Big difference if you are playing 4K Ultra HD disks on the Samsung K8500 and your TV does HDR. Some difference if your TV doesn't do HDR and you are playing 4K Ultra HD disks on the Samsung (you still will have actual 4K instead of the upconverted 4K). Little if any difference when playing regular Blu Rays.

I would prefer to send bitstream audio from my K8500 to my AVR via HDMI2 and directly connect HDMI1 to my projector, as there have been several posts which suggest that this would lessen the bandwidth requirements on my video feed HDMI cable. However, I'm unable to find any reference that the player will internally separate the audio and video paths if cables are plugged into both HDMI1 & HDMI2. Can anyone verify that the audio stream is removed from HDMI1 when a 2nd HDMI cable is attached to HDMI2? Thanks!

Based on the generally accepted interpretation of the manual, if you connect cables to both HDMI jacks on the UHD BDP, you must select HDMI2 for audio output in order for the audio stream to be separated from the video stream.

Thank you for your response, but I'm unable to find any reference that indicates that this actually occurs; there doesn't seem to be any mechanism to identify HDMI2 as the sole audio stream. My interpretation of the instructions is that HDMI2 is to be used when an AVR does not support pass through, but this doesn't necessarily mean that this results in HDMI1 only carrying video. My set-up doesn't allow me to test this theory, as the projector doesn't have speakers. I guess the only way to verify the situation would be if someone who uses an AVR for audio distribution would connect HDMI2 to an active AVR audio input and connect HDMI1 to a television in order to see if the TV's speakers are still active when the TV's audio menu is set for the speakers being "ON".

It appears my Samsung player has some issues with Pacific Rim after the latest firmware update. It will not play the UHD or the Blu-ray disc, the disc icon just keeps spinning. I put the Blu-Ray in my Sony player and it works fine. Anyone else noticed this?

If it's not a BIG screen, it's not a theater...

Been playing with my new 4k equipment (see signature) for one week, updating, tweaking, testing, etc. Just finished enjoying Mad Max Fury Road 4k disc and it was awesome - flawless picture/sound! HDR kicked in fine, Atmos bit-streamed... No problems at all with hdcp or lip sync or blacking out or strange pixels. Everything in the player and avr is set to Auto/Passthrough, and using one hdmi cable from player to avr then one hdmi cable from avr to tv.

I tried it for you.

If I set the K8500's HDMI Audio Output setting to HDMI 1 and have my TV speakers setting turned ON, as expected the audio will be heard from the TV speakers since the player is hooked up directly to the TV.

However if I set set the K8500's HDMI Audio Output setting to HDMI2 (or Auto) with my TV's speakers setting turned ON, I hear nothing so I guess we can conclude that the audio stream is removed from HDMI1 when using Method 2 to hook it up and using the players HDMI2 (or Auto) setting but I am not convinced that is going to cure the issues you have been reporting regarding the menu being displayed at 4k 60Hz 4:4:4.

But hey, if you want to run another HDMI cable and give that a whirl no harm trying but since the Home menu doesn't have any audio associated with it, I can't see how this is going to help.

It is a waste of money. Just because it has a higher price tag doesn't mean it's better. But glad you got your issue fixed.

I was using HDMI Premium Certified cables so I know it wasn't the cables. Magically when I hooked up a Philips UHD Player none of the issues the k8500 had existed even with just a single HDMI cable through my AVR.

Guess adding the word expensive was incorrect of me.

I switched out my 18gbps rated HDMI cable for a 27gbps rated HDMI cable and that fixed the problem. Now I can run my 4K HDR10 Image w/ Dolby Atmos & DTS:X without any black screen cut outs. Doesn't matter if the cable you buy is gold plated or what and what certified, I'm convinced it was the increased bandwidth that solved my issue.

There is no such thing as a 27Gbps rated cable. The specification for HDMI 2.0b is 18Gbps. I'm glad the cable works, but they are selling cables with false marketing attached. HDMI Premium Certified cables are tested to function at full 18Gbps as per the latest spec at the listed length. There is nothing beyond that.

HDCP 2.2 has me worried..

