TUF Gaming VG34VQL1B artifacts / shimmering

[Radical_53]

Hi,

I've been having a blast with this monitor. Speed, color reproduction, even it's limited HDR capabilities -> perfect upgrade.

I do have two issues though:
1. It doesn't seem to send any form of HDR certificate, which could be the reason I have to switch HDR on and off manually all the time.
2. Blue/violet artifacts/shimmering in dark spaces at higher speeds.

The 2nd is something I didn't notice at first, but now I can't seem to look past it anymore. It's almost like chromatic abberations in photos?
I've been using VA monitors for the past years and I've never experienced something like this.
I tried to play around with the OD setting a little but it didn't really change much (that I'd notice).

Any advice?

There is a WHQL driver & ASUS DisplayWidget Lite, have you tried these ?

Hi,

thanks. Yes I do have those drivers installed. I've tried different things, like enabling and disabling G-Sync/FreeSync/VRR, various overdrive settings, 8-bit and 10-bit color depth.

PS: I have no idea I should make a video or something, but even scrolling this site up & down quickly, white letters on black background, will make the letters turn into "rainbow" while they're moving. Letters stay clearly visible, they're just not white anymore.

Overdrive seems to affect the artifacting. Several other people seem to be having this issue as well:

I changed the cable for a new DP 1.4 version, the problem persisted.

Only turning off OD completely when HDR is enabled will get me rid of the artifacts. Hopefully there'll be a firmware update to address the issue.

Hello,

Up of this tread.

I have V13 firmware on my screen asus VG34VQL1B , what is the latest version ? How we can get it ?
Thank you.

V13? Interesting. So far (mine included) all the screens I knew had V12.

[Radical_53]

Well, I just received my replacement screen and it comes with firmware V013! But now I feel like an idiot as it doesn't seem to allow me to turn on HDR.
With the screen completely reset, I never had a setting that prevented me using HDR?

Second replacement arrived today, firmware V017. Still no HDR, still greyed out.
