[EyeStrain Burning]

i collect a lot of informations about pc monitors (i’m very thankful to pc monitors)
so i think BenQ XL2411Z rly good choice for me (flicker free … low blue light..)
but i + need your opinion bro maybe there is some bad things in this monitor …! …
thx again

It certainly could be a good choice for viewing comfort. It is flicker-free as you say and has low blue light settings. It is also very responsive, which would help if you are sensitive to motion blur. Motion blur does cause headaches for some individuals, so can be good to minimise in this way.

There are certainly negatives, as with any monitor. From the perspective of viewing comfort it uses a fairly grainy matte screen surfaces, which some users dislike. It is also set up extremely badly out of the box, with a certain ‘harsh’ quality from the backlight. This is much improved after tweaking, so following the guidance on our review of the similar XL2420Z should be helpful.

ok.
+ if i say a flicker free monitor so its also pwm free?!
cause pwm cause eye strain too right
in the review i see its > “” ‘flicker free’ (PWM free) “”

[PCM2]

‘Flicker-free’ = PWM free.

[EyeStrain Burning]

ok thank you pcm2 :).

[EyeStrain Burning]

should we set brightness 100% to get free flicker on a monitor !!
or a wrong info?
or i can set the brightness as i like on a flicker free monitor?!! 🙁
Thanks for the clarification

[PCM2]

If the monitor is not regulated by PWM (i.e. is flicker-free or uses DC dimming) at all brightness levels then you can set brightness to whatever is comfortable. That is the case with most models I recommend and most marketed as ‘flicker-free’.

Setting brightness to 100% can be used to eliminate flicker on monitors that do use PWM (i.e. are not flicker-free) as a method to regulate brightness. PWM is sometimes used to dim the backlight, so setting it the backlight brightness to 100% will avoid that. But you will end up with either very high brightness, which is not comfortable or good at all for avoiding eyestrain, or significant loss of contrast due to having to alter digital brightness controls (in the graphics driver for example).

ok very good thx

Thanks for such a great and informative website.

I too, want to buy the most eye-health friendly monitor possible. I’d like a 27″ for programming (8+ hrs daily) and some late night gaming (mostly FPS – CS:GO). Am unsure whether I should go for TN (with 144Hz) or IPS. I don’t really care about viewing angles as I sit directly at the the desk and don’t watch movies.

My primary concern is the eye health. I’d like a flicker-free, preferably low blue-light (if that’s not just a marketing term) one. Do you have any recommodations?

[PCM2]

Hi mreq,

If you care about colours, then you do care about ‘viewing angles’. It doesn’t just affect how things are displayed when you’re sitting at a funny angle in relation to your monitor. It affects things from a normal viewing position as well. Refer to this article and indeed any of our recent reviews.

In addition to the recommendations throughout this thread, some of my latest thoughts on the sorts of monitors that would be good for your uses can be found elsewhere on the forums. There is also a decent summary of why I don’t necessarily think going for a 144Hz TN panel is going to be beneficial from the perspective of viewing comfort. If you’re sensitive to motion blur, it goes without saying that it could be more comfortable for gaming. But it sounds as if that’s a secondary use for you really.

And don’t get too bogged down with ‘Low Blue Light’; it is certainly a useful feature to have but goes by many names. Refer to this thread.

[mreq]

Thanks for such a prompt reply. The gaming part is indeed secondary but I’d still like a fast-ish monitor. At the moment I’m using an old Samsung SyncMaster P2450, which can get my eyes sore after some time. Not from motion blur I reckon, rather that it tends to flicker. On the other hand, the display of my Sony Vaio VPCZ is perfectly fine (not sure what panel it uses though, based on nice colors it’s IPS).

What’re your thoughts on BenQ GW2765HT?

EDIT: Also ASUS MX27AQ looks promising.

[PCM2]

The GW2765HT is a very good monitor all-around, indeed it’s featured in the recommendations section. But as above, the 25″ options are worth haivng a careful think about as they represent even better value for money – but if you really do want a larger screen, that’s absolutely understandable. I can’t comment on the MX27AQ having not used it, but from experience with the MX series it is unlikely to be calibrated as well as its Dell counterpart using the same panel, the U2715H. Not that that should matter for your uses. It seems you don’t mind about the tilt-only stand either?

[mreq]

Thanks for replying. Once PayPal stops logging me out for no reason, I’ll buy you a beer, as I can’t use your purchase links 🙂

The U2715H seems a bit problematic (google “U2715h flicker”), so I’d rather go for either the Asus or BenQ (or any other recommendation?).

