Brightness - interesting:
Makes me wonder about the resolutions as well.
Monitor (make and model) comparisons just for the record.
I will run Firefox on my system and tinker with the brightness and/or contrast.
To get a lot of information about your video setting use Powershell command:
"Get-CimInstance -ClassName Win32_VideoController"
Here are my results (only edits were to redact SystemName):
