Looking for a monitor upgrade!

Hello,

I am looking to upgrade my monitor and was looking at OLED as the next step! I am not that technically minded when it comes to monitors and specs so I was looking to see if anyone had any recommendations!

Right now i primarily play on PS5 but I am looking to get into PC gaming around next year.

The 2 monitors I have looked at are :

LG UltraGear 27GS95QE-B

ASUS ROG Swift PG27AQDM

Both of these monitors are 1440p but I am a little confused with the hdmi 2.0/2.1. The LG has a 2.0 and the Asus has a 2.1. My question is does this really matter for the PS5? Will I still be able to get the same out of both monitors? I read earlier that 2.0 limits you to 60hz on PS5 and I am not sure whether this is true or not.

Another thing i have read about is matte or gloss? I am not really sure what this means so if there is any insight anyone has that would be great.

Any help on this or any other recommendations for me would be greatly appreciated!
