I picked up two old 23 inch Cinema Displays at a garage sale, seller said they definitely work. I brought them, home, plugged in the displays to the power bricks and power bricks into the wall, pressed power button the side, and I see nothing on either display. I don't have anything sending a video signal to them, but they should at least show something on the screen, right? What should I try next?

Thanks
