Cannot select resolution supported by monitor


My problem is similar to 


SUMMARY - 2560x1440 does not work

I have an Acer K272HUL capable of 2560x1440, as shown in Command Center.

1) It does not work at 2560x1440 on my Windows 11 laptop with Intel Iris Xe graphics.

2) It does work at 2560x1440 on a Windows 10 laptop with Intel HD4000 graphics.  (In that case, I had to add 2560x1440 as a custom resolution, but it works great.)


DETAIL 1 - shows as supported

The rest of this message is about the not-working Windows 11 / Iris Xe system.

Graphics Command Center shows that 2560x1440 is a supported mode:



DETAIL 2 - but is not an option

But it does not show up as a mode I can select:



DETAIL 3 - custom mode does not work

So I try adding it as a custom mode by clicking the "+" button, and I see it in the menu now:



And I go ahead and select it, and then select "Keep"


But the resolution of the monitor does not change.

And in fact, if I now exit GCC and start it again, it shows that it does not believe that the resolution has changed:



DETAIL 4 - Dual monitor setup

My internal laptop monitor is capable of only 1920x1080, but I have Windows 11 configured to display "Only on monitor 2", which is my WQHD monitor.

This same setup works fine with a different Acer monitor that also works at 2560x1440.




What can I do to get GCC to actually enable my desired graphics mode?
