Hello, I've received a 3.5 inch TFT LCD today http://www.amazon.co.uk/inch-Digital-Rear-Monitor-Square/dp/B0056WJP1M/ref=sr_1_1?ie=UTF8&qid=1338241039&sr=8-1 and connected it to my raspberri Pi. It works in general, but I have several questions: 1.Is it possible to do something with the refresh rate...
