Hello,

Basically, I just decided to move my brother's old monitors over to add to mine. The unfortunate thing is, they are SyncMaster S23B350's, and they do NOT have DVI. They only have HDMI and VGA.

This leads me to my current situation:

I have

1) SyncMaster B2330 (VGA, HDMI, AND DVI)
2) 2 X SyncMaster S23B350 (VGA AND HDMI)

Through Sapphire's website, I found this.

"To support 3rd monitor without DisplayPort cable connected, 2 of the 3 monitors should be the same model with DVI ports connected. The driver version should be v13.12 or above."

My GPU only has 2x DVI, HDMI and Displayport.

Okay, so I have two monitors that are identical. The problem is they ONLY have VGA/HDMI.

How do I get the 3 monitors to work?

-------------------------------------------------------------
Is it possible I hook up my Samsung B2330 with a HDMI cable, then buy 2 DVI-HDMI adapters and use those to hook up from the GPU's DVI ports to the S23B350's HDMI ports?
-------------------------------------------------------------
Because right now, I have hooked up my B2330 with DVI, and then a S23B350 with HDMI.
The 3rd one I tried connecting with a VGA cable using a VGA-DVI adapter. It is not working.
-------------------------------------------------------------

Sorry for the wall of text.

Please help. Thanks

"The catch here is that these can’t be independent displays, and this change is primarily intended towards enabling Eyefinity with cheap, DVI/HDMI-only monitors. To utilize clock sharing and to drive 3 such monitors off of a single card, all 3 monitors must be timing-identical, which functionally speaking almost always requires the monitors to be completely identical. Furthermore the sharing of the clock generator can only be engaged/disabled upon boot, so the 3rd display cannot be hot-plugged and must be present at boot time. Consequently this is by no means as unrestricted and easy as having native support for 3 TMDS interface displays, but for Eyefinity it will get the job done."

*If I read this correctly, this is for Eyefinity with a single "virtual" monitor not three separate displays such as a main screen and two exteneded screens. If you want to run different programs on each monitor for example, I don't think this will work.

As for the 3rd monitor issue it seems to be spelled out fairly clearly by what you posted as in "must have TWO of the same model with DVI". You don't have the proper monitor inputs recommended which is why you can't get it working.

I read that article.

But do you think it would be possible to get 2 DVI-HDMI adapters and then hook those two monitors to the DVI ports on the GPU with HDMI cables?

Then the B2330, I'll connect with HDMI.

Would that work?

What other alternatives would I have if that won't work? Must I buy an active Displayport-HDMI adapter?
