on my new iMac 16GB ram, I8 and 1TB SSD I currently have a dell 24 inch 4k monitor. If I wanted to have a second monitor for looking at pictures and videos (just sorting albums from the Apple photo app) alongside the smaller 24 inch monitor, is that something that can/should easily be done and if so would I have any scaling problems? Would only need text on the 24 and might use a 27 or 32 for pics to stay open... Would I need a iGPU for this? It’s not going to be professional work or edited etc. Is the only drawback it looks funny with diffeeent sizes? Anyone currently using this setup? Any feedback or pics?
