At first I thought my Ci20 was not working. Booting from the NAND image I received no image on the monitor. However, I noticed the ethernet port was active. I re-flashed the NAND with the debian7_2015_02_02.img file that I wrote to an SD card. I still got no image on the monitor. I plugged the Ci20 into my TV and got an image that needed overscan adjustment.
What can I do to get the Ci20 to output a lower resolution that will display on my monitor?
