I was trying to get my DVI KVM switch to work with my laptop that has a HDMI port. I had problems with VGA to DVI adapters previously so I purchased 3 different (suppossedly) different adapters to find one that worked. I paid different prices for each and when they arrived they were all the same and NONE of them worked with my Laptop.Best of luck..
