I've always used my HDMI cable to hook up an extended display of my laptop on my TV. Lately it will often not work. I typically end up figiting with it, unplugging and plugging back in the hdmi cable, turning the tv off then back on, closing my laptop and reopening it, etc... Eventually, it comes back on and stays on. I don't know why it's ever off in the first place. When it is off, my laptop doesn't recognize or detect that it is plugged in How do I fix this problem?
