Question Windows 10 won't recognize second screen from HDMI

[COLGeek]

So, the L1940 is connected via VGA from the PC's VGA port to the L1940's VGA port.

And, the TV is connected to the PC via HDMI, to a DVI adapter, connected to the TV (what is the make/model of this TV?)

Is this correct?

Yes, that's correct. The TV is a UVSH Philips Flat TV. The dual monitor functionality is working in Linux but not in Windows.

Understood. Seems the Windows drivers are having trouble with the DVI adapter/HDMI cable connection or with the refresh rate on the display.

Is this the TV?

It's an older model, this one.

Understood. Seems you need to find a DVI cable and use the DVI port on the PC instead of HDMI/adapter combo.

So I tried connecting the TV with a brand new DVI cable (it just arrived) but the results were the exact same.
