With Windows 7 comes Remote Desktop v6.1.7600.
I have seen a lot of posts where people want to reduce the color depth to 256 colors, which is not allowed via the Display Tab – Colors. Doing some research i found that if you have a “saved” rdp connection, you can open it in notepad and modify a specific field to allow you to run in 256 colors or 8-bit. See below for the example text, the rest is easy 🙂
Here is an unmodified RDP File, i only included the first 4 lines, as that is all that is relevant.
screen mode id:i:1
Notice the session bpp:i:15, change the 15 to an 8(as below) and save the file. Re-run the RDP connection and you will now be in 256 colors or 8-bit.
screen mode id:i:2
