I have an Optoma 1080p projector, as seen here http://www.optoma.ca/product_detail.asp?product_id=386. I have my satellite TV, wii and xbox 360 hooked up to it through a pioneer reciever through hdmi. The projector ran wonderfully and I havn't had any issues with it until now. On ever single thing I have plugged into it, I get little lines on certain parts of the screen, especially around writing. It is cieling mounted and has around 500 hours on it now. Maybe it's just some setting I did, I don't know. I've eliminated the reciever is doing it because of video conversion or anything else because I plugged the devices directly into the projector. I took some pictures of it on my xbox 360 dashboard: Pic 1, Pic 2, Pic 3, Pic 4, Pic 5.
