I can't get HDMI to work on my Acer B247W Monitor
VGA seems to work fine. I'm actually using an adapter to connect from the VGA connector on the monitor to a USB-C connector on my laptop. But I'm having trouble getting the HDMI connection to work.
When I connect using ONLY the HDMI cable, the monitor display is blank and the menu settings on the back of the monitor don't work.
When I connect using BOTH the HDMI AND VGA cable, looking at the monitor menu settings, it indicates VGA as the input (Auto Source is ON). I then manually set the input to HDMI, the screen goes dark for a few seconds and automatically reverts the input to VGA. I turn Auto Source OFF and change the input setting to HDMI, I get a blank screen and menu settings don't work again.
How do I set the monitor to use HDMI?
