Flatscreen displays have a native resolution that yields the best quality image, and that's what you'll want to use for the crispest picture, especially text. To get significantly more tracks onscreen, you'd probably have to replace the monitors with larger ones with a higher native resolution.
Another possibility is rotatable displays. Mine can be rotated 90 degrees, which reverses the width and height dimensions so that you can see more tracks in the track view (but fewer in the console view). It has an added advantage of not blocking your speakers as much. I've tried working that way, but found I preferred seeing more of the track over more tracks.
Track folders and screensets are probably your best (certainly the cheapest) strategy.
