I just got the 24 inch Dell monitor (UP2414Q) -- its very nice. I've used other 24" Dell IPS monitors before this.
Works fine via thunderbolt and HDMI with my MBP/Retina -- as in the display is recognized and resolution detected correctly. The problem though is with 10.9.2 the OS doesn't do scaling in the way it does with the laptop's Retina display, so fonts in windows etc are too small (not a problem with the 32" I'm sure). I read somewhere that 10.9.3 will have support to scale external monitors, so I'm looking forward to that.
Photos look amazing on this monitor -- no more pixelation etc. Just like a bigger Retina display.
Also, I'm amazed to see that windows 8.1 handles the monitor (and scales it) better than OS X -- driving it from my Dell m3800 nicely. And LR works great -- didn't realized Adobe had finally updated it to work with ultra high-resoln monitors.
the $1000-$1300 24" UHD Dell is IPS with 8bit + 2bit FRC and the $3000 32" Dell is at least 8bit
the 28" sub $1000 monitors, some of those might be 6bits and I think all are TN panels, but as I mention above it's not just the sub $1000 or the 10k+ with nothing inbetween
NEC has some arriving this year too
