I am trying to remove 4k TV resolutions from my LG Ultragear PC monitor but no matter what I do the settings don't want to apply. After going through all the steps and restarting, the TV resolutions still appear in NCP.

What model is the monitor? Run this and post the test.txt here: https://www.monitortests.com/EDID-test.zip

Model No. LG 34GS95QE

The monitor has TV mode and even though I don't have any device but my PC connected, certain games cause it to think I've connected a console and so it defaults to TV 4k 120hz and then causes some scaling issues when it goes back to native 1440p 240hz.

This needs to be reported to NVIDIA. Their driver seems to ignore EDID overrides when Display Stream Compression (DSC) is active. I see you tried both DisplayPort and HDMI. DisplayPort requires DSC for 3440x1440 @ 240 Hz. Technically DSC shouldn't be required for HDMI 2.1 at 48 Gbps, but for some reason it's active with this monitor. If the monitor has a way to turn off DSC, that might work around the problem.

Thanks Toasty. I'll get to reporting it. I checked my menus and no way to disable DSC for HDMI 2.1. I don't have this issue with DP 1.4 but I get very bad VRR flicker. I guess I'll settle with flicker for now bc the scaling issue makes games look blurry.

And yes, I tried modifying the VRR range but that setting doesn't stick either. Seems no matter what I attempt to change is ignored by Nvidia.

Hi, I have problem with one monitor (Eizo S2242W) that the resolution in Windows 11 is lower (1680x1050). Native resolution is 1920x1200. Problem is observed only when monitor is connected over docking station Dell WD19TB in Windows 11. Resolution in bios for that setup is correct.
I was trying to add additional standard resolution using CRU but didn't help.
Do you know where the problem is?

How many monitors do you have connected to the dock? What adapter are you using to connect the monitor to the dock?

For the test I had only one monitor connected.
Right now I'm using two monitors (second one is 4K monitor) with another laptop with Linux and everything is working correctly with the same docking station.

Eizo monitor is connected using DVI-DP cable.
The same problem is observed after connect monitor to the docking station using DVI-HDMI cable. Connecting directly to laptop using the same cable (DVI-HDMI) is ok.

What GPU do you have and how is the dock connected to the GPU? What is the pixel clock of the first detailed resolution?

GPU is Intel Iris Xe Graphics (i7-1365U). Connection is made via the Thunderbolt port.
I'm not sure about pixel clock. Some info:
