Probably by editing your GRUB config or whatever bootloader you’re using.
Here is the EDID
Thanks, that should be enough I’ll have a look when I’m free. Also something like get-edid > monitor.bin would probably be easier for me though.
Edit: I’ve had a look, I can’t see any issues. Both checksums validate correctly and it advertises audio support. As you’ve probably seen in edid-decode, I’d expect it to show as ‘SONY TV’ (or at least for KDE ‘Sony SONY TV’ I believe).
