I just purchased the Dell UltraSharp U2913WM 29-Inch Ultra Widescreen LED-Lit Monitor to go along side my Acer R240HY bidx 23.8-Inch IPS HDMI DVI VGA (1920 x 1080) Widescreen Monitor. I am looking at getting a dual monitor arm for them. Will a monitor arm that supports up to two 27inch monitors work with both of my monitors, such as the Mount-It! MI-725 Dual Arm Adjustable Computer Monitor Desk Mount Stand for Two LCD Flat Screen Monitors. Will my two monitors fit, becuase one is a 29inch and the other is a 24inch, theoretically its the same amount of monitor as two 27inch monitors.
