The graphics card has been set into a mode to specifically display the overscan area since Area5150 uses this.
Showing the overscan section should not be normally done as it leads to non-standard resolutions and weird display signaling so many monitors run into problems receiving this input. My 4K monitor happens to be one of the few to at least make an attempt to display this.
There are many display errors in this demo and some problems could be inherent to the original Graphics Gremlin, configuration of my system or the force display of overscan.
HDMI: Dell S2721QS 4K monitor
