Supports 4K 60p (3840X2160p (50/59.94/60Hz) YCbCr 4:2:0 8bit, 4096X2160p (50/59.94/60Hz) YCbCr 4:2:0 8bit)
Does this mean the YCbCr 4:2:0 is the MAXIMUM color coding supported at UHD / 60Hz with the new firmware?
Here are a couple of excerpts from the thread on the SpectraCal forum. Since the X900 has only a two-point grayscale adjustment, it looks like a CalMAN BT.1886 calibration is not possible.
Using BT.1886 over 2.4 or 2.2 power formula is only a valid option if you have access to a multi-point greyscale or multi-point gamma function during calibration, correct? I would think a simple 2-pt greyscale or pre-defined built-in Gamma options (-1, 0, +1) it would be best to stick with 2.2 or 2.4 power formula. I have a DLP that would probably greatly benefit from a BT.1886 curve, but if I understand this correctly, the only way I could dial in a BT.1886 curve on this Mitsubishi would be with a Radiance or similar VP.
Correct, you won't be able to finely tune your gamma curve without having at least a 10 point greyscale adjust.
A disappointed Canadian owner of XBR-65X900A:
bought it Nov., 2013, today found out 4k video on USB disk won't play. So for anyone in Canada, buying this TV is of little use:
- not support for X1 player
- not support for streaming - meaning all 4K samples I saw on TV from YouTube app were actually not 4k
- not support for playing 4K contents through usb - so no use to download them from internet
so what use it has in Canada?
Extremely disappointed. I am finding a way to return it.
You asked a right question, indeed I didn't do much research before purchase, I was just impressed by the demo picture on the tv in the Best Buy store.
The issue is not really if there are 4k contents, it is that the tv in Canada has no way to play them. Yestrday I downloaded some contents to USB and tried to play it on the tv, then got "contents not supported" message. Then I read online, found out the no means can be used to play it in Canada, see this doc:
Do 4K TV models support playback of 4K content through the USB input or streamed through the Internet?Article ID: 44053 | Last Updated: 10/23/2013
The 4K Ultra HD TV can support 4K content through the following connection:
If using the USB input:
•4K Photo is supported.
•4K Video is not supported.
If using an HDMI connection:
•4K camcorder with an HDMI output
•4K computer with an HDMI output (U.S. only)
•4K Ultra HD Media Player model FMP-X1 (U.S. only)
NOTE: Streaming 4K from the Internet is not supported.
You know, just wanting to play some 4k contents one way or another by this $5000 box is not a too high expectation. I would be happy if I have just one way to do so. But according to the article as above, except a "4K camcorder", there is no way to play any 4k contents in Canada. We cannot buy a X1 player to do it as I guess it is not compatible with the one sold here so that is why we don't have a few x1 player in purchasing it in Canada. I first thought that was a better sale policy in US, now I know it is a hardware issue.
