You will not get them both to work reason being 2 different generations and 2 different ram types one being DDR3 and other DDR5

I didn't notice you were trying a 4850 and a R7 GPU besides you should be able to use 2 monitors with just the R7 and use the other as a backup

The pic on the Asus site shows DVI-I and DVI-D. IIRC only DVI-I has analog data.

The asus r9270x has...

D-Sub Output : Yes x 1 (via DVI to D-Sub adaptor x 1)
DVI Output : Yes x 2
HDMI Output : Yes x 1
Display Port : Yes x 1 (Regular DP)
HDCP Support : Yes

You have multi monitor support. Remove that 4850. You can not xfire different gpu's, they need to be the same model.

By rights, with just the 270x installed (plus the drivers) the 4890 should be seen and usable.

You cant have two different versions of Cat drivers installed.

And as mentioned above, it is not possible to Crossfire the 4890 and 270X.

Since you only need to run to two monitors, I'd remove the 4890. For the VGA inputs on the monitors, simply purchase 2 DVI> VGA adapters. If all you have cable wise are VGA cables, you will need two DVI cables as well.

I'm pretty positive that AMD cards only support an analogue display via adapters from one of the DVI out puts, at least this has been the case for the AMD card's I've owned.

Quote:
There are a variety of DVI ports which support different connections. The ATI 6800 series cards commonly have the following DVI connections:

one DL-DVI-I
one SL-DVI-D
DL is dual link which provides support for higher resolution like 2560x1600, SL is single link which doesn't support higher resolutions like 2560x1600, DVI is the connector form factor, I is integrated digital and analog support and D is digital only support

So only the first supports an analog connection using a simple adapter.

Found out that there is no adapter to transform vga to dvi-d because dvi-d is digital and vga is analog.
