Dear Friends., I am working on a Lenovo YOGA 910-13IKB. It is working fine, no problems at all. Today I was connecting to a External Display through the USB-C HUB, it could not connect. (This Lenovo model has only 2 USB-C Port, no HDMI, so has to be connected through a External USB-C HUB). I have changed the setting to External display but still no luck. Re-loaded Windows 11, assuming that the software might be faulty & still same. I know my USB-C port HUB is 100% good (HDMI, USBs, SD Reader) as I use this on all MacBooks & even my buddy has another HUB, still cannot connect to External Display. I updated the GPU drivers, no luck out here too, I replaced the Parad chip PS8743A, as I saw that PDF of this chip, it has video buffering signals too. Am I doing something wrong or the motherboard has a problem?? Thanks in advance.
