Hi, I'm very bad with technology so this could be something very simple. But when I turn my monitor on it show the acer logo and then the energy star screen but then just shows a screen of nothing. The only button that works on the monitor is the "on" button and it definitely isnt the playstation or the hdmi as I have used it on a tv and it works. I have also connected my laptop using the VGA?(the blue wire with screws on it) and that didnt work.its an acer k222hql if the helps. Any help would be appreciated. Thanks
