    Not that I would recommend the VG240Y with the colour settings issue but if anyone is interested in the overdrive on the UFO test I captured some 960fps footage of it with my phone’s super slow motion mode. I’m no professional so its hand stabilized and not focused perfectly but just more info out there for people looking can’t hurt.



    It seems that lot of people had this issue with the Acer. You can see this on Reddit… it’s very annoying…


    Hello, I’m looking for this new 144hz ips monitor. But I have some doubts that maybe you can resolve.
    1) I have at the moment an old ml239H , advertised as a 5ms(maybe 10-15 with 40 of trace setting) . I see that the AOC 24G2U with the suggested overdrive setting is “strong” for 144hz. How many ms the monitor will do realistically? I will see the improvement or I will see ghosting anyway?
    2) I see that the display have a wide gamut . It is possible to low the brightness and at the same time have a sRGB experence like my current monitor?
    The user setting of pcmonitors are a srgb experience at 35brightness?
    Thank you in advance for reading my question^^.



    There are plenty of threads discussing this model – certainly no need for another one, so I’ve merged yours with this thread. 🙂

    1) Pay no attention to specified response times. We don’t write reviews and record videos in such detail so users can ignore that whilst expecting everything to be wrapped up into a tiny misleading figure. Things aren’t that simple, it would save me a lot of time if they were. The AOC 24G2U is vastly more responsive than the ML239H, accounting for both pixel response times and refresh rate. Look at the pursuit photographs, which clearly demonstrate the benefits of increased refresh rate (and frame rate) on perceived blur levels. The ML239H is not as responsive at 60Hz as the AOC – let alone the fact it’s only limited to 60Hz and there is significant benefit from an increase beyond that. Even if you compare that fast TN 60Hz reference (XG240R @60Hz) to the AOC at 144Hz, you can see clear advantages from 144Hz refresh rate.

    2) No, as per the review the sRGB emulation (‘Color Temp. sRGB’) setting locks off brightness control. I’d advise you read the review more carefully as it’s quite clearly not an “sRGB” experience which this model offers nor is that what our ‘Test Settings’ would achieve. If you’ve got an AMD GPU there is a setting in the driver which may offer the sort of look you’re after. Didn’t have time to cover it in this review, but we’ve looked at it in others (reference). You simply need to open ‘Radeon Settings’, navigate to ‘Display’ – ‘Color’ (little icon towards the top right) and press the ‘Color Temperature’ toggle so it reads ‘Automatic’ instead of ‘6500K’. It will act as an sRGB emulation setting of sorts.

    I appreciate English may not be your native language and I don’t meant to come across as harsh. It’s just that I spend a lot of time and effort on these reviews and I appreciate if users take some time to read/watch them rather than asking questions which are answered in the review. I know they’re long and there’s a lot of information to absorb, but hopefully this post clarifies your questions.



    It seems that lot of people had this issue with the Acer. You can see this on Reddit… it’s very annoying…

    Yeah I ended up returning mine it was just too annoying to deal with. It would reset at any signal loss. Like if you run a full screen game that is locked to 60hz it needs to request the full screen draw mode from windows and your monitors lose signal for like half a second while the GPU context is locked by the renderer and that would reset the colors. Alt tabbing out of the game the same thing would happen and reset the colors.

    Acer offered for me to send it in for “repair” but I really don’t want to deal with it – especially with how busy this time of year is for everyone.


    In my country the ViewSonic XG2405 is starting to be sold, but I just can’t find any review, info or feedback about it. Do any of you have it or know something about it? It looks so good (144hz, IPS, 1ms; like the AOC 24G2).


    Hi LexGM,

    I’ve merged your thread with this one as there is a little discussion on it here. It will be using the same Panda CELL (panel minus backlight) as the AOC 24G2(U), with a narrower gamut backlight. So less vibrant/saturated colour output but presumably similar contrast. ViewSonic usually tunes pixel overdrive well. Might be an interesting model to test, but I’ll wait for broader availability first and it depends if we get swamped with other models as well. I’d rather look at one of the models using a novel panel, like one of the 24.5″ AHVA options. We’ll have a news piece up on that one shortly, it’s been on the to do list. 😉

    Update: ViewSonic XG2405 news piece now live.


    The 24G2(U) is currently in stock in the US. It has been in and out of stock a few times over the weekend, hopefully it stays in stock for a good while now.


    Hello all!

    I recently purchased the ASUS VG249Q and wanted to post my thoughts. I already purchased and returned the AOC 24G2 and Viewsonic XG240R but returned them due to QC issues and horrible eye strain/headaches (mod edit: seems very generalised and potentially misleading to those reading – better to be specific about which issues apply to which model and how long you tried to adapt to them for). My particular ASUS unit has no dead pixels and extremely minimal IPS glow/BLB. However, I am having a hard time adjusting to IPS colors and was wondering if anyone else has this monitor yet? I haven’t found a single review online so far. I’ve tried calibrating it as best I know how but I’m having trouble getting it to look just how I want to. No headaches yet either!


    Sorry, I’ll be more specific about each one.

    24G2 – Immediate and pronounced headaches regardless of brightness/contrast setting. Horrendous GSync/Brightness flicker in almost all games I play. I didn’t test this for more than a few days before it went back. I couldn’t deal with the headaches.

    XG240R – Somehow the Gsync flicker was even worse with this one. The colors were pretty okay after calibration. It felt responsive and good to play games on but the headaches came back after 3 days.


    I appreciate the break-down of issues per monitor. Although I have to say, I have no idea why you were observing some of those issues. Based on my testing of the 24G2U and user feedback on that there is only occasional flickering. And it’s usually during large frame rate fluctuations or particularly low frame rates. On the XG240R it’s more or less restricted to low frame rates. It sounds like you were getting it over a broad range of refresh rates, is this correct?

