Youtube HQ is a Greasemonkey script that takes that burden away from the user. The script can be configured in two ways: The first mode which is also the default one will always display the video in the highest possible quality on the Youtube website. It will automatically increase the screen size to fit the video on the screen. This makes only sense if the computer is connected to a computer monitor that is capable of displaying the high resolutions.

The second mode of the Greasemonkey script will always load the low quality version of the Youtube video which is excellent for users who are accessing Youtube with a low bandwidth connection or from a system with a small computer monitor.

The benefit of using the Greasemonkey script is obvious. It will automatically resize Youtube videos according to the user’s configuration of the script. Check out out article Youtube Video Download to find out how to download videos from Youtube.
