some titles with a bit of careful tweaking. In addition to being limited to 75Hz, the input lag is moderately high and pixel responsiveness actually quite weak for an IPS panel. This can only be accelerated effectively using the ‘High’ response time setting, which introduces significant overshoot. User sensitivity to input lag, latency, pixel repsonsiveness etc. does vary, but I feel the AOC is still a more attractive prosepect for gaming overall.


    i’m currently using the LG 34UC88, the curve and general picture quality is great and even the black uniformity is surprisingly good for an IPS.
    But this might be the cost for various downsides; the white and grey uniformity is rather mediocre and the response time is on the edge of acceptable.

    I thought the 75hz might increase response time a little, but with an Nvidia 1070 the only result is frame skipping.
    So i borrowed a RX480 and put it in the lower PCIE slot and connected the display port cable to this card.
    The monitor detected the Freesync signal and unlocked the 75hz, even if Freesync itself is disabled in the driver.
    I connected the cable back to my Nvidia and the Freesync mode on the monitor was still active, no more frame skipping at 75hz.
    Seems it uses some kind of firmware lock to restrict the 75hz to Freesync capable cards only.

    Now i’m looking for a proper replacement, the Asus MX34VQ looks very promising (thanks for the review btw!).
    My initial budget was about 600€, but i’m willing to increase if it’s beneficial.
    Key factors are: 75hz+, good response time, IPS/VA, WQHD+
    Those AUO AHVA 144hz panels seems to have some severe quality issues (this panel seems to be exclusively used for all 2560×1440 IPS 100hz+).
    So i guess it is between the Asus MX34VQ (800€) vs. Samsung C34F791 (900€).

    Can you please give me an advice?


    Hi Default and welcome,

    I appreciate your feedback on the LG, it’s in-line with what has been reported by some other users as well. So it seems lock a sort of ‘lock’ for the 75Hz capability that ‘requires’ the monitor to at least think it is communicating with a FreeSync-capable GPU.

    With respect to the ASUS vs. Samsung, I’ve shared some thoughts here – I will of course have more to share once I’ve reviewed the Samsung, which I will be doing shortly. Given that your original budget was €600, I already feel that the ~€800 MX34VQ is pushing things. I do think it’s worth the money if that’s the sort of monitor you’re looking for, but it’s more tricky to say whether the Samsung is worth paying an extra €100 for. That is a closer match between prices than in some other regions, but take a look at the points raised in that other thread I linked to and think whether that is worth the extra to you. Both models have their pros and cons as well, it isn’t the case that the Samsung offers only advantages over the ASUS at all.


    Thanks for your kind reply.
    I’ve checked AUO 144hz IPS panels again and it seems that the Acer XB271HU uses a slightly newer panel revision (M270DAN02.6) with less quality control issues.
    The pcmonitors review of the ViewSonic XG2703-GS (probably a very similar model) looks good as well.
    The C34F791 and MX34VQ is unfortunately not available yet, altough i’m willing to wait for it’s release.

    Between the ViewSonic XG2703 and the Asus MX34VQ which one do you think is more worthy?


    Whilst the ViewSonic XG2703-GS and Acer XB271HU offer better quality control than the likes of the ASUS PG279Q, they’re still weaker than average in that respect. This was highlighted in the ViewSonic review and is something that makes me hesitant putting them up in the ‘recommendations section’. Which is a shame, because they’re nice monitors if you get a good unit.

