2.2 Video Output
Overview
I've put some info here on selecting the default video resolution for an rpi on bootup
Based on this link:
Get EDID Info
First to get the edid information
tvservice -d edid
This should result in a file being outputed called edid with information pulled from the monitor
The next command will parse that file and show us a list of supported resolutions
edidparser edid
Change the boot resolution
Next based on the output from before we're now going to change the default output resolution when the rpi boots
nano /boot/config.txt
The two options to watch out for are
hdmi_group=1
hdmi_mode=16
Note:
- CEA = hdmi_group=1
- DMT = hdmi_group=2
The mode should equal the mode from the line output in edidparser
