Bug Description
Binary package hint: xserver-
The display resolution present on the digital output (DVI, HDMI, SDVO-B) is reduced by 1. E.g. doing
xrandr -s 1920x1200
results in an actual resolution of 1920x1199 sent to the display. This results in stretching of the screen image by the attached display and finally in a blurry display.
. This bug is NOT present if attaching the same display by means of the VGA connector
. This bug is NOT present using other operating systems (= not a bug of the HP w2408 TFT display)
. Any resolution reported by the EDID of the monitor will be reduced by 1: 1600x1199,1024x767, 1280x1023, 800x599, 640x479, ...

The allocation of the two pipes A/B in the X3100 (GM965) architecture is the same for SDVO-B/TMDS-1 and VGA namely:
(II) intel(0): Output configuration:
(II) intel(0): Pipe A is on
(II) intel(0): Display plane A is now enabled and connected to pipe A.
(II) intel(0): Pipe B is on
(II) intel(0): Display plane B is now enabled and connected to pipe B.
(II) intel(0): Output VGA is connected to pipe none
(II) intel(0): Output LVDS is connected to pipe B
(II) intel(0): Output TMDS-1 is connected to pipe A
Maybe requires reporting upstream.

This is a Ubuntu bug report I'm forwarding for the reporter:
