Retina YouTube has been deprecated!

YouTube now automatically chooses 720p video if your display has a pixel density of 2 - both in the Flash and HTML5 players.

This has rendered the extension useless - which is a good thing. I'm glad YouTube finally implemented this properly.

Thanks for the support!

(If you still wish to download the extension, it is available here:)

Retina YouTube makes videos sparkle on your Retina Display!

Retina YouTube is a browser extension for Safari and Google Chrome that automatically switches the resolution of YouTube videos to 720p (or 1080p if desired).

Works in both the YouTube HTML5 player (join at http://youtube.com/html5) and the YouTube flash player. (HTML5 recommended).

The problem and the solution

On a Retina display, OS X no longer deals in actual pixels, but in logical pixels. As a result of this, when YouTube presents a video on their webpage it is 360 logical pixels tall (resulting in YouTube sending a 360p video to the player). But on a Retina Display, where pixels are in a 2:1 ratio, a 720p video scales perfectly to this 360-pixel-tall-area.

When you choose a 720p video in YouTube's player, it scales perfectly. But manually selecting 720p for every video can get tiring.

This is why I created Retina Youtube, which does the switching for you!
