Summary: Connecting this device between my two 30 inch DVI-D Dual-link only monitors limited my resolution to 1280x800. I had to switch to 22 inch DVI-D Single-Link monitors to get the results I wanted. The assignable USB and Audio ports are nice for my NMS server. I recieved an excellent education on EDID, DDC and monitor technology. It was too much hassle for the price.
