What projector only comes with vertical keystone!? Not everyone can use the projector straight on with the screen. Mine has to sit off center just a smidge. No options to adjust the horizontal keystone. Only vertical. Super annoying.

Purchased the projector HD28HDR in June 2021 and the HDMI system already failed in April - Cant get technical support. I have written messages and try to contact them by phone with no luck. Its very frustrating.

projector is great. awesome picture. hard to see during day hours but at night it is awesome

I bought this unit to replace the HD 26 that I bought in 2016. That was a very good projector I had purchased a new bulb for it and very recently the color went out on it and it was only in black-and-white. The funny thing is when I was reading the reviews for this one the remote control only had 3 1/2 stars but on the HD 26 it has five stars after unboxing I compared the two and they are the exact same. I haven’t heard mounted to the ceiling in the place of where the HD 26 was about 15 feet from the screen I am at the max and there is no adjustment for focus. Where the HD 26 had a zoom in and zoom out as well as focus and fine-tune

Great projector. Using it for a family media room and it is perfect!

The only negative is lack of audio. Either audio system or headset fixes the trick...good for on the go and perfect for gaming.

I bought this product last December, and I have been using it in a daily basis. Its been 6 months and the project broke down. Two red lights blinking, and the project doesnt work anymore. I bought from amazon US and it shipped to me to Saudi Arabia. I tried to contact optpma but they werent helpful at all. I need help. Im tired of trying but nobody answers back.

worked great for 18 months, then pixels started appearing and thats when I found out its only under warranty. my last optoma lasted 5 years with no problem, this one 18 months....Ill be trying another company after this too bad great product while it worked

Picture quality is extremely clear, but the speakers are HORRENDOUS comparative to any TV. You will absolutely need an external speaker, which will be especially challenging if youre projecting from the ceiling as you wont be able to connect a WiFi speaker. I think anyone would expect much better speaker quality for a $700 projector.

It wont shut off, and stay off, it will turn on at ant time. It keeps turning back on. The remote is very unresponsive.
