I am thinking of replacing my Dell U2711 with an LG 34UM95 (or Dell U3415W when released).

I am running 3 GTX480's in SLI. Each card has 2 DVI and 1 mini HDMI which I am using to connect to my TV.

The LG monitor has 2 HDMI and 1 DP connector.

Can I connect the monitor via:

1. HDMI to DVI,
2. DP to DVI.
3. All of the above.

Which method is better?

Thanks in advance.

Apologies if I don't respond right away. It's 2:30 in the morning.

It all depends on the monitor. If it is 1080p, Mini-HDMI to HDMI is the best simply because DVI doesn't support progressive resolutions. However, if the monitor is 1080i, DVI will do just fine!

On the Geforce site, it says that GTX 480s can only support digital resolutions up to 2560x1600.

Barring that, if your 480s actually can support the 3440 x 1440 resolution of the LG, it would be best to go Dual-Link DVI to DisplayPort, because HDMI has less bandwidth than DVI-D and DisplayPort.

That's just false.

I failed to take that into consideration. I thought I could get away with not disassembling my water cooling loop. You have just saved me a lot of money and disappointment. :)

Thanks for the information. I'll keep this in mind if I decide to pull the trigger.

Thanks again.

Yup, no problem! Keep in mind that if you do get a Dual-Link DVI to DisplayPort adapter, you should check to see what the max bandwidth for the adapter is before you buy.

Thanks. Will keep this in mind.

I get the feeling that I have an excuse to upgrade.:)

Haha! I do, too. A single DisplayPort cable would be the best in this situation.
