I have bought a cable: one end is DVI and the other is HDMI. This DVI cable has 3x3 plus 3x3 pins with a space between these 2 groups. But the PC end has 8x3 pins. Can I insert the cable into the PC safely ? I haven't unpacked the cable: I will wait until someone answers my Q. This is the cable. I need to connect a TV to my PC to detect why there are imperfections on my LCD display.

  • Those cables typically are uni-directional. Be sure you connect it per the specification and instructions of the cable manufacture.

  • @Ramhound I was under the impression that DVI and HDMI were electrically identical, just with different connectors. Shouldn't that mean that they are bi-directional?

  • @SamForbis - HDMI supports video and audio, DVI supports video, they most definitely are not electrically identically. There is a reason I indicate to follow the instructions of the manufacture (as I was unable to verify if the author's cable is indeed bi-directional).

  • I have tried it and it works. Sound goes from my OLD repros. Now I will wait till the imperfections appear on my PC LCD to see it on TV (or not). Aug 3, 2020 at 19:09

From the picture provided, we can tell that the cable you purchased is a DVI-D (Single-Link):

By '8*3', you most probably mean DVI (Dual-Link)

If your PC's DVI input looks like this:

or this:

You should be good to go.

It sounds like your PC has a dual-link DVI port (the "8x3" you mentioned). As long as that is the case, it is compatible with any other DVI cable, as long as you don't try to insert a DVI-I cable into a DVI-D port. As far as I know, DVI-I went the way of the dinosaur along with analog displays, so you likely have a DVI-D dual-link port on your PC and the cable you linked is DVI-D single-link. You're good to go. Here's a reference image for you.
