[2nd display not recognized]

Anyone have an idea as to why my 5" monitor will only work and display my sensor panel when it is plugged into a regular USB? Whenever I plug my monitor into a motherboard USB header, it doesnt get recognized and will not diplay the sensor panel. I've tried looking all over the internet for solutions and come up empty

[2nd display no recognized when powered off MB USB header]

Title says it all. I can get my 2nd panel to display my sensorpanel when its powered off of a USB that plugged into a USB port on my PC, but when I use a header off my MB the 2nd display is not recognized. Tried restarting the PC multiple times using both connection methods and it will only be recognized when using the "external" USB.

Ideas or fixes?

[No 2nd display when plugged into MB USB header, only when using external USB]

Having a small issue. I connected my 5" display using a USB to MB header so it will turn off/on with my PC, and now it doesnt get regonized even after numerous restarts. If I swap back to an external USB cable, it works.

Anyone got a fix or any ideas?
