Thanks.
It would be appreciated, greatly, if you could use "Reply" to continue a
thread - saves searching through lots of posts in order to patch
together all the needed information.

OK. You must be mixing sources (hopefully with judicious pinning).

Note: ^ that "output" name is determined by the manufacturer of your
video card (another reason I didn't supply a working example -
insufficient information about your system).

Your CRT monitor was a different aspect ratio - less width, similar height.
Your current, default, resolution is 1440x900 - anything higher will
either require custom >100dpi font settings (or a telescope) in order to
read small fonts.
I'm assuming you know that a bigger screen means smaller fonts? Some
people find that counter-intuitive...
What fonts do you use and what DPI do you have set?
Do you have antialiasing and subpixel hinting enabled? If not, then
enable them.

xrandr is just reporting what resolutions are available for TV-out
connection - not whether what is connected is a television, or whether
TV is piped to that display (or from).
TV-out is just an analogue output designed originally for the old
analogue CRT type television sets (with S-video/SCART/VGA inputs)

I'll add it to the xrandr command.

Noted.
I'd suggest using the current default resolution (1440x900) and a
panning resolution of 1680x1050 (saves scaling problems)

Thankyou.
We have some identical displays - but not video cards, that information
gives me an idea what your card is capable of.
Brian has pointed a bug report that might be relevant. I believe the
scaling problem is still outstanding - but (with new mode creation)
panning is definitely not a problem with nouveau (I use it on my
netbooks). I don't know about Testing though (and can't test it this
weekend).
Which video driver are you using?
(eg. nouveau, debian nvidia, or, proprietary nvidia).
I'll test it tomorrow (when the weekend guests depart) and post the results.
Cheers
