I have just installed a brand new Asus R9 280x graphics card.

I also have two brand new Asus VN248 24" monitors both connected via HDMI. One connects directly into the graphics card HDMI port, the other is plugged into the graphics card DVI port with DVI/HDMI adaptor.

I have Windows 8.1 64bit, latest Catalyst Control Centre and drivers. The PC and Windows is entirely stable, functioning, etc.

Two problems:

(1) Although catalyst correctly reports both panels have a max resolution of 1920x1080, this resolution is not shown and is not selectable in Desktop Management-->Desktop Properties. The max resolution shown is 1680x1050!

(2) If instead of selecting 1680x1050 I use HDTV-->1080p then I get a black border around the display, i.e. the monitor screen isn't filled completely. If I then go back to 1680x1050 the monitor screen is filled.

What is going on??

I have experimented with various settings in Catalyst (e.g. Scaling options) with no impact.

I'm amazed a brand new high end Asus graphics card paired with two brand new very standard Asus monitors can't work out of the box.

I've also found that the latest catalyst Control Center is relatively unstable with this card..

Thanks for any help!

I've tried. When I go to the scaling options page the "Underscan---Overscan" bar remains greyed out whether I check "Use the scaling values" or not...
So I cannot set it at all apart from switch the check box on or off for both monitors. Very strange.

I wish you luck then my friend, I've had this issue twice via hdmi and both times I resolved it using the scaling stuff in CCC. I think one time I had to lower the resolution so the slider wasn't greyed out, can't remember if GPU scaling was enabled or disabled though. If that doesn't work for you then I have no idea, sorry.

Alternative solution is to use DVI of course :(

No luck so far. I will try more with dropping the resolution and trying different combinations of scaling..
I cannot use DVI as these monitors only have HDMI ports!

Thanks anyway
