1.Represents the size of the display that is accessible by Services—not the full resolution of the physical display.

2.The Cisco Unified IP Phones 7905 and 7912 have pixel-based displays, but they do not support XML images.

If the number of colors in the image is not reduced to match the phone capabilities, the image will be dithered by the phone and yield less than desirable results in most cases. To reduce the number of colors in a graphics editing program, such as Adobe Photoshop, use the “Posterize” command. The “Posterize” command takes one value as input for the number of color tones per color channel. For example, using the value of 16 (4-bits per channel = 16 tones per channel) will correctly dither the color palette of the image for the best display results on the Cisco Unified IP Phone 7970G.
