Since 25 November, if you’ve noticed, YouTube’s video screen is wider than before. This is because now YouTubes video player is optimized for HD video. Since HD is gaining more and more popularity and recognition it is no wonder that YouTube took this step.

Older videos with standartd 4:3 resolutions are shown at their 100% width and  with empty space at both sides.

It is said that not all of the YouTube’s servers are yet updated so there are countries for which YouTube is with the older player.

Of course feedback varies and there are people who do not approve the new  player and want the older one back. There is also an opinion that there should be at least a button available for users which switches between standard and HD screen. Till now, YouTube has not answered to users’ feedbank so we should just wait and see what happens next.
