I'm not sure that's advisable.... but it 'should' be OK.
Caveat: Keith Packard is a brilliant programmer, but I don't think you
can expect a refund if you manage to screw a card or display ;-p

Yes - it's the basis of the correct parameters - best to determine
requirements and device capabilities. See further down this post.

Hence my "do not use" "example" :-)
NOTE: sending new emails using the same subject breaks the thread and
makes it difficult to re-read all the posts trying to get all the

What Debian release are you running?

Should be:-
# xrandr -q
(or # "xrandr -q --verbose")

^^ Do you use VGA out?
If so please provide monitor/display information.

Do you want 1440x900 resolution?

Are you happy with only 720x576 resolution on the TV-out?
1024x768 is possible.

You wanted 2048x1536 for panning - I'm not certain that's possible
without losing accelerated 3D and reduced colour depth. I also don't
know you card, so can't advise as to it's ability to do DVI and VGA and
TV simultaneously.
What do you get from:-
$ cvt -v 1440 900
$ cvt -v 1680 1050
$ cvt -v 2048 1536
# get-edid | parse-edid
You may need to install read-edid (for get-edid and parse-edid).
cvt is part of xserver-xorg-core.
When you post the missing information I should be able to give you the
xrandr parameters you need. If you are in a hurry - "man xrandr" and
"man X" are good places to find relevant information.
Cheers
