--- Comment #20 from sergey79 at gmail.com ---
I did more testing and this seem to be an issue with 12 BPC mode @4k
resolutions. If I set the "max bpc" with proptest to 8-bit - I get a signal. No
signal with any 12-bit 4k modes (including 24hz).

I want to test with 10-bit instead of 12 but I have no idea how enable the 10
bpc mode. If I limit max bpc with proptest to 10-bit - I get max 8-bit.
