Not sure if I should have put this in this forum or the retail forum - or if anyone else is interested - but it was nice to know for me! Newegg is offering the S24E650BW 24" 1920x1200 monitor for sale for $169.99. I plan to use it as a vert 4:3 (covering up the black bars with a bezel) and it should yield about a 21.3" size if my math is correct. Link:
