--- Comment #19 from Simon Farnsworth 2011-07-06 03:19:46 PDT ---
I'm using the preferred mode from the panel's EDID, which xrandr says is:
1920x1200 (0x54) 154.0MHz +HSync -VSync *current +preferred
h: width 1920 start 1968 end 2000 total 2080 skew 0 clock 74.0KHz
v: height 1200 start 1203 end 1209 total 1235 clock 60.0Hz
The panel is a Dell 2408WFP. This looks identical to the mode generated by cvt
-r 1920 1200 60:
# cvt -r 1920 1200 60
# 1920x1200 59.95 Hz (CVT 2.30MA-R) hsync: 74.04 kHz; pclk: 154.00 MHz
Modeline "1920x1200R" 154.00 1920 1968 2000 2080 1200 1203 1209 1235 +hsync
-vsync
so I'd guess that it is reduced blanking.
