• Gamma level: Controls the luminance of the pixels, with values ​​from 1000 to 2200, with 1900 being the standard.
• Pixel structure: Defines whether the display is flat, RGB or BGR, modifying the way text is rendered.
• Text contrast level: Adjusts the thickness and contrast of the letter lines, in values ​​from 0 to 6.

The keys in the registry are usually found in:

• HKEY_CURRENT_USER\SOFTWARE\Microsoft\Avalon.Graphics\ for user values.
