Does anyone know the difference between a blu ray player and and an up converter dvd player with a hdmi cable?

Question

Yeah you see. Whats the difference in the picture quality between a blu ray player with an hdtv and an up converter dvd player with an hdmi cable connected to a hdtv? i know sorry long question but can someone please answer me Thank you.

Answer 1

Yeah the quality of your video is determined by how much information is displayed. Regular DVD might have 480 lines making up the picture. A BlueRay DVD has 1080 lines making up the picture. When you upconvert a regular DVD, you are basically "stretching" the picture out, but you are not getting any more quality out of it.  The cable you are using is not going to matter, it is the quality of the source that counts.

For instance, if you have two of the same photo on your computer, one is 320*240 and the other is 1024.768, and you take the smaller photo and increase its size with some editing software to make it 1024.768, you know its not going to look as good as the one that was 1024.768 already. Same idea.

Answer 2

The upconverter will scale 480 lines (SD) to either 720p or 1080p. The same function is being done by your HDTV as well (via component or HDMI), so in essence upconverting is not offering much that can't be done by the TV to begin with!

Blu-ray can actually display true 1080p content.  There is usually a big difference between interpolated lines (upconversion) and real lines (1080p).
