Review on WiMiUS 4K LED Video Projector: 200'' Display, 4D ±50° Keystone Correction, 50% Zoom - Ideal for Indoor and Outdoor Movies, TV Stick, PC, Smartphone Compatibility by Chris Hodges

I ended up having to return this projector. The description says it can be placed up to 6.5 meters or 21 feet from the screen, but it won't focus beyond 15 feet. My mount is 19ft from the screen so it can't work. We saw the F1 qualifier then half the film on a 15ft 120 inch screen and it's a decent projector, the colors were a bit off but I was able to get them right. Brightness was good, gamma was too high. and is not adjustable, and even at 120 inches the resolution seemed smaller than my 8 year old 1080p Optoma at 155 inches. We switched back to the Optima halfway through the film and there was a collective Ahhh! Help. If this is your first projector and you have a small room, this is probably a good option. Currently I have ordered lamp number 3 for Optoma.
