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.
Thanks for the pointer. I'll take a look at the tbs2910 code when I expand the set of supported display presets. For now this is a preliminary support.
