If after upgrading to Windows 10, your windows 10 can’t detect your TV, it might be due to a faulty driver or incorrect settings. Here’s how you can fix this problem:
But, before you try out these solutions, make sure that your TV is connected properly to the HDMI port.
Just unplug the TV and then plug it back into the HDMI port.
Or try plugging in the TV with a different cable. This might work for you if the problem is caused by a broken HDMI cable. Otherwise, try out the following solutions.
Solution 1: Checking the Display output settings:
- Select Personalize after right-clicking on the desktop.
- On the bottom left corner click Display.
- See if you can view the TV as a second monitor.
- If you can’t, press the Win+P key.
- On the popup menu to the right, click Duplicate
- If that doesn’t work select Extend, this should allow you to see the TV again.
Solution 2: Updating the display Driver:
This issue occurs if the Windows Basic driver is installed in your computer. This problem can be fixed by going to the Device Manager. Just click on Microsoft Basic Display Adapter under Display Adapters.
Follow these instructions to update the Device Driver:
- Select Update Device Driver setting by right clicking on the device name.
- Click on Search automatically for updated driver software. Windows automatically searches and installs the new device driver.
Sometimes Windows does not provide the new device driver so you may have to download it manually. If your computer is branded, you can download and install the driver from the manufacturers’ website and search for the latest Windows 10 driver.
