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:

Quote:Timing characteristics
Horizontal scan range.... 31-76kHz
Vertical scan range...... 59-61Hz
Video bandwidth.......... 160MHz
CVT standard............. Not supported
GTF standard............. Not supported
Additional descriptors... None
Preferred timing......... Yes
Native/preferred timing.. 1920x1200p at 60Hz (16:10)
Modeline............... "1920x1200" 154,000 1920 1968 2000 2080 1200 1203 1209 1235 +hsync -vsync

Standard timings supported
720 x 400p at 70Hz - IBM VGA
640 x 480p at 60Hz - IBM VGA
800 x 600p at 60Hz - VESA
1024 x 768p at 60Hz - VESA
1600 x 1200p at 60Hz - VESA STD
1280 x 1024p at 60Hz - VESA STD
1280 x 960p at 60Hz - VESA STD
1680 x 1050p at 60Hz - VESA STD

I think it's an Intel driver bug. I found several reports of people having issues with this dock and 1920x1200 on some systems with Intel GPUs. Likely it's limiting the pixel clock to around 150 MHz when it should be 165 MHz for single-link DVI. Someone mentioned using an active DisplayPort to DVI adapter will work around the problem.

Another laptop with Intel UHD Graphics 620 (i7-8650U) and Windows 11 connected to the same Dock is working correctly.

Then it's an Intel driver bug for sure. The bug doesn't affect all Intel GPUs. Using an active adapter will make it work like a DisplayPort display instead of DVI, which might work around the problem. Passive adapters will be considered DVI and the driver is not setting the correct limit. You need to report the issue to Intel.

Hi i need help! first, thanks a lot for this tool i use it about 3 years so much helpfull !
i play on TV ( TCL 55C635 4k ) with my big PC windows 10 RTX4090 and all works fine. but i upgrade my TV to a TCL 65X925 8k but on CRU i can't apply any change and by default it's not show me 8k resolution of the new TV, i think CRU show me settings of my old TV TCL ? if anyone kown how to solve this ? i want to create custom refresh rate like (40hz 45hz 35hz)

see screenshot if it work

sorry for my bad english i'm french

What is Beyond TV? That's not the TCL TV.

I don't know, it take this name when i connect my TCL 55C635 ( same with the new one ) maybe NVIDIA give this name ? I have only TCL or old TV Thomson, and very old Samsung monitor. ( Juste one screen connected at same Time )
