I connected my new PS4 pro to my TV and my laptop display through another HDMI port changed?

Apr 10, 2018
Hi there.

I always have my Lenovo laptop plugged into my TV through an HDMI cable and stream everything I watch through that. I have just brought a PS4 pro and plugged it into my TV and this has changed the resolution that is displayed on the channel that my laptop runs through? It kind of made the windows screen a bit more zoomed in and fuzzy on my TV screen. Is there any reason why this is and how I could correct it? Sorry if this isn't explained well.

Thank you, Danielle.
