Here’s a primer about DVDupscalingand how the results compare to Blu-ray.
When you put a disc into a DVD player, the player reads this resolution.
Hence, DVD is classified as a standard resolution format.

This process is calledprogressive scan.
Progressive scan DVD players output the same resolution as other players but provide a smoother-looking image.
In response, DVD makers created a process called upscaling.
However, upscaling can’t convert standard DVD images into true high-definition (or 4K) images.
Upscaling works best with fixed pixel displays, such asplasma,LCD, andOLEDTVs.
Do I Need an Upscaling DVD Player?
you’re able to hook up any DVD player to an HDTV.
Upscaling DVD players are better able to match the natural pixel resolution of an HDTV.
Most newer TVs don’t have S-video inputs.
If your DVD player is progressive-scan capable, always use this option when connected to a progressive-scan capable TV.
True High-Definition Viewing
DVD upscaling is only an approximation of the high-definition viewing experience.
The Blu-ray Disc format supports 720p, 1080i, and 1080p resolutions.
Compared to Blu-ray Disc, an upscaled DVD tends to look flatter and softer, especially in the background.
There’s a difference when looking at reds and blues.
With upscaled DVDs, reds and blues tend to override underlying detail.
The same colors in Blu-ray are tight, with the detail visible under the color.
Some Blu-ray Disc players have built-in 4K upscaling for both DVD and Blu-ray Disc playback.
