Hello Reju,
DVI-I is available. The one I got is DVI-I to HDMI adapter. My relative is using Sharp PGF-320W projector and it has DVI-I connection. There is something called HDCP compliance. I am not sure if there is DVI-I connector with HDCP compliance and if we want to connect it using adapter then in order to comply with HDCP should we use DVI-I or DVI-D will also do the job.In my opinion theoritically DVI-D should do the job since we are transmitting digital signal. But not too sure about it.
Thanks,
Mahiruha.
