Want high-def video output from your PC but don't have a built-in HDMI out? No problem. Altona's new AT-HDPIX can turn your computer's USB into an HDMI port.

The little box is Mac and Windows compatible, outputting video at a maximum of 1600 x 1200 or 720p. It devotes the entire bandwidth of the USB port for video, pulling audio from your 3.5mm stereo jack. Audio is embedded with video and then both are transferred to your HTV over an HDMI cable.

The box is available now for $179.
