if I run "gtf 1600 1200 60 -v" the resulting modeline is: # 1600x1200 @ 60.00 Hz (GTF) hsync: 74.52 kHz; pclk: 160.96 MHz Modeline "1600x1200_60.00" 160.96 1600 1704 1880 ...

Modeline for my LCD, please take a look - don't want to kill my LCD...
# 1600x1200 @ 60.00 Hz (GTF) hsync: 74.52 kHz; pclk: 160.96 MHz
Modeline "1600x1200_60.00" 160.96 1600 1704 1880 2160 1200 1201 1204 1242 -HSync +Vsync
- what is the vertical frequency in there ? I think that it is the "160.96". My monitor is a Viewsonic 20 inch LCD using the DVI connection. When I look at its specs on the Viewsonic site the vertical refresh rate of 160.96 (assuming that this is what the number from the modeline is - the V refresh rate) is too high for my monitor and pretty much any LCD, I think.
Here is the way the Viewsonic site details the refresh range:
"VIDEO INPUT Analog RGB Analog (75 ohms, 0.7/1.0 Vp-p)
Digital DVI-D (TMDS, 100 ohms, or analog capable)
Frequency Fh: 30~92kHz, Fv: 50~85Hz
Sync H/V separated, composite, sync-on-green (TTL)"
Isn't that saying that the monitor should run somewhere in the range of 50 to 85 Hz for the Vertical refresh rate and not 160.96 ?!?!? The display looks good but I don't want to damage my monitor. I could use some advice, please.

its not possible to set VRefresh at 160MHz. its tooo much high....
