[     6.539] (--) NVIDIA(0): VIZ XVT323SV (DFP-1): 165.0 MHz maximum 
pixel clock
...
[     6.543] (WW) NVIDIA(GPU-0): The EDID for VIZ XVT323SV (DFP-1) 
contradicts itself: mode
[     6.543] (WW) NVIDIA(GPU-0):     "1920x1080" is specified in the 
EDID; however, the EDID's
[     6.543] (WW) NVIDIA(GPU-0):     valid VertRefresh range 
(50.000-77.000 Hz) would exclude
[     6.543] (WW) NVIDIA(GPU-0):     this mode's VertRefresh (24.0 Hz); 
ignoring VertRefresh
[     6.543] (WW) NVIDIA(GPU-0):     check for mode "1920x1080".

looks like the display can handle 50-75 Hz, which roughly matches a 
Pixel Clock of 165MHz at 1920x1080. 1920*1080*75=155.520.000Hz
