 Posted: Sat Feb 24, 2007 7:54 am Post subject: Twinview and different resolutions - at wits end |
 |
|
Hi,
I've been trying to get my TV connected to my Dell laptop (GeForce 7900S) using TwinView. My desktop resolution is at 1920x1200 and my TV is at 1024x768. The problem is no matter what I do I cannot seem to get the TV ton run at 1024x768 so the TV only displays a partial view of the screen.
The relevant section of my xorg.conf is:
| Code: |
Section "Monitor"
Identifier "Monitor0"
HorizSync 28.0 - 96.0
VertRefresh 50.0 - 75.0
EndSection
Section "Device"
Identifier "Card0"
Driver "nvidia"
VideoRam 262144

Option "TVOutFormat" "SVIDEO"
Option "TVOverScan" "0.6"

EndSection

I've been going back and forth with different configuration settings for hours now. Is there anything that I am missing? I am using KDE but do not yet have it compiled with xinerama support though from my understanding this shouldn't affect the screen resolution of the TV?

See if having twinview by itself sorts things out.
eg.
| Code: | Section "Device"
Identifier "Card0"
Driver "nvidia"
VendorName "nVidia Corporation"
BoardName "GeForce 7950 GT"
BusID "PCI:7:0:0"
Option "RenderAccel"
Option "HWcursor"
Option "CursorShadow"
Option "CursorShadowAlpha" "32"
Option "CursorShadowXOffset" "3"
Option "CursorShadowYOffset" "3"
# Option "TwinView" "1"
# Option "MetaModes" "1600x1200,1440x900; 1280x1024,1280x1024; 1280x1024; 1024x768,1024x768; 1024x768; 800x600,800x600; 800x600"
# Option "TwinViewOrientation" "RightOf"
# Option "SecondMonitorHorizSync" "UseEdidFreqs"
# Option "SecondMonitorVertRefresh" "UseEdidFreqs"
# Option "ConnectedMonitor" "DFP,DFP"
EndSection
Section "Screen"
Identifier "Screen0"
Device "Videocard0"
Monitor "Monitor0"
DefaultDepth 24
Option "TwinView" "1"
Option "metamodes" "DFP-0: nvidia-auto-select +0+0, DFP-1: nvidia-auto-select +1680+0"
SubSection "Display"
Depth 24
Modes "1680x1050" "1280x1024" "1024x768" "800x600" "640x480"

I've never heard of a TV that displays 1024x768... Are you sure your TV supports that resolution?

Building xinerama support into KDE and X seems to have solved the problem. Although not all applications are playing nicely with the second screen. VLC maximises to full screen on the first screen (DFP-0) and not the TV even after building in ximerama.
Video playback on the TV is also a little choppy using Kaffeine, mplayer and vlc (and any other media player I've tried). Is this normal? I'd be surprised if it had anything to do with my PC as it plays back video perfectly when using Windows and is relatively high spec.
