This one in the bottom actually made me have to reflash sdcard, just broke the board:

Code:

$ xrandr --output HDMI1 --transform 0.80,0,-35,0,1.04,-19,0,0,1

maybe it can be manually configured somewhere else, just not so obvious for the layman.

Hello,
  I had a overscan problem with the rock64/rockpro64 that sounds like yours. Also I had a distorted picture with 1920x1080 because the edid of my canoxTV did not match the pixelclock of the rock64. I ended with a custom edid-file that brought me a clean screen but no audio over hdmi, cause my monitor is gone into HDMI-DVI mode. But you can try one of my working modeline on xorg.conf.d if you like:

Code:

Section "Monitor"
 Identifier "HDMI-1"
 Option "PreferredMode" "1920x1080g"
 Modeline "1920x1080g" 136.75  1920 1968 2000 2080  1080 1083 1088 1111 +hsync -vsync
 Modeline "1366x768"   72.00  1366 1380 1436 1500  768 769 772 800 +hsync +vsync
 Modeline "1680x1050"  146.25  1680 1784 1960 2240  1050 1053 1059 1089 -hsync +vsync
EndSection

The HDMI-DVI-mode problem with audio in  a custom edid I fixed in

Everything is better than 1024x768.
