Epson HC5040UB, PC6040UB Projector – Calibration & Settings


This page contents measurements and pre-post calibration settings and results. In addition there are several paragraphs of notes from Eric, our new ISF Certified calibrator.  This has been his first projector calibration for us, so naturally we thought we’d give him a challenge:  A projector with HDR and BT2020, P3, support, etc.  Challenging in that calibrating and working with HDR is new to basically – everyone!   As Eric explains, the manufacturers – both projector companies, and device makers like Blu-ray UHD player maker Samsung, are all scrambling to get it right.

This calibration was done using an early engineering sample of the 6040UB.  We believe that full production projectors – which are shipping as of early Sept 2016, will have improved color tables.  As a result we plan to revisit these projectors, bringing in a full production version, so we can update our review and provide revised settings due to changes made.  We will update any and all recommendations here, as needed.

Editor’s note:  Update 8/16/17:  (Previous updates removed)  OK, the production Home Cinema 5040UB loaner from Epson that I currently have mounted to my ceiling, as been freshly re-calibrated by Eric.  All the measurements and settings from this page from original pre-production 6040UB calibration we started with a year ago, remain in place.  The new settings are at the very end.

You may find interesting info in all those old measurements and charts.  The new calibration settings we have, and the measurements should be similar to the originals, but we’ve learned a whole lot about HDR, and BT.2020/P3 implementation in the last year (as has everyone).  At the time, we simply stated, that we were unable to really achieve what would call comparable quality results with HDR, to that of good old 1080p SDR, etc.  

I now have for you settings that we believe make the Epson HC5040UB or PC6040UB look great on standard and also 4K HDR, BT.2020 content.  To be fair, the tendency (vs SDR) is still that lower brightness areas can look a little dim relative to the brightest areas, when comparing with SDR, but far less so, and it now looks pretty great – certainly for a $2500ish projector.

So, the last section is just one happy media player (for you to scroll through with about 30 images.  These are a full set screen shots of settings our three calibrations – a “brightest mode” for non 4K content, a “best” mode for non 4K content, and a mode  for 4K with HDR, and all the trimmings.

Perfect? No, today’s projectors simply aren’t bright enough to fully implement HDR the way intended (nor are most 4K LCD TVs).  But HDR implementations are impressive, and superior to SDR, when the lack of brightness is effectively compensated for.  

Caveat:  I’m still not 100% happy with the “gamma” of the image / settings – some movies still come out too dim, including a lot of scenes on the Enterprise in Star Trek (4K version of course).  We had the Gamma setting on 0, so I’ve tried instead using 1, which lightens, but lightens upper ranges a bit too, so I didn’t care for that.  The very last slide provides an alternate custom gamma you can plug in, which I am still fiddling with, but that I’ve used on any movies where I get that too dim feeling.  Feedback is appreciated on that.  Update: I am now using a custom gamma with the 4K settings, instead of the default 0 setting.  It’s similar to the one in slide 31 in the media player belowRe, but I have reduced the second and third from the left points on the graph, each by 2.  Put that into your Saved memory for 4K, and you have what I’m using.  I will eventually replace that slide 31 with an updated one.  

Epson Pro Cinema 6040UB Calibration Presets notes

Eric’s notes:

Although the 6040UB has faux K (pixel shifting), this is nothing new in HT projectors, JVC has been doing this for a few years now and Epson has had it in their LS1000 laser projector, which started shipping early 2015.

A note about HDR (high dynamic range): HDR is a fast evolving technology that is rushing into the market with everyone playing a bit of catch-up. As a calibrator for example there is very little in the way of test patterns to truly evaluate how well HDR is working. Each projector manufacturer has implemented their own HDR10 tone mapping and gamut mapping algorithms so the standard is a bit of a moving target. I predict a lot of firmware updates from manufactures as they themselves learn and refine their approach to HDR.  The HT projector market has always had a bit of brightness wars between manufactures but now with HDR, (as with 3D) light output is even more important. 

My time with the early engineering sample 6040UB was limited but I did find a number of issues with it that I hope are ironed out before Epson ships them to market. I sent most of my time in Cinema & Bright Cinema modes.

