And does the connected display do anything when setting the "ContentType" drm
property to "Game"?
Does it automatically turn on/switch into "Game" mode?

What tool should be used to decode the EDID file?
If it's edid-decode, then would need to check first how to install it, as there
apparently was a recent change:

The GUI of the official Intel Graphics Command Center for MS Windows has an
option to adjust the content type:
*
https://www.intel.com/content/www/us/en/products/docs/graphics/graphics-command-center.html
The setting was previously called "IT Content":
*
https://www.intel.com/content/dam/support/us/en/images/graphics/29572_image1.jpg
Now the setting is called "Text Content":
*
https://www.intel.com/content/dam/support/us/en/images/graphics/87657_image1.png
The setting can be set to "On" or "Off". And it always seems to default to
"On".
When clicking the "Learn More" button on the setting, it states the following:
> "What is it?

> When enabled, your display will not apply any of its built-in algorithms

> Disable this to allow your display to choose automatic modes when gaming,
> watching movies, or viewing photos. If your display is capable, it will
> automatically select the correct viewing mode for the content and switches
> modes when a new content source is selected."
If the official GUI for MS Windows on hundreds of thousands of Intel computers
has such a setting, then why should such a setting not also be available on KDE
Plasma?
