X360 on Win10 Mini DisplayPort not detecting any VGA monitors

[Jsreidnyc]

I have an original series HP Spectre x360 13-4003dx with Windows 10. I cannot connect a vga display to the x360 Mini DisplayPort. I am using a miniDisplayport to vga cable from CableDeconn. Typing (Windows) + P, I try to switch to dual displays, either mirrored or extended, and also try to click on "detect display" but get the error message, cannot detect.

i have rolled back the graphic drivers to the original install, and also updated to the most recent. Neither works. I also removed pin 9 from the VGA side of the cable (15 pin cable, reduced to 14 pin).  I removed the pin because I heard that some cables send voltage thru that pin, and shouldn't. Nothing works.

i have tried it on a Planar vga only monitor, a Samsung VGA monitor, and an LG TV (vga connector), all of which work with other equipment. 

The hdmi to hdmi connection works just fine.

i have spent hours and am very frustrated. 

Any hints or help is  greatly appreciated.

I'm about to go to the dark side (Apple). Please don't let me do it! Everything works so much easier (but with less flexibility and sooo much more money).

Hi @Jsreidnyc, 

Thanks for the post and Welcome to HP Forums. 

I see you are not getting any display using the miniDisplay port to VGA adapter. Kudos to you for checking the monitor with other computers. 

Have you tried to install the display driver directly from the graphics card manufacturer's website? 

Recommend you to check with miniDisplay port to VGA adapter for any additional driver that might be needed for the adapter to work. 

The display ports on the computer are plug and play, that means if you connect a monitor that has a miniDisplay port directly or HDMI, the monitor should be directly detected.

Open device manager and check under monitors and also look for unknown devices. If you find any unknown devices, right-click on it and check for drivers.

If the device is not listed under monitors in the device manager. That means that adapter is not working or might require an additional driver. 

Recommend you to check the miniDisplay to VGA adapter manufacturer for any driver and also check for its compatibility with Windows 10. 

Also, perform a Windows update with the adapter connected to check if Microsoft can detect the adapter and install the required driver automatically. 

You can refer to this article for using additional displays, Microsoft forums post (tough the article is titled Surface pro, the procedure is the same for other notebooks) and 

Let me know how it goes.

Thank you for your quick response. 

Ive done the items below, but still am not able to connect my VGA monitors to the Mini DisplayPort connection.

i checked the driver, none showed as needing updates, or unknown errors (no yellow triangles with <!>).  In fact, the website cable says that no drivers are needed or supplied.

i tried booting with everything connected to see if that would flag something, but there was no change.

in device manager, it shows just one monitor, pnp generic monitor, with no update needed. I was hoping at least it would show an asterisk next to a unknown monitor, but no.

I went to system updates, and it allowed me to update a LAN update and to re-update the intel 5500 graphics from the rollback. I did both these updates with the Mini DisplayPort cable plugged in to the laptop and a monitor. Still no display, no change she in notifications, and no 'detected display' message when run.

i rebooted several times, hoping it would take, to no avail.

any other ideas?  The laptop exhibits no signs of trouble or damage, it is relatively new and hardly used.

Hey@Jsreidnyc,

Thanks for the response.

Have you tried a different adapter cable for VGA to Display port?

Have you checked the Adapter you have on a different PC to check if that gains any video signal?

It seems to be a hardware issue where in the Display port to VGA adapter might be malfunctioning.

Hope this helps. Please share for more assistance.

Thanks for your help. Such a simple solution. It was a faulty cable. I replaced it and all is well. Thank you all for your quick replies.
