Essentially this is my question: Use Remote Desktop with custom DPI
But here is caveat: I'm remoting from Mac to Windows 10
I didn't find any mentioning how to do it with Win 10 and solution proposed in above link is for old RD client for Windows.
I can use either Royal TSX or Microsoft Remote desktop. Both result in RD session with 100% DPI. On a remote machine I can't change DPI. But it's set to 150% when I work normally..
This basically make my goal of working remotely not achievable :( I can't see a screen..
