Are there any issues with driver support for 8k that will affect purchase choice?

I recently bought an 8k TV (which is not brutally expensive when refurbished) and want to connect my workstation to it. I went through the list of video cards from my local store and the cheapest that claims 8k support is the Gigabyte RX 6400.

Is a Gigabyte RX 6400 Eagle 4G a good video card for mostly text output at 8k resolution? I might do things like play Netflix in 1/4 of the screen and have text in the other 3/4. Definitely nothing at all challenging in terms of video. AMD drivers have a history of being reliable, but will I face some issues like lack of HDMI support for 8k?

I’ve watched a YouTube video about trying this on Windows and they got frame rates as low as 4 FPS for games which is not a concern for me. It definitely works OK with Windows driving the card. Will I be likely to have issues running the same hardware on Linux?

    That card has DisplayPort 1.4 which means that if HDMI doesn’t work then it’s limited to HBR3 which gives 24bpp@31Hz, which is barely adequate.

    Also how do you set the bpp rates? The DisplayPort wikipedia page says that 24bpp and 30bpp are supported, but how do I even know which is in use?

      Ah yes, did mess up looking at the specs table for bitrate modes. Correcting root comment for anyone else who views this thread.
