NS-24DF310NA19 Fire TV won't detect PC HDMI connection

My Insignia NS-24DF310NA19 won't detect my PC when plugged connected via HDMI cable. The computer detects a second display, but the TV itself says "input not detected" when I try to plug the cord into any one of the three ports. The PC drivers are all updated and I've played around with every possible setting--is the TV capable of connecting to a PC using an HDMI cord? I was hoping to use it as an external monitor...

Good Morning, arsynder.


Welcome to the Best Buy Community Forums! I definitely understand wanting to find technical support on your Insignia television and your laptop. From my former experience as a Geek Squad Agent, I will provide you with some initial troubleshooting steps to attempt. If these steps do not resolve the issue, I would advise scheduling a visit to your local Geek Squad Precinct for further testing.


For any sort of computer troubleshooting, the best practice is always process of elimination to determine the root cause of your problem. Does your Insignia television work using that same HDMI cord with a different device, such as a Blu-Ray player? Is your laptop able to connect to a different external display, such as a monitor or another television, using the same HDMI cable? Have you attempted those steps with a different HDMI cord? 


If you need further assistance, please send us a private message or feel free to schedule an appointment with the Geek Squad.


Kindest regards,
