Red Hat Bugzilla – Bug 450248
Xorg 1920x1080p display is displaced on HDMI screen
Last modified: 2008-07-15 13:06:30 EDT
Description of problem:
Using ASUS P5E-VM-HDMI motherboard with onboard G35 GMA chipset and HDMI
connection to Full-HD TV display in 1920x1080p, the TV has an exact-pixel-scan
mode so that no overscan is used, the whole of the xorg display is displaced to
the left by an estimated 16 to 20 pixels, so the left side is lost and a black
bar is displayed at right side.
I tried to tweak the modeline using xvidtune, but any attempt to shift the
display to the right gives the message
"Sorry you have selected a modeline that is not possible, or is not supported by
your hardware configuration"
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. connect HDMI to 1920x1080p TV
2. start xorg
Display is displaced to left
Display correctly fills entire screen, or at least xvidtune can be used to
correct the position.

Xorg startup log
The modeline detected by EDID is
Modeline "1920x1080" 148.50 1920 2448 2492 2640 1080 1084 1089 1125 +hsync +vsync
By manually adding another modeline, with the sync pulse shifted 43 pixels to
the left, I was able to shift the picture to the right, though xvidtune refused
to allow such a change to be made dynamically.
Modeline "tweak1080" 148.50 1920 2405 2449 2640 1080 1084 1089 1125 +hsync +vsync
The package xorg-x11-drv-i810-2.3.2-2.fc9.x86_64
which is currently in updates-testing repo fixes this.
Thanks for letting us know.
