I've bought a new monitor and hooked it up to my old PC, but the max resolution I can get it to display using the operation system setting is 1920x1080 60hz, but it does not fill the entire screen. The specs for the graphics card says it should display a larger resolution. Can anyone help?
Details
Monitor - Dell U2417H
Mobo - A55BM-K
Graphics - AMD Radeon HD 7480D
Max Res - 2560x1600 @ 60Hz
D-sub - 1920x1600 @ 60hz
RAM - 8GB
Now the monitor has HDMI, DP and mDP ports and the graphics vga and DVI-D(Dual Link). I've connected them using a DVI-D(Single Link) to HDMI cable.
