Setting Screen Color Depth

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 the following screen colors.

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 operating system is in 15-bit color mode, the guest operating system color setting controls offer

15-bit mode in place of 16-bit mode. If the host operating system is in 24-bit color mode, the guest operating

system 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 the host operating system, the

colors in the guest operating system might not be correct or the guest operating system might not be able to

use a graphical interface. If these problems occur, you can either increase the number of colors in the host

operating system or decrease the number of colors in the guest operating system.

To change color settings on the host operating system, power off all virtual machines and close Player and

then follow standard procedures for changing color settings.

How you change color settings in a guest operating system depends on the type of guest operating system.

In a Windows guest, the Display Properties control panel offers only those settings that are supported. In a

Linux or FreeBSD guest, you must change the color depth before you start the X server, or you must restart

the X server after making the changes.

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

Using Accelerated 3D Graphics

You must perform certain preparation tasks on the host system and on virtual machines to use accelerated

3D graphics.

Support for applications that use DirectX 9 accelerated graphics applies only to Windows XP, Windows

Vista, and Windows 7 guests on hosts running Windows XP, Windows Vista, Windows 7, or Linux.

OpenGL applications run in software emulation mode.

Prepare the Host System to Use DirectX 9 Accelerated Graphics

You must perform certain preparation tasks on the host system to use DirectX 9 accelerated graphics in a

virtual machine.

Prerequisites

Verify that the host operating system is Windows XP, Windows Vista, Windows 7, or Linux.

On a Windows host, verify that the host has a video card that supports DirectX 9 and the latest DirectX

Runtime.

On a Linux host, verify that the host has a video card that can run accelerated OpenGL 2.0.

Procedure

1 Upgrade the video drivers on the host system to the latest versions.

ATI Graphics drivers are available from the AMD Web site. NVIDIA drivers are available from the

NVIDIA Web site.
