No issues for me. If you are unable to connect to the update server, simply download the firmware and flash via USB or disc.

Get the file from CA. You can follow the Oppo instructions. https://www.oppodigital.com/blu-ray-...e-65-0131.aspx

Thanks for the response. That was my first shot, but it seems that CA does not offer the capability to update CXUHD via USB, even though the device itself seems to be capable of it (at least I didn't find out how I can get the firmware file). I'm in touch with CA support, but they keep on offering the most obvious solutions like doing factory reset etc...

I’ve put my BDMV movie backups into AVCHD folders so that will play over the network and they work fine. However I’ve tried TV shows Nikita and V (2009) but they won’t work. V won’t even work via USB.

Any ideas?

Yes I did. It says the modifier is not required for USB connection. Folder structure didn’t work for me with V.

Only problem I have seems to be backups of TV shows, movies are fine.

Greetings.

I am running a CXUHD directly to a Samsung UN65NU8000 via a Monoprice HDMI cable (premium certified for HDR/4K video pass) for visuals and another HDMI 1.3a cable from the player's audio only out to an older Onkyo AVR (for bitstreaming of TrueHD and DTS-HD MA signals since the older AVR isn't 4K/2160 compliant).

I was wondering if anyone could help me with questions I have regarding what the player is sending to my display with all parameters in the CXUHD set to AUTO (that is, resolution/HDR/color space/color depth) because I have been getting conflicting feedback on this, even from my contact at Cambridge...

Okay, so with everything set to AUTO, my CXUHD's information panel reads as the following when I press the INFO button on the remote while viewing a 4K Blu-ray (running HDR10; my Samsung doesn't support Dolby Vision):

MEDIA INFORMATION:

Resolution: 3840 x 2160
Frame Rate: 23.976p
HDR Format: BDMV HDR
Color Space: BT2020 YCbCr 4:2:0 10-Bit
Video Codec: HEVC
Current Bit Rate: 46.1 Mbps
Max Luminance: 4000 Nits
Min Luminance: 0.005 Nits
Video Bit Rate: 43.5 Mbps


HDMI (MAIN) OUTPUT INFORMATION:

Resolution: 3840 x 2160
Frame Rate: 23.976p
HDR Format: HDR
Color Space: BT2020 YCbCr 4:4:4 12-Bit


Now, aside from the downfalls of my display's tech -- which is, unfortunately, edge-lit...a thread/discussion for another time -- I don't see any obvious or blatant issues when viewing HDR-encoded Blu-rays (the nasty blooming I get from the edge-lit panel is something else)...but my question is, does the data look correct taking into consideration the specs of the Samsung NU8000 panel?

I just want to be sure my display is "speaking" to the CXUHD properly when the HDMI handshaking is going on with everything in the player set to AUTO...does the 4:4:4 12-Bit look right?

Thanks in advance.

^ Yes. That’s normal output for 4K/24 HDR10 video into a compatible display.

Thank you so much for your response, Bob! It's truly appreciated...

I see you are something of a guru for all things Oppo, so being that the CXUHD is practically a 203 clone, I take your expertise at full value.

Just a quick follow-up question: Is it correct that the player is sending 12-Bit color depth over to my Sammy when it can't display 12-Bit video, per se? Is the display then just "downscaling" that signal so to speak to 10-Bit depth?

And these readings seem correct for an NU8000 display (this is the model that's just before the QLEDs)?

Thank you, again, for your assistance!

^ I don't know enough about your display to say this is the "best" video format to send it, but it is certainly the one I'd expect the display to be getting in most setups, so it SHOULD handle it properly. You'll have to check in the forum thread for your display to see if there are any known problems with it handling this input format.

It is common for consumer displays to render pixels at less than 12-bit, but the video processing path prior to lighting up the pixels may very well be 12-bit or even 14-bit. The extra bit depth in the video path allows better handling of rounding during processing.

I do not know whether your particular display truncates the incoming 12-bit video to 10-bit as the first step on input, or as the last step before lighting up the pixels.

A couple of other things I wanted to ask you, Bob (seems I don't have access to "editing" features here yet for my posts)...there is such thing as 14-Bit color depth? Haven't heard of that...

