Why not to stream YouTube videos in HD
There are several reasons streaming HD quality videos on YouTube may not make sense. For instance, if you have a limited Internet plan, watching HD videos can siphon the bandwidth. HD videos — especially 720P, 1080P and other high quality videos — will not buffer faster unless you have a really good Internet speed.
Even monitors and smartphones with smaller resolutions should stay away from YouTube HD videos, as the difference — both in audio and video quality — while playing videos is hardly noticeable.
Videos on YouTube doesn’t work on HD sometimes, and if that’s the case with you, it’s time to switch to a lower resolution.
