Example Problem: 1920 x 1080 @ 60Hz Monitor Image format provided by RasPi, as above. Reported by monitor and by RasPi.

tvservice -s

Reduced image size.

lxde -> Preferences -> Monitor reports 1824 x 984

Solution (Information obtained from above references): Generated a /boot/config.txt file added line

disable_overscan=1

This put the image at full 1920 x 1080. This put the image right to the edges, but was a too close. Edited the config.txt to read.

disable_overscan=1
overscan_left=5
overscan_right=5
overscan_top=5
overscan_bottom=5

This gave the image a 5 pixel border.

Occasionally the RasPi reboots with a centralised colour reference square, but generally boots normally.

References above also give information as to disable the RasPi HDMI Hot-Plug Detection which will eneble the HDMI output even if no Monitor is detected.
