I have a Dell Inspiron Laptop and a Samsung TV. Literally today, my HDMI cord was connected to my laptop and everything was working just fine. I had the display on EXTEND. As my boyfriend decided to use my computer, he thought that the computer wasn't working (but it was, he just had to turn on my TV) so then he decides to press the power button. When we turned it back on my computer was working just fine but the connection of the HDMI cord from the TV to the computer didn't work anymore. I bought a newer cord and it still isn't working.
What can I possibly do to fix this? Is it never going to connect with an HDMI now?
