Please Advise On Two-Monitor to 7870XT GPU Cable/Connection

Hello, and thanks for reading.

A new Sapphire 7870 XT GPU is on its way to me now. It features four ports for monitors/TVs:

1. DVI
2. HDMI
3&4. 2x Mini Displayport

I have two monitors I'd like to connect to the card. An Asus VS238H-P and an old Dell P1130 CRT. The Asus uses a DVI cable and the Dell uses a VGA cable for which I currently am using a VGA-to-DVI adapter (with my current GPU, a Gigabyte GTX460OC that has two DVI ports).

So, now that I'm down to a single DVI port, what's the optimal way to configure these two monitors (DVI and VGA)? It seems that almost every option is available to me, from getting a VGA-to-HDMI adapter/converter to getting a DVI-to-Mini Displayport adapter/converter.

It should be clear that the Asus, being a modern LED model, is my main and the Dell is my secondary, so the Asus needs to be connected to the "best" connection on the GPU, if one or several are better than the others. Not sure its relevant, but the description of the 7870 XT includes the following: "Cutting-edge Quad HD display support (4K Support) — The display resolution on AMD Radeon HD7000 series is quadrupled to the resolution of 4KX2K( 4096X2160 ) from the outputs of DisplayPort 1.2 and HDMI."

Thanks so much for taking the time to read. Any input would be greatly appreciated.

DVI the asus; use adapter to get the dell going. 1st slot to main; 2nd slot to second. That is what I am doing with mine (asus 24' + dell 19" portrait mode). I use a headset as well.

Your Asus monitor has an HDMI port - just grab an HDMI cable and use that, using the same connection for the dell monitor you usually do.

Both approaches sound entirely reasonable. HDMI-to-HDMI from the Asus intrigues me...I knew it had the input (as well as perhaps several others), but (and here I'll again reinforce my ignorance), I wasn't sure what the intention was (I figured possibly for chaining several monitors to each other, TVs?). But of course that makes sense (wish they'd included an HDMI cable as well).

Anyhow, that sounds like a simple solution. Does DVI have any advantage over HDMI or mini displayport or vice versa (not considering sound, which I know HDMI handles, but my monitor doesn't have speakers, so not an issue)?

Thanks.

Monitors never include HDMI cables - they want you to pay for them.

The only difference between DVI and HDMI is that hdmi has sound - the picture quality is the same.

displayport can handle a higher resolution, but that doesn't matter, as you don't have silly high resolutions anyways. It can also run multiple monitors off one port, but it's expensive to do so.

If you live in the USA, don't go down to BestBuy to get the HDMI cable.
www.monoprice.com or Amazon.

Thanks, everyone, for the valuable input. Especially good to know that DVI and HDMI are visually equivalent. Simple solutions are often best, so I'm going to grab that HDMI cable.

Thanks again,
