Monitor resolution not properly detected in Linux (Debian 7 or Wheezy)

So I have an ATI HD5xxx graphic card in my desktop personal computer. It’s a nice and quite fast card. It also has three display adapters: HDMI, DVI, DisplayPort. On my desk, there are two monitors. One of them have a DVI and a VGA adapter. The other however, only have VGA adapter. Do you see the problem here?

My graphic card has no VGA adapter, because of this, I need to use some adapter, and because I used an adapter, the resolution of the monitor is not detected properly. The native resolution of that monitor is 1920x1080 pixels, but I can only set it to 1440x900 when I use the adapter (which looks quite ugly). This problem is easily solveable in Windows 8. The windows’ ATI Cataylst has an option to force a resolution on the monitor. So I can just force 1920x1080 and it works perfectly. Debian (or other distribution like Fedora) however, does not have this option..
