Recently got RPI 4 and I tried booting it on 3 displays and none of them seem to show image(I tested it before buying and it was showing OS just fine on the display tested).
Since then I reinstalled Raspbian thinking it might have something to do with faulty setup but unfortunately it's the same. I've messed around with all kinds of settings such as hdmi_safe/hdmi_boost/hdmi_mode/dtoverlay with various results but still no OS. It either hangs up at console cursor blinking after showing RPI picture with executing services in the corner(dtoverlay=vc4-fkms-v3d) or just doesn't give any image at all with default dtoverlay.
I've been blaming the displays and probable solutions I could find using google(even in sticky post here) suggested generating edid but tvservice seems to be absent from recent versions of the OS and I couldn't find any other way of generating it.
I'm not sure what might help but here is additional information
I'm using micro hdmi to hdmi cabel that came with RPI that's connected to DVI-D adapter (first 2 displays were connected using hdmi with same results)
OS: Raspbian 64 bit
https://pastebin.com/0sXGgyPY xrandr --verbose result
I use ssh to run the commands
I have to use "export DISPLAY=:0.0" to run xrandr commands otherwise I get "Can't open display" errors.
If there's any more information needed I can provide please ask.
Appreciate the help
