Epson Home Cinema 5010 Projector Calibration and Settings
12/17/2011 - Art Feierman
For your convenience we repeat the Epson Home Cinema 5010's (click for specs) brightness and color temp measurements from the Performance page
Let's take a look at the numbers:
Epson Home Cinema 5010 Color Temperature
Before we provide our settings, let's see what we started out with: Pre calibration, these are the color temperatures over the grayscale range:
Here's a look at the preset modes, showing brightness and color temperature for white (100 IRE).
Lumen Output and Color Temp at 100 IRE:
Dynamic= 1819 @ 7111
Living Room= 1375 @ 7983
Natural= 635 @ 6969, 455 in Eco lamp mode (default)
Cinema= 635 @ 6924, 455 in Eco lamp mode (default)
There are two additional modes - 3D Dynamic and 3D Cinema We don't have a good way to determine actual brightness to one's eyes when watching 3D, so no numbers are presented.
Epson Home Cinema 5010 Basic Settings
In addition to calibrating Red Green and Blue for a correct grayscale balance (6500K), there are a number of other settings that come into play. Typically Contrast and Brightness (white balance and black balance), need to be done first. Color saturation and gamma also need adjustment. In the case of the Home Cinema 5010 projector, most of these default settings were fairly close to ideal, with only contrast altered more than slightly in most modes.
Settings for measurements (default values are in parenthesis):
|Contrast = (0)||-2||-1||-1||-1|
|Color Saturation= (0)||0||0||0||0|
|Color Temp (default)=||6500||6500||7500||6500|
|Auto Iris=||Off||High Speed||Off||Off|
Auto Iris is Off for all measurements.
All other settings at default (untouched)
Zoom at mid range and Lamp mode on Normal unless noted otherwise.
Epson Home Cinema 5010 Post Calibration Grayscale:
Color Temp over IRE Range (Post calibration): User
Calibrated color temps, 20 – 100 IRE:
Home Cinema 5010 Greyscale Calibration
Color Temp over IRE Range (Post calibration): User 1
20 IRE = 6528
30 IRE = 6495
40 IRE = 6481
50 IRE = 6626
60 IRE = 6611
70 IRE = 6547
80 IRE = 6525
90 IRE = 6540
100 IRE = 6513
Average gamma = 2.05
No problem calibrating the Home Cinema 5010 projector - the grayscale ends up a nice and tight, spanning less than a 150 degree range, averaging just above 6500K.
The gamma, however, meaured a bit low. Mike reports this is due to an unusual dip in the gamma in the brighter range. For the most part, this 2.05 gamma, looks generally more like 2.2 or 2.3 than a 2.05.
Epson is sending a second Home Cinema 5010, so Mike can see if the gamma issue, and Delta E issue discribed below, is repeatable.
Here are Mike's comments, regarding the gamma, calibration and CMS.
Mike Notes: Using a gamma setting less than 2.4 results in gamma being even lower. The 2.05 gamma is deceiving because of a huge drop in gamma at 90 IRE. That really shouldn’t happen and makes me wonder if there’s something out of whack in the electronics or the lamp. If you average the rest of the gamma readings, it’s at 2.15.
Look at the grayscale graph and Delta E graph. Calibration strives to achieve a Delta E of less than 3 for each step from 20-100 IRE. That’s not always possible at 20 or 100, but it’s usually close and no more than 5. Here we have a Delta E right around 1 for the entire range, but then jumping to over 10 at 100 IRE. Could be the same issue that causes the gamma dip.
As far as the color is concerned, the CMS that could be used to reduce the oversaturated green and bring magenta into line.
Home Cinema 5010 RGB Settings
Below are Mike's adjustments for his for the REC 709 and Dynamic modes. Again the goal of "best" is a great looking 6500K grayscale, and the goal of "brightest" is to improve a bright mode in terms of color accuracy, but without compromising brightness significantly.
Home Cinema 5010 Post Calibration settings:
|Cinema (on User 1)||Quick Cal of Dynamic (on User 2)|
|Offset||R = 10||R= 0|
|G = -2||G= 0|
|B = 1||B= 0|
|Gain||R = -2||R= 0|
|G = 6||G= -10|
|B = -5||B= 0|
Post Calibration changes:
Color Saturation: -10 -10
Tint: 4 0
Gamma: 2.4 2.4
Lumens at 100 IRE: 630 1660
Ok, that's all we have for you. try our Home Cinema 5010 settings out, if you like. We will update this page, if anything significant comes out of the second projector, when we get, and look at it. Mike will rerun the gamma, and possibly other measurements.
