Windows 10 Version 1809, Remote Desktop Connection not working from PC but working fine from macOS. – Microsoft Tech Community

Hello,

I stumbled across a similar problem.

Between 2 Win10 Pro 1809 I only got a black picture, but I could control the computer in the session: It was possible to write texts, click icons and move windows.

After some debugging I noticed that I had different MTU settings for host and client.

I then tested the following settings:

• Host: jumbo frames 9k + client: jumbo frames off = black screen as described above
• Host: jumbo frames off + client: jumbo frames off = runs immediately
• Host: jumbo frames 9k + client: jumbo frames 9k = runs immediately
• Host: jumbo frames off + client: jumbo frames 9k = frozen waiting-cursor with login image, which is also frozen. After approx. 40 sec. desktop appears and it seems to work normally

I hope I can help someone with their problem.

sincerely yours,

Heiko
