NVIDIA G-Sync Pulsar monitor - Asus ROG Strix XG27AQNGV

I absolutely love this monitor. Best apex monitor I ever had. hands down. Still have some questions ^ but regardless

I mean by default you can run the monitor at 360 hz 8 bit color on a 3080 BUT some users have reported some black out issues due to being forced to run DSC to hit that refresh, resolution and color depth combination. Try it and see, worst case you can definitely run it at 240 hz and still have a similar experience. Pulsar doesn't work as well at higher fps than it does at lower frame rates ironically I normally play below 200 fps and everything looks incredibly clear compared to even my OLED monitor next to me.

Reducing refresh rate to 240 Hz does improve the situation, no more random black screens within games. But the alt+tab black screens are still there. If running at 240 Hz is really an option for anyone, I strongly recommend disabling displaytiling (see page 63 here). Everything just works better then.

Nvidia is aware of this situation and hopefully working on it. This is not a pulsar thing. If they get this under control they would improve a bunch of monitors.

In the next firmware update Nvidia mentioned they are reducing lag in the 240hz modes.

I performed a reinstallation this morning because I wasn't entirely sure if it had been applied correctly with FW 1.1.6, and I've noticed that it now correctly displays the FW version on the monitor's OSD: MCM103(V1.1.6).

Interesting, thanks.
I know the update did apply successfully since the 120-180 range is working fine now, was just curious why the firmware version sticked.
Maybe they did an inbetween fix, but not too bothered by it.

Interesting. Could it be that with 10bit color and 360 Hz, even RTX50 cards have to use multiple pipelines and run into the same problems as RTX40 cards with 360 Hz 8bit?
In this case... DSC is (again) not the actual problem.

You could try to disable the tiling via registry. With 8-bit color the 360 Hz mode should still be available. With 10-bit it could be gone.

RTX 50-series cards do not share the same limitation as DP 1.4 videocards did with DSC, that means even with DP1.4 monitor and cable you can use DSR / DLDSR (or custom resolution) and not have the same black screen issues as RTX 40-series and older experience.

You can also use 10-bit with VRR/Pulsar with HDR no problem. With DSR 'hacked' to 8K resolution you even get to keep the 360Hz output, I think at 16K it may be 60Hz but that is an exceptionally high resolution not workable in many games.

It runs on all RTX-50 series cards on a single display pipeline even though DSC is still active to compress the image to send it through to the display but the GPU side is well capable enough to handle all the bandwidth required.

So whatever issues you experience on DP 1.4 videocards may disappear using a newer videocard.

To circle back a little bit to my previous question: which driver would you recommend for the firmware 1.1.6 and an 5090 GPU?

I would probably advice to still install the latest one, unless you're experiencing issues you didn't on previous ones which can at times be a bit of a mixed bag between GPU architectures, though recently they have implemented some security updates for the drivers in May so I would still make sure to have atleast that version or newer installed for security.

I did have to install the 610.47 driver completely clean because I had issues with GTA V Enhanced not booting due to some strange underlying driver issue which may have been a result of doing multiple GPU driver upgrades in a row without a clean install which caused below crash errors in the launcher error logs:

[DISPLAY] [23800] [gamelaunch] Game exited with code 0xc0000005 (3221225477)

So what I did was wipe 610.47 completely including leftover folders, registry and physx + legacy physx.

Then I reinstalled the previous driver, re-imported my driver profiles with Nvidia App override bypass so I can control DLSS overrides in any game without Nvidia App resetting the driver profiles for those particular games.

The game functioned again afterwards with all my programs open + RTSS overlay.
After that I installed the 610.47 driver over it and install Legacy PhysX without doing a clean install and things are fine again.

Noteworthy, I had some stuttering issues on the Pulsar display in DOOM TDA with the previous few drivers on 3x/4x MFG mode, but that looks to be solved now in 610.47 with maybe the only leftover 'issue' being if you switch from a Legacy native FPGA G-sync monitor to the Pulsar display that 4x MFG may still exhibit some frametime stutters until you retoggle the MFG settings ingame.

Sometimes MFG behaves differently on the old G-sync monitor versus the Pulsar monitor even on different multiplier modes, but the recent updates in the drivers regarding multi-monitor with MFG and V-sync fixes may have contributed to this improved stability.

Only RTX-Remix games like Portal and Half-Life 2 still seem to stutter on 4x MFG mode (2/3x is smooth) making the motion feel like half the smoothness on 4x mode despite higher FPS even on DLSS Ultra Performance on a RTX 5090 which is a bit questionable why this happens when games like Cyberpunk 2077 have zero stutter doing even 6x MFG.

The 610.47 driver has not yet fixed the Stand-by -> wake up for G-sync on the PG279Q essentially deactivating it when woken up but that is to be fixed in the future, Pulsar does not show this problem.

But in short I would probably still go for 610.47, albeit a clean install and re-import your driver profiles if required through Nvidia Inspector.

I have a RTX 3080 its not possible right to make custom resolutions and have Pulsar enabled on 360hz 1440P 8 bit? is 240hz max?

I mean by default you can run the monitor at 360 hz 8 bit color on a 3080 BUT some users have reported some black out issues due to being forced to run DSC to hit that refresh, resolution and color depth combination.

Standard the monitor runs great on my 3080 8 bit or 10 bit 360hz with Pulsar only problem I have is that there is no custom res option. Is there a way to get the custom resolution available with Pulsar on 360hz 1440p?

[MSIfanboy]

Yes you can make a cru custom resolution and use sre also, I used both, and pulsar still works , I had to turn off scaling in the osd , image, aspect control, scaling off

Yes. Follow the guide on page 63, disable tiling. Besides the snappier operation without any alt+tab black screens this will allow you custom resolution and DSR (super sampling). Both are deactivated by default using rtx30 and 40 cards. I assume DSC (compression) is also deactivated.
You can run the display with single tile mode up to 300 Hz via custom resolution (8-bit and 10-bit). However, Pulsar only works with 240 Hz.

When tiling is disabled, you should not play around too much with adding other screens on the fly (like plugging in a new screen while running windows). That might cause some blue screens. After a restart however all screens will work then.

Tnx so Pulsar only works with custom resolutions on 240hz? I am confused cause msifanboy says he can use cru to make a 360hz custom res with 360 Hz just above this message

[daviddave1]

Tnx!!! so Pulsar works with custom resolutions on 360z? That's good news!! I am a bit confused though cause mawi says he can only make a 240hz custom res just above this message.

yes i am running 24.1 inch mode, pulsar works, scroll back to my former posts a few pages back

tnx aloth! I wil try this soon!!!
