Supporting Technology with Technology.: Enable 24 bit color in RDP for XP or 2003 Server




Supporting Technology with Technology.: Enable 24 bit color in RDP for XP or 2003 Server

The default maximum color depth for rdp connections to windows 2003 server terminal servers or to windows XP desktops is 16 bits. Although in the drop down in the options sections of the rdp connection program there is true color 24 bit shown as one of the selection options, the connection is never made at 16 bits. That's because the remote XP desktop or windows 2003 server has a default limit of 16 bits. To connect with true color 24 bit rdp a change o nthe remote computer has to be made using group policy editor. This can be done for a whole domain by linking the the policy to a domain OU or per computer by using the local group policy editor. The images show how to change the the pre-defined default color limit on XP or windows 2003 server limits the color depth of RDP connections made to the the systems to a 16 bit maximum. How to configure the "server side" of remote desktop to accept connections at 24-bit true color. Windows 7, Vista, and server 2008 already allow higher that 24 bit color by default.
