Hi, I have the LG 34 ultrawide monitor which did do the 2560x1080 in Windows 10. On Windows 11, I was able to get this resolution to work for about 10 seconds before it began to fritz. So, I selected a different 21:9 resolution, i.e. 2432 x 1024. I did this because my computer is a Dell and comes with an NVIDIA Quadro P1000. I was able to download the latest drivers from NVIDIA and use NVIDIA Control Panel as follows:
Display > Change resolution
Click "Customize..." button
Click "Create Custom Resolution..."
- Select displays
LG Eletronics LG HDR WFHD
- Resolution settings:
Horizontal pixels: 2432
Vertlical lines: 1024
Refresh rate (Hz): 59
Color depth (bpp): 32
Scan type: Progressive
Timing:
Standard: CVT reduced blank
