Cine4Home. Epson EH-LS10000

Ekki also confirms that large convergence issues are common with these models too. You're more likely to receive an Epson LS series projector with poor uniformity, poor convergence and an issue with optical softening with eshift engaged than you are with a JVC. The quality control with these issues just doesn't seem to be there on these Epsons. If you don't believe me, feel free to read cine4home's write ups on these units. Considering how many units Ekki and and his team receive, calibrate and sell, I wouldn't hesitate for a second in believing him about such things.
Forty per cent of the test candidates
did not have the Cine4Home Edition criteria, which were not arbitrarily chosen by us, but were based on the better devices and the quality of the competition in this price class. Here, Epson should quickly improve quality standards in manufacturing.
At least three of the LS10000s we saw showed rough convergence deviations or optical blurs. For a device, the convergence deviations were so large that they could no longer be corrected with the "panel adjustment" of the image menu.In a fourth device the sharpness was adjusted in the half-hour clock so that a continuous post-correction was necessary. This is also not reasonable in this price class.
Regardless of the high series, the "4K-Enhanceent" basically provokes a loss of edge sharpness of the native FullHD resolution.
In this category, we can not give an absolute all-clear. Although the vast majority of the test copies were error-free, a device showed more than one pixel error
Therefore, we advise you to check the exact Pixel-Check to prevent bad surprises at home.
In terms of color uniformity, the LS10000 is at its best: none of our subjects showed serious color clouds, the discolorations in the marginal area were always below 250K deviation,
Brightness after calibration
About 30% of the light lost by the calibration on the D65 Videonorm, there remain about 950 lumens
The lower limit, according to the normal series spread, is 900 lumens
"DCI" mode 750 lumens, lower limit 700 lumens.
Contrast after calibration
Depending on the zoom and mode, the native contrast is an average of 15,000:1 to 25,000:1.
This native contrast is quintupled up to 75,000:1 to 100,000:1 by a dynamic LED control.
The lower limit for the Cine4Home edition is drawn according to the standard spread at 13,000:1 natively and 65,000:1 dynamically .
The factory settings of all LS10000 tested by us already lead to a very good color neutrality, which can be optimally optimized to the Kinonorm by CMS (see below). This is exemplary and meets the high price class.
Cine4Home. JVC X-500
devices with strong streaking have not yet come to us.
JVC brochure "Be aware that due to the complexity of the manufacturing process, the presence of a few defective pixels in the D-ILA chips used is normal (under 0.01% are constantly on or off"
In other words: JVC officially accepts no liability, up to a number of 200 Pixel errors (no matter which color or whether always luminous or always black), but declares this upper limit as technically "normal".
Many X500 have one or two blue glowing pixel errors in black, some light, others dark.
Most of the X500 / X700 are within the tolerable range of <290K deviation, outliers who exceed these limits (and thus also become visible in films) are very rare in JVC,
but devices with almost perfect homogeneous color temperature are also rare.
Brightness & Contrast after calibration
Zoom max Lamp high 1,030 Lumen, lamp low 710 Lumen. Iris full open 26,000:1
Zoom max Lamp high 460 Lumen, lamp low 300 Lumen. Iris smallest 45,000:1
Zoom min Lamp high 880 Lumen, lamp low 610 Lumen. Iris full open 30,000:1
Zoom min Lamp high 360 Lumen, lamp low 260 Lumen. Iris smallest 49,000:1
The adaptive aperture increases the dynamics gain to an average of 350,000:1
An X500 must achieve at least 950 lumens in the calibrated brightness (large zoom) and combine these with a contrast of 25:000. On the basis of these values one can see that the average fluctuation in average is also about 10% in this generation
The ANSI (chessboard) contrast has not changed in the new generation, it is in the standard cut at 250: 1 (all models).
This Color Management also works well and most of our devices have been fully calibrated to the HD / Rec709 video format. The emphasis is on "most", because unfortunately there were also various outliers in this regard:
Problems of some X500: Their native green point is too yellowish and therefore can not be balanced despite color management. A perfectly standard calibration is not possible with the affected devices.
HDMI handshake problems
All the first-line devices that were shipped showed problems with HDMI connections, they did not accept resolution changes. JVC has remedied by a firmware update, which should be imported exclusively by the authorized specialist trade.
