I am looking to switch out 2 x Dell U2414H 1920 x 1080 connected to the surface dock for single larger higher resolution monitor. Current arrangement works - but continuously having to log in/out to get the external monitors to scale to 100% when docking and putting up with scaling and slight loss of sharpness on the SP3 when docked is annoying. I am on Windows 10 and I need the SP3 to run at 150% so my 50 year old eyes can see it. I want to avoid any of the scaling annoyances I am currently putting up with. Ideally something larger than 30" and maybe curved. Needs to be something that I can dock and it will look great without any fiddling. So what should I be looking for when choosing a single large external monitor?
