Resolution only 640x480 when on RDP

Hello all,
I have been struggling with video resolution on some clients I am supporting.
We use Raspberry Pi 3 with WTWare (latest version always) to connecting to Windows Servers (2008, 2012) and the number of video resolution problems has been increasing in the last months. Some clients connect to the server using RDP with no problem but their video resolution stays on 640x480, some of them uses HDMI x VGA converter cabe but even changing these cables and using HDMI directly it is still a no go.
Also, we have already tried to change configurations on "config.txt" by forcing a specific resolution with no success.
Can anyone help me and throw some light into this?

There is no magic button "make it work" and no other method to set resolution on Raspberry if your adapter broke auto detection. You should read manual as many times as needed to understand, and then put few lines to config.txt:

Got it,
I have fixed the problem on some clients by changing the monitor itself using a newer one. I will look into the documentation to verify the possibilities with the ones which cannot be changed.
Thanks for the support.
