Cool Acer Monitor Black Screen Blue Light References. Loose or damaged cables connecting your monitor to the computer can disrupt the transmission of video signals. I cant even turn it on or off on the power button on the front next to the blue led.

So, i tried using the display color calibration settings to change the gamma and color balance of the screen to make it. Web when i turn my acer aspire 7250 laptop on the screen stays black, i tried hooking it up to a monitor and nothing, the blue indicator light comes on and you can hear it trying to start. I cant even turn it on or off on the power button on the front next to the blue led.
