commit 55d3aa8f6d01ca5fec671459da0c17c9ddb0bea2
Author: Kevin Brace <kevinbr...@gmx.com>
Date: Sun Oct 22 20:24:04 2017 -0500
Version bumped to 3.0.50
This version adds initial support for DVI provided by CX700 / VX700
and VX800 chipsetsâ integrated TMDS transmitter. Standby resume was
tested with the DVI, and it is working.
