I use nomachine to go from laptop to different machines and these days only occasionally have blank or white screens. ctrl+alt+0 detach / connect always clears it up.
There are reports and fixes from older versions on nomachine's support forum.

When connecting to odroid remotes I run x11vnc server since it seemed more lightweght and use TigerVNC over ssh tunnel as a client without problems.

When first bringing up an odroid I use a monitor plug to get the initial remote GUI working and to be able to set a high screen resolution, then remove the plug.
