Epson Home Cinema 3800 4K PRO-UHD Projector Review
Measurements & Connections
Brightness. The brightest mode for the 3800 came close to the 3,000 lumen rating, at 2,912 ANSI lumens. Setting the 1.62x zoom lens to its widest angle setting yielded measured ANSI lumens for High, Medium, and ECO modes in each color mode as follows:
Epson Home Cinema 3800 ANSI Lumens
Zoom Lens Light Loss: 6%
Brightness Uniformity (Wide Zoom): 87%
Brightness Uniformity (Full Telephoto Zoom): 84%
Lowest Measured Input Lag (4K): 20.6 ms
Lowest Measured Input Lag (1080p): 28 - 28.5 ms.
Epson specs 16.7 ms as the input lag with the Fast setting and about twice that with the Fine setting. In our tests, however, none of Epson's suggestions for changing settings had any significant effect on the tested input lag. Epson is conducting further tests and we will update our comments as new information becomes available. As things stand, the measured results shown above are in line with other projectors we've tested in Epson's current product line and are relatively low among home theater projectors, though they fall short of the 16 ms threshold that the most competitive online gamers seek out.
Fan Noise. In ECO mode, rated at 24 dB, the 3800 is hard to hear even in quiet moments in a quiet room. The noise level in Medium, rated at 32 dB, is loud enough that some may find it annoying while others find it acceptable, particularly in a family room with ambient noise. In High mode, rated at 35 dB, the noise level is enough to easily notice from anywhere in a small to mid-size room. Most people will likely find it distracting even in a family room and may want to consider some form of acoustic isolation.
High Altitude mode, which Epson recommends using at 4,921 feet and above, is loud enough even in ECO mode to be noticeable, but not terribly distracting, even in quiet moments. For Medium and High modes combined with High Altitude, most people will likely want to consider some form of acoustic isolation.
