Epson Pro Cinema LS10500 Calibration Presets notes

Eric’s notes:

My overall impressions on the performance of the LS10500 are very good. I discovered a few niggling issues during calibration but nothing that really hindered its best performance. The LS10500 has 7 presets (Dynamic, Bright Cinema, Natural, Cinema, B&W Cinema, Digital Cinema & Adobe RGB) plus 2 for 3D.

I calibrated Cinema Mode for dark room viewing of HD (1080p) content. With Color Space set to Auto the projector produced a color gamut a little bigger than BT.709. After calibration, using the RGBCMY (CMS) controls the color gamut fell into a near perfect BT.709 across all luminance levels, resulting in very pleasing, natural colors.

The one area that bothered me a little was the fact that with the Contrast set to its default value of 0 the whites would clip quite a bit. This means you would lose detail in any content that’s close to peak white. There are 2 ways to fix this. Lower contrast to about -10 with Super White off or leave Contrast at 0 and turn on Super White, which is what I did.

Related to over driving the white level is the overly bright gamma curve even with Gamma set to -1. A brighter gamma curve does not make the peak whites any higher but the low to mid tones are brighter giving the impression of a brighter picture.

The default grayscale (white balance) in most of the modes including Cinema is a bit blue. I had to turn the Color Temp from 2 to -2 and Skin Tone from 2 to 0. This got me the closest to D65 before doing a 2 point RGB calibration. The end results are excellent with a DeltaE (error) less than 1.

For my bright room HD (1080p) calibration I first tried Bright Cinema Mode. Problem is after calibration it’s only a tiny bit brighter with a larger than BT.709 color gamut. The gamma is also excessively bright at an average of 1.57 and could only be brought down to 1.80 with my calibration (target 2.10).

I next tried Dynamic Mode and was able to achieve a 40% higher peak luminance than Cinema Mode (1068 vs 650). The downside was the color locking into larger P3 gamut used for 4K HDR. I was able to calibrate it down, closer to BT.709 and the gamma curve was better than Bright Cinema Mode at a calibrated average of 2.15. The grayscale however is not as flat as I like. The color blue takes a big nose dive starting at about 80 to 100 IRE. This causes the brighter whites to tint to green. Even with these issues I would choose a calibrated Dynamic mode for my bright room viewing, especially when watching less accuracy conscience content like sports and news.

Last but not lease is 4K HDR. I used Digital Cinema Mode for this calibration. Like Cinema Mode I used for HD 1080p, the color gamut performance is excellent with it adhering very close to the P3 spec, which is where most current 4K HDR displays are aiming for.

Epson’s first stab at HDR with their 6040/5040 models offered 4 HDR presets along with Auto. When the projector was set to Auto, it defaulted to number 2. Problem was number 2 is a little dark (crushed blacks) (and dark mid brightness areas –art). Now with the LS10500 they have added an Auto Bright mode which defaults to the preferred number 1 HDR preset.

Default grayscale (white balance) had a blue push in the upper whites but after calibration it improved a bit but not to the same accuracy you get with HD 1080p. ETOF (gamma) was quite good.
