I recently bought a computer bundled with a monitor and the monitor looked fine out of the box. When I turned it on, I noticed about 1 inch black space between the edge of the monitor and the lit up screen. The monitor is the Acer P246HLAbd (UM.FP6AA.A01) , widescreen 24" and 1920 x 1080, using HDMI cable and my graphics card is r7 260x. Any solutions?
