This step-by-step article shows you how to connect to Windows XP Terminal Services using a video resolution greater than 256-color.
When you connect to a Microsoft Windows XP computer by using the Windows XP Remote Desktop Connection client, you can select the color resolution at which you would like the client session to run. This functionality allows you to increase the resolution beyond the former limitation of 256 colors. However, by selecting this value, you are not guaranteed to connect at as high a resolution as you select because the client setting is only one of the facets required to generate a particular color resolution in the session.
Increase Video Resolution for Windows XP Terminal ServicesWhen you connect to a Windows XP-based computer by using the Remote Desktop Connection client, you can specify for the client to run with more than 256 colors. Before you specify a color-resolution setting, you must first set up Remote Desktop Connections. To do so, follow these steps:
Set Group Policy for Maximum Color Depth of Terminal ServicesIn many cases, after you perform these steps, the client still connects with 256 colors rather than whatever value you specified in the Remote Desktop Connection box. This behavior can occur because of a group policy on the Windows XP-based computer that determines the maximum color depth that can be negotiated by the client. In Windows XP, the default policy setting is 256 colors, but this setting can be changed by using the Group Policy Editor.
To use the Group Policy Editor to change the setting, follow these steps:
NOTE: You cannot specify and connect at a higher resolution than your video hardware can support. Therefore, if you have a video card in your computer that supports only up to 256 colors, you cannot connect to a session with a higher resolution than that.
