Re: Xorg 6.7/MSI nVidia 5500/Widescreen LCD problem

I can see why the 1680x1050 at 60 doesn't work because of 146.25 pclk
and the monitor caps at 135. But I don't understand why it is locked
onto 60Hz and thus preventing a 50Hz version from being selected.

As 1680x1050 was a really non-standard resolution at the time of X.org 6.7
I would try to manually add a modeline to your xorg.conf:

gtf 1680 1050 60 -x

# 1680x1050 @ 60.00 Hz (GTF) hsync: 65.22 kHz; pclk: 147.14 MHz Modeline
"1680x1050_60.00" 147.14 1680 1784 1968 2256 1050 1051 1054 1087
-HSync +Vsync

gtf 1680 1050 50 -x

# 1680x1050 @ 50.00 Hz (GTF) hsync: 54.05 kHz; pclk: 120.21 MHz Modeline
"1680x1050_50.00" 120.21 1680 1776 1952 2224 1050 1051 1054 1081
-HSync +Vsync


The program gtf is used to help you calculate modelines. A modeline is
added to the Monitor section of your xorg.conf, something like these
comments:

Section "Monitor"
....

# These two are equivalent

# ModeLine "1024x768i" 45 1024 1048 1208 1264 768 776 784 817 Interlace

# Mode "1024x768i"
# DotClock 45
# HTimings 1024 1048 1208 1264
# VTimings 768 776 784 817
# Flags "Interlace"
# EndMode

EndSection


And just an FYI, I was unable to get Windows XP with a FX 5200 and this
monitor to get past 1280x1024 also (and it didn't even provide 16:10
resolutions -- terrible!)

Maybe it would help to upgrade the nVidia drivers in XP?
