I don't know my way around that well. Is 50hz good for gaming and can you play at 60fps? Would also like to use it later for Ps5. I know the Ps5 can be 120fps but 60fps is enough for me and it is much cheaper
TVs are generally not that good for gaming.
I know but I want 43 inches and monitors already cost 1300 euro and a TV only 1/3 of it
You can play at 60 FPS, yes!
However, the monitor only shows 50 FPS because it only has 50 Hz! Since your PS can work to death and produce 500 FPS, you only see 50.
However, the PS4 usually only shows 30 FPS anyway. If you find that fluid, 50 should be enough.
TVs are generally not the yellow of the game! But with 50Hz you can already gamble. It would be too little for me personally, but as a PS4 user (and soon PS5 user) you should be able to play on it!
