Question: Will it work if I am using a double link dvi cable instead of a single for this application?
Answer: Yes, a dual link cable will work as it is reverse compatible. Please note that the switch is not capable of dual link though, so you will only get single link functionality.

Question: Hi, my question is about the input signal. The switch comes with 8 DVI-I connectors. May I connect a VGA input signal using VGA/DVI-I adaptor with this switch, or we must only use DVI signal? If this switch accept only DVI-D signal, why are 8 female DVI-I single link connectors are provided?
Answer: Thank you for your inquiry,

The NTI SM-8x8-DVI video switch only supports digital DVI signals -passive VGA/DVI adapters would not be compatible- but you can use Adder DVI VGA to DVI converters to plug in VGA video sources. You can also plug VGA displays as outputs using NTI DVI-VGA DVI to VGA converters.

The SM-8x8-DVI switch features DVI-I connectors for greater flexibility so you can use single-link DVI-I or DVI-D cables (DVI-I connectors are backwards compatible with DVI-D).
