Display oversize
 
The display on my screen is twice the normal size, and the right hand end is off the screen

you likely have a setting wrong, or the video driver is set up wrong. We need to know the following:

What distro are you using? (Ubuntu, Fedora, Mint...etc)

What desktop environment are you using? (Gnome, KDE, Xfce, LXDE, Unity...etc)

what type of Video card are you running? (intel, amd, nvidia)

what driver are you using? (if you know) (proprietary or open-source)

xrandr
 
if you could post the result of running this command here it would help a great deal..
Code:

# xrandr -q
but in the meantime you can look into xrandr which "is used to configure which display ports are enabled (e.g. LCD, VGA and DVI), and to configure display modes and properties":

http://www.thinkwiki.org/wiki/Xorg_RandR_1.2

https://www.google.com/search?q=xrandr+examples


usually running..
Code:

# xrandr --output YOUR_OUTPUT --auto
should find your best settings, you can find YOUR_OUTPUT by running the command with the -q parameter like the one above and it will list the options, eg. VGA1, LSVD1, HDMI1, HDMI2, etc

Code:

# xrandr -q
...and make sure you run those as root. (that's what the # means)

I ran xrandr -q with this result:

screen minimum 320x200
curenmt 1024x768
maximum 4096x4096
VGA1 connected 1024x768-0-0
(normal left inverted right y axis x axis
477mm x 268mm

1920 x 1080 60.0

1680 x 1050 60.0
1280 x 1024 75.0 60.0
1152 x 864 75.0
1024 x 768 75.1 60.0 *
800 x 600 75.0 60.3
640 x 480 75.00 80.0
720 x 400 70.1
After running that, the screen reverted to normal size.

but we still do not know many of the needed things
is this a desktop?
a laptop?
or a hand held tablet

what operating system ?
and it's version?

the hardware ?
is it using a 3d card ?
or a "chip" on the mobo ?

if a card
is it Nvidia? AMD ?
or if a chip is it a Intel 3d chip?
or a nvidia chip or an amd chip ?

and depending on nvidia or AMD what driver is being used ?
and did you install something different than the default driver ?

--auto
 
from your xrandr -q it looks like you are connecting through the machine's VGA1 port,
now try running xrandr with the output set and --auto flag
Code:

# xrandr --output VGA1 --auto
you could alternatively use the --mode flag and specify a resolution from the -q list:
Code:

# xrandr -q
screen minimum 320x200
curenmt 1024x768
maximum 4096x4096
VGA1 connected 1024x768-0-0
(normal left inverted right y axis x axis
477mm x 268mm

1920 x 1080 60.0

1680 x 1050 60.0
1280 x 1024 75.0 60.0
1152 x 864 75.0
1024 x 768 75.1 60.0 *
800 x 600 75.0 60.3
640 x 480 75.00 80.0
720 x 400 70.1
# xrandr --output VGA1 --mode 1280x1024

if this fails we need more information on your system,
look at the other posts and try to answer as many of those questions as possible, search for the words you are unfamiliar with

mind you some problems are beyond your control to fix.. for instance if you are using a television for a display stead a monitor then the resolution problem could just be a result of the way LCD tvs and LCD monitors differ in how they manage resolutions

Oversize display
 
This is an ASUS desktop running Vista with a KVM switch used to switch to a Dell desktop running Ubuntu 12.04 which share a LG Flatron .monitor W2243T 22 inches.
I do not know what video card the Dell has - how do I find out?
Is this helpful?
