Summary: The unit is very finicky. It plays OK the DVDs, but has hard time detecting the connection to the computer. It breaks down, I had to send for replacement 2 times. Now it is out of warranty and it broke down again. The want me to pay $110 just to look at it. They charge $100/hour for their labor and parts are not cheap (e.g. lamp cost over $300). My recommendation: Stay away from Optoma. I think a big screen TV / monitor, is much better.
