I haven't noticed anything of the sort on an E173FP 17".

Sorry, not for me. Mine don't really dim when looking at it from the side either. It's sort of just slightly more white-washed. I'm not sure how to describe it. I think it's just the light emitting from the monitor that doesn't effect its clarity when viewing straight on. Anyway, from the side it doesn't look anything like something I should worry about.

I'm pretty sure that's also how the 24" widescreen at home looks too, so that's two votes for no yellow tint.

Looks like Dell still has some pretty good prices going on the LCDs, when you use the coupon codes properly:
