External Monitor Issues

I'm hoping this problem is a product of my own stupidity and not anything serious. I updated my display driver today (Intel(R) HD Graphics (Core i5)), and afterwards when I plugged my tv into my computer via HDMI cable both screens remained blank and my tv said that no signal was found. My laptop screen remained blank even after removing the HDMI cable and become unresponsive (like it just went to sleep randomly). In order to get the screen to turn on again I had to turn my computer off and back on. I know there isn't a problem with my tv because literally just before I downloaded the display driver I was using it as an extended display.I made sure to download the 64 bit Windows 7 driver,and I know my HDMI cable was plugged into the correct input on the tv. I'm assuming the driver is the source of my problem, but I don't know how to go about fixing the problem. If anyone has any suggestions or solutions I would greatly appreciate it!

    Try this, turn on your computer on without the TV hook-up, and change the display settings to default then shut it down. Now, connected the TV to any HDMI equipment you have except your computer, if you don’t have anything else. Turn the TV on and select between the inputs to reset the default video inputs and turn TV off. Turn computer on and when computer is fully started connect TV to computer. Turn TV on then go to Display Panel and change the settings.

    Hope that’s all there is to it.
  2. Nevermind I got it figured out. The driver I downloaded didn't have external monitor capability. Doesn't really make sense. I had to end up going to and downloading my driver from there as opposed to
