YouTube: Switch to HD When Playing YouTube Videos in Full Screen

YouTube added a clever option for those who want to see a better video quality in full screen. If a video is available in a HD format, you can view it in HD when switching to the full screen mode.

Just click on the drop-down menu for switching between formats, click on “Settings” and enable “Always play HD when switching to fullscreen (when available)”. You can also change playback quality settings from this page.

Unfortunately, when you exit the full screen mode, YouTube doesn’t switch to the previous format. As YouTube’s help center explains, “if you play HD video in a small player, the computer works overtime to scale down the video to fit within the player, which may result in choppy playback. It’s always best to play the video size that best fits the size of the video player.”
