Epson Home Cinema 705HD - Performance

Posted on October 8, 2013 by Art Feierman

Epson Home Cinema 705HD Brightness

Since Epson markets the Home Cinema 705HD primarily as a family room type projector that can crossover as a portable business projector, you have to expect it's pretty bright, and that is exactly the case. Only the Panasonic PT-AX200U comes close to this Epson projector when comparing brightest modes (although the Epson Home Cinema 720 isn't that far behind).

In "best" mode - in this case Theatre mode, it is definitely the brightest of any 720p projector we've reviewed in recent years. In Theatre mode we measured a dazzling 1571 lumens, which is more than double the average brightness for "best" modes.

At its brightest - Dynamic Mode - the Home Cinema 705HD outputs a whopping 2132 lumens even besting the Panasonic's 1699 lumens. Of course, as with all home projectors, the picture quality is better in "best" mode than in "brightest". Post calibration, lumen output dropped a whole 2 lumens (well within the measuring accuracy of our equipment - in other words - no change).

Here is the list of Picture modes, with the measured brightness, and also the measured color temperature of white (100 IRE) For typical movie watching as well as TV/HDTV the ideal color temperature is 6500K:

Lumen Output and Color Temp at 100 IRE (mid zoom):
Dynamic 2132 @ 6674
Living Room 1895 @ 7261
Theater 1571 @ 705HD6
Game 1850 @ 7392

Since the zoom lens has very little range, there is very little (actually surprisingly little) brightness difference across the range of the zoom:

Zoom out (wide) 2148
Mid-zoom 2132
Zoom in (tele) 2120

See the Calibration page for more information, and the settings we came up with for the best performance after calibrating the HC705HD.

Bottom line: Outstanding brightness, matched by only a couple other projectors. And the least expensive of the very bright projectors. Brightness is perhaps the single most dominating attribute of the Home Cinema 705HD.

Epson Home Cinema 705HD Sharpness

Image sharpness is reasonably good for a 720p projector. That the pixel structure is slightly visible, especially on signage (i.e., stats and info overlayed on the game you are watching, or, text in movie credits). If you sit far enough back that will disappear, but the reality is, in the actual content, after a bit, you just don't notice it at all, anymore than you noticed the scan lines on your old conventional TV. This is typical of almost all 720p 3LCD home theater projectors. Some of the lower cost DLP based home theater projectors, however, definitely produce a sharper looking image. We're not talking "night and day" differences, but, you can buy alternatives that are a bit sharper.
