    NUC5i7 4k - display problems on high end Samsung 65'' TV

    AnnaFrostberger

      Just bought a Samsung UE65KS8005 (like the US 8000 I think) and have connected my NUC5i7RYH to it with a mini HDMI<->HDMI cable. The maximum resolution of this TV is 3840x2160 which is also what is displayed for me. I have downloaded the latest drivers and I am running Win 10. I have 16GB RAM installed.

       

      Here's the problems:

      1. I can't display more than 30Hz (am I even supposed to with this TV:s resolution?)

      2. The display, when pressured with 4k graphics (Youtube & Netflix 4k etc) either blacks out quickly or turns into just noise. To resolve, I disconnect the cable and plug it back into the computer.

      3. 4k problems (as mentioned in #2) are more distinct with Chrome than Internet Explorer, but they do still exist. 4k in Chrome makes the CPU go up like crazy and the fan go wild - then it all blacks/noise out.

      4. If I DO get to view 4k, it is lagging.

      5. Yeah in general, fan/CPU goes crazy.

       

      Now what is the problem? I thought this would be a great computer for purposes like this (that's why I bought it last year) but now with the new TV it seems outdated even though it was high end last year. Blargh!

          Hello, AnnaFrostberger:

           

          Could you please provide me with the your graphics report? Here is how to do it Report for Intel® Graphics Drivers, this will help me gather the information in order to address the issue.

           

          Regards,

          Amy.

            A few things.  One - are you using an HDMI 2.0 cable (18Gbps)?  You need a 2.0 capable cable in order to do 4K/60Hz.  HDMI 1.4 cables can do 4K, but typically max out at 30Hz.

             

            Two - the older processors cannot handle hardware accelerated 4K/60Hz with HEVC 10-bit (most 4K Bluerays use this coding).  Instead the processor has to decode the video, meaning really high CPU.  Even the current Skylake processors in the latest NUCs cannot handle 10-bit HEVC accelerated.  The new Kaby Lake coming out 16Q4 or 17Q1 will be able to hardware accelerate 10-bit, leaving the system to run much cooler.

             

            I bought the Skull Canyon NUC (Skylake) and was caught off guard when it couldn't decode 4K 60Hz 10-bit video files without the CPU pegging to 90-100%.  8-bit or less video decodes and the CPU sits at 5-10% and runs nearly silent.  I'm now waiting for the "Baby Canyon" to come out with Kaby Lake later this year (or early next year).  Then I will have my ultimate HTPC.

                    Hi Amy,

                     

                    Can you confirm (with the help of the driver report provided) whether my NUC unit can handle hardware accelerated 4K or not, like Dewg suggests?

                    I will try another HDMI cable, however the CPU does peg to 100% during 4k playback, both with local and online streamed 4K media.

                     

                    Best Regards,

                    Anna

                      Your processor does include HW acceleration features. In the processor data sheet you can find more details, see here for the file 5th Generation Intel® Core™ Processor Family Datasheet Vol. 1, check page 23.

                       

                      In regard to your first post, 3840x2160@60Hz can be achievable via DisplayPort. You can actually check from your report the supported resolutions along with the refresh rate using the HDMI connection, just refer to the "Supported Modes", and you will the list.

                      There are several issues that can be addressed by updating the driver version, so let's try to do that.
