Wow! 10 whole words, no really eight words and two letters. Would you care to explain your problem in a little more detail please? There are plenty of members here willing to help if they knew more about your problem. Do you have screenshots maybe?

@Dominospizza Did you plug the display into a charger or powered USB hub?

I believe that you need to supply power to the display from a source other than the phone.

I connected to directly c type display port. And my iPad work but only my phone doesn't work

[LongHiker]

@Dominospizza Well, you need to connect external power to the display and give it a try.

[Dominospizza]

Yes I did it but still doesn't work.

@Dominospizza Are you using a USB C cable with video capability?

If I use a charging USB C cable, it won't work. But if I use the USB C cable which came with my portable monitor, it works just fine. 

Same result if I use my computer to the portable monitor.
