People are stilling problems with Thunderbolt 3, me included and this old post needs updating.

Please post if your TB3 Port is working on an Asus laptop or if you have a solution.

Hello,

     I have an Asus GL702VS, Win 10 Pro, Laptop. I am trying to connect an ASUS PA32UCDM 4k 32" monitor via a Thunderbolt cable as a third monitor.

The laptop is TH3. I have two HDMI Monitors connected and they work fine.

When I connect a regular USB non video cable to the TB port, the port works well for data only.

PROBLEM: When I connect up the one 4K monitor via a thunderbolt cable to the same laptop port, all the screens freeze. The 4K monitor is detected but no video.

TH drivers and all other drivers are up to date. According to all specifications I can connect up to 6 TB monitors.

I do not what the problem is or how to diagnose it.
How can I test a TB3 port ?

Need help
