Up until I got my new 2015 15" MBPr(AMD), my highest resolution on a monitor was the Dell 24" 1920x1200 display. My mac's retina display is starting to make that "Full HD" look a little shabby but I'm living with it. However, I need more real estate on my external display so am in the market for a new larger display. Considering the three displays listed in the title. The BenQ 32" 4k, Dell 27"4K and Benq 32" QHD monitors are currently $900 (Amazon), $500 (Amazon), and $377 (refurbished through BenQ on ebay). I'd be using this monitor primarily for web development and other coding, and would preferably use my MBP in clamshell mode and rely entirely on the external display. I worry about the Dell 27" 4K because it's not that much bigger than my current Dell, plus all the wake issues everyone's talking about. The Benq 32" 4K is really what I want but that $900 price is super hard to swallow. The BenQ WQHD resolution model seems like the safest play. Tons of real estate in a rock solid product that has great reviews, with none of the "4K headaches" that most of the new displays seem to have. I wonder if the PPI will be a problem though. 2560x1440 at 32" has an even lower PPI than even my current Dell. Bummer. Has anyone here grappled with these issues? Or have experience with two or more of the monitors I'm looking at? Any advice much appreciated.
