    After Windows Update KB5048652, Thunderbolt stopped supporting the external HDMI monitor


    After Windows Update KB5048652, my thunderbolt stopped supporting the external HDMI monitor, but it can still support USB devices.Tried updating the Graphics driver can't help. Found some document online to change the ''Power Settings'' ->> Disable the USB selective suspend settings. But unfortunately that option is not available on this laptop.My laptop is ACER / TPM214, with IntelR IrisR Xe Graphics driver: 32.0.101.6734After I uninstall KB5048652, my thunderbolt port can support the external HDMI monitor...However, due to company policy, KB5048652 will be updated automatic