And would you just leave everything at AUTO output in my situation, as I am doing, with regard to the CXUHD's parameters (HDR/Color Depth/Color Space)? Leaving the player on AUTO Resolution seems to always send the Samsung 2160 video, so that seems to be working properly, but I was curious if I should leave the rest of the settings on AUTO...

^ 14-bit video is not something you can send over an HDMI cable. However some TVs use a 14-bit video path for their internal video processing between the inputs and the pixels.

-------------

The current HDMI specs do not allow 4K/60 video in the format YCbCr 4:4:4 12-bit. (The bandwidth for that is too high.) So if you are sending 4K/60 video the player has to send something else -- either YCbCr 4:4:4 8-bit, or YCbCr 4:2:2 12-bit, or YCbCr 4:2:0 12-bit. 4:2:2 or 4:2:0 are the common result. 4K/60 video gets sent for NTSC DVD discs (upscaled to 4K output) or 1080i Blu-ray discs (typically live concerts) or the few 4K/60 UHD discs out there (most UHD discs are 4K/24).

Now the content on any of these discs is 4:2:0. And whether it is done in the player or the TV that has to be raised to first 4:2:2 and then 4:4:4 before you can light up the pixels, so in a perfect world it really makes no difference -- everything starts out as 4:2:0, and eventually ends up as 4:4:4. But there are many examples of TVs which are not perfect, and actually do a poorer job with some input formats than with others. That means you have to CHECK the correct functioning and calibration of your TV for each video format you plan on sending to it, to see if there are any formats you should avoid using due to peculiarities (read "bugs") in the TV.

The fewer formats you intend to send, the less checking you have to do.

It turns out the HDMI specs also do not allow you to send 4:2:0 for anything other than 4K/60 or 4K/50. So you can't send 4K/24 as 4:2:0 or even 1080p/60 as 4:2:0. But you can send 4:2:2 for everything. So in my case I've set my OPPO to send 4K (/24 or /60) as YCbCr 4:2:2 12-bit to my LG TV. And, as it turns out, my LG has no problem with that input format, so that's all I need.

-----------

The Auto settings ask the TV for its preferred input format. Usually (as in your case) that comes back as the best the TV can handle. But there are examples of TVs which instead publish a "safe" input format. For example a 1080p TV might say its preferred input format is 1080i. Or a 4K TV might say its preferred input format is 1080p. In such cases, you would not want to use the Auto video Resolution setting. Similarly, some TVs may ask for 8-bit when they can handle 12-bit just fine. And some TVs (projectors were notorious for this) say they can only handle /60 video even though they actually handle /24 perfectly well. Again, in your case the Auto settings are producing the "normal" result, so no problems.

I'm wondering if I understand correctly what this player does with Dolby Vision. I have a TV and projector that are both 4K and HDR10, but not Dolby Vision. I'm assuming, with HDR settings left on AUTO, that DV and HDR10+ will be converted to HDR10. I have the S&M UHD HDR Benchmark disc and the menu in the Montage section says that DV and HDR10+ will be converted to HDR, and that appears to happen, but I'm assuming this would apply to any DV/HDR10+ content, not just that disc.
Alternatively, I could choose Off (BT.709) or Off (BT.2020) to somehow tone map any HDR to SDR with whichever of the two colour spaces. Or, I could choose to Strip Metadata to also send out an SDR BT.2020 signal.
Is the above correct or sort of correct?
Also, what is the difference between Off (BT.2020) and Strip Metadata?
Any enlightenment on this would be appreciated.
Thank you,
Morgan.

Can anyone suggest an iOS control app to link up my PC based files with the CXUHD. I’m looking for something that gives fancy artwork and movie synopsis. I use mconnectHD and that works with Serviio as a dlna server and gives some artwork but no movie summaries.

I'm looking for a player that's built like a tank, plays sacds (willing to add a dac), and has all the 4k bells and whistles (like hdr10+).

This player is a few years old, but does it still tick all the boxes?
The Panasonic is out of the question due to lack of sacd, and the pioneer's may not be getting hdr10+...

To the best of my knowledge you can’t do better than the Cambridge CXUHD for what you’re looking for.

I second this option list. If playing SACDs is the primary driver, one can’t do better than any of these.

I love my CXUHD- given latest FW update, it brought it on par with the Oppo, so I’ve stopped looking!
