Firstly, the propaganda you hear about Dell isn't all true. Their panels are beautiful, for a fact. Of course some of their models suffer issues, mainly blacklight bleeding problems. Despite the countless criticisms I received when I decided to buy a Dell 20" widescreen panel, I still went ahead and got it.
It was awesome! And still is! The quality is amazing and gaming is excellent too.
Regarding monitors over 19", sure they're necessary. If you take a look at the resolution increase from 17" lcds to 19" in general, you'll actually see that there is none. To me, playing 1280 x 1024 on a 17" is 'just about right'., and that's the max you can go. On a 19" I don't really like it anymore, and I can't increase it any further than that same resolution. It's not until you go above 19" that you can start to increase. But this is just a personal opinion. 1680 x 1050 is very nice on my panel.
So all in all, the Dell panels are overal very nice. The problem isn't with the technology in the panels, it's with Dell's quality control. But really, it's not as bad as people make it sound.
