Hello guys, before starts, sorry my very poor english…

i’ve a problem between my ubuntu, nvidia and screen.

My setups :

cpu : Intel i7 2600k
graphics card : Nvidia gtx 570
Screen : Samsung SMBX2250
1920x1080, 60hertz, HDMI

My Xorg.0 log spam me this error :

[  1784.468] (WW) NVIDIA(GPU-0): The EDID for Samsung SMBX2250 (DFP-1) contradicts itself: mode
[  1784.468] (WW) NVIDIA(GPU-0):     "720x576" is specified in the EDID; however, the EDID's
[  1784.468] (WW) NVIDIA(GPU-0):     valid VertRefresh range (56.000-75.000 Hz) would exclude
[  1784.468] (WW) NVIDIA(GPU-0):     this mode's VertRefresh (50.0 Hz); ignoring VertRefresh
[  1784.468] (WW) NVIDIA(GPU-0):     check for mode "720x576".

How to reproduce it : Run any program with gui or launch a game.

if you have solutions, i’m free !

This message is probably harmless. It just means that one part of the EDID says that the monitor can only handle modes with refresh rates between 56 Hz and 75 Hz, but another part says that a 50 Hz mode is supported. The driver assumes that if a specific timing is listed (in this case 50 Hz), that the monitor can handle it even if it’s outside of the range the monitor claims is the limit.

Are you seeing a problem with your screen, or just the messages in the log file?
