Hi,
I’m using the Power Panel that uses Windows 11 as the operating system. Previously, I had no issue with this hypervisor thing, but not with this one.
HMI response is so bad, my momentary button does not respond as usual (refresh rate is already 100ms).
What I’ve done is change the VNC client to another lighter VNC client, and it’s better, but still not as good as usual. If I change the color to 256 or even lower, it’s better but the image becomes ugly.
Thanks
Hi @Heru_Prayogo ,
if you have 2 identical systems, same HW and same SW installed (drivers, BIOS, AS prj, Windows version) there is no reason to see different performance.
Are you sure, on Windows 11, you have installed the same upgrades?
Thanks
Ciao

I’m using PPC3200 that already comes with Windows 11 and I’m not change any software installed on it. So I think it’s already the best setup of SW and HW.
For the hypervisor it self, I set the DRAM on 1024 so the Windows still have 7Gigs, I think it is low.
What I didn’t test yet is using B&R VNC Client, but I can’t find it on my installation folder, even on B&R Download section.
Hi,
How is the CPU load of your Automation Runtime?
Which VNC viewer you’re using?
If the CPU load is “high” (not much idle time), this can cause VNC lag / update because VNC does not have a high priority inside the system.
Depending on the VNC viewer, please check the connection properties.
In most of the VNC viewers, you can change settings like “connection quality” and/or “picture quality” (le.g. “low/medium/high”), which can influence the way how the client is comunicating to the server: on a direct connection like yours, always set “XXX quality” to “high” to switch off any internal bandwidth limiter or similar.
If there’s a setting named “(preferred) encoding” or similar, try setting this parameter to “raw/uncompressed” and check for changes of the behavior → every other encoding (e.g. ZRLE2, others) could influence the refresh behavior of the client, and could advice the server to compress the image data before sending it which could slow down the performance on server side.
Best regards!
hi @Heru_Prayogo what is status of your topic? can you provide answer on question colleagues asked you for?
I think it’s not fully related to how I configure the VNC itself, because after I checked again, even operating the Windows OS directly already feels not really smooth.
Right now I’m using the B&R VNC Client. The tool is already quite old, but I think it’s still the lightest one. I’m using tight encoding without reducing the image compression quality.
Best regards!
At the moment, I still don’t have the best solution for this issue. Later I want to discuss it with my team about the possibility to move into ARembedded instead of using Hypervisor with Windows 11, since in this HMI we are not using any third-party application.
Best regards!
