Cannot get Panel to Display

[mtthll52@gmail.com]

I have a 1920*480 display which is currently connected to my PC but I am unable to get it to display anything. 

It appears to power on but I only get a black display. 

Here is the display I am using: https://www.ebay.com/itm/8-8-Long-Strip-HSD088IPW1-B00-HDMI-TO-MIPI-1920-480-Monitor-Case-Aida64-Display/143785453538?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649

Any ideas or help is greatly appreciated!!

My mini-HDMI connection is going from the LCDs board to my video card (5700xt).

My main display is working properly and Windows can detect the display and shows it as a second monitor.

However the LCD display is blank / black

Does the board have the necessary input power supplied?

If you scroll down your screen where you are looking at display options, do you have Extend desktop selected under multiple displays?

My apologies for the long delay in response. It has been a while since I've been able to reattempt this. 

I have a mini-HDMI to HDMI cable plugged into my video card. The display is recognized with the correct resolution. 

The power cable is mini-USB which I have plugged into my motherboard. I figured this would supply necessary power.

I have also attempted to Extend the displays. When I extend the display the  resolution of my main monitor changes to the resolution of the 1920*480 panel but the panel still remains black / no display. 

I have tried this with two different panels and boards with the same result. Any ideas?
