Er, are they good? I have a gorgeous Dell IPS 4k monitor at work and (I know, it's very silly) I actually get a tiny thrill whenever I pop my IDE open in it. It's just so darn pretty.
Sitting in front of a Dell 4k monitor and having used a good 4k monitor I am would not call Dell's offering good.
I have never used an Apple monitor, but I have used several other 4k monitors and they are great. My Dell monitor is just fraught with compatibility issues and needs special software to work with win 7. I use Ubuntu and it barely works there, my coworkers have to treat theirs like special snowflakes.
I think I communicated that poorly. I only need to use win 7 every 3 months when I change my domain password. I don't need a 4k monitor for that, so I go without.
On Ubuntu the monitor needed much finagling to get working right, unlike my AOC or Asus 4k monitors which both worked when hotplugged using HDMI.
My coworkers, who aren't all devs, have more work to do in windows and they needed the special software.
How odd, maybe I'm just quite lucky then. To be fair I'm not doing any sort of dual-monitor setup. I just forgo my laptop screen entirely (close the lid) because I've found the one 4k to be plenty. Maybe if I started getting more complicated than that, things would get weird.