We provided our findings to the Epson product team, regarding many of these items, which require just minor corrections (i.e. changing the default HDR mode to HDR1, not the HDR2 used in this sample). Short version:  There doesn’t seem to be anything on Eric’s list here “that needs fix’n”, that Epson can’t have updated before first shipments.  -art

First up 1080p content:

  • In Cinema mode with BT.709 content, the pre-production 6040UB only displays the larger P3 (digital cinema) color gamut whether you select Auto, BT.709 or BT.2020. By reducing the saturation levels (too near 0) I was able to calibrate the 100% saturation gamut down to BT.709 but if you look at the after gamut chart you can see the 20, 40 & 80% saturation levels are way off (under saturated). (note: no projector can display BT.2020 so they scale down to P3 which is still bit bigger than BT.709)
  • In Bright Cinema mode, BT.709 content was displayed correctly, and was improved by calibration.
  • Grayscale bias controls were a bit course making precise adjustments difficult
  • In Cinema Bright mode gamma was extremely bright. I set my target to 2.10 which I thought was reasonable for a bright mode. What you see in the gamma log charts is the gamma set to -1, going to -2 just lowered gamma a little but kept the extreme peak and only attaining a 1.83 average gamma. I tried the custom gamma controls but found them very frustrating. I own the 5030UB and the custom gamma is just as frustrating, maybe I just need some tips from Epson on how to use it. I was hoping to use Cinema Bright for a “Day” mode but now I would only use it for sports or news, any movie watching I think I might use Cinema with lamp on high instead.

4K (UHD) / HDR content:

  • When you feed the 6040UB 2160p/HDR and under Signal tab in the menu you have it set to Auto, the projector switches to HDR Mode 2. Problem is there are 4 HDR modes and mode 1 seems to be the closest to the EOTF (Electro-optical Transfer Function) aka gamma target, as you can see in the ETOF charts.
  • The 6040UB allows you to choose SDR even though it’s being fed HDR. I would think you should not be allowed to do this and should stay locked into a HDR mode while being fed an HDR signal similar to what it does when fed 3D.

    Last table “Bright Cinema Mode Custom color temp w/ 5 starting point” can’t be right. Can you check? Value ranges are completely off.


      Hi, just back from two weeks vacation. And off to CEDIA on Wednesday. Much to do. Epson has promised me a full production version to arrive shortly after CEDIA, so I plan to load Eric’s settings in there, and see what happens, and will report back on that. I normally don’t take a close look at our settings, just use them after our calibrator loads them into one of the memories.

      Are you talking about with HDR content? (just checking) – I’m in the midst of answering dozens of comments, having just returned. I know that for HDR I recall that I did significantly reduce the saturation. We’re still trying to get a handle on the whole HDR thing. I’ve talked to Epson, and Sony, we’re all figuring it out. Sony has invited Eric – our new calibrator, and me, to their facility to see what we can learn. -art

        Hi art. I was referring to the last CALIBRATION table. It shows for example Red Gain = 8. The defaults are 50 on these tables so 8 seems low. Or a typo! Same for the other values in the last table. Blue = -22 ?

        I actually tried these values and it looked completely off in terms of color. I wonder if what was meant here was ‘8 clicks above 50’ (=58). Etc.

        As per HDR, yes it’s really not looking good. Many at he forums have been testing. We find that bluray 709SDR looks much better than 2020HDR. More pop, more color, more brightness etc.


          Hi again V I’ll have to dig out the whole thread, when I answer these I only see the most recent posting, not any of the thread. Let’s table the color thought for a couple of weeks until I have this new 5040UB “singing”. -art


      Hi again. Our calibrator Eric will take a look at this ASAP. Thanks!

  • vespworks

    Art, I’ve been testing my 5040 for over 150 hours and there is something that is bothering me a lot. Can you check on this, or possibly ask Epson about this when you meet with them?

    I continue to be troubled by the motion handling of this projector under
    24p mode (Blurays, for example). What I see can be described as a
    STROBING effect of sorts. To be clear,
    I don’t see any significant judder, the pannings are smooth and not
    ‘jerky’ — however there is a strobing effect on very bright areas of
    the screen when there is panning or fast action, most especially
    pronounced on high contrasting areas of the screen.
    I don’t see anywhere near this degree of distraction on my older 1080p/24p capable Sanyo Z2000 (pretty much flawless motion handling).

    This is my first my first Epson projector… is
    the motion handling any different than the 5030? I don’t think I read
    any complaints in the past about the previous model.


      Hi Vespworks, I just got a production 5040UB back in a couple of days ago. So, I’m back in business. From what you are saying, you are seeing this with 1080p. Can you identify a particular scene – a minute or so, from a movie. You know which ones I use regularly, but I do have about 150+ Bluray discs, the largest number of them action or sci-fi. Let’s see if I can see what you are seeing. If not, then it could be your unit. Also – what blu-ray player? -art

  • Skin Flute Player.

    I I read on AVS that your calibrator had re done the settings on this projector. When will those be posted?


      He sure has, problem is, I’ve been traveling for biz (and some vacation). I hope to be working on setting up the two pages on my flight home tomorrow. Either way, I’ll try to have them up no later than Thursday evening. -art

      • Skin Flute Player.

        Any updates on this? Looking forward to what you guys came up with?

