BTT Pi v1.2 & BTT HDMI 7

General Discussion

Hello everyone. I ran into a problem. Installing on BTT Pi v1.2 CB1 OS v2.3.3 and I connect the BTT HDMI 7 screen, but I can’t adjust the screen resolution in any way. Settings in the file BoardEnv.txt prescribed (extraargs=video=HDMI-A-1:1024x600-24@60)
Everything is displayed correctly on the monitor of the station computer. I connected the laptop to BTT HDMI 7, the image is also normal.

I am using the BigTreeTech HDMI7 as a display for a Raspberry pi 5 with desktop (Not Klipper Screen). I was having an issue where the screen stayed black, and what I found is that the BigTreeTech documentation does not provide the right code to enter (it is missing the = sign between “hdmi_cvt” and “1024” (4th line). The correct code to add to the config.txt is:

# uncomment to force a specific HDMI mode (this will force VGA)
hdmi_group=2
hdmi_mode=87
hdmi_cvt=1024 600 60 6 0 0 0
# uncomment to force a HDMI mode rather than DVI. This can make audio work in
# DMT (computer monitor) modes
hdmi_drive=1# uncomment to force a specific HDMI mode (this will force VGA)
hdmi_group=2
hdmi_mode=87
hdmi_cvt 1024 600 60 6 0 0 0
# uncomment to force a HDMI mode rather than DVI. This can make audio work in
# DMT (computer monitor) modes
hdmi_drive=1

I hope this helps anyone having issues with this BTT HDMI 7 display.
