Optoma EP728 review


Compact yet powerful DLP projector

Compact ; Well-made ; Good black levels ; Well-connected

Tricky to use ; Noisy pictures

Some slight operation woes aside, this is a capable projector and its design makes it an appealing package

size weight

being a mac user i have yet to find a projector that makes my presentations look as good as they could - this is almost there and the size is a plus

Optoma EP728 - DLP Projector - 2600 ANSI lumens - XGA (1024 x 768) - 4:3 - High Definition 720p


Compact and extremly easy to use compared with previous make (which was not an Optoma). The projected image and the high level of lumens for such a reasonable priced projector is outstanding.

The lens cover occasionally falls off.

Optoma EP728 - DLP Projector - 2600 ANSI lumens - XGA (1024 x 768) - 4:3 - High Definition 720p


I bought this projector for my wife and I haven't any experience of other projectors so can't compare. However I'm very pleased with this model.

The only (slight) criticism is that the focus ring is very sensitive

really happy with the projector, not very big and quite light. image is crisp and bright

the throw is quite short (should have my homework before) and it chucks out a lot of heat

Although early days, it's a reliable, easily portable projector with exceptional image quality. I'd recommend it.

Still waiting.....
