I can't specifically recommend any TVs, but I can give you some general advice.
You probably already know that TVs are limited to a maximum resolution of 1920x1080. That's not very high by computer monitor standards, when you consider how large the screen is. But if you're sitting far away from them it shouldn't be a huge issue. Although text probably won't look great.
For specific panel technologies to look for, I'd highly recommend avoiding plasma. Plasma displays are succeptible to burn-in, which can happen when playing games because UI elements tend to be static.
Don't pay attention to the refresh rate advertised for TVs. To the best of my knowledge, there aren't any TVs out there that can actually accept anything higher than a 60Hz signal. They just mess with the signal by adding frames to reach their advertised refresh rate. If you are playing a game, this would cause nasty input lag and could possibly have other negative side effects. So I wouldn't pay much attention to advertised refresh rates (unless you're looking to use the TVs for 3D, anyway).
Likewise, don't pay attention to the dynamic contrast ratio values advertised with TVs. Dynamic contrast ratio isn't a useful measure of anything, as it means something different to each company. Static contrast ratio is more important, but almost always falls around 800-1000, so there isn't much difference between values on different TVs.
Make sure you know or can find out how much input lag the TV has. Most TVs have a lot of input lag, many have more than 100ms of input lag. Playing a game on that would be like playing with a ping of 100, i.e. not good. Some TVs do have a game mode or something similar that reduces input lag, and some just don't perform much image modification on signals from external sources. It varies widely, and companies don't advertise input lag values. You'll just have to read reviews before you buy, as many sites test this. In short, a TV that does less modification to the image will be better for gaming.
The panel technology used in the TV is also important, but I'm not positive they use all the same technologies as monitors. What type of panel is in a TV is another aspect that usually isn't advertised, so I don't really know enough about that to help you.
Finally, just a few things that are probably obvious. For a multi-display setup, you want to find TVs that have the thinnest edge (known as the bezel) possible. Thicker edges means a larger break in your display between monitors. I wouldn't advise getting two screens if you want to play FPS games on them, as your crosshair would be in the center, where there's a break in the screen. Either three screens or just one would work better. For racing games and other genres, though, two screens could work fine. With two screens, you'll need a PC capable of playing games at 3840x1080, but I assume you already have or are planning on building a capable system. With computer monitors, you can run games at lower than native resolutions to get better performance, but most TVs only accept input at their native resolution.
Hope that helps.
