Im using a Samsung 40in 4K (UN40KU6300) as my monitor with my PC using HDMI.. I know it its an older TV but.. I just upgraded my computer to a Mac mini M4 and I noticed the monitor just doesn't look good using Facebook or social media some (a lot) of the photos look kinda dark but other things look great and movies and videos look good.. it did it with my PC also.. So I am wanting to upgrade to a new monitor.. I do not play games all I use it for is Photo Editing and some iMovie stuff and numbers (Excel) social media and YouTube.. I was looking at the Samsung Neo G7 43in or the Samsung M70D both are right around the same price .. Your Thoughts? or keep old one. I want to stay around the 500 or so budget
