Windows 8.1 HDMI output not working at all

Anonymous

Hello,

I recently purchased a new laptop with Windows 8, which I had never tried before (so I am new to this). I updated to 8.1 the other day, and afterwards I tried connecting the laptop to a brand new LG HD TV through the HDMI ports. I opened the "Project" menu and selected "Duplicate", and while I see something change on my laptop screen (it flickers, and the resolution/colours change), the TV picks up no signal.

The HDMI port on the TV is working correctly (tried it with another device), and so is the HDMI cable. There is some sort of connection happening because the TV enables the HDMI input only when something is detected on the other side of the cable.

I have seen that it might be a known issue with Windows 8.1, but I can't find a solution anywhere. My laptop has an integrated Intel GPU as well as an nVidia GeForce 740M, and I thought perhaps the problem was that it uses the Intel card as a standard, only switching to the nVidia when necessary, but the HDMI is "controlled" by the nVidia. So I've tried disabling the integrated GPU (to no avail - it just switches to the Microsoft Basic one rather than to the better card - this has been checked through dxdiag), as well as uninstalling and reinstalling the nVidia drivers (which were up to date to begin with). I have checked the BIOS to see if I could change the priorities, but there was no option like I see on my Windows 7 desktop.

Is there anything else I can try? It seems really silly to me that I cannot use the HDMI output at all!

Thank you for any help.

Hi Nicholas,

Thank you for the updates.

Since the issue persists, you may try the following steps and check:

Method 1:

Please follow the steps given below to uninstall the display driver.

a) Press Windows key + X key when you are at desktop.

b) Select Device Manager.

c) Find and double-click Display driver from the left panel to uninstall.****d) Right-click the device, and click Uninstall.

e) Windows will prompt you to confirm the device’s removal. Click OK to remove the driver.

f) After the uninstallation is complete, reboot your computer.

After you have successfully uninstalled the driver, please go to the computer manufacturer’s website, download the Windows 8.1 display driver for NVidia and check.

Method 2:

You may also check with LG support to see if you need to install any firmware updates for the TV.

You may also try running the Windows Updates and install all the available updates including the optional driver and firmware updates.

Did the system restore, it did the trick. This is with a Windows 8.1 computer. I can't find the specific upgrade that did this, but it was an automatic upgrade I did on september 9. There was nothing else done this day. other than "Windows Update", so that IS the problem. I hope this helps anyone!

Thanks bro..

Another solution I have found that

Some graphics cards have their HDMI port a little loose (cant observe).

So put your HDMI plug very tightly in the GDs HDMI port it will

100% work all time.

Boot your laptop from Safe Mode.

Uninstall all the graphics related drivers with their software.

-> To do that go to device manager. Right click on your graphics device (for ex. Intel HD 3000)

-> Click on Uninstall, if asked check "Remove software as well".

Restart your computer in normal mode and having your internet connection ON.

Your OS will automatically installs suffice driver for you.

now go to intel's site for downloading new drivers ( even if your OS has installed it again download it).

Install it. Plug out your HDMI cable while PC and OS is running.

again plug in your cable.

Its done.

ATTENTION ALL DUAL DISPLAY PC OWNERS WITH ISSUES.....MICROSOFT IS ROLLING OUT "THEIR PERFECT FIX"!!!!!

Well, after accepting that MS will never accept responsibility for this issue and give us a resolution...I found that I am WRONG! MS has been very diligently working on a perfect solution. Very shortly they are rolling out "their" fix. Now that they have taken our money, screwed up our pcs, gave us no support, and turned expensive power pcs into crippled pieces of ****...this is the update we will are receive shortly...

"Here at Microsoft, we care about the acquisition of 100% satisfaction from our customers.

We apologize for any complication that others have caused you, and hope that this resolution, will bring your faith back to supporting Microsoft blindly since we had never once rolled out a damn thing that worked properly.

Sincerely,
