 GPU-68: How to Configure GPU Scaling Option in AMD Catalyst™ Control Center

Article Number: GPU-68

​​This article provides instructions on how to configure the scaling options in the AMD Catalyst™ Control Center.

Reasons to Configure GPU Scaling:
GPU Scaling performs all image scaling using the scaling features of the graphics card.

  • Practical to users that want to maintain aspect ratio for older games and applications that still run in a 5:4 aspect ratio format on widescreen display devices
  • Practical to users that deliberately want to stretch a 5:4 aspect ratio resolution on a widescreen monitor
  • Practical to users that want to reproduce a non-native resolution pixel per pixel on a display device

Requirements to Configure GPU Scaling Option:

  • A digital connection such as a DVI, HDMI or DisplayPort™ must be used
  • The desktop must be set to a lower non-native resolution. Refer to the display device manual to determine the native resolution. This will be important to know when configuring the display to a non-native resolution

Instructions for Configuring the Display Device to a Non-Native Resolution:
To access the GPU Scaling feature within AMD Catalyst Control Center:

  1. Right-click anywhere on the desktop and select the AMD Catalyst Control Center
  2. Click on the Desktop Management menu and select Desktop Properties
  3. Change the display to a non-native resolution
    For Windows® XP users, expand Displays Manager and change the display to a non-native resolution under Desktop Area
  4. Example below: Changing the resolution to 1280x1024 (Super XGA 5:4) for a 24” monitor with an optimal native resolution of 1920x1080 (Widescreen 16:9 aspect ratio)


Instructions for configuring GPU Scaling:

  1. In AMD Catalyst Control Center click on the My Digital Flat Panels menu and select Properties (digital flat panel)
    For Windows XP users, expand Digital Panel Properties and highlight the Attributes tab
  2. Check the Enable GPU Scaling box
  3. Choose the GPU Scaling method desired and click on Apply. There are three different GPU scaling modes that can be selected. Choose the mode that best fits your needs (see below):
    1. Maintain Aspect Ratio
    2. Scale Image to Full Panel Size
    3. Use Centered Timings



Explanation of the Different Modes Available for GPU Scaling:

  1. Maintain Aspect Ratio
    Expands the current image to the full size of the monitor while maintaining the aspect ratio of the image size. For example, at a resolution of 1280x1024 (5:4 aspect ratio), the screen will have black bars on the left and right side. 
  2. Scale Image to Full Panel Size
    Expands the current image to the full size of the monitor for non-native resolutions.  For example, at a resolution of 1280x1024 (5:4 aspect ratio), the screen will stretch to fill the monitor. This is the opposite effect of Maintain Aspect Ratio.  Note: This feature is not designed to fix the black borders around the display with High Definition Televisions (HDTV) using an HDMI connection. Please refer to GPU-72.
  3. Use Centered Timings
    ​Turns off image scaling and centers the current image for non-native resolutions. Black bars may appear around the image. For example, setting a 24” monitor (native resolution of 1920x1200) at a resolution of 1680x1050 (16:10 aspect ratio) or lower will place a black border around the monitor.
