You may also want to use a frame buffer before your clocked video output
if for any reason the SGDMA block cannot output the data fast enough to
keep the clocked video output's internal FIFOs from starving.

Not only Clocked Video Output has FIFO.
SGDMA also seems to have built-in FIFO.
FPGA's internal memory also can be used as an additional FIFO to prevent Clocked Video Output's FIFO from underflowing.
What really can happen in Windows environement when all these FIFOs could be not enough and only presence of a Framebuffer could prevent loss of videodata?
