Hi. Thanks for the reply.

No, this was a real monitor that looked a yard wide, but is more like 25
to 30 inches. They have lots of HDTV types that look great with a movie
but horrible when connected to a computer. I two friends who found that
out.

But, what actually caught my eye was not just the size, but the absolutely
wonderfully sharp image of the desktop that was showing. It was at least
as good as my very good Samsung 19".

Looks like, from your and other's replies, that all I need is a good
Nvidia card and it ought to do the job. I plan to go back over this
weekend and see what they are using, but making sure that I have lots of
time to research it properly this time. Reconfiguring my XF86Config-4
file is no big deal, especially with LCD monitors that you can't blow by
experimenting.

16:9 monitors work fine with Linux. I am currently typing on a Xinerama
setup with an IBM P70 (stopgap 17" solution after my 20" 4:3 died) next
to a huge Sony W900 (24" widescreen CRT, capable of 1920x1200(a)60Hz or
1600x900(a)85Hz), both attached to a GeForce4Ti4200-8X AGP card.

Modelines were a bit of a pain, I can get the W900 working at
1600x900(a)85Hz under Windows XP, but so far have not been able to
convince Linux to do the same. Currently I'm running on 1280x1024(a)76Hz
on the 17" and 1600x1024(a)76Hz on the 24" widescreen. Gentoo Linux with
2.6.14 kernel and Xorg-x11-6.8.2-r4

Here's the relevant bits from my xorg.conf

Note that the 1600x900(a)85 setting does not work...

Just a comment but BenQ, Sceptre, and Westinghouse are all selling 37" HDTVs
using one of two Chinese 1920x1080 panels for about $1700. Friend of mine
has the Sceptre and it works very nicely as a monitor--he's running Windows
though so can't really comment on how it works with Linux.

Hello,

You've mention apple and dell 30" monitors.
As far as know Dell requires PCIe cards with dual dvi. Only thoses card
would suuport
the resolution. I wonder could there be AGP cards with dual dvi that would
support
the 2xxx x 16xx resolution. Or does it mean that in order to be able to run
the dell's 30" one will have to buy a new m/b that leans new CPU and offten
new memeory etc etc etc
Than k you

Yes, but AFAIK they are expensive "workstation" cards intended for CAD
applications, e.g. ATI FireGL X3-256, 3Dlabs Wildcat Realizm 200 or
nVidia Quadro FX 3000. A new motherboard + dual link capable PCIe card
is likely to be cheaper than one of those cards.
