HDMI not working after upgrading to Windows 10

Hi I just upgraded my computer a HP Pavilion Dv6 to Windows 10 and now my hdmi won't work does anyone now how I can fix this problem please.

 

Dual Monitor not being Detected Windows 10

I have the same problem.

Just upgraded HP Pavilion Laptop (dv6 is model)

External Viewsonic monitor connected via HDMI.

When I try to look at displays and say "detect" is says "nothing detected"

Worked fine with Windows 7

 

You should start by posting a screen shot of your device manager, but I would be willing to wager you need your GPU drivers. It looks like it has an intel iGPU but there are drivers for both intel and nvidia GPUs, so we would need to determine what your model is equipped with. Run a tool like Speccy and look under the graphics tab to see what adapters you have in your system.

 

To identify the unknown device, go into device manager > right click the unknown device > click on Properties. The Properties window will pop up > click on the Details tab > under Property, click the down arrow and choose Hardware IDs. Now under Value, right click the first line and choose Copy.

Go to Google, right click in Google's search bar and choose Paste. The search results should identify the unknown device.

its not the HDMI

Still dont know what the issue is!

 

That device appears to be the HP 3D driveguard, it's a driver for the accelerometer which locks the HDD spindle when it detects the laptop falling. What driver do you have for chipset/graphics?

No no like right click your graphics adapter, click properties, and click the driver tab and give me the version number Include the driver date too *Biggrin

I googled the Device ID you posted. It looks like it's your hard drive protection software. It's called "HP ProtectSmart Hard Drive Protection". I then Googled the specs of you laptop. It looks like it original came with Windows 7, I'm guessing 64-bit. I then went to HP's website and found the drivers for your computer. First I went HP website > Support > Software & Drivers > entered dv6-2155dx in the search bar > then chose Windows and Windows 7 (64-bit). That takes you to all the drivers for your laptop. The one you are looking for is in Software-Multimedia.

Now remember, if your Windows is 32-bit, you need to choose that. Another thing, this driver is for Windows 7 and may not work with Windows 10.

When I upgraded from Windows 7 to 10, the upgrade assistant made me uninstall the hard drive protector. I never did try to reinstall it after the upgrade.

 

Well considering your unknown device has nothing to do with your HDMI port, you could try a slightly updated driver. If that doesn't work (and it very well may not) then you more than likely have a busted port.

The last drivers made for your device were for windows 7, but the drivers should still install and work fine. This is the last one made for your GPU: Download Intel® Graphics Media Accelerator Driver, Windows 7* 64, Windows Vista* 64 (exe)
You may want to use DDU before installing the new driver as it cleans out the old driver and the registry very effectively.

 

Beyond the Unknown device, still cant get my HDMI to work.

 

Have you tried a different HDMI cable? Did you try the driver Carsomyr found?

The only other thing I can suggest is to test the HDMI port in Windows 7.

Do you have a spare hard drive? You can replace the one now and install Windows 7. If you don't have a spare hard drive you can install Windows 7 in a virtual box.

Another option would be to make a backup image of your entire hard drive. Most people on this site use Macrium Reflect Free. After you created the backup, install Windows 7 and all the drivers. Even if it's not activated, I think it has a 30 day trial period. This should tell you if it's a driver issue or a bad HDMI port.

After you are done with the test, restore the backup image.

 

I sort of already assumed you tried a different cable, but I guess it is worth mentioning Try different cables and try to hook up to different sources (i.e TV, Monitors, etc) but if it fails I would assume the port is bad, particularly if it is a hand me down from someone else...
