I decided on Dell’s new IPS monitor U2412M. I’ll get it tomorrow for 272 Euros. I have a question though (and don’t know where else to ask): I’ll connect this monitor to my laptop which has a HDMI out (monitor only has DVI in so I also bought a DVI-HDMI cable adaptor). Anyway, the question is: My laptop screen resolution is 1600x900 and my new monitor’s resolution is 1920x1200. What would be the quickest and simplest way to change the resolution and wallpaper when connecting the external monitor (and vice-versa when I unplug it)? Is there any such application or a tool already built in Windows 7? Or do I have to do it manually each and every time?
