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

Really? Show me the log please:

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.
