Screen resolutions have various color depths, which identify the number of distinct colors the computer can reproduce in an image. The higher the color depth, the much better pictures and videos look on a screen; color depth of 1-bit, for example, has just two colors offered– black and white– while 32-bit color can display more than 4 billion colors. While some service experts do not need high color depth to complete their work, users who deal with photography, art, graphics or video require a display that includes the highest number of colors available, which in Windows 7 is 48-bit color.
1. Minimize all windows on the screen and right-click the desktop. Select “Personalize” from the context menu.
2. Click “Advanced Settings.” Select the “Monitor” tab and select “32-bit” or, if offered, “48-bit” from the drop-down menu.
3. Click “OKAY” to close all windows and increase the color depth of the screen.
The screen resolution can control which color depths are available for selection. Smaller sized screen resolutions, for example, may not support color depths in excess of 16 bits or 24 bits.
To have access to 48-bit color depth, your video card need to support it, and your monitor should be linked to the computer system through high-definition multimedia user interface 1.3 or better.
