Blurry VGA display on Intel HD 630

I just opened my brand new https://www.acer.com/ac/en/US/content/model/DT.B7YAA.002 Acer ATC-780-UR12, running Windows 10 (64-bit) and integrated Intel HD 630 graphics card.

The graphics card has an HDMI and a VGA port. My HDMI monitor has no problems. My VGA monitor, on the other hand...

Text is blurry. Images have a fade/shadow on the right - like a cartoonist's representation of motion. Open windows, regardless of size or position, have a red-lined left border and a green-lined right border.

I have tried rebooting with only the VGA monitor plugged in. I have tried two different VGA monitors. I have set a custom aspect ratio of 100%.

I tried installing the latest https://downloadcenter.intel.com/download/27267/Graphics-Intel-Graphics-Driver-for-Windows-15-40-?product=80939 driver, but the installation failed: "This computer does not meet the minimum requirements for installing the software".

I have attached the SSU information. Also:

A new error on that one:

"The driver being installed is not validated for this computer. Please obtain the appropriate driver from the computer manufacturer."

That did enable me to install the newer driver, thanks.

Unfortunately, the VGA display problem persists.

DP-to-VGA converter on the processor ports is supported using external dongle only, display driver software for VGA dongles which configures the VGA port as a DP branch device.

If i understand that correctly there must be some extra hardware on your motherboard that is not made by Intel, but by Acer.

I would ask at www.acer.com/ac/en/US/content/support if that can be fixed from their side (potentiometers settings, whatever).

I am assuming there was some physical problem with the hardware. I had a new one shipped out and it works fine.

Thanks for taking the time to help with this!
