Hi All,

Just purchased a new MOBO / memory & APU as below to replace my ageing rig.

I need dual monitors running as I use the rig as a Karaoke / DJ. In my old giga board I output via the VGA port to Karaoke screens the DVI to my screen.

Problem is no matter how I config this board, I can not get it to see two monitors plugged into the VGA & DVI ports. I know if I enable dual DVI output in the BIOS it disables ALL the other ports, but when I do this I get a max resolution of 860 which can not be changed. If I disable the Radeon driver and use the stock Windows 7 driver I can get full range of resolution !.

I disable the BIOS dual DVI option and the board will not see the DVI monitor but will see it if I plug it into the VGA port.

First system I have built with the FM1 footprint.

The other thing is the rear on board USB ports will not recognise anything plugged in on POST, until Windows boots up.

Is this a fault on the board or have I over looked something?

Board RMA'd for same but still same problem with replacement.

GR8 help from vendor tech. support who arranged different board and a discount on postage TA.

Lets hope this works and it hasn't been an APU problem.
