Looking at the specs for most DLP projectors, I'm seeing 1024 X 768 resolution (1 chip DLPs) max. How is it possible to acheive a 720p resolution (1280 X 720) or above with this setup?


Thanks.

Troy,


TI has been producing a 1280x720 DMD device for over a year which has been used in several RP TVs. This chip has been tweeked to reduce light leakage and is now designed in several FP projectors.

The image is compressed to fit the native resolution. It just makes it possible to view 720P material. Some new DLP projector actually have a native 1280x720 resolution.

Is the compression visible to the naked eye? Does this introduce any unnecessary artifacts to the picture?


I've heard of the Mits RPTV that has the 1280 X 720 resolution (it got pretty good reviews in an issue of Home Theater mag).


Are there any DLP projectors that do 1920 X 1080? I know that they're cost would probably be astronomical.


Thanks.

If the scaler is quite good it might be dificult to see with normal video, with text from a pc you can normally tell straight away.

No. Though rumor has it that there is a 1920x1080 DMD (created for DARPA) in the TI-DLP technology demonstration center in Plano, Texas. I'll try to find the reference, if interested.
