    HD Graphics 500 can't do UHD 60hz 4:4:4

    Stefan75

      Hi

       

      I can do UHD 60hz 4:2:2 on my Philips 43PUS6101/12 (HDMI set to 4:2:2/4:4:4).

      But I can't get the HD Graphics to do UHD 60Hz 4:4:4 8bit.

      Currently it's in 32bit mode (=10bit, right?)... so that would be over HDMI 2 Spec (UHD 60Hz 4:4:4 10bit not possible).

      So where is the 24/32 bit pulldown, or how can I force 4:4:4?

          Hello :

           

          In regard to your inquiry, according to the datasheet of the Intel® J3455, in order to be able to get 4K 4096 x 2160 resolution to use the display port cable is needed, on the following link you will be able to confirm that information and also see the resolution supported by the processor, page 12:

           

          http://www.intel.com/content/www/us/en/processors/pentium/pentium-celeron-n-series-j-series-datasheet-vol-1.html

           

          When using the HDMI port the max resolution is the one that is currently working: 3840 x 2160.

           

           

          Just to clarify the previous information, UHD is actually 3840 x 2160, and 4K is 4096 x 2160.

           

           

          Also, 32 bit mode is 8 bit.

           

           

          You will be able to set 3840x2160@60hz 8bpp (8-bit) with D.P 1.2. In order to find out if 4:4:4 can be used we just need to check a few details:

           

           

          How are you testing or confirm that the display mode is not using 4:4:4?

           

           

          Which application are you using?

           

           

          What is the video codec?

           

          Is the Chroma 4:4:4 Changing to another chroma subsampling during playback?

           

          Any further questions, please let me know.

           

          Regards

            Hi Alberto

             

            This is the mainboard: ASRock > J3455-ITX , I bought it for the 4k@60Hz and HEVC decoding feature. There is a display port to HDMI converter onboard: http://www.megachips.com/products/Data_Brief/MCDP28x0_Databrief.pdf

             

            In the TV manual I found/set this: "The setting UHD 4:4:4/4:2:2 allows UHD YCbCr 4:4:4 / 4:2:2 signals. The setting UHD 4:2:0 allows UHD YCbCr 4:2:0 signals."

             

            I can see that the chroma is 4:2:2 with various chroma test patterns. I also set up an extended desktop (HDMI UHD TV and DVI FullHD monitor), sliding windows or test patterns between the screens showed me the difference between 4:2:2 and 4:4:4 (red/blue was strong/correct and fonts were more readable).

             

            I also tried multiple HDMI cables (including certified Club3D 4k@60Hz), no difference.

             

            Can the HD graphics 500 do YCbCr 4:4:4? If yes how/why would it automaticaly decide to use it? Can you tell me the logic of the driver/control panel (preference RGB/YCbCr, chroma)?

             

            Unfortunately I couldn't find any windows tools that show the current output mode... I really wish the HD graphics control panel had more clear settings (RGB/YCbCr+chroma+bpp) and show more information (for advanced users)!

             

            Regards

            Stefan

              Hello Stefan,

               

              For HEVC video decoding, the HD Graphics 500 is limited to Main Profile 10, which allows a bit depth of 8-bits to 10-bits per sample with 4:2:0 chroma sampling. See Intel® Pentium® and Celeron® Processor N and J Series: Datasheet 1  (page 69).

               

              As you probably already know, this GPU only offers support for DisplayPort 1.2 and HDMI 1.4a, thus the chip on your motherboard is doing the physical conversion from DP 1.2 to HDMI 2.0. For other non-video playback results, I would suggest contacting your motherboard manufacturer. This is primarily because the LSPCON is not an Intel component, thus we cannot confirm or test its full functionality when paired with our GPU.

               

              I hope this information helps.

                Today I was able to test this mainboard with 4 other UHD displays.

                On 1 TV nothing, 2 TVs UHD 60Hz 4:2:2 and the monitor only UHD 30Hz 4:2:2.

                 

                I'll have a talk with ASRock about the LSPCON chip.

                 

                Thanks for all of your help.

                 

                P.S. would still love to see the actual output info in the HD graphics control panel

                would help debugging if I knew what the DP is outputing...

                  We actually opened a thread in which we want to collect user feedback on the options in the Graphics Control Panel.

                   

                  Advanced users - we need your feedback: Control Panel color configuration options

                   

                  You can reply to that one with your feedback (features request, screen shots, etc.)

                   

                  Hopefully with sufficient feedback from our customers we can push for changes!

                    Hi Roland, I've been doing more tests and research, but have more questions..

                    Would the LSPCON be connected to the eDP or DP output of the N/J processors if it's onboard?

                    And what is the max pixel clock, 300 or 600MHz?

                     

                    In Ubuntu 16.10 I see the following X log:

                    What do you think the "HDMI max TMDS frequency 300000KHz" means, is it the N/J CPU HDMI 1.4 out?

                    Or is it maybe the limit of my HDMI TV, seen through the LSPCON?

                      Hello Stefan75,

                       

                      To answer your questions:

                      1. Would the LSPCON be connected to the eDP or DP output of the N/J processors if it's onboard?

                      Answer: The LSPCon is always connected to DP.

                       

                      2. What is the max pixel clock, 300 or 600MHz?

                      Answer: Max pixel clock is 600MHz on HDMI 2.0.

                       

                      3. What do you think the "HDMI max TMDS frequency 300000KHz" means, is it the N/J CPU HDMI 1.4 out?

                      Answer: this message either indicates the GPU’s max limit or a block in the monitor EDID indicating that limit.  Neither one makes much sense here.  With LSPCON the GPU uses DP signaling, not TMDS.  And the monitor is exposing a 4k60 timing, which innately requires >300MHz frequency.  If Ubuntu understands our DP++ port can switch to TMDS signaling, then in that case maybe the 300MHz timing is reflecting the native HDMI port capability rather than DP or monitor capability.

                       

                      I hope this information helps.

                          I've done more 4:4:4 testing...

                          • TV internal media player, failed
                          • Oppo UDP 203 4k player (set to 8bit RGB or YCrCb4:4:4), failed
                          • PC with GTX 960 HDMI 2 (set to 8bit RGB or YCrCb4:4:4), failed

                          ...so it looks like the HD500/driver is actually ouputing 4:4:4, but my TV can't display it correctly.

                           

                          I guess I'll have a chat with Philips support.

                              I could check some Samsung TVs today. First I tried a UE43KU6070, but it didn't show any picture at all... strange.

                              Then I connected a UE48JU7580, after enabling 'HDMI UHD Color' and changing the HDMI input type to 'PC' I finally got 4:4:4.

                              So actually the HD 500 can do UHD 60Hz 4:4:4 8bit...

                              I guess I bought the wrong TV (Philips).

                                Hello:

                                Thank you very much for letting us know the resolution of this problem and for confirming that the Intel® HD Graphics 500 does support 4:4:4.

                                It is great to hear that you were able to finally get 4:4:4 and that the reason why it was not working before was because of the TV not supporting that feature.

                                Any other inquiry, do not hesitate in contact us again.

                                Regards

                                Alberto
