I can't get past the "Surface" Logo when I boot my Surface Pro. When the logo disappears, the screen "flickers" black/grey as it is trying to search for the correct screen resolution or something. The last thing I used the Surface was when I was doing a presentation at work and hooked it up to a projector. Does anyone know if there is a shortcut or boot command (like F8, which doesn't work) to allow me to see the screen to fix this? THANKS... i can't find anything online, and need to fix this asap!
