Custom Resolution Utility (CRU)

I have a Dell XPS 9310 with Intel Xe graphics, and I'm trying to connect an external display via HDMI at 4k 60Hz. Despite Intel Graphics Command Centre reporting 4k 60Hz as a valid mode, 60Hz is not present as an option for 4k. Adding 60Hz with CRU doesn't seem to work either - and CRU itself works, because I successfully added 75Hz for 1080p.

My initial thought was of course that there's something wrong with the dock, or the HDMI cable - however, the same screen works beautifully at 4k 60Hz under Ubuntu. Is there any way to fix it? I hear that an older version of Intel Graphics Command had an option to add custom refresh rates, but I can't seem to find it.

Adding a resolution that should already exist won't solve the problem. Does the dock support HDMI 2.0? What about connecting the monitor directly to the computer?

Dock is indeed dual HDMI 2.0, and allegedly supports 2x4k@60Hz. Connecting via USB-C to HDMI cable has the same result (didn't test on Ubuntu though). I just ordered a USB-C to DP cable to see if that works.

The Ubuntu thing working flawlessly throws me off though. It'd be easy to put blame on the hub, but clearly there's something else going on. I've also managed to add a few frequencies between 30 and 50Hz (at 4k) but those don't work at all.

The problem is the Intel graphics driver for Windows thinks the connection doesn't support HDMI 2.0 for some reason, while the Linux driver might not be doing the same checks. Is this a monitor or a TV? Some TVs have a setting that needs to be enabled for HDMI 2.0.

Nope, it's AOC U27P2. There doesn't seem to be any option on the OSD menu to change the HDMI version in use. I thought maybe disabling adaptive sync might help but it didn't.

Hi,
I'm struggling with my HP laptop with LG0490 eDP screen.
The screen was taken from DELL "donor" works ok with native 1920x1080 60.020 hz 6bits color but only with basic Microsoft display driver.
Laptop uses A10 APU and after installing proper adrenaline driver, laptop screen goes blank with backlit only. External monitor works OK.
I tried to override EDID with CRU copying detailed display resolution to extension block using all possible types and seems I succeeded using DisplayID 2.0. But apparently I decided to mess with Adrenaline (it is HP 655 ProBook so not for gaming anyway) to reinstall it with minimal settings and after reinstallation it does not work. I did DDU/AMD cleaning +reset-all.exe +creating EXE (I know it is for Intel but tried anyway) = all voodoo stuff including reinstalling driver via windows update + all above combinations. The strange thing is sometimes I'm able to make it work just using restart.exe then screen is OK but then disappears. Once it even survived next reboot but it is random. It is visible panel-driver issue plus AFAIK Dell was messing with EDID in panels made for them by LG/Phillips but anyway I hoped I could override it with CRU.
Can sb. help me understand what can be the issue apart from broken panel? :-(
It is IPS, 6bit color does not matter for me as it will be used for coding mainly.

Running restart.exe disables and enables the graphics driver, so for the few seconds the driver is disabled, it uses the basic display driver. If the EDID isn't correct, the AMD driver might be defaulting to a low resolution which the panel can't display, so try connecting the other monitor and make sure the laptop screen is set to the correct native resolution after adding it with CRU. If it's set to the correct resolution and still won't display anything, then it's probably a hardware problem.

Hi all, I've been messing around with my old desktop that has an Intel HD Graphics 2500 in it, i used the .exe method as it is the alternative method for older generation intel gpu's, but it seems that it sort of messed up some things (which is most likely my fault), i dont remember in what order these happened but after installing the EDID im pretty sure i got the option to pick a higher resolution than what my display's maximum resolution is, I also had some problems when playing VALORANT, where the game would have my monitor name as blank and i was unable to change the resolution of the game as it would just be stuck at custom. I'm currently using a random off-brand 1280x1024 TV as my monitor, eventually i just tried resetting CRU with the reset-all.exe and restarting my graphics driver, now i dont exactly remember if it happened exactly after i did that since i fiddled around a lot of settings, but my monitor became a generic non-PnP panel in device manager, so i looked up this thread and searched if any other person have had this problem which thankfully there was. And so i did the fix which was basically exporting an .inf file and installing it. which worked fine as now my monitor is recognized by device manager, but the higher resolution option than my display's maximum resolution and the valorant not recognizing my monitor's resolution still persists. Is there anything i could do to just factory reset my monitor/tv's EDID back before i used CRU? or maybe a custom EDID that i can use? I know this was probably caused by my negligence of not understanding it properly before using it but any help would be appreciated. Thank you if you read the whole thing and apologies if its too long.

And as expected, USB-C to Displayport works flawlessly at 4k@60Hz. Glad that it works, but disappointed that now I have a hub with a useless HDMI - had I known, I'd have bought one with DP.

Does anyone have any idea why Windows causes issues with the HDMI connection?
