Hey,
What is the best TV I can buy for £600 or less which is at least 49 inches and suitable for playing emulated games. Should I be looking for a 4k 10 bit hdr?
I would consider increasing my budget to £800 if necessary.
I am in the UK.
Thank you very much.

your question is mostly "What TV should I buy for x mount of money"

For emulation, does it output color at some sort of resolution? Yes? Great, it works for emulation.
