    NUC7PJYH:  Poor HDMI 2.0 support. In search of a compatible TV (4K-60Hz-4:4:4).

    PeterNUC

      When I bought NUC7PJYH I planned to use a budget 4K TV as a monitor for it.  For that, it is critical to support 4K (3840x2160) resolution at 60Hz with 4:4:4 chroma sub-sampling. Since this is a part of HDMI 2.0 specification, I expected, that any HDMI 2.0 capable TV would work. Surprisingly, after a half-year research I could not find a 4K TV compatible with NUC7PJYH at HDMI 2.0. As a result, a $400 pc (NUC+Mem+SSD) is just lying around for half a year and waiting for a compatible TV to appear.  It looks like HDMI 2.0 support in Gemini Lake CPUs is “partial” at best and behaves very differently with different TV brands.

       

      A compatible TV should pass at least these basic tests (important for normal everyday usage):

      1. 4K-60-444 – It possible to configure the TV to work under Windows in native 4K resolution at 60Hz with 4:4:4 chroma subsampling.    
      2. NUC logo at POST – NUC logo is shown at boot time        
      3. BIOS – After pressing F2 at boot time one can get into BIOS (and see it).
      4. PC sleep-wake – After suspending PC and waking it back the normal picture appears.
      5. TV sleep-wake – After suspending TV and waking it back the normal picture appears.

       

      Below is a summary my not very successful research.

       

      I would greatly appreciate if you could share your positive/negative experience regarding TV models compatible with NUC7PJYH or NUC7CJYH. It might help me and other users in their search of a compatible TV. 

       

      Thanks,
      Peter

            Hello PeterNUC,
            As always, thank you for posting in our Intel ® Community.
            Your feedback is much appreciated as this post will work as a reference for other community peers that might be looking for compatible 4K televisions with our Intel® NUC Kit NUC7PJYH, and it will remain open for them to post their experience.
            In addition, I would like to share our official Intel® Product Compatibility list for 4K televisions
            There you will find 5 TV models that are Intel ®Validated.
            I hope this helps.
            Regards,
            Diego S.

              Hello Diego S.,

               

              Thank you for your message and for "Compatibility list for 4K televisions". I've seen it before. There are serious problems with this list:

               

              1. 3 of 5 mentioned TVs are not even 4K - just Full HD.
              2. It is not clarified which settings/scenarios are verified. And I strongly doubt, any attention was paid to HDMI 2.0 support (HDMI 2.0 is not even applicable to Full Hd TVs)
              3. The only 2 4K TVs mentioned there (LG 40UF675T and Samsung UA55JU6000) are old models. Even their specs (specifically, HDMI 2.0 support) is very hard to find, not speaking of the TVs.

               

              The list of Intel Validated Monitors looks more solid, but, again, nothing is said about what is "Validated". And again, some of them are just FHD, and some 4K do not support HDMI 2.0.  For example, Samsung U28D590D only supports HDMI 1.4 (https://www.samsung.com/uk/monitors/uhd-ud590/). And its successor U28E590D does support HDMI 2.0 on HDMI2, but has a issue with NUC7PJYH - does not show BIOS.

               

              So, I find this "Compatibility list for 4K televisions" completely useless and misleading.

               

              Regards,
              Peter

                  Thank you for your patience.
                  We have provided your feedback, which is much appreciated, to the appropriate team so more models can be included in the Intel® Product Compatibility Tool for this unit.
                  We wanted to communicate that the Intel® Product Compatibility Tool is not meant to be exclusively for "4K Televisions" but rather "Televisions" so it is expected to find non-4K TVs there.

                    Hello Diego Sanchez Campos,

                     

                    Here I am speaking about HDMI 2.0 support. The Product Compatibility Tool does not say anything about HDMI 2.0 (or even 4K) compatibility.  So you can mention all the TVs I tried as "Compatible" since they work fine with HDMI 2.0 disabled (4K-30Hz).  But I'd call that cheating, since NUC7PJYH is claimed to support HDMI 2.0. 

                     

                    My point is: as a part of "Intel Validation" procedure it would be good to check HDMI 2.0 compatibility for the TVs which support it. Otherwise, such list would remain, like I said, completely useless and misleading.

                     

                    Best,
                    Peter

                      It would be great if the validation process would be disclosed. What has the TV be able to do in order to get on that list?

                        Peter you have several threads open about this issue so I'm not sure which one you want to focus on.

                         

                        My recommendation is that we use this thread Re: NUC7PJYH - No signal on Samsung 4K TV when HDMI UHD Color is ON and I will close this one. 

                         

                        Does that work for you?

                          PeterNUC

                          cvare,

                           

                          In this thread I am trying to find a (preferably, budget and available on the market) 4K TV, which could be used as a monitor for NUC7PJYH (at 60Hz with 4:4:4). So far I could not find a TV, reasonably compatible with this (and, I believe, not only this) NUC. So the search is not over yet, and I do not see how closing this thread could help anyone.

                           

                          Besides, it is addressed primarily to users who have used or plan to use a 4K TV as a monitor with their NUCs.  I'm just hoping to find a compatible TV and share such info with other. Or, maybe someone else would stumble upon a compatible TV and let us a know.  So, Intel engineers can ignore this thread if they wish to.

                           

                          The other thread Re: NUC7PJYH - No signal on Samsung 4K TV when HDMI UHD Color is ON focuses on Samsung TVs. Since NUC7PJYH is completely incompatible with Samsung TVs at HDMI 2.0 this problem requires special attention from Intel. For example I still cannot use my Samsung TV with NUC7PJYH at 60Hz, which is sad.

                           

                          Anyway, I do not quite understand what is meant by closing the thread. As I see it now, the correct answer to the question "What is a reasonably HDMI 2.0 compatible TV?"  would be "Does not exist".
