I am a beginner with using realvnc. I have a headless PC which runs remote application and steam. The vncviewer is always black screen when I use realvnc instead of mstsc. Now, if I plugged monitor to the display card, the vncviewer could display content while it was connected.
1.I noticed that, if I un-checked the directX relatived opinion and un-plugged monitor, the vncviewer could show some content such as Microsoft 365 copilot and notepad, but some of the window are displayed as black screen such as CPU fans which may be using directX technology.
2. How to use vncviewer in vmware workstation?
I use virtual machine with bridgged host network or NAT, enable the vnc in the opinion and give a port which is not used. Connect to the HOST name or ip address rather than the virtual machine’s network name or ip address, I can connect the virtual machine with vncviewer.
