ich habe alle diese Lösungen ausprobiert, aber ohne HDMI ist der VNC-Viewer in einer niedrigen Auflösung eingestellt. Aber ich habe endlich gefunden, wie man die erforderliche Auflösung
auf dem VNC-Client

erhält : Installiere x11vnc und

dann

x11vnc -configure 1024x600

. Nun erscheint diese Auflösung als VNC-Viewer auf meinem Chromebook.

However I prefer the RealVNC software . Installed the latest RealVNC server (version 6.4.1) on my RPI 3b+.

I have not succeeded to get the VNC client in the high resolution setting via the config.txt.

Software looks first at the HDMI port. If no HDMI monitor is connected it start in the low resolution version.

To simply solve this problem, I have added a Dummy HDMI dongle to the HDMI port then I get high resolution on the Chromebook and other systems as an VNC client. These plugins cost around € 8 to 10,-

Settings in the config.txt:

HDMI_safe=1

HDMI_force_hotplug=1

That is all you have to do.

Works perfect now and fast with the latest kernel version 4.19.36-V7+ and latest updates. VC4 driver (OpenGL) full to on.

Regards,

Bram
