I use a Rasberry PI4 with 2 RDP session, one per Monitor via HDMI cables
I use a Windows 10 laptop to connect the Raspberry Monitor2 via ThightVNC 2.8.63
with 5901 port
The connection is correct but i have lag on the laptop (via Lan or Wifi), freeze or slow-down
visualization of an Excel file with a macro that updates one of the data in real time
the problem is only via VNC, no problem on the screen in HDMI
What is the best client Vnc for Windows compatible to connect to the Raspberry ?
I don't see any options to Raspberry or client side to optimize refresh rate ?
Lag on VNC connect to the Raspberry
Re: Lag on VNC connect to the Raspberry
VNC is a trivial protocol for remote administration. We never tried to make it as fast as physical display. There are no settings to tune VNC in wtware.
There is our own remote administration protocol in wtware: http://wtware.com/docs5/config.html#wtrc
WTRC should be faster than VNC.
Also, Windows Server still supports native Remote Administration over RDP session. It should be faster than everything because the same image is sent to client and to remote admin. But now it's hidden deeply into server.

Re: Lag on VNC connect to the Raspberry
Hi,
The RDP session is already open on a Raspberry, connected to a local screen via HDMI
I don't need to administer remotely, just display the screen content on an external laptop Windows pc in real time
If I open an RDP session on the laptop, the Raspberry session close, how can I duplicate the display on a laptop in addition to the local Raspberry session ?
Thk

Ask Google about Remote Desktop Shadowing. In 2000/2003 servers it was trivial, but later Microsoft hid this mode to some non-intuitive places. But it's still working. With session shadowing, Windows server sends the same image to both. With VNC/WTRC, Windows server sends image to Raspberry, Raspberry unpacks, then packs again and sends to VNC/WTRC. Unpack-pack-resend takes some time.
Did you try our WTRC? In Raspberry wtware config:
On laptop, install http://wtware.com/newwtrcversion.html , then open Raspberry IP in Web browser. From terminal web-interface, "Remote control -> control this terminal"

Code: Select all
