2D Image quality. The Epson 750HD is designed for casual home entertainment. Its brightest mode, far from being a greenish low-contrast mess as it is on most projectors, is actually quite watchable and would be appropriate for afternoon sports in a bright viewing room. Living Room mode makes the projector into a viable TV replacement, with a slight blue cast but excellent saturation and shadow detail. And Movie mode, with its near-6500K default calibration, is perfectly acceptable for evening movie watching.
HDMI 3D. The Epson 750HD is fully compatible with Blu-ray 3D movies. Normally, this is a feature we'd call "full HD 3D," but that doesn't seem right as the 750HD doesn't have full 1920x1080 resolution. It may be the first non-1080p projector we've seen that can handle Blu-ray 3D.
The 750HD uses RF-sync glasses, and one pair is included with the projector. This means there are no infrared signals flying around to interfere with your use of remote controls, as with IR sync. Nor are there light pulses interspersed in the image itself, as with DLP Link. It is also comparatively more difficult for RF sync to lose synchronization, as it is the only sync technology that does not require line of sight between glasses and screen.
As far as 3D performance is concerned, there is a loss of fine detail that comes from down-converting a 1080p source image to 1280x720, but 3D quality is otherwise excellent. The projector has lumens to spare, and using the default 3D Brightness option of "Low" did not produce any noticeable crosstalk. On the other hand, switching to "High" produced enough crosstalk that we would not recommend using it if you can avoid it.
Great color. Accurate color out of the box is important on inexpensive models since nobody will want to pay to have them calibrated. Fortunately the 750HD has excellent, well-saturated, accurate color in its factory defaults.
Color Light Output specifications are gaining traction these days. If a projector has color light output that approaches or matches its white light output, that projector tends to have a balanced image. Since the Epson 750HD is a three-panel LCD projector, its color light output matches its white light output. The result is a picture that appears natural and balanced, with colors that appear life-like and highlights that aren't overblown.
Auto iris. The 750HD's automatic iris gives it crossover potential. While the iris doesn't do much good when ambient light is present, it can give the picture an incrementally better black level once ambient light has been eliminated.
Quiet fan. For a 3,000 lumen projector, the Epson 750HD does not make a lot of noise. Its fan, while certainly noticeable during operation, is far from an overwhelming presence in the viewing room. Even the projector's small two-watt onboard speaker is more than enough to overpower the fan noise, and it doesn't need to be at maximum volume, either.
