But now I'm troubling with the screen being to big for my tv. So I googled some more and found out I had to change the config.txt file on the SD card. The original contents where like this:
I learned that I could set the different overscan values (left, right, top, bottom) to solve this problem. So I changed the config.txt file to this:
arm_freq=800 overscan_left=64 overscan_right=64 overscan_top=64 overscan_bottom=64
But now the Raspberry Pi doesn't recognize the SD card anymore. And when I change it back to a single line it works, but it doesn't do anything with the overscan values. So my idea is that it has to be something with the line breaks in the file. I'm using Windows 7 and Notepad to change the config.txt file.
How can I fix this problem?
