You could do but you'll find the specs are down on a TV than a monitor. IE those 30" Monitors should do 1900x1200 resolution. A full hd tv will do umm something like 1400 x 1080. You might find the response time and the contrast ratio down a bit too.
A full HDTV will do 1920x1080, that's what full HD means.
But yeah, I've seen it done and it's not pretty. A 30" PC monitor usually has much higher resolution than a 30" TV - as noted, full HDTV is 1920x1080, the Dell 30" is 2560x1600 - *that's* why they cost so much more. The fewer pixels over the same area means the HDTV looks like shit when running a computer display, it's not smooth and crisp at all like the PC monitor is.
As a compromise, I'd suggest 2 x 27" PC monitors. You can do that for under a grand and only be slightly worse off in inches, but better off in resolution. If you really wanted more screen area, you could always add a 3rd later on.
