A Raspberry Pi with the stock OS, Raspbian, has a lot of different configuration options that are found in the config.txt file in the boot directory. While included raspi-config utility can help with some of these settings, it leaves a lot of possible options out. Enter PiCon, a Java-based configuration utility written by Raspberry Pi forum member avatar1337. The utility lets you fine tune your display and hardware settings to meet your exact needs. The cross-platform application saves a config.txt which you can upload to your Pi. On your next reboot, the settings should be applied.
