I just got a 22" Sceptre LCD monitor to use with my G4 laptop. I have both monitor profiles set to "color LCD" and Photoshop is set to the same.
The problem is that colors seem washed out on the bigger screen when viewing images in PS. The brightness is all the way down and the contrast is all the way up. I have fiddled with both as well as the RGB balancing in the new monitor to no avail. Images still look better on the G4. More contrasty with richer colors.
Perhaps I have had crappy colors with my G4(old, not very bright display when compared to newer models) and have adapted my working to them in PS. Perhaps the new monitor is more on point but I cant see it cause my eye is used to the G4...
A pal of mine said he has access to one of those color calibrators you hook up to your monitors. I suppose this may be a solution.
