Connect your Netflix-enabled device to your HDTV via either a component or HDMI cable. If you are watching on your computer, make sure your monitor’s resolution is at least 1280x720.
Open the Netflix application on your Netflix-enabled device or navigate to the Netflix homepage on your computer and log in to your Netflix account.
Click the “Genres” button at the top of the page and select “HD.” You will then find a list of all of the movies that you are able to stream in high definition. Browse through the list and add movies to your Instant Queue or watch them instantly.
