Windows 7: 256 Colors in Remote Desktop Connection

Why?

Reducing the color depth used for a remote session is one way to speed up the Remote Desktop (RDP) session on a slow network connection. 15-bit is the lowest color depth allowed in the Remote Desktop Connection client (mstsc.exe) of Windows 7. But, the Remote Desktop client of Windows XP had allowed a lower color depth of 8-bit (256 colors). The remote session surely looks crappy with 256 colors, but it can be a lifesaver on a slow connection! :-)

How?

There is no direct way to choose 256 colors in the Remote Desktop of Windows 7. But, a remote session can be invoked with 256 colors:

  1. Set all the remote desktop settings for the connection and save it to a RDP (.rdp) file by choosing Save As in the General tab.
  2. Open this .rdp file in a text editor. Find the line that reads session bpp:i:16. The value here will read 15, 16, 24 or 32, depending on the color depth you had chosen while saving the file. Change this line to session bpp:i:8
  3. Use this .rdp file to open a RDP session to the remote computer. This can be done by either opening this file in the Remote Desktop Connection client or by double-clicking this file. The remote session will now use a 8-bit color depth.

 

Tried with: Remote Desktop Connection client (mstsc.exe) 6.1.7600.16385 on Windows 7

    A better option for improving RDP performance is with Ericom Blaze, a software-based RDP acceleration and compression product that provides improved performance over WAN and congested LANs. Besides delivering higher frame rates and reducing screen freezes and choppiness, Ericom Blaze accelerates RDP performance by up to 25 times, while significantly reducing network bandwidth consumption over low-bandwidth/high latency connections.

    Ericom Blaze works with any standard RDP host, including VDI, Terminal Servers and remote physical machines.

    and if 15bit is still too much, but 8bit looks way too bad, is there a way to choose the middle options? 10bit, 12bit, 14bit, user can optimize according to his bandiwidth

    A solution would be really helpful
    thanks

      Mdy: It does not seem like intermediate color depth values between 8 and 15 are supported.
