I was able to remove the black border by appending the following lines to config.txt:
hdmi_group=2 hdmi_mode=82 hdmi_cvt=1920 1080 60 3 0 0 1 framebuffer_width=1920 framebuffer_height=1080 max_framebuffer_width=1920 max_framebuffer_height=1080 The lesson I learned was that the Pi needs to be physically powered off after making changes to the config file. ctrl-t ctrl-t r is not sufficient. / > On 5.
