There’s no point getting a PS4 Pro or any of the next gen consoles if your telly doesn’t support 4k resolution.
Although to get the best out of games these days I’d implore you to upgrade your telly (if you can stretch it). You’ll need the hardware to go with it as well. I just have to because I get serious FOMO lol.
If you’re content with what you have though, save money and don’t bother with a PS4 Pro or the next gen devices mate.
