Fix Windows 10 Not Detecting HDMI TV Issue
After you upgraded to Windows 10 or performed a Windows 10 update, if Windows cannot detect your TV, don’t worry. You’re not alone. Many Windows 10 users are reporting this issue. The good news is you can fix it with one of the solutions below.
First of all, ensure there is no problem with the HDMI port and the cable:
1) Unplug the TV then plug it to the HDMI port again. Then check to see if the problem is resolved.
2) Try using a different HDMI cable
A broken HDMI cable can cause the problem. Try using another cable, and see if the issue persists.
If there is no problem with the HDMI port and the cable, try below 2 solutions. You may not have to try both of them. Try Solution 2 if Solution 1 doesn’t solve the problem.
Solution 1: Check the display output settings
Incorrect display output settings could be the cause of TV not detecting problem. Follow steps below to check for it.
1) Right-click the desktop and click Personalize.
2) Click Display .
3) Check if you’re able to see the TV as a second monitor.
If you are not able to see the TV on the screen, follow steps below:1). On your keyboard, press the Windows logo key and P at the same time.
2). Click Duplicate.
If Duplicate doesn’t work, try switching to Extend.
After that, check to see if Windows can detect your TV.
Solution 2: Update the graphics driver
The problem may be caused by graphics driver issue. It would occur if the Windows basic video driver is installed.
You can go to Device Manager to check the status of the display driver. You may see Microsoft Basic Display Adapter under category “Display adapters” (see below screenshot). In this case, you probably can solve the problem by updating the driver.
You can update the driver manually. But if you don’t have the time, patience or computer skills to update the driver manually, you can do it automatically with Driver Easy.
Driver Easy will scan your computer and detect any problems then provide you with all new drivers you need. You can update the graphics drivers with the Free or the Pro version of Driver Easy. But with the Pro version it just takes 2 clicks (and you get full support and 30-day money back guarantee).
1) Download and install Driver Easy.
2) Launch Driver Easy and click Scan Now. Driver Easy will scan your computer and detect all problem drivers instantly.
3. Click Update button next to the graphics driver to download and install the correct version of this driver (Update the driver step by step with the Free version).
Or click the Update All button to update all drivers automatically (this requires Pro version).
Here take Intel HD Graphics 4400 for example. Driver Easy will detect the graphics card installed on your computer.
TIP: After connecting the TV via HDMI successfully, if you can’t hear sound from the output, go to Fix HDMI No Sound in Windows 10 for the solutions.
