UHD Graphics 750 cannot set 1920x1200 resolution

[Crewe55]

I have an Asus PRIME Z590-P (LGA1200) motherboard with 11th Gen Intel Core i5-11600K @ 3.90GHz CPU. My system is running under windows 11.  I wish to use a display with 1920x1200 resolution but this option is not available using either the on board graphics or GEFORCE GTX105i graphic card. Device manager identifies the display correctly but only 1920 by 1080 is show in the list of valid modes. Why is this?

Does the display support 1920x1200?  Have you asked nvidia the same question about their card?  Have you checked with Microsoft on their flagship OS?

The display runs @ 1920x1200 on a windows 10 system where that resolution can be selected. It is the same nvida card in both systems. Not sure where to contact Microsoft about the issue? Looking at the intel specification for the UHD Graphics it is not very helpful as it only specifies the maximum resolution available.

"Not sure where to contact Microsoft about the issue? "

How about the Windows 11 support forum?

Display native resolution 1920x1200 (16:10) is excellent for viewing of documents and programming.
I can advise you to click on the blank Desktop with right mouse button to open the context menu and select "Display Settings" in it, then sequentially follow the blue links "Advanced Display Settings", "Display Adapter Properties for Display 1" with the call of the standard Windows dialog of the properties of the video adapter together with the monitor and in it "List All Modes", in which you can see all the modes from where you can select the desired mode and press dialog's button "Apply".
On Windows 11, UHD Graphics 6xx on 4K Display VX3276-UHD are only 1920x1200 29Hz, 30Hz.
it is always recommended that you install the monitor driver from the monitor manufacturer's website

and in section "Supported Modes":

"1920 x 1200 (60p Hz)"

Ask answering dapxe about this mode accessibility.

Microsoft Corp. is committed to improving the Windows GUI experience and

at the best native resolution of the display, the dimensions of the elements in "Display", "Scale and layout"

"Change the size of text, apps and other items"

125&, 150% in Windows 10 and up to 350% in Windows 11

Therefore, you should strive for native screen resolution and use scaling.

But they occur here indirectly in the deciphered Raw EDID in the section "Standard Display Modes"

Standard Display Modes

In the EDID of your display, apparently, the resolution of 1920x1200 is described more specifically.

The EDID of the display itself is read via the display cable line and the display driver on the manufacturer's computer
which is always advisable to download and install, give complete information about the display for the correct interaction with it video card but there are also details:

"Obtaining Additional Monitor Target Modes"

or

https://docs.microsoft.com/en-us/troubleshoot/windows-client/shell-experience/incomplete-list-modes-in-duplicate-mode

"Windows 8: List All Modes in Advanced Display Settings in Control Panel displays incomplete list of modes when in Duplicate mode"

The .inf driver files for Intel Corp. video adapters also have a certain amount of DTD (Detailed Timing Descriptor) data.

Practically programming can use simple and unambiguous functions of the Windows API:
