    NUC7I5BNH - HDMI 2.0 Issues

    CitizenNuc

      Hi All,

      I am experiencing flickering when trying to set my display to 3440x1440.
      In summary, I believe it is a HDCP issue or some statically configured expectation within the driver of how a HDMI 2.0 port should behave when communicating with it.
      Below are the troubleshooting steps I have performed along with the hardware specs.

       

      Intel NUC Hardware
      Model: NUC7I5BNH
      OS: Win 10 Home x64
      Memory: Single Kingston ValueRAM (Part Number: KVR21S15S8/4, 4GB Module, DDR4 2133MHz, Non-ECC, CL15, 1.2V, Unbuffered, SODIMM)
      HDD: WD M.2 Blue 250GB (WDS250G1B0B, 250GB, SATA III, 6Gbs, M.2 2280)
      Firmware and Drivers: The latest drivers and BIOS Update listed in the 'Drivers and Downloads' page for this product, have been installed for each component in the NUC, up to the date of this post (including the HDMI 2.0 Firmware Update).

       

      TV's:
      Sony KDL-65X95000B (4K 60Hz TV, 4:2:0 8-bit, Not HDR compatible)
      Sony KDL-46Z4500 (1080p 50Hz)

       

      HDMI Cables:
      Hi-Speed cables 2K/4K V2.0 from EzyHD - https://www.ezyhd.com.au/
      XBox One S provided HDMI cable

       

      Thunderbolt to HDMI Adapter:
      Moshi USB-C to HDMI Adapter - https://www.moshi.com/usb-c-to-hdmi-adapter
      NOTE: I understand the compatibility only states MAC products, but it works, and exhibits the same behaviour as the HDMI port, however I'm not really concerned with this (it's HDMI that concerns me)

       

      Desktop PC:
      OS: Win 10 Pro x64
      Graphics Card: NVidia GTX 1080 TI

      Monitor: Acer X34 Predator (DisplayPort 1.2a, HDMI 1.4)

       

      Troubleshooting:
      Sony KDL-65X95000B
      1) My desktop PC has NO issues displaying the TV at 3440x1440 resolution - No flickering
      2) My XBox One S has NO issues detecting the TV as 4K capable, and has no issues displaying the TV at 3440x1440 resolution
      3) My FetchTV box has NO issues detecting the TV as 4K capable, and has no issues displaying the TV at 3440x1440 resolution
      4) My Surface Pro 2 has NO issues displaying the TV at 3440x1440 resolution - No flickering
      5) The NUC shows that the recommended display settings for the TV is 1920x1080 (even though it is a 4K TV). I have no flickering at this resolution.
      6) As soon as I  set the Display settings to 3440x1440, I get the message saying that this is not the recommended display settings for this device, and I begin to get flickering. It is stable at 1920x1080.
      7) I have also tried various refresh rates, 30Hz, 59Hz, 60Hz etc....but still get flickering.
      8) Various power cycle methods on the TV and NUC including - Rebooting, Sleep, Shutdown, Removing power sources, changing inputs, powering up the devices in specific sequences etc..., sometimes provide stability at the 3440x1440 resolution (I have more stability using the Thunderbolt to HDMI Adapter), however even when its stable, i can verify its still not working poperly when trying to watch 'Foxtel Go', where I get no picture (see further down regarding Foxtel Go)
      9) All HDMI ports on the TV have been tried
      10) CEC has been tried ON and OFF on the TV
      11) All display and sound modes have been tried on the TV
      12) I have tried the TV's supplied HDMI splitter which produces the same reults
      13) When using other HDMI inputs that aren't HDMI input number 1, it sometimes switches the TV's inputs to HDMI 1 (may have been more prominent before I disabled CEC)

       

      Foxtel Go
      1) I cannot watch any channels in Foxtel Go when using it through the Sony KDL-65X95000B using HDMI at 1920x1080 resolution (Thunderbolt to HDMI Adapter doesn't work either, however this is expected behaviour so it's not a consideration)
      2) I have tried all of Foxtel Go's troubleshooting steps for this particular issue, however I have verified it is not an application issue - see the next 2 points
      3) When I plug the NUC in to my Desktop PC monitor, Foxtel Go works
      4) When I cast my desktop on the NUC to a chromecast, which is also connected to my Sony KDL-65X95000B TV, I cannot watch any channels. However, as soon as I unplug the HDMI connection from my NUC to the TV, and still casting to the chromecast, I can watch channels
      5) Its clear that there is an issue with the HDMI 2.0 here

       

      Sony KDL-46Z4500
      1) When using HDMI, I just get a black screen - doesn't work at all at 1920x1080
      2) When using the Thunderbolt to HDMI Adapter, it works at 1920x1080 (Foxtel Go doesn't work as expected as we are using the Thunderbolt to HDMI Adapter).

          Apologies, I made a mistake in my original post by specifying incorrect display resolution figures, and cannot edit the original post so I have updated as per below:

           

          I am experiencing flickering when setting my TV display to 3840x2160 using HDMI.

          In summary, I believe it is a HDCP issue or some statically configured expectation within the driver of how a HDMI 2.0 port should behave when communicating with it.

          TROUBLESHOOTING

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

          Sony KDL-65X95000B

          1) My desktop PC has NO issues displaying the TV at 3840x2160 resolution - No flickering

          2) My XBox One S has NO issues detecting the TV as 4K capable, and has no issues displaying the TV at 3840x2160 resolution

          3) My FetchTV box has NO issues detecting the TV as 4K capable, and has no issues displaying the TV at 3840x2160 resolution

          4) My Surface Pro 2 has NO issues displaying the TV at 3840x2160 resolution - No flickering

          5) The NUC shows that the recommended display settings for the TV is 1920x1080 (even though it is a 4K TV). I have no flickering at this resolution.

          6) As soon as I  set the Display settings to 3840x2160, I get the message saying that this is not the recommended display settings for this device, and I begin to get flickering. It is stable at 1920x1080.

          13) When using other HDMI inputs that aren't HDMI input number 1, it sometimes switches the TV's inputs to HDMI 1 (may have been more prominent before I disabled CEC)

          14) When I plug the NUC in to my Acer monitor using HDMI, it has no problems displaying it correctly at 3440X1440, with no flickering. MOst likely it has no issues because it is HDMI 1.4.

           

          Foxtel Go (Pay TV Streaming Service)

          NOTE: Foxtel Go requires a correct handshake connection otherwise it will not work due to HDCP, and I am using this as a perfect example of highlighting how the HDMI 2.0 interface is not communicating correctly from the NUC to the TV over HDMI.

          1) I cannot watch any channels using Foxtel Go on my NUC when connecting it to the Sony KDL-65X95000B TV using HDMI at 1920x1080 resolution (Thunderbolt to HDMI Adapter doesn't work either, however this is expected behaviour so it's not a consideration). Not only does it not display the channel I select, it also begins to flicker.

          2) I have tried all of Foxtel Go's troubleshooting steps for this particular issue, however I have verified it is not an application issue - see the next 2 points

          3) When I plug the NUC in to my Desktop PC monitor, Foxtel Go works with no issues

          4) When I cast my desktop on the NUC to a Chromecast, which is also connected to my Sony KDL-65X95000B TV, I cannot watch any channels. However, as soon as I unplug the HDMI connection from my NUC to the TV, and still casting to the Chromecast, I can watch channels

          5) When I run Foxtel Go from my PC connected to the Sony KDL-65X95000B TV using HDMI at 3840x2160 or 1920x1080 resolution, Foxtel Go works with no issues

          6) Its clear that there is an issue with the HDMI 2.0 communication from the NUC to the TV.

           

          Sony KDL-46Z4500

          1) When using HDMI, I just get a black screen - doesn't work at all at 1920x1080

          2) When using the Thunderbolt to HDMI Adapter, it works at 1920x1080 (Foxtel Go doesn't work as expected as we are using the Thunderbolt to HDMI Adapter).

            Hello CitizenNuc,

            Thank you for contacting Intel Communities.

            I am sorry to hear you are having issues to display 4K when using the Intel® NUC. Can you please provide the following information to better assist you?

            I was unable to find information about the Sony KDL-65X95000B but I did find a similar model number (KD-65X9005B). Can you please verify this information?
            After providing all the information above, do the following:

            1. Disconnect the Intel® NUC from the Internet
            2. Uninstall the graphics driver using the device manager method 
              1. Check the "remove driver software from this device" box when uninstalling. (in case the option is displayed)
            3. Perform this process the necessary times until you see "Microsoft Basic Display Adapter" in the device manager, once this is done, the default resolution should be 3840x2160 without any option to change it. 

            Please let me know if the flickering persists after uninstalling the graphics driver.

             

            I hope to hear from you soon.

             

            Best Regards,
            Juan V.

              Thanks Juan for the quick response.

               

              I am using a single display only.
              The Sony TV model is KD65X9000B - http://www.sony.com.au/local/product/kd-65x9000b
              Graphics Driver Version: 21.20.16.4678
              BIOS Version: BNKBL357.86A.0046.2017.0503.1744

               

              After uninstalling the graphics driver to revert back to the "Microsoft Basic Display Adapter", the default resolution is 1920X1080 with no option to change it. So it doesn't seem to recognise the TV's 3840x2160 resolution.
              The Graphics driver report below shows that the maximum refresh rate at the 3840 x 2160 resolution is 30p Hz, which goes against what Sony have provided in their product specifications. It did however fix the Foxtel Go issue and I could watch channels, although it no longer had sound due to the driver being uninstalled.

               

              It does look like Intel driver is causing the flickering and the Foxtel Go issues, and the Microsoft basic display driver not being able to recognise the 3840 x 2160 resolution of the TV.

              Do you have any other ideas of getting the graphics to recognise the TV at 3840x2160 60Hz resolution and supply audio over HDMI?

                Hi CitizanNUC

                I have got HDMI output without 4k 60Hz problem previously too.  I solved it by set up my TV HDMI mode to HDMI 2.0.  Many TV leaves default HDMI to 1.4 to keep some old TV box work properly.  My be you can check if there is similar HDMI mode set up on your TV/Monitor.

                Regards.

                  by the way,  I saw you use type-c covert to HDMI2.0.  I am directly use NUC HDMI2.0 port to my monitor/TV. 

                  driver ver4678 do flicks on NUC HDMI port at 4k 60hz,  I down to ver4664 to keep away from flicker.

                  I have no experience on type-c to HDMI2.0

                    Thanks WW6302,

                    There is no option on this model TV to switch the HDMI mode to 2.0. As mention in my original post, it has no issues with my other devices.

                    I am not using type-c to HDMI 2.0. I have only supplied that information to advise that I have tried it, but I am not using it. I am using HDMI.

                      Hi CitizenNUC

                      first, Intel graphic driver version 4678 do flickers, and was proved by Intel engineer.  You should down grade the graphic driver to version 4664.

                      I have tested microsoft basic driver too.  The Microsoft driver said that HDMI port output running at 3840*2160@64Hz, It was confuse me some time for it led's me to belieave the HDMI was working at 2.0 version.  But when I checked the TV real input mode, I found it is 3840*2160@30Hz, only HDMI1.4. not as windows said 3840*2160@64Hz.

                      I do not know if your other PCs do worked at 4k@60Hz.  Since i am reading your Sony TV manual PC input mode, I saw no 4k 60hz was supported.

                        Hi WW6302,

                        At least the Microsoft Basic Driver showed 3840*2160@64Hz for you, however as I said previously, it only shows 1920x1080 for me.
                        You say you checked the TV real input mode and found it is 3840*2160@30Hz and only HDMI1.4 - Where do you see this information on the TV?

                         

                        It is interesting though to see in the Sony manual that the connecting a PC acts differently to other devices connected. The TV specifications advise it can do 3840x2160 60p, however for PC its 3840 x 2160 @ 30p. Typical that this was hidden away as a gotcha against the global specs.
                        Video Specifications for the TV as shown here - http://www.sony.com.au/support/product/kd-65x9000b
                        3840x2160/24p, 3840x2160/25p, 3840x2160/30p, 4096x2160/24p, 3840x2160/50p (YCbCr4:2:0 8bit), 3840x2160/60p (YCbCr4:2:0 8bit), 1080/24p (HDMI only), 1080/60i, 1080/60p (HDMI / Component)
                        1080/50i, 1080/50p (HDMI / Component), 480/60i, 480/60p, 576/50i, 576/50p, 720/60p, 576/50p, 1080/30p (HDMI only), 720/30p (HDMI only), 720/24p (HDMI only)

                         

                        It is strange that I have no flickering at all when using my desktop PC at 3840x2160/60p and I can run Foxtel Go with no issues. I also play games at that resolution with no issues on the TV.

                         

                        For now I have gone back to driver version 4664 and running the resolution at 3840x2160 30p. The TV settings suggested in the manual were already tried unknowingly anyway. I will see how it goes overnight in regards to the flickering.

                        However I still have the issue with Foxtel Go not playing any channels though when using either Intel Driver 4664 or 4678 at both 1920x1080 or 3140x2160 on this TV. Again as I have mentioned before, I have proven that there is something in the drivers that is causing it, as when I revert back to the Microsoft Basic Driver, it works fine. I would like Intel to provide an answer to this as it points to a signal issue and could help others with similar issues that aren't necessarily Foxtel Go related.

                          Hi CitizanNUC

                          My TV can display input mode (resolution and refresh rate) by press TV remote OK.  I am not sure if Sony have similar function.

                          as I know, although both PC and Video signal are all input through HDMI, but these signals are very different.  Video signal is YUV(YCrCb 4-2-2 or less) format and range 16-235,  which carries less information than PC signal.  PC signal is RGB format and range 0-255. 

                          For TV, deferent signals may not be processed the same way.  According to your information about your TV 4k 50hz 60hz video mode was declared specifically on (YCbCr4:2:0 8bit) format, so I think your TV HDMI looks like a “pseudo HDMI2.0.  I suggest you should consult SONY, to make sure your TV can work at 4k60Hz when connected to PC.

