As another data point I have a Panasonic TH-50PX77U 50" plasma running
as a digital billboard. It is connected by a 50' HDMI cable and the TV
does not send out a strong enough signal for the video card to receive
the EDID info. I am running the panel at 1280x720 and here are the
relevant sections of my xorg.conf (X.org 1.3.0, Ubuntu 7.10):
Section "Monitor"
Identifier "PANASONIC TH-50PX77U"
HorizSync 10.0 - 80.0
VertRefresh 29.0 - 85.0
ModeLine "1280x720" 74.2 1280 1390 1430 1648 720 725 732 752
+hsync +vsync
ModeLine "1366x768_60" 88.0 1366 1424 1704 1816 768 770 782 808
Option "DPMS"
EndSection
Section "Device"
Identifier "Generic Video Card"
Driver "nvidia"
Option "AddARGBVisuals" "True"
Option "AddARGBGLXVisuals" "True"
Option "NoLogo" "True"
Option "ConnectedMonitor" "DFP"
Option "UseEDID" "FALSE"
Option "ExactModeTimingsDVI" "1"
Option "ModeValidation" "DFP-0: AllowNon60HzDFPModes,
NoMaxPClkCheck, NoEdidMaxPClkCheck, AllowInterlacedModes,
NoMaxSizeCheck, NoVertRefreshCheck, NoHorizSyncCheck,
NoWidthAlignmentCheck, NoDFPNativeResolutionCheck, NoVirtualSizeCheck"
Option "FlatPanelProperties" "Scaling = native"
Option "IgnoreDisplayDevices" "TV, CRT"
Option "UseEDIDDpi" "0"
#BusID "PCI:0:5:0"
EndSection
Section "Screen"
Identifier "Default Screen"
Device "Generic Video Card"
Monitor "PANASONIC TH-50PX77U"
DefaultDepth 24
SubSection "Display"
Modes "1280x720_60" "1280x720"
EndSubSection
EndSection
The ModeValidation section is because the EDID info fails to pass over
the 50' HDMI cable.
Cheers,
James
