Hello! I am attempting to get a triple monitor setup working with a Radeon HD 7870.
The card has 4 ports; A DVI, HDMI, and 2 Mini DisplayPorts.

2 of my 3 monitors are Asus VX238H's, which have a VGA and 2 HDMI ports.

The third monitor is a Samsung PX2370, which has an HDMI and DVI port.

As it is now, I was trying to use 2 HDMI -> Mini DisplayPort cables for the Asus monitors, and an HDMI - > HDMI for the Samsung, which doesn't work, as it cannot enable the third monitor. The 3rd is detected, but all 3 cannot be enabled at the same time

(As a side note, I have tried several other configurations. I have an HDMI -> DVI cable, and I've been trying to rearrange things to get it to work, but it doesn't. From what I understand I may need other types of cables/adapters.)

My question is, is it possible to get all 3 monitors to work without buying any adapters, and if not, what adapters would I have to buy? Thank you!


Also, if anyone wants an pictures or further clarification, I'd be happy to oblige.
 
Solution
Yes it will work but one of the monitors must be on a DisplayPort>DisplayPort cable or a Active DisplayPort Adapter. If you cable is not a DisplayPort or Active DisplayPort Adapter the third monitor will NOT work.

Thanks so much for the quick reply!
So just some clarification;
Would something like this work? So this would be the next configuration:

Monitor -> PC
Asus (Right): HDMI -> mDP
Samsung (Center): HDMI -> DVI
Asus (Left): HDMI -> Adapter -> mDP

Using something like this HDMI -> mDP Adapter??