I just got a Sony XBR65X850D and I own a Yamaha RX-V775 that apparently doesn't do HDCP 2.2. I have come to understand that every link in your av chain must do 2.2...


However, it does seem that I could use the two HDMI cables to split the image out to tv and audio out to receiver, correct?

Thanks!

FWIW, Monster Cable is promoting that certain of their cable lines have been tested to successfully pass a signal in excess of 27 Gbps. They don't claim certification, but do rate HDMI cable speed, probably on the basis of their own in-house testing.

Thanks, so much, for doing that leg work! I'll set the HDMI audio option to HDMI2 and see whether or not that will then be able to provide a "sparkle free" K8500 home menu screen over my (supposedly) certified 18Gbps cable with 4K60 4:4:4 (just as soon as my JVC PJ is returned from service at the end of this week). It sure would be nice not to have to resort to the "disc trick" every time that I power up the K8500.

I very much appreciate your reply to my recent post; I had not been aware of your S&V article. "Sparkles" and intermittent loss of connectivity were present with my 25' run of the Monoprice Cabernet as well as the 35' Monster Cable Ultra HD Black Platinum HDMI cables, consistent with your findings. BTW, have you ever tested the 30' Sewell Silverback S6 active HDMI cable? Their customer support "guaranteed" that there would be no problem transmitting 4K60 4:4:4 at 30' with that cable.

Audio takes up a fraction of the bandwidth used. The audio only accounts for a few megabits. While the video is over 12 Gigabits. Those few megabits should have little effect on bandwidth since it's literally only a fraction of the total bandwidth used.

It does not send audio over HDMI 1 when HDMI 2 is set for audio. Well I should say the two K8500's I've owned has never done it.

Hello,

Can this player be used to stream from Apple Store or Google Play rented movies?

Thanks a lot

I have not. When I contacted them about sending in a sample for testing, I never heard back. I've read of others trying it with no success though.

It seems to vary disc to disc. Worst is my Pacific Rim which takes over 1 1/2 minutes to load while other loads in about 10 seconds. Have you tried plugging directly into the TV and does the problem persist?

How long did you let the spinning disc icon run. I have the same problem with Pacific Rim. It take about 1 1/2 minutes to load but it will load eventually. It is strange as other disc loads in about 10 seconds.

And I'm saying it's an 18Gbps cable they attach a number to and price it accordingly.

4k60 4:4:4 with hdr and audio? I can do 4k60 4:4:4 with a 6 year old mono price bargain cable but it is marginal for hdr.

Thanks a lot


No, you need Apple TV or a device that runs android for either of those. The fandangoNow app does allow you to purchase movies to stream. It sure about rentals, I never looked into it.

4K60 4:4:4 isn't possible with HDR. 4K60 4:4:4 is already 17.8Gbps.

4K60 needs to drop down to 4:2:2 12-bits or 4:2:0 10-bit or 12-bit for HDR. The last 2 are actually a lower bit rate than 4K 4:4:4 8-bit.

But I'm sure you know this, so

I would have thought that the dynamic range of the colourspace is a separate thing and not related to which mode it's in. Ie just flag the data as "this is rec2020 colourspace and HDR" and the display does the mapping.

I agree that 4K60 HDR is possible in the 4:2:2 12-bits mode (17.8Gbps) or the 4:2:0 12-bit (13.4Gbps) or 10-bit (11.1Gbps) modes. I can't see how that means that that 4K60 HDR "isn't possible" in the 4:4:4 8-bit mode, though, which is also the same 17.8Gbps bitrate, and that's the mode that games are already using (AFAIK).

HDR10 is always 10-bit. Dolby Vision 12-bit. Dolby say DV can be split across 2 video streams of lower bit depth, but, first, there aren't any DV HDMI sources, until Chromecast Ultra arrives and all of those, in practice will be using 12-bit video modes. Right now, all available HDR sources using HDMI are HDR10 and that's 10-bit.

Seems Xbox One S uses 4:2:0: http://support.xbox.com/en-GB/xbox-o...l-requirements

Harder to get a clear statement from Sony, but I'm sure they are doing the same: http://blog.us.playstation.com/2016/...-ultimate-faq/