    So to double-check – what GPU were you using and under what frame rate range did you observe the issues?

    As for the headaches, there are many potential factors at play here. However; the ASUS VG249Q uses the same CELL (panel minus backlight) as the AOC, so that narrows things down nicely. Must’ve been something about the backlight you didn’t let, perhaps just the overall saturation levels. Or perhaps something about how the monitor was set up.


    I don’t think I’m doing a very good job here of explaining myself. Let me try once more! 🙂

    For the 24G2, I noticed it in the menu areas of Destiny 2 and Wreckfest. It was particularly distracting. I felt the 24G2 also had too wide of a color gamut for my personal tastes. I followed the Blurbusters guide for setting up GSync properly and this flicker occurred over a broad range of refresh rates.

    My current system is a 9600k/NVIDIA 1660ti. I typically have zero issues keeping a consistent framerate in the games I play. This VG249Q was immediately easier on my eyes, even at the stock brightness/contrast setting. I have no flickering in any menu in any game at this time. Extremely minimal IPS glow and BLB on this unit as well. I fully admit that my issues with the previous monitors may be a “me” issue and not specifically those units themselves.


    I felt the same as the user above me with the AOC.

    And this is simply due to the coating of the AOC monitor, fonts are anything but sharp the 25 from Asus with AUO panel is even more blurred…
    And that gets worse the more finished the eyes are…
    (by the way, I think it’s a pity that tests are done on the coating, but not on any impairment by the coating regarding sharpness etc.)

    The result was eyes and headaches…at least from the eye the next day.

    The AOC was otherwise such a good monitor and so little Glow which I rarely saw with IPS.

    I just had to send it away, I could not do otherwise…

    But now I need 144Hz again… I can’t do without it.

    My last hope is the ViewSonic XG2405 has the same panel?

    I hope it is understandable my English is bad…


    by the way, I think it’s a pity that tests are done on the coating, but not on any impairment by the coating regarding sharpness etc.

    What exactly are you suggesting? We’re the only monitor reviewers who actually mention the coating in much detail and always mention the effect it has on the image in terms of level of graininess. It’s mentioned in enough detail to bore some users, in several places throughout our reviews (both written and perhaps moreso video reviews). There is no way to quantify something like “impairment regarding sharpness” (aside from mentioning graininess, subjectively and talking about haze value as we do). Because that “impairment” is an individual and subjective thing.

    The screen surface used on the 24G2(U) is actually slightly less grainy than that used on the vast majority of 144Hz Full HD monitors, including all TN models and any IPS-type models using different panels. Including the VG259Q, as you discovered. Most users are absolutely fine with even ‘grainier’ and higher haze screen surfaces and certainly much ‘worse’ surfaces than the 24G2(U) uses. I don’t like them myself, which is why I explore this aspect in reviews in is much detail as I do and as much as I reasonably can. If you don’t like the screen surface of the 24G2(U) then you’re out of luck, certainly with the XG2405 that uses the same CELL as covered already. You’d need to consider a VA model like the AOC C24G1 instead or even better switch to a WQHD or higher resolution option.


    Hello, doesn’t change the fact that the AOC is simply strenuous, it can also be that this is a side effect of the fonts if the eyes are simply overstrained. The coating shouldn’t be a criticism, but I know other monitors that are not as matt as this one. And the user above us has basically had the same appearances and gets along with the Asus much better despite the same panel. And I find one or the other in the www. that is the same with the AOC. VA is out of the question thanks to the suppixel structure. And VA doesn’t please me metaphorically either. I will test the VS and the Asus in the hope that one of them will work better.


    There are no monitors directly comparable to the 24G2U that are “less matte” (i.e. that have a significant lower haze value or smoother surface texture). If you’re expecting that, you’re setting yourself up for disappointment. “Dramabomb” had issues that were caused by other aspects, because the screen surface is part of the CELL or panel and doesn’t vary between screens using the same CELL. It’s correct that many intertwining factors can cause viewing comfort issues. Finding a screen surface troublesome coupled with not getting on the brightness, backlight or other aspects of the image appealing could certainly cause issues.


    Well, the AOC AG271QG also has a different coating than the XF 270 despite both having the same panels. Anyway, I just wanted to say that the AOC is also exhausting for me. The user just gives me some hope. You have to test it yourself anyway.


    Actually they don’t use the same panel, hence the differences. The AOC AG271QG uses the AUO M270DAN02.3 and the Acer XF270HUA uses the M270DAN02.6. As I said, though, it is a combination of factors you need to consider so you’re absolutely right to give the ASUS VG249Q a try and see if it works out better for you. It’s unfortunate ASUS are so selective with their review samples as I wouldn’t mind reviewing that model.

    Edit: No further discussion on the topic of screen surface variations, unless to add specific feedback after hands-on testing. The AOC 24G2(U) and ASUS VG249Q both use the Panda LC238LF1F CELL. The screen surface is part of the CELL, a 25% haze ‘medium’ matte anti-glare screen surface which comes as part of the package. There can be variations due to different sub-variants of a given CELL (or panel), but there are no known subvariants of this Panda CELL and it is a standard spec. All the monitor manufacturers (or panel assemblers – TPV etc.) do is add their own backlight solution, that is the only change differentiating the ‘panels’ used in these monitors.


    I really wish manufacturers would start employing a decent anti-glare film as you see on 4k tv’s. The aggressive layer that’s used really takes away from the image.


    I agree. I’m a big fan of glossy or near-glossy screen surfaces and they are far too rare on monitors. I recently posted something along these lines with reference to 27″ WQHD models, although it was more of a general comment really and certainly applies to the 24″ Full HD options as well.
