Connecting HDMI cable to TV crashes laptop

[danv311]

Hi,
When I connect the HDMI cable to the TV, I see nothing on the screen and my laptop starts to blink until it causes an error to the graphics card and sometimes the computer crashes, checked several HDMI cables and that's not the problem. Any suggestions what causes this?
Thanks for the help.

Sounds like a resulution issue, go into controll panel, and make sure under display that you select hdmi only, this will use your tv as main screen, dont split it, most laptops have a shortcut key that when pressed auto switches the screen, this avoids errors and crashes, the main reason for crashes on dual screens i found was the resolution differance, the pc cant decide on which to follow, the crashes(this was way back on old screens). So set laptop resolution to full, make sure it set not to split the screen, but to use the tv as hdmi only. Obviously upgrade your grafix drivers, and see if it helps. Have a look on your laptop for a key that alows screen switching, its usually second function keys on the "F" keys, on my laptop its secondfunction F5, this makes things allot easier.

Hope it helps
