24” 1080p 144hz IPS monitors are finally here!

The 24G2U supports LFC or frame to refresh multiplication below 60fps, so there are no stuttering issues related to mismatches below that. The issue was if you are frequently hovering around 60fps, going above and below the boundary. The handling of the lower boundary and when things cross it, alongside variable overdrive, are two key advantages of models with an actual G-SYNC module. It really depends just how frequently you cross the boundary and how much the slight disconnect in the experience would bother you. In my view, on a 144Hz monitor getting below 60fps is a rubbish place to be regardless of tearing and stuttering. The ‘connected feel’ and perceived blur levels are much worse. Of course ‘stuttering’ would add insult to injury, but for me that’s just one factor which would sour the experience and if it’s an occasional one I wouldn’t really mind.

I’m not sure why the floor of operation is different, there are a few models I’ve seen this on with ‘G-SYNC Compatible Mode’ vs. FreeSync. CRU might work, but I can’t confirm that from my own testing. It isn’t something monitor manfuacturers like me to openly discuss or test (even though it might help in this case as the monitor should be capable of a lower floor of operation than 60Hz).

I’d advise reading earlier posts on this thread as that’s covered. Here and the proceeding page, for example. If you’ve seen it confirmed that it runs with a 48Hz floor of operation using ‘G-SYNC Compatible Mode’ (and not just ‘FreeSync’, where the AOC has a 48Hz floor as well) and are happy with less vibrant colour output, slightly worse pixel response tuning and a slightly granier screen surface then it might give you a better experience.

I used to own a Samsung S27A750D and used that as my main monitor for quite a while. I liked the ‘Ultra Clear Panel’ surface used on that and also wrote a little about it for our matte vs. glossy article. Although the T27A950 was used as the example there (same surface). There is nothing comparable on the market at the moment. The upcoming Philips 328M1R will offer a good (effectively glossy) screen surface. Outside of that the WQHD IPS-type models and Dell S-series (S2719DGF etc.) offer the lightest matte surfaces. In keeping with this thread, the ~24″ Full HD 144Hz IPS-type models aren’t comparable and are more of a medium matte. Although the finish of the models with the 23.8″ Panda panels is smoother than competing TN models at least.

I look forward to your thoughts on the XV253QPs when they arrive, Orof. But I need to clarify a few things, to set realistic expectations for yourself and those reading this. The ‘Normal’ overdrive setting seems to provide quite strong overshoot as well. At least it did on the test sample I saw, for the transitions used on TestUFO. I actually found this more noticeable to my eye than it appears in the pursuit photo I took. And even then it’s pretty clear. Sensitivity varies and it won’t bother everyone.

The panel response time specification can be pretty misleading, because in practice some transitions will be faster and some slower compared to the Panda panel. But a lot also depends on how things are tuned, as above. The the AOC offers good flexibility (and tuning) with its pixel overdrive. Just looking at the transitions in ‘TestUFO’ the AOC does give more powdery trailing but the Acer replaces this with overshoot. Some will prefer one, some the other. The same applies to the colour gamut, with the 24G2(U) being more saturated and vibrant and the Acer more of a ‘rich and natural’ appearance.

And the 6-bit + FRC vs. ‘true 8-bit’ thing is really a non-issue in practice. If you told users the AOC was true 8-bit they’d believe you. Likewise if you told them the Acer was 6-bit + FRC as well they wouldn’t bat an eyelid. The Panda panel also has a smoother (less grainy) matte screen surface. I’m not trying to put a damper on things, just clarifying a few points based on my own experiences. You may well love the experience that the Acer provides. I’m just trying to point out that it isn’t a one way street and some of its advantages ‘on paper’ don’t necessarily translate in practice.

Your impressions (and those of your brother) will be very welcome indeed. And much more useful than my own impressions really, because they were based on an early pre-production sample at IFA back in September 2019. It was at 144Hz where the overshoot was observed, but it’s definitely possible that Acer has re-tuned things. I gave them a little feedback about it and they did mention that the monitor was still needing some “optimisations” before it went on sale. If you’re able to confirm this with TestUFO and other testing that would be great. 🙂

And thanks for posting those videos from another user. I hadn’t seen them before. They appear to show much lower overshoot than the unit I saw on TestUFO and from the video at least things appear nicely optimised for 144Hz performance. There’s still some overshoot for the medium (middle row) and light (bottom row) backgrounds but from the video at least it appears pretty light.

That’s a very subjective thing and it’s explored in quite some detail in the review. There’s really no difference for me between how I like games or movie content to look. I’m exposed to a wide variety of monitors with various capabilities and can adapt either way. You need to weigh up your own preferences for saturation levels and vibrancy vs. a more ‘natural’ appearance. I’d make the argument that neither solution is perfect, personally I find sRGB too restrictive and like a bit of extension beyond it. There are far too many shades in the real world that aren’t captured by such a small colour space. I can tolerate extra saturation and generally prefer that myself, but my preference would actually be for a wide gamut that’s mapped properly – as you get on some monitors under HDR, which is out of the question in this case.

I hope you enjoy it! Just subjective impressions would be a great addition to this thread. If you’re able to, pursuit photographs using TestUFO and your favourite response time setting on the ASUS would be great. You can do this by taking a video on a decent smartphone camera, if you have one, or a normal camera with decent resolution video recording. You simply track the UFOs as best you can from left to right, trying your best to match the movement speed with the camera or phone movement. You can do several passes and hopefully you’ll be able to get some good frames showing the perceived blur. I discussed a few things to look out for with another user when doing this sort of testing here.

What did you have in mind that you feel could be better? The AOC is an excellent all-round performer for the price. If it’s “exactly what you want”, what is the point in waiting and what would you be waiting for? An upcoming model I’m particularly interested in is the Acer XV253Q X, but that’s 240Hz. There’s really nothing in the 144Hz IPS-type flavour that I feel would be worth waiting for, or that would be substantially different to the alternatives already available with a narrower colour gamut than the AOC. For many, the wider gamut of the 24G2(U) is actually a desirable and unique selling point, but it’s not for everyone.

So today i got the Asus TUF VG249Q and the ViewSonic XG2405. I think they both have the 60-144hz VRR range. I’ve tested CSGO with 2 bindkeys to drop the frames to 50 and then to get it up to 144.. I didin’t notice any stutter or tearing going out/in range rapidly. I used a GTX1080

On the ViewSonic XG2405 OSD there is a way to show the current refresh rate? I didn’t find it in the OSD and google doesn’t help.
