Hi akatik
Also, take a look at config.txt on boot SD. By design, Raspberry should look here to set resolution. But sometimes it does not.
Configuring the config.txt resolved my issue, thank you.

Second display forced resolution not working

Hi,
I have a Raspberry pi 4 with two displays, (Both HDMI) i want to force the resolution to 1280x1024 on both as that is the size the application I'm running uses.
The configuration line
display = 1280x1024

Works fine on the first display, but the second
M2_display = 1280x1024

has no effect and the resolution goes to the standard 1920x1080.

Thanks in advance for any help
