The Epson PowerLite L400U Installation Laser Projector operators using 3LCD technology which means we can expect some pretty good color, and good color and fairly high brightness! This projector offers six pre-set color modes, and three brightness modes and an additional customizable brightness mode. In the following images, we’ll show you Dynamic Mode in Normal Brightness, Dynamic Mode in Extended Brightness (ECO Mode), Presentation Mode, Cinema Mode, sRGB Mode, DICOM SIM Mode, and Multi-Projection Mode.
All photos except the one specifically marked with “ECO” were taken in normal brightness. We did not take a photo of Dynamic Mode, or any other color mode for that matter, using the “Quiet” lamp setting – it appeared slightly brighter than Extended, but had zero effect on color. We’ll discuss brightness on the next page.

Dynamic Mode, the first color mode listed on the Color Mode sub-menu, is that obligatory, sickly green, “In Case of Emergency Only” nasty color mode that causes everything on screen to resemble the shade of my son’s face the last time he caught a stomach bug. Unless you are desperate for those extra lumens, choose a better color mode. Now, as greenish as Dynamic Mode is, it is certainly nowhere near the worst I’ve seen from other manufactures. Dynamic in Extended (ECO) brightness is a little more green, and quite a bit dimmer, but still adequate to fight its way through some fairly heavy ambient light.
Next up, we have Presentation Mode. It’s a little cool, but it works for graphs, texts, slides, etc – but I don’t think I would watch a documentary on it. Cinema Mode is next on our list – and I love it. Skin tones look good, it’s not too cool and it’s not too warm, you can see the differences in colors on those color wheels, including a difference in the reds – which is nice, because most projectors I have reviewed had yellows and reds that were indistinguishable between the two shades of each. This is something 3LCD projectors are known for – bright, accurate color! sRGB Mode is next, and isn’t bad, but it is a little warmer than Cinema Mode. It is intended for graphics applications, but could be a good all-around color mode if you prefer.
DICOM SIM is our second-to-last color mode, and really messes with color. That is to be expected, though, because it’s only supposed to be used for one thing, and one thing only: Medical Imaging. What exactly is DICOM SIM? It’s an acronym for Digital Imaging and Communication in Medicine. DICOM is standard used in medical imaging, such as X-Rays, CT scans and MRIs. DICOM Simulation offers an enhanced grayscale protocol for training and educational purposes. I went into detail back on the Special Features Page, with a few more examples of medical imaging – if you missed it, jump back over there and take a good luck – I think you’ll be impressed with the clarity.
The final color mode the L400U has to offer is Multi-Projection. Multi-Projection is a customizable color mode intended to be used when color matching, or calibrating, one projector to another when multiple projectors will be used to produce a large image. It’s not intended for any other purpose, and thus starts off with some very cool color which suffers in accuracy – but with some adjustment I’m sure it will be just fine.
