Hey everyone, I have been spending days on this issue without resolve. The monitor works in Windows8 at 4k/60 but using the same timings in Debian turns the screen blanks without any errors reported in the xorg log.
Nvidia driver: 343.22 on Debian Jessie
Card: 980gtx with high-speed hdmi cable | Display: 4k/60hz compatible Sony xbr49x850b
The details of the issue is here:
EDID or the working Win8 timings for the display do not seem to fix the issue. My guess is that the drivers for linux do not precisely set the output. This display will not show an image unless the numbers are precisely correct. Thanks for the help!
