HDMI video switches are a necessary part of the modern Home Theater experience, especially if you have more than one computer in the same room together or a HDTV and a computer in the same room or other combination of devices in the same room that use similar interfaces like D-Sub or DVI connections.
OPPO is known in the Audio Video community for building high-quality components for inexpensive prices. They make HDMI cables, the HM-31 HDMI switch being reviewed here, and Universal DVD players with HDMI connections. The HM-31 is the first device from OPPO that I’ve received on the review bench.
