Why do I get the error "Couldn't open the display device"?

Home / Support / Frequently Asked Questions / Why do I get the error "Couldn't open the display device"?

This error occurs when the fullscreen option is enabled in the display configuration and the given x/y resolution isn't supported by the display, for example a resolution of 240 by 320, which happens to be the default desktop resolution of EDGELIB.

Set the videowidth and videoheight to values supported by your monitor, or disable the fullscreen option. Configure EDGELIB in the <span class="inlinecode">OnDisplayConfig()</span>. callback of the framework
