Digital Cinema*10487793K

* Digital Cinema and Cinema modes use Epson's Cinema filter to improve color (out to P3), but at the expense of about half the brightness when engaged compared to other modes.

These Epson projectors are impressively bright.  The very brightest mode - Dynamic has a slight greenish caste (far less than most projectors' brightest modes.)  Still over 3200 lumens is great, do you can put this projector in almost any room, as long as there's some basic lighting control, and a proper screen. Note, that the 3200+ is full wide angle on the zoom lens. But you get "just a few lumens less" with the lens set to mid-zoom.

Bright Cinema rocks for sports, etc. Color while not perfect, looks great on sports and most things - think, probably still more accurate than most LCD TVs. But don't be afraid of Dynamic (especially with some minor adjustments) if you need every last lumen for your upcoming Super Bowl party.

Natural tops out over 2200 lumens, but even calibrated, and with the lamp on medium bright, and lens on mid zoom, Natural provides 1553 lumens for your 1080p and other non 4K/HDR/P3 critical viewing. That's more than enough lumens for a 150" diagonal screen, technically almost enough for a 200" screen!

Digital Cinema for 4K/HDR/P3 is excellent. Color is both accurate -and offers a wider color space than almost all of the competition, aka better color, often a touch more natural (more colors to do a skin tone, or subtle graduations such as grays or in skies.)

But Digital Cinema offers up just a bit less than 1100 calibrated lumens when calibrated for 4K/HDR, with P3 color!  Now that's not a lot of lumens for HDR, I find that I watch most 4K/HDR content this way. Sometimes when a movie seems overly "dim" I do use the alternative we also served up:

That alternative is a 2nd calibration based on Natural, but with everything geared to 4K with HDR.  In that mode, the Epson can handle REC709 (which is still more than some DLP competitors can do), but can't reach P3. So, as stated elsewhere - you have two modes to choose - the absolute best, but not all that bright, or 2077 lumens calibrated (also mid-zoom, full lamp).

Nice to have choices (which I have also said repeatedly)!

Brightness and Color Temperature "Best mode"

For this review we have done things a bit differently.  Typically with 4K capable projectors we calibrate a "best" 1080p" mode, a "best 4K/HDR/P3" mode and a Brightest (1080) mode.

Because of the Epson's Cinema filter, which improves color (makes P3 possible when running 4K), at the cost of about 50% brightness, we have decided instead to do two 4K modes:

  • Best 4K HDR/P3 mode, using Digital Cinema (with Cinema filter)
  • Brightest 4K HDR/P3 mode, using Natural mode (no Cinema filter)
  • Best 1080p mode

In addition, we also recommend Bright Cinema for sports and most HDTV when you need more lumens. And as we have noted, Bright Cinema is cooler - color temp wise, which many (including myself) prefer for most sports viewing.

Pre-Cal Color Temp Readings for "Best 4K/HDR Mode" - Digital Cinema

IRE RangeColor Temp. (Kelvin)
100 IRE7850K
90 IRE7852K
80 IRE7848K
70 IRE7858K
60 IRE8301K
50 IRE8119K
40 IRE7833K
30 IRE7642K
20 IRE7882K
10 IRE10335K

As you can see from the table to the left, overall, Digital Cinema starts out - before any adjustment, as being very cool.  Definitely too cool, so let's just say to use this mode for movies, you want to definitely lower the overall color temp.

The goal is to have all the numbers (except the very low end - 10 IRE, as close as possible to 6500K.  As you can see, we're at least 1600K above that here.  Try our settings, or at the least go to the color temp settings and lower them.  Hint: 6500K!

Fortunately, Epson provides very good and well behaved calibration controls.  You'll find all the settings we came up with on our two calibration pages.

In the next table, (below), you are looking at the Digital Cinema settings after Eric calibrated the Home Cinema 4010.  Again, he Pro Cinema 4050 will behave identically (give or take variations from lamp to lamp).

Post Calibration: Color Temp Readings for "Best 4K/HDR Mode" - Digital Cinema

Gamma Measurement

You will find gamma setting info on our calibration pages. Suffice to say for non HDR content, gamma is very, good, and very adjustable.

For HDR content (EOTF for HDR content), you will normally choose between the HDR 1 and HDR 2 setting.  Or rather you will set the projector for Auto HDR Bright, or Auto HDR.  I find HDR 2 to be a little on the dim side. I recommend HDR1 and therefore using the Auto HDR Bright setting so that these Epson projectors can easily and automatically select the best Gamma or EOTF (HDR)

ECO-Mode: Affect on Brightness, Power Consumption

Power ModeLumensColor Temp. (Kelvin)
Full Power (Natural Mode, mid zoom)21486994K
Medium (mid-zoom)15536686K
ECO Mode (mid-zoom)13856730K

From any color mode, switching from full power (High) to Eco mode, results in a measured drop in lumen output of just over 35%!  Typically, a 25% o 35% drop is what we expect with most projectors.

