The Optoma HD20 is $999, and is an amazingly good 1080p DLP projector for the price. Also very bright--I can use it in a room with quite a bit of light. The 1080p projectors tend to best the 720p in a variety of ways, not just resolution. But even for lower resolution sources you will get a smoother picture. Blu-ray looks absolutely as good or better than any picture I have ever seen in a theater.
Difference between 720p and 1080p projectors?
I've had an Optoma H79 projector for 5 years and it still works great, but I'm wondering how much video quality difference is there between it's 720p resolution and newer projectors offering 1080p. And is there a very noticable visual difference/improvement or essentially the same?
