I have a 22″ Dell widescreen monitor. I had been using it for some time but then one day flipped it to portrait mode. It makes so much more sense this way! Web pages and news documents (and e-mail) are all really long and don’t fit that well on a widescreen.
Sorry to be a bit off topic here, but I have had good luck with Dell monitors in the past, but just wanted to encourage you to think about trying it in portrait mode if your monitor has the swivel capability.