These Epson projectors, however, have three power modes. There's also Medium power, in the middle. Medium mode, by comparison is about 28% less bright than High lamp, and almost 10% brighter than Eco.  As a result most folks should rely on Medium power except when max brightness is needed.

We calibrated our "Best" 4K/HDR/P3 mode at full power (High) lamp, however, because for HDR we wan all the lumens we can muster (all else being close to equal).

Lens Position: Affect on Brightness

Zoom DistanceLumens - Dynamic ModeColor Temp. (Kelvin)
Zoom out 65” Tall32186944K
Mid-zoom 48" Tall29946686K
Zoom in 31” Tall23226674K

In the case of this Epson projector, there's only a small drop in brightness (6%) going from full wide angle on the zoom, to mid-zoom, but a far larger drop to telephoto - but still only 25%.  That's really very good.  There are projectors with 2:1 type zooms, that see drops of over 30%.

In other words, if you have to mount this Epson projector as far back as possible, in your room - such as placing it on a high rear shelf, you aren't sacrificing a really significant amount of brightness - you lose less than going from full power to low power on the lamp.


Let's take a good look at sharpness (and detail), or rather what we perceive as sharpness.  As I've stated, all these projectors have lots of image processing, and especially true of all non-native 4K projectors when doing 4K content.  These Epsons are, of course pixel shifters, and Epson has had some pretty excellent algos (algorithms), which allows them to look at first glance to be every bit as sharp as more expensive native 4K projectors.  Still there's always a price to pay.

In our photo player above, There are a number of pairs of images - full screen photos from 4K movies, and then closeups of the same scene.  Of particular note, look at the two close-ups from Valerian - the general, and the large collar on the Mul woman.

Those pairs are followed by our close-up of one of the credits scenes (in the lab) from Ghostbusters 2016.  When comparing look at the gauges on the left, and the small labels, and switches, there's plenty of objects in those photos to compare. Remember once you have clicked to enlarge the images, you can still jump back and forth between any two for quick comparisons.

Overall, these Epsons do very well, but we've seen sharper, but only slightly, even from less expensive 4K UHD DLP projectors. It's just that sitting 15 feet back from any of the 4K capable projectors under $10K, you shouldn't see any real difference, rather contrast differences, and other things that might give you the impression of sharper or softer.

Just keep in mind when "worrying" about sharpness differences, that the difference say, between these Epson projectors and perhaps, the Optoma UHD65 (2716x1528x2), and the native 4K Sony (4192x2160), in what you perceive as sharpness, is going to be far less than the differences in handling HDR, or for that matter color accuracy.  While I favor going native 4K, price is a huge determining factor for most of us.

When reviewing both Epson's UBs and the older HC4000 and PC4040 that preceded these models, I said you could get extremely sharp on 4K, but that there's going to be a slight bit of hardness, say on closeups of faces, that a native 4K won't have.

I do believe the new pixel shifting hardware is making a difference, but of course, only a small one.  I have to agree with Epson.  The pixel shifting seems more precise in that things do look just a touch sharper/softer than Epsons using the older pixel shifting technology.

My next review is the $9999 HiSense 100" Laser TV (yes it's an ultra short throw projector), one that comes with a fixed 100" screen designed for rooms with more than a little ambient light (such as most living/family/bonus rooms and many "media" rooms.

I took this pair of images - same frame, with the Epson Home Cinema 4010/Pro Cinema 4050, and with the Hisense.

At first glance you will immediately notice that the HiSense seems sharper. I agree. Looking closely though - thus the close up view - and you can see that there are far more artifacts. You can see lightness around small type, too much contrast and edge sharpening.  This 4K UHD DLP HiSense, is definitely over sharpened, in fact for this image I reduced its sharpness setting to 2, below any of the default settings, and it still had more hardness than the Epson, even with my cranking up Epson's Image Enhancement setting to 4 (as high as I go, out of 5).  Mostly I use 2 or 3, but use 4 for my sports where I don't mind a little hardness.

Back to the Hisense comparison.  I chose this to illustrate my point about image processing.  If you go back and look at the Epson vs some other 4K UHDs in the Ghostbusters credits, you'll notice that they aren't as over processed as the Hisense, but look a touch sharper than the Epson but not as sharp as the Hisense.  (I sure hope that makes sense - art)

Bottom line on sharpness.  The Epsons can be beat by the 4K UHD DLPs and by native 4Ks, but with its very good image enhancement controls any slight softness is likely gone, in exchange for a touch of hardness.
