This is not VESA compliant.

This will not give the correct pixel clock for a framerate of 60 frames
per second (as probably expected).
Just as a warning: Due to the non-standard video timing most hdmi
monitors will not work. For more compatible settings please have a look
into the tbs2910 board code.
