HDMI not working - not connecting to a second screen

[linda1232]

Hi, I have an HP Pavilion x360 Convertible,

Product Code: Y3X17EA#ABZ

[personal information removed]

After windows 10 update, I cannot connect neither a second screen, nor a tv, via HDMI, while before I could do that with any problem. I have already tried all the possible updates of drivers for any component and also tried a rollback of the drivers to a date previous to the windows 10 update.

Please help me!!!!

Thank you very much for your help.

Hey there! @linda1232, Welcome to HP forums.

I understand your laptop has stopped detecting the second monitor.

Don't worry I'll try to help you out.

Did you make any changes to the monitor?

Are you trying to extend, mirror or duplicate the display?

How are the monitors connected?

What cables are used to connect the monitors?

Have you tried checking with different HDMI cables?

Please provide the product number of your PC to assist you better.

As you mentioned after updating the window the laptop has stopped detecting the second monitor.

I appriciate your efforts for trying out the steps before reaching out to us.

Use the following instructions to either extend or duplicate the desktop with a second monitor:

1. Right-click anywhere on the desktop.

2. Click Display Settings.

If only one monitor is showing in the window, first verify that the connections are secure between the monitors and the computer. Then, click Detect. If Windows does not recognize both monitors, click Identify. The numbers 1 2, or 3 are shown on the monitor icons to help you identify the monitors.

If Display, Resolution, Orientation, or Multiple displays selections in the Screen Resolution window are dimmed, not allowing you to make the desired changes, see; Configuring the display with the display driver.

3. Use the Multiple displays drop-down list to select one of the following options:

• Duplicate these displays: Show the entire desktop on both displays. 

• Extend these displays: Stretch the desktop across the two displays.

• Show desktop only on 1: Use only display 1 and show nothing on display 2.

• Show desktop only on 2: Use only display 2 and show nothing on display 1.

4.(Optional) To change the direction of the desktop extension (usually left or right to match how the displays are physically positioned), select a monitor and drag it to the desired position.

5. When done, click Apply.

Hi,

I already tried all the solutions you proposed but nothing worked. I am also trying to update the driver from the Intel site but the installation cannot be completed because apparently the drivers I need should be asked directly to HP.

My product code is Y3X17EA#ABZ.

@linda1232, Thanks for your quick response and time.

I appriciate your efforts for writing back to us.

As you mentioned the issue still persists after trying out the steps.

Have you tried checking with a different HDMI cable?

You did a Marvelous job by trying the steps recommended previously.

However, there are few more troubleshooting steps left, please try those and let me know how it goes.
 

Try updating the BIOS and graphics driver from the link below.

Update the BIOS using this link: https://ftp.hp.com/pub/softpaq/sp85501-86000/sp85563.exe

Update the graphics driver using this link: https://ftp.hp.com/pub/softpaq/sp85001-85500/sp85391.exe

After updating the drivers try the steps recommended below.

• Open a Run prompt
• Type the following and click ok: desk.cpl
• Select the second monitor
• Choose "Extend these displays" from the Multiple Displays drop-down

If the issue still persists after trying out the steps, It could be an issue with the HDMI port on your PC which could have gone faulty.

I will share you few details in a private message. Please watch your inbox for more information.

Please mark my post as accepted solution if you feel I have answered your query.

Hope this helps!

Take Care! 🙂
