VGA to DVI-I.

[Erick Aguilar]

Hey guys, quick question.

My GPU (Sapphire HD7770) comes with both DVI-I, DVI-D. Also HDMI and a display port, and I want to use dual monitors. One is a 23'' monitor, and the other one is a 19'' one I intend to use as a reading/playback monitor while the main one will be exclusively for gaming. The thing is that the first monitor has a VGA and DVI-D output while the 19'' has only a VGA output.

I was wondering what would be a possible way to wire both monitors to make them work together?
In my mind I was thinking that the 23 inch could just run with a DVI-D cable, and perhaps the 19 inch could run with a VGA->DVI-I adapter in the video card?

Or perhaps the 23 inch could use an DVI-D to HDMI cable and the 19 inch the vga to DVI-D adapter for the GPU?

Thanks for your time!

You cannot run VGA off of the DVI-D connection it must be the DVI-I.

.. isn't DVI-D analog and compatible with VGA? because that's how one of my monitors is working right now.

DVI-D is Digital only, DVI-A is Analog only. DVI-I is a combination of both. VGA is purely analog.

So the only thing that would work is to have one monitor run a purely on DVI-D and the other one on VGA to DVI-I?

Correct. After making the correct connections (the 23" to the DVI-D port and the 19" to the DVI-I port with an adapter), about the only thing you may have to do is set the 23" as the primary monitor in the Windows display properties if it isn't.

Thank you stormy!

Quick extra question here, the 19'' is only VGA, would it cause any sort of impediment with the adapter? I've heard such things can happen, but honestly I hold no real knowledge about video signals and converting them.

The VGA adapters for DVI-I ports is a simple passive path-though adapter. What that means, it only rearranges varies pins to VGA, it doesn't covert any of the signals. It will not cause any issue.
