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?

Families spend lots of time at home and one of the most common family-time activities is watching a movie together, whether it's the latest release adults want to watch after the kids are in bed or a classic that parents want to share with their children.

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.

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.

Happy with purchase so far. Projector is bright and clear, works well in the space I have it in for gaming and media content.

One inevitable consequence of the UHD shake-up at the top of the home theatre projection market (think pricey 4K models from Sony and faux 4K alternatives from JVC and Epson), is that there are now serious bargains to be had lower down the ranks.

Compact and easy to set-up; Excellent Full HD performance; Vibrant colour fidelity; Suitable for movies and games

Doesn't do a deep black; Awful onboard audio system; Limited motion resolution

If you thought you had to budget big for a 1080p gaming and movie projector, think again. As 4K (and faux-4K) models take top billing, regular HD models are getting cheaper, and better, than ever. Optoma's single-chip DLP HD27 is a case in point.

Sharp; Rich colours; Bright enough for rooms with light; Great for movies and gaming

Limited black level; Poor built-in sound system; Can be noisy

Given the price point you have to accept that the materials used will be befitting of that budget.

Excellent colour accuracy to Rec.709; Good brightness and motion; Excellent 3D performance; Good image sharpness from the lens; Excellent build...

Some obvious rainbow effect with certain material; Mediocre black levels and shadow detail; Noisy even in Eco mode; No 3D glasses or emitter provided

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...

Picture keeps cutting out and searching for the connection. I've tried 2 hdmi cables (of different quality) and am using a lighnting bolt to hdmi adapter. i can't work out if it's the connection or the projector. when it works its great. when it doesn't its really annoying.
