Dual monitors in Fedora 23

[APM]

Hi,

I have an old PC running Fedora 23 ,display to an old 17" tft monitor.
All good and fine until I introduce a 40" HD TV as a second monitor when the only resolution the linux display function will let me choose is 1920x1080 5:4 where I need 16:9 for the larger screen.

I'm only a casual linux user so I am not aware if there are any applets or ways and means to get the OS to display to both monitors in 16:9 and would very much appreciate if someone could point me in the right direction please.

The graphics card is a Radeon 4900 basic model I think and has HDMI out to the TV and VGA to the monitor.

Thanks.

I should add I can't see how to access the GPU at all from Fedora.

No help for this one?

I'm beginning to think I need a native 1920x1080 16:9 monitor to pair with the HD TV screen.

The monitor doesn't support 16:9,it is 2005/2006 vintage so fair enough.

A good excuse for a new screen.
