    Hi everyone,

    I'm running Windows in a Parallels virtual machine on my MacBook Air M3, and I've connected a 144 Hz external monitor. By default, the VM inherits the display's full 144 Hz refresh rate, which causes my MacBook to heat up significantly. I contacted Parallels support, and they confirmed that the VM's refresh rate always matches the host's and cannot be adjusted independently.

    Has anyone here found a way to limit or change the refresh rate for a Windows VM while keeping the Mac's display at 144 Hz? Any tips, workarounds, or configuration tweaks would be greatly appreciated. Thanks in advance for your help!
