Get an LCD, but don’t mount it up too high, the colors will be distorted.
Make sure it has a VGA port so you can connect it to your laptops.

You don’t need 120 Hz or features like that and most laptops can’t output 1080p over VGA, so a 720p TV will work just fine.

Go with a brand name – Sony, Samsung, etc.

I would recommend going through the company AVI-SPL. They can recommend the best solution for your company, while giving you a professional / commercial grade LCD or Plasma.

I would recommend the 50" NEC PlasmaSync 50XC10, excellent quality and size for presentations.

You totally need to be careful about getting caught up in hype over features that make watching TV or movies or such better. That’s not going to be an issue for you. But can add significant cost. So you can ditch those things and save a tone of money.

So ignore 120Hz/240Hz rates. Great for sports, action movies, and gaming. Way overkill for your needs (and adds a lot of $). Ignore LED LCD. Again great for other types of uses, but way overkill for you (and huge expense). But do go with LCD. I think that’s far better suited for the kind of corporate uses you talk about (a Plasma would be good if you were a TV production company only).

But I disagree with the other comment about 720p. I think you should go for 1080p to get full 1920×1080 resolution. Your LCD TV is just there to serve as a really large scale computer monitor really. So I would go with one with greater resolution incase you need it. If you want to tone down the resolution you can, but at least you have the option to do 1920×1080 if you want.

Definitely look out for VGA or DVI ports. That way its easy to hook up laptops to the TV. Most sets in that size range will have such, but just double check.

I would look to Samsung, Sony, Sharp, or LG at that size. I think you’ll get a good option from any of them. They are all top tier brands. As for some example options,

Samsung LN46B530 – 46" CCFL LCD 1080p 60Hz – http://www.amazon.com/Samsung-LN46B530-46-Inch-1080p-HDTV/dp/B001U3Y8OU/ref=sr_1_4?ie=UTF8&s=electronics&qid=1257205600&sr=8-4 – $1,074 Amazon

Sony KDL-46V5100 – 46" CCFL LCD 1080p 120Hz – http://www.amazon.com/Sony-BRAVIA-KDL-46V5100-46-Inch-1080p/dp/B001T9N0EO/ref=sr_1_1?ie=UTF8&s=electronics&qid=1257205829&sr=1-1 – $1,099 Amazon (normally I wouldn’t bother with the 120Hz, but Sony gives it to you here at a decent price)

Sharp Aquos LC46D65U – 46" CCFL LCD 1080p 60Hz – http://www.amazon.com/Sharp-Aquos-LC46D65U-46-Inch-1080p/dp/B001E8YQ1Q/ref=sr_1_1?ie=UTF8&s=electronics&qid=1257205920&sr=1-1 – $950 Amazon

All of those have VGA PC inputs. So you’d be in good shape. Any of those would serve you well. I kind of like the Sony option as it falls within a similar price range as the others but adds in the 120Hz. Again, while not necessary for your needs, it could be had for a decent price and so if you ended up showing something with some fast motion on it for some reason, it would be a bit better suited than the other choices.

Also use cnet.com to do your own review checks if you want.
