Anyone using UltraWide displays? How do you like them? Any issues with apps or scaling? I'm a screen real estate junkie. While CPU horsepower is important, I personally find that being able to work with lots of windows open boost my productivity the most. I currently have three 27" 2.5k displays, which I've had for a while now (27 iMac and 2 Dell U2713HM). For me, this works. Center display is production, Right is for communications, and Left is for consumption). Though I'm currently using a late 2012 iMac, I did briefly try a 5k. While the 5k was beautiful, I didn't find that it would help me with work productivity much. Yes, it was better for photos and perhaps video, but that's not really how I pay my bills (probably 5% or less of my work). But looking at some of the ultrawides has me salivating. I'm talking about the 3440x1440 models like the Dell UltraSharp U3415W. My thought is that, when I get my next 5k iMac, I replace one screen with the ultra wide, and eventually 2 of them. I still plan too have the 5k in the middle for work & personal stuff where accurate image rendering is important. Anyone currently using a 3440x1440? Anyone use one with a 5k iMac? If so, how do they match up? Anyone figure out how to get one to work with an old iMac (my late 2012 says max external is 2560x1440) Any feedback on particular models of display? I'm looking at the Dell UltraSharp U3415W Thanks!
