Micro HDMI power to converter

I have an old VGA monitor, and uave sucessfully attached to my old laptop HDMI port using an HDMI to VGA converter. However, on my Chuwi LabBook Pro the screen is intermittent and very weak. I suspect that the converter chip built into the connector relies on power from the HDMI connector. Is there a confituration option to set the supply power onto the microHDMI port?
