QLED 8K Q900R and Q950 TV tread (software/firmware updates, One Connect Box swap, HDMI 2.1, etc.)


Hello everyone,

I have a QLED 8K Q900RA TV, bought in October 2019 (from - a shop in Norway), and got a new One Connect Box replacement to fix the lack of HDMI 2.1 (only in port 4) in May 2020 (shipped free of charge, after having to wait a few months). I got a free Galaxy S10E 128GB phone (no longer valid), plus 10 years burn-in screen guarantee (had to register online right after purchase).


As far as I know, there are three different models: Q900RA (2018), Q900RB (2019) and Q950R (2019) - all three came in different screen sizes.

Special mentioning of the HDMI 2.1 port upgrade promise of the Q900RA (2018) on its product page:

The purpose of this tread is to keep track of problems and solutions our TV might have/get, One Connect Box swap, software- and firmware updates, etc.

Known problems:


- One  Connect Box of the Q900RA (2018 models) lacks the HDMI 2.1 - but it has been fixed by the One Connect Box swap (contact Samsung), note the HDMI 2.1 is only in port 4. The 2019 models should have the HDMI 2.1 (no OCB swap needed)
- Lack of eARC

- Lack of AV1 codec (needed for YouTube 8K compressed play)

- Possible a problem with the YouTube app on the TV when running 1440 and 4K videos (on the TV's web browser 4K on YouTube works flawlessly !)


@Humorsopa I am not specifically saying that the update I referred to will help for the 4K120Hz (or the eARC or HDMI 2.1)... I am asking if the issue of the 4K120Hz. will be fixed (meaning: not excluded for a future fix) for the Q900RA TV, as he only mentioned the 2019 and 2020 models.


Patrik, I don't own the 2018 Q900RA 8K model. I have the 2019 and 2020 8K:s. But no, not anyone in the group, and there are many, can make anything happen with HDMI 2.1 on the latest firmware. They are getting very frustrated, and rightfully so, since all of them have gotten a new OCB from Samsung in order to make HDMI 2.1 work.


And we are all very frustrated also of course since neither eARC works on any of the 2018-2019 models.


So, 2019 HDMI works fine. 2018, not at all. Not about flickering, it doesn't work in any way. 


Hi Patrik, I have the problem with Xbox 120hz and 2018 q900rat in the uk. See attached photo I have latest firmware on tv from Samsung.comas of last week



Hi Patrik my Q900ra is a 2018 model is the firmware fix available for this model yet? Thanks
