Dear 9fans, 

I am booting my Raspberry Pi 4B off the 9legacy SD card image 
(http://www.9legacy.org/download.html) and it boots fine with the default 
config.txt, but there is a 48-pixel wide black border on the screen. 

term% echo `{ dd -if /dev/screen -bs 64 -count 1}
0+1 records in
0+1 records out
r5g6b5 0 0 1824 984

The Pi is connected to a standard 1080p 60Hz monitor via HDMI. How can I get 
rid of the black border i.e. expand the screen size to 1920x1080? If anyone has 
accomplished this, could you share your config.txt? Also, how can I enable 
24bit colors? Thank you.
