[SOLVED] Misaligned Monitor - Black Margins Along Top and Left Sides

I currently have a dual monitor setup using Xfce4. The resolutions and location of the screens is fine, but there's a slight problem: The left screen is 'shifted' down and right by a small margin. This means There are black bars along the top and left of the monitor, and the bottom / right of it is off screen.

Currently using an HD 4800 series card with the open source driver.

My .xinitrc file

#!/bin/sh
#
# ~/.xinitrc
#
# Executed by startx (run your window manager from here)

if [ -d /etc/X11/xinit/xinitrc.d ]; then
  for f in /etc/X11/xinit/xinitrc.d/*; do
    [ -x "$f" ] && . "$f"
  done
  unset f
fi

# exec gnome-session
# exec startkde
# exec startxfce4
# ...or the Window Manager of your choice


xrandr --newmode "1280x1024"  109.00  1280 1368 1496 1712  1024 1027 1034 1063 -hsync +vsync

#DVI-1 is on the left
#DVI-0 on the right

xrandr --addmode DVI-0 1280x1024
xrandr --addmode DVI-1 1280x1024

xrandr --output DVI-0 --mode 1280x1024
xrandr --output DVI-1 --mode 1280x1024

xrandr --output DVI-0 --right-of DVI-1

exec ck-launch-session dbus-launch --exit-with-session startxfce4

I've played around with both my monitor settings and xrandr commands, but I am unable to fix it. What am I missing?

Switch to dvi if you can. If you can't check the org log for edid errors, and do a calibration of your screen.

What is the output of `xrandr`?

Re: [SOLVED] Misaligned Monitor - Black Margins Along Top and Left Sides

Are you absolutely sure that DVI-1 supports a 1280x1024 mode? In your xinitrc, it looks like you're forcing the issue---but if it doesn't support that mode, then you're in trouble.

Can you get DVI-1 on 1280x1024 with another operating system/video driver?

Re: [SOLVED] Misaligned Monitor - Black Margins Along Top and Left Sides

I have never had an issue running that resolution on Window 7, Vista, or Ubuntu (10 and 11). :s

I booted into Windows today and saw the monitor problem persist, which is a first. Toyed with the monitor settings and it seems to have resolved itself, booting into Arch now to see if it carries over.

Edit: It did carry over. That's so weird....

I assume Windows used the proprietary driver, and I remember setting the resolutions via Catalyst in Ubuntu. This is, as far as I know, the first time I've tried using the open source driver. Maybe that's it?

Nonetheless, the issue seems to have resolved itself... for now. Thanks.

Re: [SOLVED] Misaligned Monitor - Black Margins Along Top and Left Sides

Next time you can start by pushing some buttons on the monitor itself - I have one labeled 'Auto' which nicely aligns the picture if it become shifted for some reason. If it doesn't work the first time, hit it again or go through the OSD menus and try to manually adjust horizontal and vertical position.
