Samsung monitor settings

Hi, I have a Samsung Odyssey G6 27” that I use my ps5 on. I feel like the picture is so bad. Specially on things away it seems distorted and it just looks like over all crap. I tried looking for settings. I couldn’t find a good video can maybe someone help me out with either good settings for the monitor or the ps5. Monitor cost $600 so I would like it to at least look decent. Is it my HDMI cord for my PS5?
