/* DISPTMG (Display Timing) */

However, this signal is provided to the expansion port. And it is used by the [[PlayCity]] and [[Play2CPC]] expansions.

== DISPTMG (aka Display ~~Timing~~Enable) ==

DISPTMG (Display Timing) signal defines the border. When DISPTMG is "1" the border colour is output by the Gate Array to the display.

The border has higher priority than pixels but lower priority than the black colour output when HSYNC/VSYNC are active.
