What video port is this?

[Parzival120]

I have a question down below is a picture of my gpu and what are those 2 ports on the back? And what resolution are they capable of? Sorry that the photo is a bit blurry and don’t make fun of my gpu we all know how bad the gpu shortage is.

Lol, DVI.

dvi...

That is DVI dual link. Is that a GTX 500 series card? Possibly a 570?

Those are DVI-I connectors. You can use small adapters to convert them to HDMI or VGA if needed.

It’s a gtx 460. I got it for free because of gpu shortage. And do you know if that port is capable of 1080p?

Yes, can do 1080p 144hz. I use DVI on my GTX 980. You'll need a dual link cable for that though - it can do 1080p 60 over a single link cable however!

Yep, it is.

Thanks one question though. Im looking on Newegg for an adapter and I found a DVI I dual link but on the left side of it, it just has a rectangle when on the dvi port in the back of my gpu it also has 4 square holes. Are they compatible?

Yep.

Yes,they are compatible, the slot and spade is a ground.  The other 4 pins would be for analog which you don't need.

That is a DVI-D port. REMEMBER that DVI does not do audio. Might not be an issue, but for some it is.

To be precise and as clear as possible, they're DVI-I Connectors. 

DVI-I means it has both digital and analogue signals in it. A digital only connector would be DVI-D, and an analogue only connector would be called DVI-A. 

 

The analogue part of the DVI connector has all the wires needed for a VGA connector, so you can use a very basic DVI-VGA adapter to get a VGA connector, or you could buy a DVI-VGA cable (though it would be rarer so more expensive).

 

HDMI is designed on purpose to support a subset of DVI, so you can use a very basic HDMI - DVI adapter to convert the digital part of the DVI connector into a HDMI connector.  Or, you can use a DVI-HDMI cable for the same result.

 

The digital part of the DVI output can be Single Link or Dual Link - Dual Link means there's more wires used to transmit the signal, and therefore you get higher resolutions or higher refresh rates.  It's like pci-e lanes ... Single Link is like a pci-e x1 slot,  Dual Link is like a slot with 2 pci-e lanes... you can transmit twice as much data.

 

Single Link means you get maximum 1920x1200 at 60 Hz, or higher resolutions but at 24 or 30 Hz. It's also the only part that's supported by HDMI, so a basic HDMI-DVI cable or HDMI-DVI adapter would only support maximum 1920x1200 60 Hz.

 

If the monitor supports Dual Link and you have a Dual Link cable, then up to 2560x1600 is supported, or lower resolutions but higher refresh rates like 120 or 144 Hz.

In theory, you would tell if the cable is Dual Link if the DVI connector has all those pins installed, and a Single Link cable would have around half of those pins... but in practice, a lot of brands leave the pins installed, they just don't connect wires between those pins, making the cable thinner and cheaper.

 

 

The VGA output is usually limited to 2048 x 1536 or something like that.

 

 

If a cable has connectors that don't have those 4 pins around that wide pin on the side of the connector, that means the cable can only carry the digital part of the signal, it's a DVI-D cable.
