Input: I have only had this for under a year, with usage limited to evening/night due to it only being just over 3000 Lumen and my place is has considerable light ambience. I installed blackout shades and was enjoying everything about this projector until I turned it on and has a huge yellow blob in the upper right screen area. After researching these blobs, I have learned it is the Blue LCD polarizer has probably overheated and burned the spot in place. I reached out to the Elephas team in November and they requested proof pictures. I sent the images (see my image uploads, the last two) and that was it. No more dialogue or conversation from these folks. I am going to have to go out and get another projector now, since this is just getting worse and more obtrusive when watching. Buyer beware.

Giant yellow spot appeared after only a few months
