Can a DVI-D cable plugged to the DVI-I port of the GPU still get me 144hz?

Hello,

So this is a noob question, but better to be safe than sorry right? I already know that DVI-D is compatible with DVI-I, but can a DVI-D cable still give me 144 hz despite it being on a DVI-I port on the GPU (GPU lacks a DVI-D port)? This is on 1080p by the way.

Thanks.

Yes I think so, as long as the cable and port are both "dual link".

Yes you can... in fact, most hardware and peripheral makers use the DVI-I input port to save money on mass volume sourcing costs. But you have to check to see if the hardware behind that input port is in fact either Dual Link or Single Link support.

For example some graphic cards have two DVI-I ports, but one may be Dual Link and the other may be Single Link.

DVI-I is just a DVI-D port with VGA adapter support added on. If you plug in a DVI cable then the VGA part is not used, and it's no different than any other DVI-D port.
