LCDs are fine. Normally in this price range the DLPs have better contrast. Operating a projector isn't much different than operating a TV.
I bet if you GF saw it , she'd have no problems learning how to operate it.
I've turned mine into a videophile! I think she's pickier than me now.
Once you live with a projector, going back to the puny TVs is a no go. TVs are good for daytime viewing, but that's about it.
You'll never look at another video game the same way. lol
