Custom screen resolution for 7″ touchpanel

As HMI for the home automation over IP project I’m using a 7″ touchscreen. To get the best result from the screen I want to use it on it’s hardware resolution. This is 800×480 px, not a standard supported resolution. To get around the problem I installed Powerstrip, a very useful program to create custom timings and resolutions. After experimenting for a few minutes I had the touchpanel going at 800×480 px. Another job well done…
