I did this for a bit with a Q900R, a 65in 8k TV - a upside or downside depending on the time of year and climate is that it uses a lot of power and generates a good amount of heat.

Here’s a review of the series - https://www.rtings.com/tv/reviews/samsung/q900-q900r-8k-qled

One interesting thing is that it’s been firmware updated to support hdmi 2.1 on all hdmi ports now.
