So far I haven't heard any reports of EDID overrides working with RX 7000-series GPUs.

The problem only affects RX 7000-series GPUs.

my computer is Casper Nirvana C650 i7 8550U
940mx and i dont use any external monitor

Laptops don't have scalers and can't display non-native resolutions without GPU scaling, but Intel doesn't seem to provide a way to add custom GPU-scaled resolutions with laptops.

Can anyone confirm it?

Thanks!

That is accurate. Still no support for custom EDID's on my 7900XT.

Hi. I've got a spare 65" 4k tv (3840 x 2160 px) that is slightly damaged in the bottom part of the screen only, and rather than dispose of it or sell it for peanuts, I want to use it as a desk monitor, so that only the top 1600 px or so is used by the operating system and the bottom pixels are unused (as screen damaged there). I have it sitting on a stand behind my desk and is already lowered so that only the top part of the telly is above desk height. I would like the windows taskbar to be at desk height which is 1600px from the top of the screen.
I found out about ToastyX on Google, but I have no advanced knowledge of graphics cards and the inner working of monitors etc., so I'm a bit nervous of bricking my monitor. Can ToastyX achieve what I need, and if so, how could I blank off the bottom x number of pixel rows off my screen? Any help would be much appreciated (via Patreon also).

Hello.

I recently discovered CRU and have been using it to create custom resolutions for myself. They've always worked within the normal range for me. I basically use the program to create native 60hz resolutions and then create a custom 77hz resolution through AMD Radeon Software (it's safer to do it that way in my head). I created many of them (1440x1080, 1600x1024, 1280x1080), all with 77hz (maximum my monitor supports, above that it has no video response). But recently I've preferred 1920x1080 since my game (Valorant) doesn't have in-game differences between 4:3 and 16:9 and I ended up finding it a problem. At 1920x1080 the maximum I can put is 73hz. I was curious and went to try to understand why. I read the whole document and understood that the reason for this is probably the "max pixel clock" which in my case is 170MHz (as in the image). But the doubt came to me, shouldn't my limit be 300MHz? I have an RX 570 (which has an HDMI 2.0b output) and an HDMI 2.0 cable as well. Shouldn't it have a higher pixel clock number? Or does this parameter depend on the monitor?

It's not needed anymore. What problem are you trying to solve?

sorry for quoting old post. my nvidia control panel only shows RGB and ypbcr 444. its missing 420.

i want to test importing that .dat file to force 420. but that file is no longer there.

Any HDMI 2.1 display could implement those features. ALLM has no purpose if the monitor already doesn't have lag, and fast Vactive has no purpose with VRR because VRR already scans at the fastest rate.

Thanks for the response Boss. So if I was going for absolute lowest lag not using vrr would it help with input lag even slightly?

BTW I'd love to interview you on the channel if you're open to it.

Dear experts,
maybe you can help me with my g-sync problem:

I use my new PC (7800X3D, ASUS B650e-f, MSI RTX 4090 Ventus, Win 11) with 3 identical LG OLED 4K/120Hz 48-inch TV screens (model C1 from 2021, with g-sync compatibility) and I want to have g-sync with all monitors of course.

G-sync works wonderfully on the HDMI output of the 4090 and HDMI 2.1 input of the monitor, in full 10-bit RGB, HDR.

However, g-sync is not recognized on the two screens that are connected to the DisplayPort output of the graphics card (with a monitor input also to HDMI 2.1).

Unfortunately, the "g-sync menu item" is missing in the Nvidia Control Panel and "Monitor Technology" does not appear under the global 3D settings. The monitors connected via DP work in "HDR RGB 10bit full" but with a FIXED 120Hz.

I am not sure whether its the cable: I use one with DP1.4 -> HDMI 2.1 specification, see amazon: AGFINEST DisplayPort 1.4 to HDMI 2.1 8K cable.

Or could I fix this with CRU changing something at my TV settings (What & How)?

Thanks for your help as I am lost.
