Hello,

I recently connected my laptop to my tv via hdmi (both the tv and computer were displaying everything fine). I closed the computer without disconnecting the hdmi. Next time I opened my computer, the display on the tv still appears but nothing on the computer screen. If I disconnect the hdmi, all I get is sound on the computer, still nothing on the display though. I tried changing display settings, but I never changed anything on it previously so I don't know what could have changed. Please help.
