Are you sure it is an "Eyefinity". A DisplayPort is a requirement for Eyefinity. You cannot do Eyefinity if the card does not have a DisplayPort.

3-Display setup is not the same as Eyefinity, what are you trying to achieve? Are you trying to use a computer with 3 monitors or play a game on 3 monitors as a "ultra widescreen"?

The only way for a Radeon HD card to support 3 monitors regardless if it is "Eyefnity" or a "mere 3 display" setup is to have an Eyefinity card. That means DVI / DVI / DisplayPort or DVI / HDMI / DisplayPort.

The issue is non-Eyefinity only has one RAMDAC (Random Access Memory Digital-to-Analog Converter). Each RAMDAC only supports two video outputs. DVI / HDMI / VGA all use the same RAMDAC. If the graphics card had 2 DVI ports and 1 HDMI port, those 3 ports are all connected to one RAMDAC which can only support 2 video outputs.

The hardware for the DisplayPort includes a RAMDAC specifically for the DisplayPort. Therefore an Eyefinity card will have 2 RAMDACs which means it can support 3 monitors. Technically speaking it should be capable of supporting 4 monitors since there are 2 RAMDACs.

Yes, but he didn't provide if he had a DisplayPort on his GPU. I was assuming that he would have a Intergrated Display on his motherboard, which can enable 3 displays.

That was what I was saying...

He only listed DVI, VGA and HDMI ports. That does not qualify as an "Eyefinity" card. Thus, it is not capable of supporting 3 monitors. Note, the OP stated:

I agree... We should wait for the OP to reply to confirm our thoughts...

Thank you guys , you are right I don't have display port which I don't understand why they didn't put one in for this card with 2 GB memory , I was looking around and a way cheaper one had DVI DVI displayport , oh well I guess I have to buy another if I would like to run more than 2 monitors at the same time. But thank you again for the fast and good response great forum to be a part of .
