Comme= nt # 12 on bug 10782= 3 from raxondmc@gmail= .com 
I've tried with a monitor I have with my 580x :

Here is the modeline your monitor has:=20

[ 49.626518] [drm:drm_mode_debug_printmodeline [drm]] Modeline 64:"168=
0x1050"
60 146250 1680 1784 1960 2240 1050 1053 1059 1089 0x48 0x6


Here is mine:=20

<div> [drm:drm_mode_debug_printmodeline [drm]] Modeline 68:"1680=
x1050" 60
146250 1680 1784 1960 2240 1050 1053 1059 1089 0x40 0x6

Now, the diff seems to be second last print on the lines. That said, my mon=
itor
is not 1680x1050 native, but it supports this mode.=20

Clocks seems to be the same, now i am wondering if it's the panel (NEC) in =
your
case that is picky or just Carrizo PLL's are not encoding at that modulated
clock.

I'll try to find a CZ and try it.

Cheers.
