Summary: For the price you just can't go wrong! I have been using this for almost two years now and have not had one problem with it. I run it in my basement on eco mode and the picture looks good even with some lighting on, it doesn't have to be pitch black in the room.
Summary: I loved this projector until just 1 month out of warranty when the pixels started getting stuck. In the course of just 3 days 70% of the image is completely obscured by white or black pixels. It will cost nearly as much to repair as for a new projector, so it's going in the trash.
Summary: people say u need an expensive projector to play xbox games but i bought this for about 450 and its been great. no lag on any of my xbox360 games. the image looks great without blurring on heavy games like black ops2 and skyrim,forza,borderlands,AC3 all look great. mines currently a 130in diag.
Summary: I have had this projector since January 2012, have put about 110 hours on it so far. I am including the guide on how to run 3D from your computer onto this projector below. but first pros and cons.
Summary: product came in on time started up flawlessly! then it wouldn't come back on at all even waited a day to turn it on.. but some forums said just to blow it out with some pc air dusters now works excellent! THANKS!
Summary: Bought a factory refurbished MX511 about 2 weeks ago. It is very bright and works well even in a moderately lit room. I use it mostly for Xbox 360 and it looks great. I have it projecting a ~116" image and the quality is very good. Great projector with HDMI input.
