I am not sure what but I came home to realized the screen looks like this. I turned it off and on and it was still the same. Ironically if I took off my HDMI devices the actual projector screen looks stable. Ya! You are thinking it is your HDMI device (Chrome Cast and Amazon Fire TV). Nope! the devices are fine, they work fine on my LG TV and anywhere else and were working fine on this projector which is less than 20 days old until now. Not sure if anyone has experienced this. The projector takes quite a while to come on. Sometimes I think it is not even on then it shows up. Just takes its sweet time coming on but once it comes on it is bright enough such that any light in the room will hardly have any effect compared to my previous LG UST 1000ust projector. This projector throws some heat, you can probably use it as a heater if you like (jk). I would be happy with this but right now I am skeptical due to what I have seen with the screen. I ended up fixing it by resetting the projector back to factory default then it began working normally again. Less than 30 days of purchase is too early to do this so I am thinking of getting rid of it
