I just purchased a 13.5" Microsoft Surface Book, and am looking at buying a monitor in next month or so.
My primary use of Monitor would be for photo editing with Lightroom, DXO, Topaz Studio etc. And general web browsing.
And of course the extra real estate will come in handy. :)
I do not do gaming at all.
Preferences are for around a 27" screen, budget $500ish.
Do I need a 4k screen?
Hope that's enough info for starters.
