VNC-Server configuration [RPi 4B]

[dvv06]

Hello, friends!

Since 2019, I have been using the XBIAN 18.1 Leia on RPI 3B+ (VNC connection is successful!!!), now I have renewed to RPI 4B on the fresh Firmware Xbian 20.1.
But in any configuration, I was able to connect via VNC to Raspberry Pi, but having a black screen with a cursor.

Raspberry Pi is connected by HDMI cable to the Phillips 46 TV "1080p (TV Phillips


I have changed in the Nano/etc/default/vnc-autores file
VNCGROUP = CEA
Vncmode = 16

According to information about Phillips_edid, an OPT/VC/Bin/TVService -s
/opt/vc/bin/tvservice -s
state 0x12000a [HDMI CEA (16) RGB lim 16:9], 1920x1080 @ 60.00Hz, progressive)

The Windows 10 1709 Monitor = Dell UltraSharp 2516D 25" (2560x1440) is installed on the PC and I try to connect to the raspberry (the VNC-SERVER service is included in the atopype and operates on the RPI 4B) using the TightVNC 2.8.84 Viewer or Ultravnc 1.4.3.6 result. The result is a failure.

иIn both cases, black screen vnc-client conection
1.


Tell me who tuned it, because it is not always convenient to connect by SSH ...
I read it on the forum, but I did not find any specific instructions, everywhere there are some scraps of infromation.

Sometimes the Pi doesn’t properly detect the display. You can force it to use a specific HDMI mode by editing the config.txt file slope:

Terminal

sudo nano /boot/config.txt

Add or modify the following lines:

Terminal

hdmi_force_hotplug=1
hdmi_group=1
hdmi_mode=16

Save the file and reboot your Raspberry Pi:

Terminal

sudo reboot

You can try to force HDMI output even if there's no active HDMI connection when you connect via VNC. This can be done by editing the `/boot/config.txt` as follows:

Code:

hdmi_force_hotplug=1
hdmi_drive=2

After making these changes, reboot your Pi and try connecting again via VNC. Block Blast
