Support for high resolution and scaling via VNC is available.
No VNC clients currently offer full 4K support or automatic scaling that aligns with your Mac's display settings. You haven't found a straightforward method to match the resolution and scaling between UltraVNC on your Mac Mini and your Windows desktop. Both systems are configured for 4K displays.
I rely on TightVNC, and the viewer offers different scaling settings such as fit or 1:1 pixels. Are those the options you need? If resolution scaling is active in Windows, it can cause issues. I often have to set an exception for VNC so it shows true pixels.
UltraVNC supports pixel scaling too. You're aiming for a Mac setup that aligns with its scaling settings. When you set the VNC resolution to a high setting, the OS on your Mac doesn't adjust accordingly, resulting in a much smaller menu bar and other elements compared to what the native display would show at the same resolution.
I'm not sure about what you mean. Images might help clarify things. I used UltraVNC before switching to TightVNC for different reasons. They all essentially work the same way—what appears on the host should show up in the client. To change the appearance, you need to adjust settings on the host separately from VNC. One reason I prefer VNC is that it feels like you're directly connected to the system. The account and settings stay consistent. I'm not very familiar with Mac's setup, but I don't like Windows Remote Desktop because it creates a virtual display that doesn't match the real one and often causes issues. Is this similar?
The Mac UI scaling issue means objects don’t adjust to the display size. It’s similar to Windows where you can set the interface to 150% on a 4K screen so icons and text stay readable. With VNC connections, the client maintains 100% scaling regardless of the screen resolution, which is different from macOS where control over scaling percentage feels limited compared to remote clients.
