5 Reasons Why Your Portable Monitor Shows No Signal

February 3, 2016

Have you ever plugged in your portable monitor to your laptop or other device and received the "No Signal" image? 

 

Don't worry. It doesn't mean you received a faulty screen. 

 

Here are a few reasons why this is showing up on your screen.

 

1. (The obvious) Your HDMI/ VGA/ MiniDisplay cable isn't plugged in. 

 

Two cables are needed to connect this to your screen. If you're receiving the "No signal" image, that means your USB cable is plugged in. Power is being drawn. Now it's time to plug in your second cable.

 

2. Wrong Port

Make sure you've connected the right cable in the right port. Since all the ports are micro. You can easily connect the micro DP cable into the micro HDMI cable.

 

If you're using 1303H, it's the HDMI port first, DP, then VGA. 

This happens all the time. 

 

3. Autosearch isn't on

Sometimes the monitor needs to be told which input source the cable is sending the signal is from. In this case, select the control panel on the monitor and find Input Source. Sometimes if you used a VGA cable last time and now you've switched to HDMI the monitor will still be in the VGA setting. 

 

Select Autosearch. The monitor should refresh at this point and the screen should light up. 

 

If this doesn't work, then select the correct input from the three choices below. The monitor should refresh again. 

4. The cable is loose in the port

In some instances after a lot of usage, the cable might be loose in the port. Try fumbling the cable which it is still connected in the port and see if the screen lights up.

 

5. The port in the monitor is broken or your cable is dead. 

In this case, things get a little complicated. If you're still under our one year parts and labor limited warranty, then send us an email at support@icitouchtech.com and one of our customer service agents will be able to help you out. 

 

If your cable is frayed or the wires are popping out, then it's time for a new cable. You can purchase a new cable from the website shop here
