Epson Home Cinema 8500UB Projector – Performance

Epson Home Cinema 8500UB Brightness

The Home Cinema 8500UB is about average brightness in its best movie watching mode. It is, however, probably produces the brightest image with good color, of any sub-$5000 projector. It’s not the absolute brightest, as, for example the BenQ W6000 can muster up a few more lumens, but to get respectable color out of the W6000, it ends up definitely not as brlght as the Epson, with comparable color performance.

We do our measurements at the mid-point of the zoom lens’es range. The projector will measure brighter with the lens in wide angle (projector closest to the screen), and dimmer when at full telephoto. Most people shelf mounting have their lenses set somewhere between mid-point and full telephoto.

First, here is a list of each mode (at factory default), showing lumen measurement and the color temperature of white (100 IRE). The mode names listed below are first for the Pro Cinema 9500UB then the 8500UB after the slash mark. Here are the equivalent names on the Home Cinema 8500UB. The bold modes below are the ones we worked with and calibrated:

Lumen Output and Color Temp at 100 IRE, Lamp mode on Normal lens at mid-zoom:

Vivid / Dynamic = 1316 @ 6365
Cinema Day / LivingRoom = 1175 @ 6833K
THX / THX = 503 @ 6505K
Cinema Night / Theater Black = 470 @ 8111K
HD / Theater Black 1 = 478 @ 6779K
Silverscreen / Theater Black 2 = 424 @ 5391K
x.v.Color / x.v.Color = 484 @ 6728K

Of note: Silverscreen / Theater Black 2 mode is optimized for black and white movies. All modes by Vivid / Dynamic and Cinema Day / Livingroom utilize an additional color filter to optimize color. This is why the Epson’s brightness jumps so much more than other projectors, when going from a “best” to “brightest” mode. With most projectors, brightest mode is 15% to 75% more lumens than “best”, with the Epson it’s almost 3 times as bright!

Pre-calibration we measured these color temperatures (target is 6500K) over the grayscale range. Overall a little warm, but very good for an out of the box mode: 30 IRE – 6304K 50 IRE – 6354K 80 IRE – 6403K 100 IRE – 6505K Post calibration the numbers were even better, with the projector staying within 100K across the range from 20 IRE to 100 IRE. And, overall, almost perfectly averaged at 6500K

When it comes to bright modes, we measured (after a “quick-calibration”) 1168 lumens in Livingroom mode (8500UB) / Cinema Day mode (9500UB), compared to 1309 in Dynamic / Vivid. The lower powered mode did have a bit better color and a more saturated look, but even the brightest mode looked pretty good.

Those numbers were measured by Mike after he did the “quick-cal”. In addition though, since he calibrated it, I tweaked the Dynamic / Vivid mode by eye, adding some contrast (at the cost of crushing a little highlight detail), and minor increase to saturation, and a bit of green

My attempt did not raise the lumens by any significant amount – at most 10 lumens), but did allow for an overall brighter looking image for my sports viewing, by raising up the brightness of of the grayscale in lower ranges. In other words, I was able to end up with the same lumens, but an image easier to watch when a lot of ambient light is present, with just a bit of crushing of the near white objects.

Epson Home Cinema 8500UB Sharpness

I expected the Home Cinema 8500UB to be the same level of sharpness as the older 6500UB. For the most part I was correct. On the first page, I discussed Epson’s new feature – Super-resolution. There’s no doubt it is an interesting sharpening filter. It seems to work better than the usual edge sharpening, although it’s definitely doing some of that. Basically, ir uses color separation and edge sharpening, then to test its ability to do that without distortion, it reinserts the softness back in, and compares to the original. If it isn’t successful, it recognizes that the sharpening isn’t accurate, and it adjusts.

Overall, I found that while it does add a little noise to the image, it does improve the sharpness. I really like it for watching those great HD channels like Discovery, Blu-ray discs like Universe and Planet Earth, and anything else that’s well produced. On movies, I also consider it acceptable, but I’ll generally be a little more reluctant to use it. After all, film based content is softer than digital content, and that minimizes the difference in perceived sharpness between projectors.

So far, I’ve used it quite a bit. It’s one of those nice extra goodies. It’s there when you want it, and has to be considered a plus, especially on digital content. When viewing the Epson with Super-Resolution on, side by side with the BenQ, which I consider especaillys sharp, it seemed to cut the difference in sharpness to less than half.
