Thank you very much , Brownvim, for your kind wordsbrownvim wrote: ↑11 Apr 2026, 11:31Thank you for the very detailed and honest write-up — it’s really valuable coming from someone who owns both the XG2431, the XL2566K, and multiple CRTs.
I have some quick questions if you don’t mind:
1. Did you notice any difference in input lag with 60 Hz ULMB2 on versus off in your Leo Bodnar tests? (i.e. interested in how much extra lag the strobing adds)
2. Would you be able to test the lag at both 10 pulse width and 100 pulse width?
3. How's the flicker in comparison to the XG2431 and XL2566K
You can turn off the ambient light sensor and ambient colour sensor for a brighter picture. On my Acer it gives a noticeable boost in brightness without hurting clarity.
Really appreciate you taking the time to test the monitor and share your thoughts.
I am very happy to do this, because I feel genuinely grateful to this forum. It is the most serious and professional forum I have ever seen, and in a way I feel indebted to it, because many members here — including you — have helped me a lot. So I am glad to contribute in any way I can, and if anything I share is useful, that makes me very happy.
Here I am sending the different photos you asked for:
* one with **ULMB disabled**, where as you can see the result is **11.9 ms**
* and then the measurements with **ULMB at 10, 30, 50, and 100**, so the full range can be seen
That way, I think it helps show quite clearly, as you rightly said, what the strobing is adding.
Regarding the **flicker**, it is true that it does not bother me personally at all. I have been used to CRTs all my life, so it feels completely natural to me. If I had to say which one seems to flicker less, I would actually say the **ASUS**, even though it is a **27-inch screen** and the XG is only **24 inches**. In fact, I think there were moments when I noticed the flicker more on the **XG**. Again, flicker does not bother me in either case, but if I had to choose, I would say the ASUS seems slightly better in that respect.
As for the **24 ms of input lag**, I want to be fair: that is not a high number in absolute terms, and I am sure many people would find it perfectly fine and enjoy the monitor without any issue. I know I am especially obsessive about these things. I am very sensitive to motion blur and input lag, so I judge these displays from a very demanding point of view.
Still, when playing more demanding genres — especially **fighting games, shoot’em ups, or platformers with very tight jumps** — I do personally notice that extra lag, especially in **fighting games**.
That said, if I had to recommend this monitor to someone looking for **motion clarity at 60 Hz**, I would absolutely say it is **wonderful**. For console use, it is basically like the **XG**, but with **virtually no crosstalk** and much higher brightness.
As for the **XG on PC**, when using **Quick Frame Transport** and **CRU**, it is truly amazing. In that scenario, to me, it is basically perfect. Yes, it has lower brightness, but that does not really matter to me because I play in an almost completely dark room with no window — what I call “the Dungeon.”
So overall, yes, I would definitely recommend this monitor. I also agree a lot with **John Linneman from Digital Foundry** when he said how incredible it is to see an LCD with this kind of brightness and this level of motion smoothness. In that sense, it really is something special.
If this monitor had **16 ms instead of 24 ms**, I honestly think it would be **almost perfect**, and I would absolutely be willing to pay **3,000 euros** for it.
I hope my measurements and impressions have been helpful.
