I am happy with the product until today. It is broken after 7-month use right after the product support.

does not work with all HDMI cables, projector throw is for crap my original location is back 13.8 ft, at this distance image is to big (no adjustment left to adjust)

Happy with this purchase

Using with a 120 screen 15 feet away. Flawless. Love it !

Best projector Ive ever owned!

There are some scratches on the lens. The shape of a video is funnel-shaped and cannot be rectangle-shaped. The Keystone correction cannot change funnel-shaped to rectangle-shaped. Keystone correction cannot make funnel-shaped to rectangle-shaped. The projected image is unbalanced.

Excellent projector!!

Weve used this for a month in a home theater setup with Mac Mini (for internet) and a DVD player. It projects on a large classroom-size screen in our living room. Audio is sent directly out of the Mac Mini to a state of the art sound system. The whole thing is rather impressive. But I digress. Optoma HD39HDR has nice, clear images and it never goes out of focus. The only thing Ive found to be a problem is that when you are projecting in 4/3 aspect ratio for DVD and then go back to the 16/9 for internet, the color is all messed up, being to red and too rich. People all look like theyve spent the night in a toaster oven. The remedy--just turn the projector off and after 10 seconds turn on again and it will go back to normal. I love the rather economical bulb which is supposed to last years. In the econ mode, which preserves bulb life, the brightness is just fine for our living room. Our previous Otoma projector lasted 10 years with c. 4-5 hours operation per day every day. I hope this one will be as good.

Prefect for gaming. Simple system, no UI Nor WiFi. Serve for what it does the best: gaming image for 1080@60fps.

I returned the item well within the return time window and it took much longer than usual for the return process.(Buyers beware!They charged quite a bit on the return.)The projector is decent but didnt work with my pioneer reciever. It is seriously picky on compatibility with hdmi cables.
