Hey folks,
up until now, I've been using one of my screens through a kvm switch,
necessitating its use via analog video. Now, I'm ditching the kvm, and have
connected both monitors digitally. Here's where the problems are starting. The
right one just won't sync, and keeps blanking out.
Monitors are both Viewsonic vg2021m, and the card is a trusty nvidia GeForce GE
5200 with 128MB.
The monotors are set up as follows (xorg.conf):
Section "Monitor"
Identifier "Monitor0"
VendorName "Viewsonic"
ModelName "VG2021m"
HorizSync 30.0 - 82.0
VertRefresh 56.0 - 76.0
Modeline "1400x1050_60.00" 122.61 1400 1488 1640 1880 1050 1051 105
4 1087 -HSync +Vsync
#ModeLine "1400x1050_75.00" 155.8 1400 1496 1648 1896 1050 1051 1054 1
096 -hsync +vsync
Option "DPMS"
EndSection
You'll see I'm now trying to run them at 60Hz, rather than the 75Hz that
they're capable of.
The Screen section is set up as follows ( you can see a large number of options
that I've tried that is commented out! )
Section "Screen"
Identifier "Screen0"
Device "Device0"
Monitor "Monitor0"
DefaultDepth 24
Option "DPMS"
Option "TwinView" "1"
#Option "UseEDID" "FALSE"
#Option "MetaModes" "1400x1050,1400x1050; 1280x1024,1280x1024; 1400x

Option "MetaModes" "1400x1050,1400x1050"
#Option "RenderAccel"

Has detected the right monitor as being completely different to the left one!
Any suggestions as to how to calm down the right screen??
Cheers,
