GTi14 Ultra Thunderbolt 4 Problem (PD and DP not working together)

vitasonline

support1 I use the same cables with T9 and GTi14 !
But in T9 it works power delivery + display port at the same time, and in GTi14 only power delivery works

vitasonline Hi there,

It might the cable incompatibility issue.
When we use an all- in-one cable , it works with power delivery + display at the same time.

Hi Can you recommend a cable that is compatible?

I tried different cables and bought UGOURD Thunderbolt 4 Black 40G 240W 8K which has a PD chip and is defined in the E-marker cable as 0×315C vendor. But no cable displays an image.😂

I updated thunderbolt chip firmware on my GTi14 155H with T105-BIOS firmware and finally now my monitor Arzopa Z1RC works through one type-c cable!!!

vitasonline Glad to hear that 🍻

i would like to know exactly how to update thunderbolt firmware, as my thunderbolt port shuts off sometimes (after restart or shutdown) and seems like not much i can do to get it running again. I’ve tried a few different usb drives and none show up in the boot menu to boot from.
I followed the tutorial on how to put the files on the usb drive and nothing is working for this port.
