This projector is perfect for my use : normal living room for watching movies or playing games. It's marketed as a conference room projector, but the color saturation from the 4 LEDs + DLP is very good and the color are pretty vivid (better than a PT-RZ570). Contrast is probably not the best, but the high brightness means it can be used in a normal living room even without the curtains closed : not optimal, but still usable. The projected image is about 120 inches in my setup on a standard quality screen. As it's a single chip DLP, there is still some rainbow effect (much less than a PT-RZ570), but it's really low. I think it's the closest one can get to a 3 chip DLP without the price tag. The manual says it can accept 1080p 120 hz which it does, but the only way I could actually display a 1080p 120 hz content was when I activated the sequencial frame 3d option with 2d content : the catch is that the image is half the brightness. Compared to a PT-RZ570, the white brightness seems lower, but the whites are on the same brightness level compared to the colors (which the PT-RZ570 can't do). It's also quieter than a PT-RZ570. Overall, it's an impressive projector that I don't regret buying. UPDATE 1 : from 5 stars to 1. Finally, with a DLP, the unability to use the 120 hz refresh rate is a real deal breaker for me. At 60 hz, everthing looks stuttery. With the slight motion blur of an LCD projector, it kind of blends every frame together so it's less obvious. I tried to get used to it, but I wasn't able to. Multiples cables were used and the projector information menu is really showing a 120 hz input. Through the lasts months, I exchanged emails with BenQ technical support to get this issue resolved. The whole process took some months and the return window on Amazon is long gone. The technical support finally took a picture of what they think is a working 120 hz display with the UFO blur buster test : the result is that the 120 fps and the 60 fps test are showing the exact same behaviour. Same spacing between the UFOs : same frame rate. Picture 1 is from me and is showing normal 1080p 120 hz mode (problematic one), picture 2 is from me and is showing 3D sequencial mode (where it can really do 120 hz display, but with less contrast and mediocre contrast) and picture 3 is from the technical support and is showing the supposed to be working 120hz (my camera shutter speed is not the same as their, but the results are similar). For BenQ, it's a working 120hz mode and they don't understand what to look for even if I tried to explain it to them. Their solution is to send the projector to them. Because they can't provide a tangible proof that their projector can do 120hz on their own side, how can I send the projector to them so they say it's working fine at the end ?? The thing is take, if it's working fine for them : they don't cover all the shipping fees!... I want to return the projector because it can't work the way it says in the user manual, but I can't though the normal Amazon process. I tried to write about this issue to the seller (BenQ INFTY Lab) though the Amazon platform, but it's been two week and they never answered. Now, my only option is either sell it used or take legal action against BenQ.
