我用 U3219Q, 平時一條 USB C 線做曬所有野。
最近個 Mon detect唔到 video 信號，但幫laptop差電、USB Hub (Mouse KB) 繼續用到。
我暫時用多一條 HDMI 頂住。
請問有冇soulution？

I have same experience as your case, Type-C display function lost signal for sometimes.... finally i disassembly the case and find Type-C connector (SMT type connector, without any mounting legs to enhance soldering on PCB) with fake soldering... some connection pins for the Type-C connector cannot connect to PCB well.

Wow! Just wow!
I guess hardware repair is a bit too much for me at this point. Haha.

Have you tried using another USB-C cable? I once have problem with the cable.

回覆 3# deardaniel2000 sorry 睇錯, 應該係講你部notebook 有冇 bios update, 我有部hp notebook 有兩次都係咁, 搵番hp bios 有update, update 完ok

試過了好多條線。
個port可以差到電，過道mouse signal，就係有一日突然video 過唔到
