No, I meant DVI inputs. The televisions take IN a DVI signal (they don't
put it out).
The seven-segment color wheel does not eliminate the rainbow effect.
However, only some people can actually see these or are bothered by them.
The main benefit of the seven segment wheel is better color. I believe the
darker scenes see the most dramatic improvement.
The HD3 and HD2+ chips do not increase resolution. They are still the same
fixed 1280x720 display that they have always been. They are however
improving contrast. The old HLN models were 1000:1. The new HD3 models are
1500:1. The HD2+ models will be 2500:1. There will be a DLP released by
Samsung in November using the new xHD3 chip from TI. That chip will be the
first DLP to provide 1920x1280 resolution, plus it will support 3000:1
contrast. This will come at a price premium though.
