OK, one for the techies here. I posted this under my specific apad model but I guess other models may also be affected so have posted here. I have one problem with my tablet which I hope someone might be able to help with. I stupidly connected the HDMI to my laptop and now any video or utube I try to play only outputs the sound and no video. I get a lttle white triangle in top left corner for a second at the start of the video. Any help would be greatly appreciated. I've tried changing the display settings but to no avail. Everything else on tablet is fine like phots, browser etc... Do you think I've fried my video card or something like that?