I don’t mind about the tilt-only stand (have it on my current monitor). The Asus is appealing aesthetically as well. BenQ should be fine as well. As for 25″ monitors, the only higher-def I’ve found is the Dell u2515h, which I’ve found users complaining about (see above) as well. The Benq is 80% price of the Asus, which is also worth mentioning. In some of the reviews, however, the BenQ is being criticised for higher input lag (which might bother me in gaming – cs:go).

Calibration: Do you mean as-in color profiles etc. or a manufactured thing I won’t be able to change?

[PCM2]

I’m well aware of the flickering ‘issues’, but they are actually not isolated to these monitors and can easily be circumvented. They are due to the flaky nature of DisplayPort, which can occur with certain combinations of port controllers on the GPU and monitor. It’s far more widespread than just the Dells, it just happens that the Dell models are very popular and so you hear about these issues on them specifically. Most units and GPUs will not exhibit any issues and of those that do it’s usually when people are trying to use multiple U2515H/U2715Hs via MST Daisy Chaining. For those who do have issues, the frequency or likelihood of this flickering is far lower if you use a good DP cable (the ones supplied aren’t fantastic) and eliminated entirely if you use HDMI instead. The monitor has an HDMI 1.4 port, so it should support the full capabilities. But hey, people seem to be having issues with that as well! 😉

I appreciate you might prefer to avoid those models if it’s difficult for you to return the product – you don’t have the luxury of Amazon where you live, I understand that. The other 25″ model I would strongly consider is the AOC Q2577PWQ, we’ve just reviewed it. I’m not sure about local availability for you, however. This would be a good time to note that the issue I was referring to on most of the ASUS MX models is that the gamma tracking is not ‘to standard’ and can’t be adjusted to conform via the OSD. As you’ll see the same applies to the AOC, and actually it doesn’t really matter for general use and gaming which these sorts of monitors are designed for. So don’t worry about that.

If you do like the design of the MX27AQ, which I entirely understand, and don’t care about the stand adjustability – then yes, it could well be a very good choice. I can’t really recommend it based on lack of experience or solid technical data on its performance, but I reckon it should be pretty solid aside from the possible gamma ‘issue’ mentioned above. But I wouldn’t be put off by the input lag of the BenQ, unless you specifically know you have an issue with input lag. The latency of that model is very typical amongst WQHD models. Too many people simply think it will cause an issue for them when it doesn’t, and even if you get a 60Hz monitor with zero input lag – it’s still a 60Hz monitor. The

[mreq]

Thanks. Only the bigger AOC (q2770Pqu) is available in Czech Republic. I am unsure, which of these I’ll pick.

• BenQ GW2765HT – 10990 CZK
• Dell U2715H – 15797 CZK
• ASUS MX27AQ – 13799 CZK
• AOC q2770Pqu – 10990 CZK

Dell costs more than the others. I’ll probably have to roll a dice as I think I’d be happy with any of these 😉

[PCM2]

That’s the thing, really. You’ll be happy with any of those models I’m quite sure. 🙂

[mreq]

Today I’m ordering the Dell U2715H. Thanks very much for the help!

[derekod]

Hi PCM2,

How would you compare the AOC q2770Pqu to the Dell U2715H?
I have had the experience with the AOCq2770Pqu but ended up sending it back over a year ago due to eye strain.
Is the Dell any better with HD video playback? compared to the AOC which I felt was a little soft.
How do the screens compare?
Which would be better suited for photography purposes?
Would you put them both in the same category?
Also how far can the brightness be turned down on the Dell while maintaining an accurate colour?

I currently use a Dell P1130 CRT monitor which I have calibrated using an i1 Display Pro to 80cdm2 which is comfortable to view at 1280 x1024@85Hz

[PCM2]

Hi derekod,

Sorry to hear you’ve had some issues with the AOC. For accurate colour representation (photography) they are very similar. If you run either monitor at the native 2560 x 1440 resolution, then Full HD content (HD videos) are not influenced in any way by the monitors themselves. This upscaling is handled by the GPU or movie software. So they will both be very similar in that respect. The brightness on the Dell can be turned down to around 34 cd/m2 without losing accuracy or contrast which is significantly lower than the ~70 cd/m2 of the AOC. That could be a significant advantage if you’re particularly sensitive to light or want to dim the monitor as much as possible. It makes more of a difference on a large monitor such as these than much smaller monitors.

Hi, I’m looking for a monitor for Webdisegn (not professional), games (no FPS), Photoshop, work (Internet, Word, many programs, many Rss feeds etc). I need:

– 20″ or maximum 22″ (I have a little desk and the monitor is 60cm from me)
– Full HD 1920×1080 resolution
– Good colours and brightness
– Non-fatiguing for the eyes
– DVI
– Maximum 130€ 😡

Maybe I ask too much but I try 😀

Thank you in advance for the help
