VMware GSX Server Virtual Machine Guide

Setting Screen Color Depth

in a Virtual Machine

The number of screen colors available in the guest operating system depends on the

screen color setting of the host operating system.

Virtual machines support

• 16-color (VGA) mode

• 8-bit pseudocolor

• 16 bits per pixel (16 significant bits per pixel)

• 32 bits per pixel (24 significant bits per pixel)

If the host is in 15-bit color mode, the guest operating system’s color setting controls

offer 15-bit mode in place of 16-bit mode.

If the host is in 24-bit color mode, the guest operating system’s color setting controls

offer 24-bit mode in place of 32-bit mode.

If you run a guest operating system set for a greater number of colors than your host

operating system is using, you can encounter various problems. In some cases, the

colors in the guest are not correct. In others, the guest operating system is not able to

use a graphical interface.

To fix these problems, you can either increase the number of colors available on the

host or decrease the number of colors used in the guest.

For best performance, use the same number of colors in the guest and on the host.

The following sections describe changing the color depth on the host and in a virtual

machine:

• Changing Screen Color Depth on the Host on page 334

• Changing Screen Color Depth in the Virtual Machine on page 335

Changing Screen Color Depth on the Host

If you choose to change the color settings on your host operating system, you should

first shut down all guest operating systems, power off the virtual machines and close

the console.

Follow standard procedures for changing the color settings on your host operating

system, then restart the console and the virtual machines.
