Hi,
A - GENERAL
ASUS board: P4S533-MX, 3.06GHz, 1GB
Video: integrated, SiS 651 chipset.
Monitor:
Hitachi, CM715, 19in; 1600,1200; 30-95; 50-120
Run at,
1200x768 x 85Hz - perfect (and preferred) screen
1200x768 x 75Hz - smaller (shrunk) screen
OS's: Linux 2.6.8.1 with XFree86 v.4.4,
Win2K to SP4, WinXP to SP2
B - PROBLEM
In Windows - on any SiS651 drivers, the ASUS original (2.13),
SiS's 2.22 or their latest 3.62 - the monitor boots up on 75Hz (max).
However, if monitor is left powered off UNTIL the system is fully up,
the monitor/driver then powers on at 85Hz (with allowed refresh
rates as high as 100 and 120! ).
On Linux, with XFree86 4.4 SiS driver, the monitor is always perfect,
(1200x768 x 84Hz x 68.5K - as read off the screen setup).
For the record, in XF86Config, the ModeLine is "1024x768"
94.50 1024 1072 1168 1376 768 769 772 808 +hsync +vsync
C - QUESTION (and pleadings for HELP)
A possible coincidence, I started noticing the Windows problem only
at one point after I installed the XFree86 4.4 (and its SiS driver).
I have NOT established any direct link (cause/effect) between Linux driver
and Windows behavior of the monitor/driver, BUT
being at my wits end, I'm wondering
1. If it's possible that the Linux SiS driver has somehow "programmed"
the monitor to respond with a changed ID string and/or different
timings, etc. which could confuse the Windows driver startup-query.
2. If the above MAY have happened (under ANY circumstances, Linux
or not), whether there exists a way (utility, etc.) to "reset" the monitor
to its original values.
Thank you for your help,
-- Alex
