The default setting for my ASUS VS247H-P Monitor was 1920 x 1080 but the display didn't fit the screen. I had to change the display to 1680 x 1050 to get it to fit but then when I started gaming (on steam) the display again did not fit. I am using HDMI right now because when I try DVI nothing shows up besides the windows background, no icons or anything. For the VGA output although the cords are connected it says there is no signal. I have an AMD Radeon HD 7850 graphics card and the HDMI and DVI cords are currently connected to it. The VGA cord is connected to the motherboard.