      • yogesh

        hi… any updates please? waiting for your settings


          Hi yogesh, they are all there, on the first Calibration page. It’s just a series of every screen shot needed, for three complete saved settings – a good “brightest mode” for non-4K content, a “best mode” for non-4K content, and a 4K mode for HDR/BT2020. But read about the change to gamma settings I mention on that page – there’s a screen shot of the custom gamma for the 4K mode, but I have since decided I like it better with less boost on the 2nd and 3rd right most points on the gamma graph. Just follow my comments there.

          And let me know what you think, please, especially compared to what you are currently using… (I’m primarily interested in the effectiveness of our 4K setup. thanks -art


            Again, all the old calibration images are still there – read the update near the top, then go to the very bottom where you will see dozens of screen shots. Enjoy! -art

          • Sandaboy s

            Thanks for the in depth write-up…but there is no slide 31…what are the gamma settings for the 4K/HDR preset? Thanks

          • AnonymousCoward826

            I just copied all your settings directly but I’m confused about one thing. You said that you had an alternate Gamma chart for 4K/HDR content instead of 0, but I don’t see that slide (31). In fact, there are only 30 slides and while there is a custom Gamma chart, it’s obviously for the BRITE setting. Help?

          • yogesh

            Thanks …but there is no slide 31…what are the gamma settings for the 4K/HDR preset?

          • DillThePill

            I just subscribed to your site and I can’t find the updated calibration settings for the 5040. I’ve looked through the entire review and don’t see the screen shots you mention. I can view the subscriber only page with advanced calibration settings.

            Can you post the URL?

          • DillThePill

            Can you please provide a URL for the screenshots? I don’t know why but I don’t see them anywhere in the review. I’m a subscriber.


            Hi Dill! We just moved content from our old site to the new one. Some of the more recently updated pages, (including the added slide show of menus with the new calibration info, did not transfer. Our webmaster is working on it. I expect it will be back up, complete, early next week, if not sooner.

            hang in there just a little longer! -art

          • DillThePill

            Hi Art. Is there anywhere else you could put up the images? I’m trying to get this projector dialed in and I paid for a subscription because I thought that would give me access to your calibration settings.

          • Todd

            New subscriber. Subscribed so I could use the calibrations you did with the production 5040UB as a starting point. I don’t see them either. Just the original ones done last year on the pre-production 6040UB. Any other way I can get that content? email? Starting setup of my new projector tonight. Thank you.

      • Puck Pauper

        Art, the calibration settings in the tables here are different from the ones on the slides at the end which are also different from the advanced calibration settings. Which set of calibration numbers are the most recent that i should be using? If the slides are the most recent, will you be publishing the actual gamma numbers?

    • yogesh

      hi… any updates please? waiting for your settings. appreciate. thanks

  • Ron Fink

    I am having some issues seeing the media slide number 31 that contains the UHD memory gamma settings. It seems to be missing. Can someone check and include that or add the settings to this thread? Thanks.

    • Ron Fink

      Thanks for making slide 31 available.

      I have one additional question. It’s not critical as I’ve adjusted on mine for now to compensate. But could you verify the RGBCYM settings for the ISF Dark Room Natural memory setting? There are a couple of them that seem pretty extreme compared to most other adjustments I’ve seen here. For example, the blue hue is almost maxed at 95 with a saturation of almost 80 and brightness down to 33. The Cyan has a similar but opposite extreme setting for it’s saturation and brightness (14 and 77). When comparing the two ISF 1080p presets you offered on my system, this ISF DARK RM preset has a very magenta looking tint to it when compared to ISF BRITE RM preset. I am just hoping that these extreme settings for the blue/cyan settings are the issue as the setting for the BRITE RM preset looked pretty good for color consistency. I’d just like to ask you to revisit the RGBCYM settings to ensure they are correct as shown.

      Thanks again. I really appreciate your efforts to provide a great foundation for the best settings for this projector.

      • Bob Weber

        Ron,did you ever get a reply to this? I see the same tinting particularly on silver objects (i.e. Raider’s helmets). Would you mind sharing your adjustments for compensation?

  • CinemaPete

    This is a question I have tried to get an answer from Epson on: Their website shows the 6040 as having ISF, where as the 5040 shows no ISF: I contacted Epson tech support and spent 45 minutes with them. They told me both projectors were the same, no difference with features or menu options, but the 6040 allowed ISF but the 5040 does not . OK, then there has to be something different about the 6040 vs the 5040 right? But they could not tell me what that difference was. I inspected both user manuals for each projector and neither of them, in particular the 6040 which has ISF, mentions ISF. It was only here in this thread that I found the answer. I filed a “complaint” with Epson to provide better information both on their website regarding ISF and the 6040UB and in particular, their user manual for the 6040 which says nothing about ISF calibration. So, the moral of this story is you can’t always depend on the Manufacturer to give you an answer unfortunately. Thanks for asking this question alex d and getting the answer from Projector Reviews.
