I have an Acer SB220Q for work, and it worked perfectly for a while. Now it doesn't show anything on the display - no loading screen either.
When I connect the power cable, the LED indicator on the cable block is green, and the HDMI cable seems to be working as the computer recognizes there is a second screen, and operates as if it's in use (my mouse disappears onto it and it shows up as the second screen in my display settings). It even recognizes when I connect and disconnect it, although the power button on the monitor seems to do nothing.
HOWEVER, the LED indicator on the monitor does not light up at all, and the screen is completely black - no loading screen, no nothing, nothing to edit. I have tried disconnecting the power cord and holding down the power button for 60 seconds, no dice. I've tried restarting the computer with the monitor already plugged in. There is also no pinhole reset button that I can find. Is this a lost cause or can I save it?
