I reset my Windows 10 desktop and my Acer monitor won't work! I turn on my tower and its on, and when I turn my Acer monitor is turned on it shows up with the Acer logo then says "no signal" then goes black and the light in the lower corner lights up. Please help!! (I already turned off then on my tower,
and unplugged my monitor)
