Why do i have sound and a green screen on my laptop when watching netflix

This has nothing to do with Netflix, you would get the same result with any DVD regardless of its origin. Chances are that is the laptop trying to revert to a screen saver or power save mode during the movie.

Check your laptop's power and screen saver settings. If you are experiencing the problem every 3 minutes or so, your screen saver is most likely scheduled to go on after 3 minutes of inactivity. The same goes for your monitor-- it may try to dim or turn off after a certain amount of time.

To change these settings to a longer delay, go to your desktop and right click. Select "Properties". Choose the "screen saver" tab, and change the "wait:" field to a higher number. Or, just turn the screen saver off by selecting "(none)" under the screen saver dropbox. You may also click "Power" and change the time for "turn off monitor" to "never", or a longer amount of time.

Your processor is not powerful enough or your internet connection is weak. I'd bet processor. This usually occurs with tablets or older PC's.
