I have a NEC opticlear monitor which is clearly brighter than my secondary Dell monitor(and any other monitor I have used) and I use it for all my editing.(I use the Dell for my various PS menus,etc) It has a setting for AdobeRGB color which matches very well with my printed output(using Moab paper color profiles) so it works great for me.
However, I can't seem to get my Web colors right. Save for Web and ImageReady JPG images are just awful on my monitor.Reds and Blues are dull and dark.I can't tell if it is the monitor or if I'm just doing something odd when I create lower resolution images for the Web.
Take this image

The reds in the original and print are spectacular but here are dull.
