H A Dudlfb.rst2 udlfb - DisplayLink USB 2.0 driver
7 DisplayLink chips provide simple hline/blit operations with some compression,
8 pairing that with a hardware framebuffer (16MB) on the other end of the
9 USB wire. That hardware framebuffer is able to drive the VGA, DVI, or HDMI
13 result with a local shadow of the remote hardware framebuffer to identify
15 pixels line-by-line via USB bulk transfers.
18 does not require any acks - the effect is very low latency that
20 non-gaming and non-video applications.
23 setting is very flexible - able to set nearly arbitrary modes from any timing.
