    I think it's time to start an explicit thread for/about [email protected](FPS)...



    PCB: TRN6A_V1.0 (HPH NT-V6 by Nagrace, UT3 by Ugoos)

    Because of the 'HDMI IN' which the RK3288 doesn't know, the PCB have to use a HDMI-Switch-Chip (Lontium LT8641SX) which is 'only' able to support HDMI version 1.4 which only supports [email protected]....

    PCB: Netxeon (Tronsmart R28, UBOX R89, Beelink R89)

    Hi,

    I just got my R89 Beelink few days ago, so I soon updated with the 111k4110_1219 firmware.
    I connected this one on port 1 of my screen TV TCL LED U40S7606DS 4K UHD
    But this is what I see when going to screen setting on the R89 beelink:
    :
    Very disappointed, I thought I could use the 60Hz but it is not available only 30Hz is available from the menu when I'm using HDMI 2.0 ports on both sides.

    Is there someone who already met you the same worries?
    Or is there same problem on a different 4K screen model with HDMI 2.0 port ?

    Thank you for your help

    I think its to do with the color depth? A lot of TV's today only do 4k,60hz (HDMI 2.0 lite, almost) at an 8bit colour depth. The RK3288 does 4k 60hz at a 10bit colour depth. This means an 8bit HDMI 2.0 TV would not work at 4k,60hz receiving a signal from an R89 which has 10bit depth. Most TV's now and in the future will have HDMI 2.0 with 10bit colour chips and most HDMI 2.0 devices such as 4k blu ray's will output in 10bit colour.
    This seems to be one of the problems with being an early 4k TV buyer, you don't see what's coming out in the future and end up with a TV that is virtually obsolete when 4k becomes mainstream and is standardised.

    PS,4k @30hz is horrible with screen tearing and poor performance.

    Is this a dream or an update can bring this support in the future?

My TV only has 4k60hz 8bit and does not show 4k60hz support on the Beelink box. If your TV does not have 10bit support then it cannot be updated by software as the 8 or 10bit chip is hardwired into the TV motherboard. I'm not sure if the Rk3288 can be updated with software to support 8bit 4k60hz but I don't think it can.

    Manufacturers need to make people more aware of this as I only found out by doing quite a few hours of research.

    It has been some discussion about the HDMI 2.0 vs. 1.4 in this thread –
    Today I google translated a french Review, with a interested part that puts some light on it:
    "I still wanted to make sure of the presence of a true HDMI 2.0 interface, and actually, I find two HDMI 2.0 interfaces Silicon Image Sil9679, able to manage 4-60 im / s 4:4:4 and 10 bits, but also 12-bit 4K 24p, 3D 1080-60 im / sec 1080p 120 im / s. Each interface allows only one HDMU connector, we found two assigned to the HDMI 1 and 2, but there is also a HDMI 1.4 interface assigned to connectors 3 and 4. Clearly, it will therefore focus connectors 1 and 2 for 4K."
    (the text is google translated!)

    What is interesting is that, if the same chip is on the samsung which has an option per manual/menu to activate "uhd color" 4:2:2 and 4:4:4 then:
    1- samsung does not really have hardware capability and is simply downsampling or
    2 - both sony and samsung can do it, but sony has not enabled via software yet

    Maybe a solution at a Sumsung TV (HU7250) ???

    Maybe a solution which I found at another forum and seens to be more the TV than the box:
    I was able to get it to work with the Samsung UN50HU6950. It initially didn't, but it worked once I toggled the UHD color inside the TV options menu

    I found the solution to my problem in a different forum that doesn't involve having to move TVs around. In setting Picture > Picture Options > HDMI UHD Color > Slect whatever HDMI port your box is using > Follow onscreen instructions. Done!



    You are welcome to post

      TV is the LG 55UB820V. HDMI inputs listed as HDMI 2.0 [email protected] In the manual, it says all 3 HDMI inputs are 8bit colour only. With the Beelink R89 i get no option for [email protected],only [email protected] I've tried 3 different HDMI 2.0 cables and colour options in TV settings etc. Latest stock ROM used on R89. Only other conclusions are that after looking at the Open Chameleon website info, 8bit colour is not supported for [email protected] on the Rk3288.

          The LG55UB850V has an HDMI port which supports 40k at 60hz with 10bit colour. Do you have it plugged into HDMI port 3? If so then that's the port that supports 10bit colour. My cheaper LG model only has 8bit on all HDMI ports and does not work at all with [email protected]

              The other thing to be aware of is that HDMI 2.0 introduced a 4:2:0 YCrCb chroma subsampling mode for 4K. (4:2:0 is the standard chroma subsampling for Blu-ray, DVB/ATSC/ISDB broadcasting etc.)

              It just so happens that 2160/60p 4:2:0 8bit can JUST squeeze into the bandwidth of an HDMI 1.4a connection - allowing HDMI 1.4 interface chipsets to be used and classed as HDMI 2.0 (*)

              You will find quite a few 4K UHD TVs on the market now sold with HDMI 2.0 inputs that will only accept 2160/60p or 50p at 4:2:0 8 bit, whilst they will accept 4:2:2 and 4:4:4 at 2160/30p or less... Some Sony Bravia sets for example.

              Given that UHD1 broadcasts are likely to be 2160/50p or 60p 4:2:0 (though possibly at 10 bits) this isn't a major issue for TV viewing, however it does mean that if you use your TV as a display for photos, Windows etc. and run at 50/60p 4K you will have subsampled chroma - i.e. lower resolution colour information.

              (*) And that is how nVidia added 2160/50p and 60p support to their HDMI 1.4a Kepler and Maxwell cards with a driver update. (The card can do 2160/50p and 60p - and by using 4:2:0 they can get an HDMI 1.4 interface to carry it)

                My rom for The veolo 4k and also a rk3288 board has 4k/60 fps enabled.

                Did not test it i don't own a 4k tv with hdmi 2.0

                http://www.freaktab.com/showthread.p...423#post278423

                You can try it on most rk3288 boards i think.

                  No 4k on my TV

                  I have a Toshiba 58L9363DF (similar to 58M9363 and 59L9300) 4K with SW-version: 7.11.80.35.05.1 - 0211 wich support HDMI 2.0 (don't know if it's 8 or 10 bits)

                  Sadly my RKM MK902II only shows [email protected]

                  my PC with GeForce GTX 970 works at [email protected]

                    I'd guess if the Rk3288 is showing only [email protected] then it's an 8bit hdmi port. The PC may have [email protected] 8bit drivers.

                    The only way to tell would be to find the hdmi specs for your TV.
