I purchased this product to share my DVI monitor and Logitech Bluetooth keyboard/mouse between my two main machines - the exact use promoted by the manufacturer. I successfully patched the firmware to eliminate the incessant beeping, but am extremely disappointed with the DVI video at 1600 by 1200 (severe streaking and noise), and the audio is totally unuseable given the severe hum and noise. BTW, I am using Belkin KVM cables.Don't even THINK about purchasing this unit!
