2 DVI, 1 HDMI Eyefinity?

I have a single Diamond Radeon HD 5770 in my machine. I was wondering if I could do a triple monitor Eyefinity via 2 DVI out, and the HDMI rather than the display port. I read you always need to use the display port, why? If their all digital outs?

  1. That's the way the cookie crumbles. You need to have 1 active displayport adapter.

    An alternative is to purchase a sapphire FLEX 6770 which eliminates the need for those adapters. Be aware though, you will not have a good experience if you were to use a single or xfire 5770/6770's to run eyefinity gaming if that's what you are doing it for.

  2. ^+1. Even a single 6950 2GB struggles with 5760x1080. Buy if you just want to get a feel of what Eyefinity is all about & you already got the triple monitors, then an active dp-dvi adaptor is just a small investment. It will be worth it because you can still use it when you go big time with Eyefinity.
  3. Okay, I had 3 old VGA Monitors. I've used two DVI-I to VGA converters for double eyefinity, the Display port to VGA should work too right? Im just testing, they are 15. 1024 x 768 monitors. My single 5770 should handle a few test runs of MW2, right?
  4. Yes it should.

    Sure. No harm in trying now since you got all necessary components for Eyefinity. Good Luck!

    The reason you need the display port adapter is the internal clock setup. Basically on the 5 series cards from ATI, one of the HDMI and DVI ports shares an internal clock (basically its just 1 connection with 2 heads on it) so they both cant be used at the same time.

    I was running a 5850 with EyeFinity for about 2 years before upgrading to my 7950. You'll have to keep settings real low to get playable frame rates on a 5770. As far as the Displayport to VGA, it will be hit or miss. Some people have managed to get EyeFinity working this way but a lot of others havent. If you do get an adapter make sure its one of the ones recommended by AMD, I've had problems in the past with other adapters.
