After evaluating various screens for my nMP, I ended up choosing the Asus PA279Q. It was one of the screens with consistently high reviews and supports both sRGB and aRGB, was $200 cheaper than the Apple Thunderbolt Display, more current and it has a reasonable response rate so that it shouldn't ghost too much on the occasional game. I received the monitor earlier in the week, before the nMP and used it with my Windows work laptop and was very happy with it. When connecting it to the nMP however when it arrived yesterday, the screen looked horrible. Turns out that OS X doesn't provide an RGB signal over Thunderbolt by default. Therefore, sRGB and aRGB modes were not working over HDMI and DisplayPort connections (didn't try out DVI as I don't have the appropriate cable). In standard mode, the screen looked bad as well. This was fixed by turning off the sharpening on the monitor. But the colours were still a bit too saturated. And I got the screen for its sRGB and aRGB colour accuracy. I started looking for a way to force RGB output via the Thunderbolt port and found this page: http://www.ireckon.net/2013/03/forc...-external-monitor/comment-page-3#comment-9491 I followed the instructions, created a display override profile and am now able to use sRGB and aRGB modes over both HDMI and DisplayPort. When selecting the standard monitor color profile in the OS X display settings, the colours were not saturated enough. This was fixed by selecting the sRGB profile. Now I'm trying to find out if I can get the audio controls to work in OS X, rather than having to rely on the monitor's controls. Not a big issue but it would be more convenient. I was a bit naive in thinking that screen drivers were consistent across OS X and Windows. With reviews pretty much alway focussing on the latter, it's hard to get good information beforehand on recently released screens. But anyway, I hope this information is useful for others with this screen and those who considering to get it.
