My employer is planning on supplementing our team's existing non-Dell laptops with external LCD displays. I'd like to recommend Dell, if some kind folks can help me figure out the proper currently-available models.

For starters, the displays must be either 17" or 19" LCDs. They will be used exclusively for office applications, so variables related to video quality are of little or no importance. Likewise, we need no multimedia features - no built-in speakers, or anything like that. We want to keep prices down as much as possible.

We would GREATLY appreciate the ability to rotate the display 90 degrees to work on documents in portrait orientation. I brought in a spare Dell display (from home) with this feature, and it works beautifully.  I suppose I'd even call this a "required feature."  Unfortunately, Dell's descriptions don't seem to mention this perk.

If anyone can provide me with a few searchable current model numbers, I would greatly appreciate it.

Thanks.