    But putting this to one side, I really feel the MX34VQ is even more of a ‘special’ gaming monitor. The ViewSonic is more responsive, not least as it has a higher refresh rate and offers more consistent colours. But that’s about where its advantages end really. The stronger contrast of the ASUS is a really nice bonus and the responsiveness remains pleasing. But it’s really the 21:9 aspect ratio and 3440 x 1440 that adds that extra special something to gaming. The curve works nicely as well, which is another aspect users can be unsure about until they actually see it first-hand. It’s quite subtle but sort of draws you in a little more – some users also find it more comfortable when compared to flat screens of the same width. Which I do understand, although my eyes are quite unfussy either way even if I prefer the curve for other reasons

    Once you’ve seen this for yourself, you’ll really not want to go back. I can tell you that going back to my own Dell S2716DG has been difficult after testing these high refresh rate UltraWides. I’m looking forward to my Samsung CF791 sample arriving not just as a reviewer but also a gamer; I personally really enjoy 21:9 gaming. 🙂


    Thanks again for your response.
    The curve feels indeed really immersive, it also seems to diminish the viewing angle issues of both technics (less glow for IPS, less shift for VA.)
    I’m also a bit tired of IPS troubled monitors, VA could be a nice change. The price increase of “only” 100€ for a less troubled monitor with more image area seems plausible, those 144hz IPS panels feels more like 500€ max value.

    I think i will await your Samsung review and then take my final choice (will order from amazon through pcmonitors reflink).

    On a sidenote:
    Have you considered to add some oscilloscope tests for the response time? (Not meant as criticism, the responsiveness sections is nicely done and especially the response time videos are very helpful, showing some real-time usage with good explanation/commentary).
    This is also pretty unique, most sites have either a text or video review and if they did both it mostly feels somehow separated. Here are both parts cleverly and useful connected, really like that approach.
    (Just think this would add the final touch to the responsiveness section.)


    That sounds like a good plan. 🙂

    Yeah, I’ve dabbled with the idea of oscilloscope-based response time measurements. And I can certainly see their merit. But only if they are done in enough detail and a sufficient number of pixel transitions are looked at (I see the ‘detailed measurements’ section of TFT Central as a bare minimum). That would be too time-consuming to do alongside our other subjective testing and the pursuit photography, really, and I sort of like a bit of diversity and doing things in a different way to other sites. I would not rule it out for the future though.


    I like TFT Central, but not enough to create an account (nuff said)

    Where do you see the AOC AG352UCG lining up against these other 21:9 screens you’ve tested?


    That’s covered in my first essay response. The MX34VQ with Samsung panel has a slight edge in responsiveness and colour consistency, nothing massive. But it is G-SYNC that some will really admire.


    Unfortunately the Samsung C34F791 review has been delayed slightly due to the small matter of our main test system failing.

    Edit: Review now up and a comparison here –


    Just an FYI: The AOC Agon AG352UCG is now available for (pre)order from (USA), Price is 899, free shipping for prime. Delivery in 1-2 months which is Amazon code for we got all the details on the item but have few if any actual units to ship thus far.

    Has your preliminary review of the C34f791 progressed far enough to give an updated opinion as to how you feel the screen stacks up to the above named AOC or does it remain unchanged? Everything I’ve seen has me favoring the Samsung a slight edge except for the lack of g-sync. I know I should wait to see what the sh711 holds since I prefer the 32″ 16:9 over the smaller PPI of the 34/35″ 21:9.


    Hi. I’m following this thread because i’m very very challanged about a couple of monitor. The Omen X35 (i prefer it over the agon because of the steeper curve, the aestethics and main important reason it is 5cm short having space problem at the left part of my desktop) and the samsung CF791. Since you reviewed both panels (the Agon shares the same panel with the Omen), what do you think?

    The gpu is not a problem, i want to change my actual 980ti in future and i’m only fanboy of my wallet, so no problem to buy Vega or the 1080ti when the times will come.

    I red a lot about samsung’s problems and faults(dead pixel problem, dust under the screen and other QC issues, input lag noticeable high and so on). I see also that the difference in gamut is not so high once both monitors are calibrated as you told comparing the samsung with the Asus.

    The price is not a real issue between the 2. In italy the cf791 will cost around 1000 Euros.

    I hope you can clarify me better the strong and weak point comparing the 2 models. Does the quantum dot really worth it? Or it is better to go through the more “solid” Omen way?

    Thanks a lot
