Dual Monitor Questions/Suggestions

I'm planning to buy 2 new monitors to replace my aging 17" monitor. It seems that pretty much all new monitors in the stores (besides online) are 16:9 screens, so I'm assuming I'll end up with a dual widescreen setup.

I'm trying to decide on the size and brand for the monitors. What are considered the better brands? I remember NEC's being really nice when I bought my last one, is that still so (I can't seem to find NEC anywhere besides online though)? How do all of the brands relate on quality, durability, features, etc? NEC, Samsung, Viewsonic, Asus, Acer, HP, Dell, etc, etc, etc!

Also, I primarily use the computer for general use, I run Ubuntu 9.04, and I have a graphics card with dual DVI outputs. I will also be doing a lot of programming on this computer which is one of the main reasons I want two separate screens instead of one giant one (having code on one screen and documentation on the other is the best thing ever). I do a little bit of movie watching and gaming as well. I'm leaning towards two 20" monitors, does that sound reasonable? Is it OK to get dual widescreens instead of 4:3 monitors? Are there certain features/specifications I should definitely look for when buying a monitor (I haven't bought a new monitor in a looooong time)?

Some of the screens are really shiny and I like that look a lot, but I think it would probably be a problem for glare? Is that right?

Thanks for any suggestions!

Note: Most threads and google searches seem to bring up really old discussions about these

Question Bios will only enable one or other of my video cards

I've upgraded my mother board and can no longer make two
displays work at once. I'm using the motherboard
built in video

system.board.product = 'DG31PR' (string)
system.board.serial = 'BTPR83401CYC' (string)
system.board.vendor = 'Intel Corporation' (string)

which is from Intel and a plugin PCI card (of which I've tried
several). The lspci listing for the cards is below.

The problem is that
1. if I disable the builtin graphics in the
BIOS then it disappears fully from lspci and Xorg generates
the correct for the PCI card and I run single
2. if I enable the builtin graphics then
as generated includes a dual head setup, but it will not
actually work: the PCI card is ignored with the lines

(==) MACH64(1): Depth 24, (--) framebuffer bpp 32
(==) MACH64(1): Using XAA acceleration architecture
(WW) MACH64: Mach64 in slot 4:6:0 could not be detected!
(II) UnloadModule: "mach64"

and the result is that the Intel head works fine and the
ATI one has no signal.

I think the problem is that the BIOS is disabling the
PCI graphics card when the Intel builtion option
is set and, amazingly, the BIOS has no option for
requesting both be live, as far as I can see.

This is a new motherboard with the latest BIOS, so
I cannot easily upgrade it to have better behaviour.

I feel the solution might be to do some setpci commands
to the PCI card so that the "[disabled]" attributes
are removed. I once wrote some PCI enabling code
that ran on a bare motherboard, so I do have the
full details of how to do this somewhere, but I think
there must be a command arg to /sbin/setpci that I can use?

Thanks for any suggestions.
