I have just installed a new monitor.

According to an accompanying brochure, Its specs are:
Horiz Frequency 30-72KHz
Vert Frequency 50-120Hz
Video bandwidth 110 MHz
Maximum Resolution and refresh rates:
1280x1024 up to 60Hz
1024x768 up to 85Hz
800x600 up to 85Hz
640x480 up to 85Hz

According to the manual supplied, the factory preset timings are:
1024x768 Vert Freq 85Hz  Horis Freq 68.68KHz
800x600   Vert Freq 85Hz  Horiz Freq 53.67KHz
640X480  Vert Freq 60Hz   Horiz Freq 31.47KHz
 =============================

On this basis I have used this modeline in my XF86Config:
# 1280x1024 @ 61 Hz, 64.2 kHz hsync
Modeline "1280x1024"  110    1280 1328 1512 1712  1024 1025 1028 1054

The screen looks OK at 1280x1024 - but are the settings I have used
"safe" for the monitor?
