i have an IPS screen at the moment that is suppoosed to be on par with the LG's using same boards. Im not sure they are actually as detailed as the mac screens.
The dells are probably worth looking at, 24" isn't big enough i am affraid i will be looking at 27"+
I have an IPS panel at the moment so aware of the differences just wanted to see what real people have and how they work for them
Have you tried calibrating the screen with a proper external calibrator?
Yes I have and I still want more+1 for that option. Try calibrating with a colorimeter first.
