thanks to all. I've tried 71.20 and 67.22 driver version. Both of them has enabled custom timings but they doesn't work very well. If I set 1920x1080 @24PsF the driver accept it but the resolution don't change.
I've tried with Powerstrip and I can get 1:1 mapping with 1368x768 but if I set these timings:
PowerStrip timing parameters:
Generic timing details for 1920x1080:
HFP=88 HSW=44 HBP=148 kHz=27 VFP=4 VSW=5 VBP=36 Hz=24
Linux modeline parameters:
"1920x1080" 59.400 1920 2008 2052 2200 1080 1084 1089 1125 +hsync +vsync
my HS-10 report out of range.
Vern, can you please show your Powerstrip (or NVidia custom timings) parameter for 1920x1080 @24PsF ?
Thanks a lot.
