Quality and Resolution

Speaking of resolution, 4K UHD will fully deserve to be the winner in the 4K vs Blu ray vs DVD battle. The biggest difference between 4K Ultra HD and traditional Blu-ray is that the former supports resolutions up to 3840 x 2160 (4K), while the latter caps out at 1920 x 1080 (1080p). This significant difference however seems to be surprisingly subtle for human eyes. To sum up, in the quality round of Blu ray vs DVD vs 4K Ultra HD, 4K is four times better than Blu ray, while Bluray is six times higher than DVD.

Movie Storage

The Ultra HD 4K can hold between 66 to 100GB of data, far surpassing HD DVD or Blu ray. But you should know that movies in 4K resolution will take up much more space.


Compare Blu ray and DVD, more resources are available on DVDs as Blu ray is a relatively new technology. The concept of 4K can date back to as early as 2004, but it didn’t come into vogue until 2014.
