Many years I used the Sony Bravia KDL-40V5500 for my TV watching and gaming in 1080p. I still use it for my retro gaming.
While the Xbox One X and PlayStation 4 Pro have 4K capabilities, sort of, I decided to buy a 4K TV for the Xbox Series X and PS5.
Connections:
HDMI 1: Sony PlayStation 4 Pro
HDMI 2: Nvidia Shield TV
HDMI 3: Microsoft Xbox Series X
HDMI 4: PC with Nvidia GTX1080
