HD 4000 Laptop & External VGA Monitor - Black Screen

Specs as follows:

Asus X501A w/ i3-3120m (Intel HD Graphics 4000)

Win10 Pro 1607 (14393.447)

Driver version 10.18.10.4425

Problems:

*With external VGA monitor connected (tried Benq T221WA & G2220HDA), monitor receives signal, but remains black.

*Without external monitor connected, ghost monitor named "Generic Non-PNP Monitor" persistently detected in Device Manager.

*In Advanced Display Settings, the ghost monitor's resolution mode is limited to 1024x768 & 800x600.

*Attempted to force manual display resolution in Intel Graphics utility, also tried reverting back to older driver sets, to no avail.

Both built-in LCD panel & HDMI are working normally, external VGA used to work normally back in March of this year.

Not sure if it is a Win10 1607 Anniversary Update issue, 10.18.10.425 driver issue, outdated BIOS, or perhaps some unknown hardware defect during that time.

Thanks & any help appreciated.

Hello lonnie.chang,

 

 

Thank you for contacting the Intel community.

 

 

Your best support will be with your Laptop manufacturer as they are more familiar with your system and how the components interact with each other.

 

 

However, you may want to try the following:

 

 

Run Windows® update and make sure the system is up to date and update your BIOS and for this you will need to contact your system manufacturer.

 

 

You can try our Intel generic driver, you can download it here:

I suggest you to uninstall the old driver first and the reinstall this generic driver manually.

If the problem persist, try different VGA cable, if you have another spare VGA cable that you can try we can determine if the issue is with the cable or not. If the issue persists with different cable try different monitor if it is possible or try using another PC with this monitor. If this works, the laptop may have a physical damage in the motherboard.

 

 

 

I hope this can help.

 

 

 

Regards,

 

 

 

Ivan.
