Epson ProCinema 6040UB
Home Theater Projector
Brightness. The Pro Cinema 6040UB is rated at 2500 lumens. The Dynamic mode on our test unit far exceeds the rating, coming in at 3509 lumens with the lamp on full power and the zoom lens set to its widest angle position. As is typical, Dynamic is biased toward green and not suitable for optimal video reproduction. However, it is not typical for the Dynamic mode to surpass the projector's lumen rating to this degree. What this means is that the Bright Cinema mode which IS reasonably well calibrated for video/film display, measures a remarkable 2413 lumens, or almost the full lumen rating of the projector. All of our lumen readings are as follows:
Zoom Lens Effect on Brightness. The 2.1x zoom range on the 6040 gives you excellent placement flexibility, however the lumen output of the projector is 33% less when the zoom is set at the telephoto end compared to the wide angle end. To maximize lumen output, place the projector as close as possible to the screen.
Low Lamp Modes. The 6040UB has two reduced power modes, Medium and Eco. Medium reduces light output by 23% compared to the High lamp mode, and Eco reduces it by 25%.
Brightness Uniformity. The measured uniformity was an outstanding 93% -- anything 90% and better is practically speaking close to perfectly even illumination as far as the human eye's ability to perceive it is concerned.
Input Lag. Input lag measures differently depending on options set. If you are running with 4K enhancement activated, the frame interpolation (FI) system is not available. In this instance we measure 28 ms in both the Fine and Fast modes. If 4K enhancement is turned off, frame interpolation becomes an option, and you can select either Off, Low, Normal, or High. In Fine mode with FI off, the lag is 29 ms. With FI set to Low, lag is 68 ms, and when set to either Normal or High, the lag is 104 ms. With 4K enhancement off and the Fast mode selected, FI is not an option, and input lag measures 29 ms.
Bottom line, the fastest input lag achievable is with 4K enhancement on and the speed option set to either Fine or Fast, which yields 28 ms.
Fan noise. In High power mode the fan noise is audible enough to draw your attention during quiet interludes in a movie if the projector is mounted directly behind the audience on a rear shelf. It is not loud, but it is moderate in pitch, soft and constant, and not as quiet as you'd like in a small theater space. If you put the projector into Eco or Medium, fan noise drops in both pitch and volume to relatively quiet. In this mode it is not likely to be noticed during quiet interludes in a movie unless you are sitting without about 5 feet of it. It is not as silent as we've seen in other high performance home theater projectors.
High Altitude mode is required at or above about 5000 feet elevation. Fan noise increases in this mode. Many users would want to use the eco mode or take steps to isolate the projector from the viewing space to curtail noise if it needs to be operated in high power mode.
