Is the 120Hz ULMB2 mode usable on consoles over HDMI?

Yeah, same as the 60hz ULMB2 mode.

Accepts 4K input on it too, along with 1440p. Seems to have all the HDMI 2.1 things ticked off apart from ALLM but I think that's more relevant to TVs because of their picture modes.

pulse width 40 120hz, 1920 pixel/s vs standard 100 pulse pg27aqn 1920 pixel/s

this asus pulsar, the bug is still happening, monitor goes to sleep, launch a game, and black screen, have to tab out, turn off and re-enable pulsar to fix the issue

I've tried replicating this on my Asus but genuinely can't. I dropped my sleep timer down to 1min, let it go to sleep, then moved my mouse to launch a game. Pulsar remains enabled throughout.

Running a 5070Ti for what it's worth as a comparison, is this a 4000 series quirk with the lack of display heads?

Same here, can't reproduce this. Not on any firmware version with RTX 5090 with multiple drivers under Windows 10 OS.
It always boots up correctly, into 360Hz, into Pulsar, and into HDR if it was activated, while sticking to 10-bit wide gamut.

Side note, recently it has been very warm, been using the monitor in HDR mode when it was 30°C inside, the monitor had no overheating troubles as expected with this, despite the warmer bezels with HDR mode. I think we shouldn't need to worry about that one-off quirk a few people had.

So far 1.1.8 firmware is working well here, have got no additional notes for as of now.

Yeah, the heat / warmth on the bezels is the only part of this monitor that concerns me (although it appears that it's an issue across all of the Pulsar monitors).

I'd be happy if we saw a revision down the line that had slightly thicker bezels that would allow for the monitor to feel cooler - or even active cooling. I suppose it's more noticeable at the minute as it's summer - so any additional heat just adds to it! It's probably on par with my OLED for how 'warm' it feels, although all the warmth in the OLED is on the rear of the panel and the heatsink.

Yea I also reduced the brightness to 300 because of the heat. I am anyway gaming in my basement with some indirect lighting around. So 300 is far more than enough. But if it wasnt for the heat, I would run it on 500. I like bright screens.
In bright rooms, this could be a problem I assume.

i wish they make 240hz and 360hz ulmb2 like 120hz mode

120hz is amazing, but at the end of the day, 120hz doesnt feel great for fps games with a mouse

I don't understand something. If the motion clarity is so good, why doesn't it feel good?

i recently re bought old pg248qp, because it was cheap, theres no monitor as clear as it (crosstalk aside/double imaging), for some reason i find the 500hz mode clearer than 540hz mode, or better tuned or something, if you account for the ufo 33% faster, so 1440pixel/s is basically 1920 pixel/s on a 1440p monitor, its really impressive, and thats on 100 pulsewidth at 500hz

Thank you for doing 1920px/s UFOs of the ULMB2 mode of the PG248QP!
It's difficult to find such data online!

Higher refresh rate makes chasing lower pulse on intervals easier.
I believe the ULMB mode on that model can get quite a high effective motion clarity due to the adjustable pulse width.
Likely easy to obtain +3kHz.

Be mindful that the refresh rate you've tested (500Hz) is actually slightly faster than 1440px/s, as TestUFO is a approximation.
It's likely ~1500px/s instead (3px / frame)
1920px/s would be 2000px/s instead (4 px / frame)

I wouldn't be surprised if even 3000–4000 px/s is clear on it.
