NVIDIA G-Sync Pulsar monitor - Asus ROG Strix XG27AQNGV

Also it would be nice to have some images of full screen crosstalk. Does crosstalk improve/worsen by lowering/incresing pulse width? Is the phase optimal when doing so? U can use testufo, or if u need sync track use this pattern image for Smooth Frog.

This help? 1920 pixels per second, PW100, 120hz.

crosstalk is minimal, even harder to see at lower pulse widths.

I have taken pursuit photos at Pulse Widths 10, 20, 30, 40 and 50 at 1920, 3840 is difficult with an iPhone, ill post them later when I'm back at the PC.

I think I took them right, 1/30 shutter, 120fps video, followed the screen so sync lines were straight.
PW 10 to 40.jpg

Could you test the same PW's in intermediary speeds up till 3840px/s?
For example:
https://testufo.com/ghosting#pps=2400
https://testufo.com/ghosting#pps=2880
https://testufo.com/ghosting#pps=3000

Judging from the pursuit photographs you've done, the eye-tracked motion clarity does indeed look lovely.
One of the few good 120Hz strobing implementations on a 1440p image resolution.
Dare I say it rivals CRTs in terms of effective motion clarity, without it's detriments.

Maybe some other time as it’s not easy with an iPhone, no promises. I want to play games on it right now!

I am sad to report that 1.1.8 does not solve the no pulsar after display sleep issue. At least not for me. I still have to run the monitor in 240Hz desktop to work around the issue. This is on 4080 SUPER.

Could you provide additional details on how you are reproducing this issue?

• When the issue occurs, does only the display enter sleep mode, or does the entire PC also go to sleep?

• Are any additional monitors connected to your RTX 4080?

• Have you changed any NVIDIA Control Panel or NVIDIA App settings from their default values that could affect display behavior (for example, custom color settings, power management, or other display-related settings)?

• Do you power off the monitor when not in use, or do you leave it in sleep mode?

• Approximately how long does the display need to remain in sleep mode before the issue can be reproduced after waking it?

• Are you currently using the latest NVIDIA driver (610.62)?

• Are there any other steps or conditions that consistently help reproduce the issue?

You think the reason they are hesitant to release standard 240hz and 360hz high quality ulmb2 because they need people to upgrade to there newer models down the line or because people with amd gpus who will just use this mode over pulsar that they can't

If we are to trust their word, it's because of unacceptable crosstalk, as it has been mentioned before in the thread.

At 60 and 120 Hz, Global Flash can look real good without much double image. FW 1.1.7 will show that for ULMB 120. But at 240 and especially 360 Global Flash would have significant double image.

Hi Manuel,

Sure.

• The PC itself is set to never sleep or hibernate. The issue occurs after the monitor(s) have slept and been woken up.

• I have another DisplayPort 1080p monitor in portrait mode 60Hz, and a HDMI 4K TV 60Hz attached.

• All the Nvidia app settings are default. I have tested with Power set to both Normal and Maximum Performance.
  I never power off the monitors or the PC. Only the monitors sleep after 25 minutes idle.

• You can sleep the monitor to the point that the screen is completely black, immediately wake it, and the issue will occur. So, it needs zero time. Also, if you don't launch a game for hours the issue will still occur until the monitor has been power cycled.

• I am using 610.62 driver.

• The monitor needs to be set to 360Hz on the Windows desktop. The games I have, Battlefield 6 specifically, need to be set for full screen exclusive 360Hz. After the monitor sleeps, you wake it and launch the game you receive a black screen with a horizontal band of light that flashes periodically towards the bottom of the screen. After you power off the monitor using the power button on the monitor and then power it back up, you can launch the game without issue. If you set the desktop to 240Hz and leave the game full screen exclusive at 360Hz, the issue will not occur after monitor sleep. This is the workaround I am using.

I hope that helps. I'm happy to provide any other information that might be helpful.

Finished the 1.1.8 update and had an hour or so playing the Finals on PS5 Pro (120hz pretty much always locked) - and wow, the 120hz mode is incredible. Completely surprised me with how crystal clear it all is. I need to try some more games at it to get a proper feel for it but the first impressions are fantastic.

Great to see the reduced input lag at 240hz as well, I mainly keep my Pulsar monitor at 360hz but cap all my games to 240fps as I've found the clarity from 240-360 isn't a huge increase - but the GPU utilisation and temperatures saved are much more noticeable to me.

Really great to see the continued Pulsar support from Nvidia, the NV App per game 'setting' (ULMB2 vs. Pulsar etc.) is the one I'm really looking forward to. I often toggle Pulsar on and off via the OSD mainly just to stop the monitor feeling so hot when I'm not actually using it for games!

Hi

Installed 1.1.8

How do I enable the 120 hz ULMB2 mode? I see the ULMB 60 hz option under "G-Sync Processor" When I use the tumbstick to enter the Asus monitor utility.

Want to try out some Switch 2 120 fps demo's see if I can enable it, but no clue how to???

Thanks in advance.

I just updated to the 1.1.8 firmware, thanks for the continued support Nvidia.



Firmware 1.1.6 seemed to work really well for me on the RTX 5090 thus far, all the way up to the newest 610.62 so far under Windows 10 22H2 x64

The only two things I had noticed on 1.1.6 was:
1. Random very bright white flash (maybe microstutter/frametime spike related?) I think I've seen it occasionally on some other games but it was so very sporadic that you don't think much of it and move on.

2. The weird image retention issue by running https://testufo.com/ghosting for a minute and then close it.
Post: viewtopic.php?p=125300#p125300

I don't really know enough to say what this could be caused by.
Point 2 above is still happening on firmware 1.1.8

Is this a limitation of the display tech (IPS?) or is this a bug that could actually be solved?

[Angel Soler]

I’m really loving everything I’m seeing here
This is a great update
The only thing left for me now is an update to ULMB 2 at 60 Hz and a fix for the input lag.
Once that happens, I’ll buy the monitor again without hesitation.
