This is an LCD panel, they work somewhat differently and the
refresh rates are not that relevant.
I've run panels with very low refresh rates! You get some surprising
results! I've also dynamically changed the pixel clock (by a factor
of about 5) in order to stop the display DMA underrunning when doing
slow IO cycles on the same bus.
