I use 5 LCDs on a regular basis: A 19" Sony on my business computer, dual 19" BenQs on my edit system and dual 17" Samsungs on my wifes' edit system. Never a problem.
LCDs do perform at ther best hen they're used at the native resolution, and if I'm retouching photos I use a CRT. But darkness? Sounds like there's a problem somewhere.
Can you swap in another on the Packard Bell or try this new LCD on a different system?
I prefer LCDs not only for space saving: They also use less electricity and generate less heat...(not inconsequential in the summer when all the equipment is on and we have all the A/Cs cranked!). I also find them easier in the eyes for extended periods.
