I just purchased a Razer Blade 16 (RTX 5080). I’ve enabled the Dedicated GPU mode via BIOS MUX, connected an external monitor via Thunderbolt 4 with a VESA certified DisplayPort 1.4 cable, but the monitor is not being detected. Is there any BIOS or EC firmware update available or upcoming to resolve DisplayPort output recognition from the dGPU? Or is it only me experiencing this?

    I imagine it’s because thunderbolt is unique to Intel as I understand, thus the usb C ports on the AMD model are not transferring video.
