No signal from PC to TV using HDMI

[Harnigel]

Hi,

)

When I connect my HP to my Sony Bravia TV using HDMI, I get no signal.

My TV just shows the message  "Unsupported signal. Check the device output" on the screen.

Apparently my HP can find the TV, as the HP shows "SONY 50%" when I hold my cursor above the sound icon.

My Hp do not appear at the HDMI device list on my TV, so it seems as my TV can't find my HP.

The HDMI cable is working find, as I can use it with an HP dv7-6110 (upgraded to w10 from w7) connected to the same TV without problems.

Both HP's are updated to W10 version 1709.

The screen solution is 1366 x 768.

I have tried all HDMI inputs on my TV, without any luck.

The screen on my HP is configured to dublicate.

I think I have been through all the settings i can imagine, but I still haven't found a solution.

I hope somebody can help me....:smileywink:

Regards

Hi @Harnigel

Welcome to HP Support Forums. A really great platform for posting all your questions and finding solutions.

I understand that you are unable to connect your HP Notebook to your Sony Bravia TV through the HDMI

I could help.

I suggest you check for any Windows updates and complete them.

Start  button, and then go to Settings  > Update & security  > Windows Update, and select Check for updates. If Windows Update says your device is up to date, you have all the updates that are currently available.

Also, try updating the Graphics driver from the device manager.

- In Windows, search for and open Device Manager.
- In the list of devices, look for Display Adapters and expand the list
- Right-click the driver and select Update Driver Software.
- Click Search automatically for updated driver software.
- Follow the on-screen instructions to install the updated driver.
- Restart your computer to complete the installation of the updates.

Then update the BIOS from Here

Keep me posted how it goes.

Thank you. 🙂

It looks like you were interacting with @KrazyToad, but he is out for the day & I'll be glad to help you out, 

I'm the Riddle_Decipher & I'm at your service. 

I reviewed your concern and the entire conversation, did some research and here's what I recommend:

(I'm sure I can't speak your language fluently as you would, so don't worry about your English, you are doing just fine).

Now that, we have that out of the way, I wanted to know if you've lowered the resolution of your laptop to check if that works on the TV as well,

Also, does an alternate laptop work with the TV or have you checked with an alternate HDMI cable to see if that works?

While you check that out, please follow the below steps:

When connecting your computer to an HDMI device, such as a monitor, TV, or surround sound speakers, you might encounter display or sound issues. Use the information in this document to check your settings and to troubleshoot specific problems.

Hi,

Thanks for the response.

I've tried all the possibilities i have for changing the resolution on my HP, but It still doesn't work...

I've also tried to connect a HP dv7-6110 notebook 17" screen to my TV with the same HDMI cable. This has been working fine for years and still do.

I connected my HP to another TV (Philips) with the same cable, and it didn't work either.

At last, I tried to connect my HP to the TV with a brand new HDMI cable, but still no picture on my TV.

Hi,

Now I've talked with the HP Support in my country about my problem with the PC - HDMI -TV.

You wrote they could remote into my computer and try to sort it out, but they did not mention that possibility at all.

Instead they recommended me to make a full system restore and then update my W10 updates and after that update by the HP Support Assistant.

They told me to keep an eye on the updates and I should try to connect the HDMI cable sometimes between the updates, to see if I perhaps could find an update causing the problem.

Now i am strongly considering if I am going to do the full system restore - I have to be very sure to have the right full back up all my photos, videos, music and especially programs and licenses etc. Quite a job...

But the only alternative I can see is sometheing like ChromeCast, but of course I prefer to use my computer the way it was ment to be used.

Hi @Harnigel

I see that you have already spoken to our Phone Support. If they have suggested the Recovery, it is probably because the OS is corrupted.

Please make sure to backup all your personal data before attempting the Recovery.

You can try these steps for System Recovery.

- Turn off the computer.Disconnect all connected devices and cables such as Personal Media Drives, USB drives, printers, and faxes.
- Turn on the computer and repeatedly press the F11 key about once every second until the Choose an option screen is displayed, and then continue.
- On the Choose an Option screen, click Troubleshoot.
- On the Troubleshoot screen, click Recovery Manager.
- Under Help, click System Recovery.
- When Recovery Manager prompts you to back up your files, select a backup option:
- The Welcome to HP Recovery Manager screen is displayed. Read the on-screen information, and then disconnect any connected devices and cables, such as Personal Media Drives, USB drives, printers, and faxes.
- Remove media from internal drives, and remove any recently added internal hardware.
- Click Next to continue.
- When recovery preparation is complete, click Continue to proceed to the installation phase of the recovery process. The computer restarts several times during the recovery. This is normal. Do not close, shut down, or disconnect the computer while HP Recovery runs.
- Recovery Manager reformats the Windows partition and reinstalls the original software.
- After the system recovery is complete, click Finish to restart the computer. Complete the setup screens and wait until the computer finishes the setup.
- Once the setup is complete, turn off the computer, reconnect all devices and cables, and then turn on the computer.
- Before using the computer, update and protect your computer by reinstalling any virus and security software that was installed before the system recovery.
- Reinstall any software programs that were added after purchasing the computer, as well as any files that were backed up.
 

Thank you.
