Multiple screen display not visible

[JohnMck1]

I've been trying to connect my Pavilion X2 to a projector using a HDMI cable. The projector is seen as an additional screen by the computer, but nothing is showing on it except a message saying 'no signal input'. I was trying the various multiple screen options in the display settings and selected the projector (rather than multiple or extended). My computer screen immediately went black. It returns if I unplug the HDMI cable, but then I can no longer select the multiple screen options to change back to a multiple setting.
Please can anyone tell me how to reset the multiple display setting without having the additional screen plugged in, or otherwise solve the issue?

@JohnMck1,

Thanks for engaging in HP support Forums! This is a wonderful location to converse with the community, get assistance and find tips! I reviewed your post and I understand that you are having issues connecting the projector to the computer.

Don’t worry, we will work together to resolve this issue and It’s a pleasure to assist you in this regard.

To provide you with an accurate solution, I'll need a few more details:

Could you provide me with the exact product number of the Notebook? Use this link to find it:  https://support.hp.com/us-en/document/ish_2039298-1862169-16  (Ensure you do not share any of your personal information such as serial, phone number, email ID, etc...).

Have you tried to check if the HDMI port on this computer works fine with other devices?

Have you checked in device manager for any unknown devices listed?

Have you tried to update the drivers?

Have you tried to check by reducing the screen resolution?

In the meantime, let's try these steps here: 

Right-Click on start button> click device manager> expand display adapters>then select the display drivers that are listed and right-click on it and uninstall the drivers.

Check the box that states delete the software for this device.

Now restart the computer and then update the Bios, Chipset and graphics card drivers on your PC from our HP support website, using this link.

Also, download and install HP support assistant on your PC. It should automatically download and install the latest updates and drivers for your PC.

Dear Jeet Singh,

Many thanks for your reply and assistance. My apologies for the delay in my reply, I have spent many hours trying to sort out this problem.
I have now resolved the issue. It turns out that I have been using a brand new HDMI  cable which is defective, and although it identifies the connected screen, it doesn't send any information to it. All I needed was to change the cable.

Once again,many thanks for your input.

Regards,

John