                          Regards

                            Hi WW6302,

                            Lets clear the mud here.

                             

                            I am well aware of the TV's colour space limitations of YCbCr4:2:0 8bit, and this has never been a concern in this case. That's why I posted it in the original post. The inputs are still HDMI 2.0 certified though, but it just cannot support the wide colour gamut, which is another story in itself on how Sony burnt a lot of us early 4K TV adopters, who now can't play the new 4k Ultra HDR DVD's due to this limitation and HDCP2.2. Lets leave this one alone.

                             

                            Where are we at now from my original post ?
                            1) We have found in the last few posts that as per the TV's manual, this TV can only support 3840 x 2160 @ 30p  when specifically using a PC connected to it. That's fine, I can live with that, however as mentioned, I have no issues or side effects in any form when using my GTX 980 TI connected to the TV.
                            2) We also found that the Intel HD driver 4678 causes flickering, and I have reverted back to 4664. So far so good at 3840 x 2160 @ 30p, and I will continue to monitor. I am also going to try my Parents LG B6T TV soon to see what behaviour unfolds.
                            3) The "Foxtel Go" issue still remains.
                            - Yes its an application. No its not an application issue.
                            - Why should Intel care? Because it is good example that can hopefully assist Intel in finding bugs within the driver that could fix many other issues using TV HDMI inputs. No other PC device I have, has the issue.
                            - Troubleshooting performed:
                            a) Using Intel HD Driver 4664 or 4678:
                            - Foxtel Go DOESN'T WORK when connected to the TV over HDMI
                            - Foxtel Go WORKS when plugged in to the Acer x34 Predator monitor over HDMI
                            b) Using the "Microsoft Basic Display Adapter":
                            - Foxtel Go WORKS when connected to the TV over HDMI (This in itself proves the driver is causing the issue)
                            c) When the NUC is connected to the TV using HDMI, and I cast my desktop on the NUC to a Chromecast which is also connected to my TV, Foxtel Go DOESN'T WORK.
                            - However, as soon as I unplug the HDMI connection from my NUC to the TV, whilst still casting to the Chromecast, Foxtel Go WORKS.
                            d) Using Foxtel Go on my desktop PC connected to the TV using HDMI:
                            - Foxtel Go WORKS at 3840x2160 or 1920x1080 resolution
                            e) Using Foxtel Go on my Surface Pro 2 connected to the TV using mini display port to HDMI cable:
                            - Foxtel Go WORKS at 3840x2160 or 1920x1080 resolution
                            f) Last night I thought I would try a dual display setup, using my Acer x34 Predator monitor as the primary display, and the TV as the secondary.
                            - I thought to try this because I knew Foxtel Go WORKS when plugged in to the Acer x34 Predator monitor over HDMI, and then use the type-c to HDMI connection to the TV.
                            - Well this discovered another issue.
                            - What happens is, the TV will ALWAYS be the Primary Display. Because of this bug, I could not successfully try this idea out.
                            - No matter what connection combinations I tried, the TV will ALWAYS be the Primary Display. Such as (Monitor = HDMI) and (TV = Type-C to HDMI) / (TV = HDMI) and (Monitor = Type-C to HDMI) / In combination with BIOS changes where Primary IGDP = HDMI/Thunderbolt and/or Secondary IGDP = HDMI/Thunderbolt.
                            - As for the OS, within Windows, the 'Make this display as Primary' checkbox is ON for the Acer monitor, however when you press the keys WIN+P, 'Second Screen Only' is highlighted, so even Windows is confused.

                              Hi CitizenNUC

                              Since I am only an ordianry user same as you, and I have shared all of my experiences with you, now I have no more idea on your problems.  I do hope Intel and Sony engineers will give you perfact solutions.

                                Hi CitizenNUC

                                I have checked HDMI2.0 tequenic data and find that there are TWO kind of HDMI2.0 on TV.  According to your TV manual,  it is clear that your HDMI2.0 is level B.  Just a 10.2G/s maximium transport speed pseudo HDMI2.0.

                                124155zmzw1gbw7lml57s5.jpg

                                So it is Sony  should be blamed  for your TV can't work at 4k@60Hz when connected to PC. It seems nothings wrong in INTEL NUC HDMI out put.

                                Regards

                                  Hi WW6302,

                                   

                                  I appreciate your help, but please stop referencing 4k@60Hz. I am aware of the TV's limitations.

                                  Please read my response carefully....I am not interested at all in this ability.

                                  I do also appreciate your help in advising to roll back the driver, as it seems to be OK so far with the flickering issue.

                                   

                                  From my previous post I will reference again the issue that still remains, as I am yet to have a response from Intel.

                                  3) The "Foxtel Go" issue still remains.

                                  - Yes its an application. No its not an application issue.
