However, it is capable of changing the resolution and uses DDC2 to pick an appropriate video mode. .Pp A 2D graphics engine is used to accelerate all drawing operations. Direct access to video memory is not required by .Nm . .Sh SEE ALSO .Xr genfb 4 , .Xr wsdisplay 4 .Sh AUTHORS .An -nosplit The .Nm driver was written by .An Michael Lorenz .
