Say if I have a 8K60Hz TV what should I do now in order to enjoy the 8K? Sure the 8K TV (Samsung, Sony, LG etc) comes with great 8K upscaling capability.
Let's look at some current hardware and services
1) Handphones
Some already have 8K@30Hz feature like from Samsung, Xiaomi etc. It's rumored that handphones coming next year will support 8K@60Hz. The question is using a USB-C to HDMI2.1 adapter cable connecting from the phone to the TV won't work. The only way out is to copy the 8K video clips from the phone to the PC/laptop and play from there.
The resolutions Smartphone cameras can capture have been rising steadily, and you can now shoot 8K videos with just a smartphone on hand. Here're 3 8K phones that you can buy now in 2021.

To immediately enjoy the use of the 8K@60Hz TV you have to generate your own 8K content or depends on 8K upscaling using the current 4K content
1) Buy a 8K@60Hz camera..........................a very super expensive option. Current prosumer hand-carrying cameras only support 8K@30Hz
2) Get a desktop PC/laptop with the right graphics card and with HDMI 2.1 ports
3) Use cables/adapters which support 8K@60Hz
Handphones and the rest can wait for next year when support for 8K@60Hz is available
