| Personal Experience |
| The projector's image is great when using HD content, but poor when using SD content. On normal DVDs you will notice a lot of dot crawl especially around opening titles. Try the HD-DVD "Happy Feet", the HD side plays perfect. The other side which is DVD quailty is full of artifacts in the image. You will notice this right away with the opening tiles and the earth. The earth has crisscross black lines across it. Then when the camera floats in on the penguin herd there is a ton of noise and artifacts. You can minimize this poor quality image by not feeding the projector a 480 progressive image. The 480i signal is a lot better, but still not great. The next thing is place the sharpness level of the projector to -3. This gets rid of more atrifacts and noise. This seems to be the best you can do with the image. This brings it up to a good image, but not great. I think a lot the problem is with the video scaler upconverting the 480 signal to 1080p. If all you are going to view is HD content this projector is great, but SD is only OK. Best tweak for gray scale and color temp seems to be Contrast -5 and brightest +7, color balance set to warm. This gets you to about 6700K. I'm trying to decide if I should keep my old Hitachi 720p projector because that had a great SD & HD image. I would then use the Hitachi for DVD content. |

| My first projector had to be returned because of what Mitsubishi thought was a bad video chip with all the artifacts I was seeing. Also green circles starting showing up on the image after about 15 hours of use. These were about 5" across on a 8' wide screen. One went away after 18 hours of use. Mitsubishi replaced it right away and were very helpfull, but couldn't explain the green circles appearing in the image. The second projector still had the same problem with artifacts on SD DVDs |
