Technical Bench Tests
Objective bench tests of the Epson LS10000 were carried out using CalMAN 5.4 software from SpectraCal, X-Rite i1Pro2 and C6 meters, a DVDO AVLabTPG, and APL 18% test patterns. YCbCr was used as a colorspace as it provided the best chroma alignment on the Epson LS10000. The Epson stores individual memories for YCbCr and RGB sources, so make sure to calibrate both modes if you are using one or some sources will look worse.
Pre-calibration the THX and Natural modes provide similar performance. Both are relatively accurate but excel in different areas. The THX mode has more accurate grayscale and color checker while the Natural mode did best with gamma and saturations. I used THX for the pre-calibration measurements in the end as I felt they were better balanced. Without a calibration the Epson LS10000 is semi-accurate but not nearly as good as it can be.
Post-Calibration the LS10000 is virtually perfect. The Gamma tracks the BT. 1886 standard almost perfectly, the grayscale error is minuscule, and colors are very accurate. Every aspect of the image improves after a calibration and the Epson CMS does a good job of not introducing banding or artifacts during the calibration. There wasn’t much that stands out from the post-calibration aside from being a very accurate image.
With Game Mode enabled, the LS10000 has 57ms of input lag. With it disabled this rises up to 107ms. If you enable the 4K interpolation modes the input lag was no longer measurable. The Epson LS10000 has enough lag that I had to adjust my processor to deal with it, but once that was done it works fine.
After the calibration there were 508 lumens in Eco mode with the Iris open all the way. Moving to Normal lamp power bumps that up to 711 lumens, and Extra Bright was 970 lumens. Fully calibrated this is a very good lumens number and even if it falls 10% over the 20,000 hours you still have almost 900 lumens to drive a screen. Because of this the Epson LS10000 will pair nicely with a very accurate screen like the Stewart Snomatte 100 or even with an acoustically transparent one.
Finally, while content that uses the DCI/P3 gamut won’t be here until Winter, the Epson LS10000 can reproduce 96.8% of this color gamut. So when you get an UltraHD Blu-ray player, the LS10000 will be able to display virtually all the new colors that it is capable of, and more than any TV I have measured at this point.
|Average Grayscale dE2000:||3.80||1.38|
|Average Saturations dE2000:||2.45||1.17|
|Average Color Checker dE2000:||1.57||1.74|
|Summary:||Before calibration the Natural and THX modes offered good performance. THX was better with the color checker and grayscale, while Natural held the edge with gamma and saturation. Using THX as the starting point for the calibration, getting better results out of the LS10000 is easy. It calibrates to be accurate and has a very good contrast ratio. Since the laser should shift very little over time, you can calibrate it when it is new and have the same image years down the line.|
