After my xbox360 console I decided to buy something new. An Xbox series x. But my TV is old! It's thick and not even 8k or 4k. It may have 1080p (I'm not sure) What should I do? Not buying the upcoming console? A new television would then be too expensive
Now have the xbox one x and a tv that is about 10 years old. Couldn't complain, great resolution and no other problems
You won't have good quality with an old TV. You definitely need a good TV for new consoles
Define "good TV".
For me a normal 1080p TV would be enough. Although there are already extremely cheap UHD televisions.
