I did post this in response to another user's query, so my apologies if I am not following protocol by posting it separately.
Notebook Model: ASUS UX330UAK - Windows 10 64bit
Graphics Driver: Intel(R) HD Graphics 620
Driver version: 18.104.22.16886
Driver Date: 2018-08-15
My laptop is not able to detect *most* external displays. I have updated all my drivers from both the ASUS website and then tried the more recent ones directly from the Intel site. I've also tried doing this after a clean install of Windows 10.
I want the notebook to detect most or all external displays easily detected by other notebooks, but I am particularly interested in having it detect and extend the display to an HP Pavilion 27xw monitor. I have tested other laptops on this monitor using the same micro HDMI to VGA adapter and VGA cable, and they extend the display properly. Strangely, I used this same cable setup in my micro HDMI port and managed to extend the display to a Dell monitor (which is not mine), so I know that the micro HDMI port on my notebook is not the issue.
I have spent hours on this, and have read many suggested courses of action online for generic 'cannot detect external display' problems. One course of action which seems to be available to some people but not others is to 'Detect' another display in the Display Settings utility, have Windows not find it but nonetheless bring up a picture of a second display that it hasn't detected, and then manually force through a signal. When I hit 'Detect', my notebook simply says another display was not detected and does not generate a picture of a second undetected display that I can work with.
Any help would be greatly appreciated!
Thank you for joining this Intel Community.
Because you are using an HDMI* to VGA adapter, this issue must be a computer limitation. However, please follow these steps to continue troubleshooting it.
1. Perform a clean install of the graphics driver in case of system conflicts.
1.Disconnect your unit from the internet.
2.Uninstall both the Intel Graphics driver and the Intel Display audio driver. To do this, please follow the steps on the link below under these sections:
-Uninstalling the Intel Graphics Driver via the Device Manager Method
-Uninstalling the Intel® Display Audio Driver or the Intel® HDMI Audio Driver via the Device Manager Method.
3.Restart your computer. Go to the device manager and check if Windows installed another version of the graphics driver. If it does, please remove it and restart your computer one more time. Repeat the process until you get the Microsoft Basic Display Adapter.
4.Once you do, install the latest graphics driver provided by your system manufacturer.
**Please confirm the system model and operating system.
5.Once the latest driver has been installed, you may enable the internet connection again.
If the issue persists, you can also:
1. Try another HDMI* to VGA adapter for testing purposes.
2. Install a monitor driver if available.
Please run the Intel® System Support Utility and attach the report to this thread.
