How to configure Windows RDC to use 16-color mode?
I have found the answer myself, so sharing it for further reference of whoever may need it.
The solution is to open the
.rdp file (
%USERPROFILE%\Documents\Default.rdp by default) and edit (or add if missing) the following line:
The number (8 in this case) sets the color resolution in bits per pixel. 8 (for 256 colors) is the lowest value available through manual editing (while the lowest value available through the RDC GUI is 15).
.rdp file commands can be found here.
PS: I am also glad to mention that my practical problem (unintentional but unavoidable video streaming jamming the whole RDP channel) is solved completely! The thing works lightning-fast now. So the idea to lower the color depth was right what I needed.
