I have a 4K LG TV and I have my Max2Play system connected via HDMI – I’m having difficulty forcing 1080p resolution consistently.
I have tried forcing Max2Play HDMI screen configuration to 1920×1080 using the Raspberry plugin settings:
o HDMI-Resolution: HDMI-Resolution: 1920×1080 @ 60Hz
o HDMI-Mode: HDMI
o HDMI Force Hotplug: enabled
And discovered, this only works properly if I reboot my Max2Play system with my TV turned off or detached.
If I reboot my system while the TV is turned on, the XServer and subsequent Jivelite app always starts in 4K resolution. This causes jivelite to fill only a top 1/4 rectangle of the screen.
I’m guessing the XServer is using EDID to sense the available HDMI display resolution rather than forcing the selected resolution.
Is there a way around this that I am missing?
[I’ll also keep looking for a solution, and I’ll post back if I find anything.]

I think I found a solution.
I added the following parameter to /boot/config.txt
The XServer now starts up in 1920×1080 resolution.
Since the XServer appears to be overriding the „forced resolution“ selection due to EDID, perhaps your Dev Team should consider adding this as an option in the HDMI Settings for Display Resolution area.
Disable EDID (checkbox) Disable Extended Display Identification Data (use this in the event a forced resolution is not working)
