Photoshop CS6 with 4k Display [Duplicate Thread LOCKED]

Hello,

I know this topic has been discussed in the past but I'm looking for a bit more information. I've had PS CS6 for for about 8 years now and recently got a 75" display with a native resolution of 3840x2160. As most know, there is an major issue with the UI being too small when running in 3840x2160. My display has 59ppi, and I heard that CS6 was made for 96ppi. I understand that there should not be an issue if the displays ppi is under 96ppi. Which in my case it is.

I just want to confirm a few things. Is running CS6 in 1920x1080 my best option? I know there are a lot of scaling methods out there and maybe that is a better option. Whatever my best option is, does it make sense for me to get a professional camera? I have been of the fence about getting a camera for several years now. I've always wanted one but with the CS6 display issue, it might not make any sense. For example, I was looking at the Canon EOS R5.

PLEASE DO NOT MENTION UPGRAGING TO A SUBSCRIPTION! THIS IS NOT AN OPTION AND NEVER WILL BE! I WOULD NEVER DO THAT EVEN IF I WAS DONG PHOTOGRAPHY AS A BUSINESS, WHICH I'M NOT! 

Thank you,
