Just bought a projector for this fall's UCF football season and was able to get an 8 foot screen from a 9 foot viewing distance inside my spare bedroom. But wanting to be within a budget i bought a Wimius K1 which gives from any angle a 1080p 60hz image for under $300. In my Amazon research many people comments on the $500 and below projectors is that even though there is fan, the max is about 3 hours before it cuts out due overheating. Anyone else who has projector have this problem? Another problem in comments was brown spots developed from lens infraction from overheating, anyone have that happen?
