Windows 10: HDMI splitter blowing up screens after a while

I am using an HDMI splitter to hook up my PC to two TVs. Both TVs work for a while but then one of them blows up. I try after a while and it starts working again. However after a while it blows up again. Is my HDMI splitter too week? what can I do to make it stable.

Dear Dee DR,

Welcome to the Microsoft Community



Thank you for reaching out to us with your concern about connecting two monitors to your laptop using an HDMI splitter. I understand how important it is for you to have this setup working smoothly.

Based on your description, it seems like you're experiencing difficulty getting the monitors to connect through the HDMI splitter. Let's troubleshoot this together:

1. Check Compatibility: Ensure that the HDMI splitter you purchased is compatible with your laptop and monitors. Sometimes, compatibility issues can prevent devices from communicating effectively.
   
2. Verify Connections: Double-check all connections to make sure everything is securely plugged in. Ensure that both HDMI cables from the monitors are connected to the output ports of the HDMI splitter and that the HDMI splitter's input is connected to your laptop's HDMI port.
   
3. Test with Different Setup: If possible, try connecting one monitor directly to your laptop and another through the HDMI splitter to see if both configurations work individually. This can help identify if the issue lies with the splitter or another component. If possible, test with another HDMI splitter to rule out the possibility of a defective splitter.
   
4. Check HDMI Cable Quality: Sometimes, using poor quality HDMI cables can lead to connectivity issues. Try using known-working HDMI cables to rule out this possibility.
   

If none of the above steps resolve the issue, there might be a compatibility problem with your splitter. Consider contacting the splitter manufacturer’s support for further assistance.

If you have any further questions or need additional assistance, please don't hesitate to ask.

HDMI Splitter

A splitter will not work it only shows the same image on two screens.

Your graphic card needs to have 2 HDMI ports.

 

HDMI Splitter

Just a splitter will give you the same image on both monitors.
If your computer has a second output like a second hdmi, vga or dmi port
you can try hooking up the second monitor to that to get your second display.

There are usb to hdmi listed but I have never tried them.
