Dell not working out for you, or?
I want to personally aim for monitors above 1080p resolution as I've become picky after getting used to the lack of seeing pixels on my Macbook Pro LCD (2880x1800) resolution. However I would like to try out a large 4k monitor in person but there aren't many stores around Vancouver that don't have flickering lights, defeating the purpose of trying one 🙁
I'm mainly concerned about the DPI scaling. I know under OS X it's quite good but unsure of how it works under Debian.
