Bought it and loved it, until 5 months later (only 300 hours of use) the lamp goes out. They only offer a 90 day warranty on the lamp. Guessing how much a lamp is 200!!! Even after you buy the 200 dollar lamp, still only 90 day warranty. The next projector I buy will have a better warranty on lamp.

Easy to find at good price on web, easy to collect, well packaged, everything in the box that should be, connected up & worked perfectly immediately. Then tried to ceiling mount it.....the less said the better. The problems were with my ceiling, my drill, drill bit....

I was looking for a quieter replacement for my Optoma HD23. I originally bought the UHD40 as I also wanted to move to 4K however, the UHD40 made a persistent low frequency buzz. It turns out the the XPR technology that allows affordable 4K projectors to produce 4x 1080p images in 1/60 of a second...

Looks amazing

So this my second order for same projector, as first got return due to my mistake (wrong address on account). Second projector arrived next day in good packaging through royal mail 24 hours tracked.

VERY impressed with this projector, use it every day now and refuse to use anything else. Gaming surprised me as the input lag is non existent, and I'm pretty picky. I was worried that I'd regret this purchase but I assure you I do not, well worth the price.

"I chose this projector for my teenage daughter's room. It is a good price and feels sturdy and well built. The focus wheel is smooth and unlike other projector in its price range it is not noisy. The image is very sharp and it is also very good for gaming.

It is a very powerful projector only at night. If you have daylight or any sort of light coming in. it is not good as they claim.

The 3D is very clear! Bought this one to replace the first generation I had (damaged by water, nothing to do with the performance of the projector)

Pay a visit to the "Home Entertainment Projectors" section of Optoma's websit e, and you'll see that the company has no shortage of 720p and 1080p projectors targeted at this audience. What audience?
