This is my second UST projector in 4 months. The first was the Optoma CinemaX P2. The Optoma was brought back due to the unreliability of the HDCP handshake, which resulted in snow and frame cycles. Samsung is a more compact device with a much better menu system. Switching on the Samsung takes a maximum of 10 seconds versus 1-2 minutes for the Optoma. The Optoma had better geometric correction than the Samsung, but the Samsung's overall picture quality and sharpness is superior, as is the overall Samsung menu system. I only gave it 2 stars because after a week of normal operation, the device now only turns on for about a minute before "System Error --- Due to a system error, the projector will turn off automatically after a moment (5). . sec)". I have tried several cycles and hard resets with no success. This unit will be returned and replaced with the same model and I will try again. Although Samsung is rated at 2200 lumens and Optoma at 3000 lumens, the Overall consistency Brightness was better on the Samsung and actually seemed noticeably brighter than the Optoma I hope the next module will not suffer from this system issue and hopefully just be an anomaly and not a more serious quality control issue.
