CentOS - Jul 2020 - X11 issue on CentOS 8

I have files in /etc/X11/xorg.conf.d
rw-r--r--. 1 silentm silentm 311 Jul  9 13:25 00-keyboard.conf
-rw-r--r--. 1 silentm silentm 328 Jul  9 14:28 01-display.conf

This is my 01-display.conf
# This file goes into /etc/X11/xorg.conf.d

Section "Screen"
Identifier "Screen0"
Device     "Card0"
Monitor    "Monitor0"
SubSection "Display"
Viewport   0 0
Depth     24
Modes    "3840x2160" "1920x1080" "1600x1200"
"1440x900" "1368x768"
"1360x768" "1366x768" "1024x768"
"800x600" "640x480"
EndSubSection
EndSection

That looks fine. But the X log file shows its NOT being used. Why ?

Why is my xorg.conf.d files not being used ?

So what I thought was happening is not. Files are being read.

The issue is /var/log/messages shows the 3840x2160 resolution - but when I
goto the Settings->Display the highest resolution is 1920x1080.
This is native not a guest VM. Trying to fix the issue.

So it is loading my 01-driver.conf file and 01-display.conf file As Screen0
and "Intel Graphics" specify that.

But its kicking out the 3840x2160 mode? Why.

Any pointers?

I think you should find more information inside /var/log/Xorg.0.log.
What does it print about 3840x2160 modes? The same as in messages or
something like "Not using mode...."?
BTW: what is the video card you are using and the corresponding driver?
