Best monitor setup for rendering window

So I use Rhino and V-Ray. I also use Grasshopper a lot and I get really annoyed with overlapping windows. The issue is that I use a 5k 27 inch Ultrafine on my PC via Tb3 card. Its crazy bright and sharp and Rhino scales very well in 5k. I just cant run dual 5k monitors on my PC because the card won’t support it. I could get 2x 24 inch Ultrafine monitors and keep Grasshopper or rendered viewport in the second one.

Anyone have advice on this? Does a dual monitor really help? Even if each monitor will be smaller…

Maybe a 13 inch iPad pro with Duet Display
