DVD Warranty - what you can do if your DVD does not work correctly

Blu-Ray vs DVD | The difference is clear


The simple fact is, Blu-ray far exceeds DVD in terms of resolution. If you check out our screen capture below, this gives a clear image of just what the difference looks like. Before we get into the specifics, it’s good to understand something;Blu-ray and a well-mastered DVD can look very similar if you’re sitting far enough away from the screen. There is a point at which our eyes lose the ability to render additional detail. The truth is, though, most of us sit pretty close—or our TVs are big enough for us to notice the difference.

1080p resolution (also called high definition) is what is possible on the Blu-ray Disc format, compared with DVD’s 576i resolution. To break it down further, you get 1920×1080 pixels on a Blu-ray—that’s 2,073,600 pixels, whereas DVD only delivers just 414,720 pixels. That means Blu-ray is exactly 5x the resolution of DVD. Imagine watching just a 1/5 rectangle on your big screen TV and then stretching that across the rest of the surface area; that’s what you’re essentially doing every time you watch a DVD.


DVD Players – Blu-ray discs cannot and will not play in a standard DVD player, because the red laser used in DVD players is too large to read the tiny grooves in a Blu-ray disc.

Blu-ray Players – All Blu-ray players currently on the market (including the Playstation 3+4) are backwards compatible and will still play standard DVDs. However, the DVD image displayed, while still decent, will not be high definition quality like a Blu-ray disc.
