Since modern displays do not have an overscanning issue, there is no need for the video card to counteract this assumed problem by underscanning the video output sent to it. The Fix: Change the Scaling Level to 0% Overscan Therefore, it sets an underscan value of up to 15% to counteract the assumed problem. It assumes there is a risk for the image to be cut off by the display. When the image is underscanned, as it is the case here, it means that the video card doesn't correctly identify the display connected to it and its capabilities. Underscan is the exact opposite: the video card must constrain the size of what it sends over to the display, to counteract the overscan.That's why video card drivers allow you to set the overscan only to 0 and not to higher values. Therefore, there is no danger of having the image shaved off. Modern displays have integrated overscan and they now display what they receive as an input, pixel by pixel. This meant that there were "non safe" areas on the screen where the image could be shaved off. Old means displays produced in the 1930s through 1970s. Only very old TVs and displays required overscanning because they used different technologies for displaying the image. This is not a problem of the modern world though. Overscan is when the image is shaved off by the display but not by the video card.Its extremities are named underscan and overscan: On some High Definition displays, especially when using the 1920 x 1080 resolution, the scaling is incorrectly set by the driver.ĪMD drivers apply a default scaling value and they have a slider you can use to change it.
The Culprit:The Scaling Setting for the AMD/ATI Video OutputĪMD/ATI video cards have a scaling setting in their drivers, which tells the video card if it should resize the video output delivered to the display, or not. Then, the problem can be encountered both in Windows 7 and Windows 8 as well as when using multiple versions of Catalyst Control Center (CCC). You can encounter it when using both HDMI or DVI cables to connect the video card to the display. Also, this problem is not specific only to a certain type of video output. It happens on all kinds of AMD/ATI video cards, from the older AMD HD 4000 series to the newer AMD HD 60 series. It happens on all kinds of monitors, from diverse manufacturers like Samsung, Asus or Acer. However, I dared to do a bit of searching and, to my surprise,I learned that this problem is not as rare as I thought. I thought there was something wrong with my monitor and I feared I had to return it. No Full Screen Image, Blurry Image, AMD/ATI video card
