Hello everyone, i wanted to disable Text Clarity as some people suggested here, but i don't seem to have that in my settings

Do you guys know why?

Image->Clear Pixel Edge

As previously mentioned, it's not showing up

Have you updated the firmware? https://rog.asus.com/monitors/27-to-31- ... desk_bios/

Hi all,

Bit of a long message. Switched my monitor and PC on one morning and I noticed the colour was set to SRGB but showed wide gamut, upon checking the osd settings, changing from SRGB to DCP3 and Wide gamut, the screen would "react" but not actually change the colour profile. Additionally, the colour temperature setting would not work, setting 4k, 7k etc. Nothing changed.

I took a flash drive and tried to update MC104 (Firmware already on MC104) but it would not flash, the screen would switch off and back on again. This however fixed the colour and settings issue, but another bug persisted. The only way I can describe this bug is somewhat of a screen jolt from left to right, like extreme "pixel move" if that makes sense. It's extremely jarring and its most definitely not related to pixel shift.

I have updated the firmware via the USB cable but this jarring screen shifting motion still persists. Any thoughts ideas or anything I can try? The monitor is around 2 months old.

@RealNC Hey bro, I promise this is my last question about VRR o.o

Do you know if VRR causes gamma to change at low fps on IPS monitors too and we just can't see it because it can't show darker shades as well as OLED?

I have decided just to play with VRR on default settings and try and ignore the slight brightening of dark areas, the flickering was never really an issue with me anyway. I tried using Reshade Levels.fx to artificially darken dark areas instead, it kinda works but obviously not the same. After fiddling between the VT tweak and normal VRR, the smoothness is just too good to worry about the gamma change.

None of the IPS monitors I used had that issue. They can show dark shades just fine, just not total blacks.

oh damn, I thought the VRR flicker/gamma was a thing inherent to VRR but it just wasn't visible on IPS or something. Idk why more people don't talk about the raised gamma issue cause IMO the flickering isn't the worst part. We buy these OLEDs because they're advertised as deep black colours, but they don't tell you that VRR ruins it to an extent. All I heard about was flicker, I know that and the raised blacks are related but not once did I hear about the gamma change from a reviewer

The flicker is caused by the gamma change though. If an OLED doesn't have VRR flicker (like some laptop OLED screens,) it also doesn't have gamma change.

If you toggle the RTSS frame limite on/off for example with a hotkey, and have set it to 60FPS, then when you toggle it on and off you'll get a good understanding of why there's flicker. If you press the hotkey really quickly to rapidly toggle between 60FPS and 240FPS, what you get is close to what flicker is. During frametime spikes and unstable frame rates, this switching between different refresh rates is much quicker than you pressing the FPS cap toggle. Rapid flicker.

If I want to use 240hz with HDR but not enable DSC, does the monitor use 8bit+dithering in place of 10bit native?

Yep. So far I wasn't able to see any difference between 10-bit with DSC and 8-bit without DSC.

Visiting this post back again but man, I have to say this monitor kinda disappointed me. The black crush in SDR mode has you choosing between lowering your refresh rate to 120 (essentially halving it) and losing out on the vivid colours from Racing mode. The HDR mode looks insanely washed out and hazy as soon as you enable it, I messed around with it for hours at this point and what I can guarantee you is that its not a saturation issue, but rather a Gamma issue. This monitor looks brighter in SDR than it does in HDR, and ASUS has still not pushed a firmware update that addresses this problem after a year. Setting gamma to 1.20 in control panel somewhat alleviates this, but this is not what I'd expect a premium OLED monitor to perform out of the box, and leave user with so much fine tuning.
