Review on 🎮 High-Performance Optoma True 4K UHD Gaming Projector: 240Hz, 4.2ms Input Lag, UHD35 by Aaron Clayton

I bought this to replace my 9 year old Optoma HD 33. It arrived and I tested it before installing it. The original image quality looks very good. The fan seemed a little noisy. Then I flipped it over to install and it made a loud grinding noise. It's a very sad sound when you've waited years to get a 4K projector. I think the fan is not properly installed in the device. He stopped after a minute. A message was displayed saying the fan is blocked and the unit needs to be returned for service and is now shutting down. I returned it for a refund. Easy return to Revane. I reinstalled my old block. I'm not sure if I'm ready to try again or wait for bug fixes or other suggestions. I want it to live up to my expectations.
