If Blu-ray players upscale DVDs to 1080p HD display then wouldnt it be pointless to buy Blu-ray movies??

Question

Blu-ray players make your old DVDs to a full 1080p HD display... so this must mean that buying Blu-ray movies would be pointless... right??

DVDs are cheaper than Blu-ray movies and they both look the same in a Blu-ray player if you have a 1080p TV... am I right or wong?

Answer 1

Take a 720x480 (about 350k pixel ) JPEG  and scale it up to 1920x1080

Now take a 1920x1080 (about 2 mpixel JPEG). Which one do you think will be sharper and have more detail?

Scaling up fits the screen, but it can only estimate the interpolated pixels.

Answer 2

Not really.

While DVDs can be scaled to fit the HD screen and the picture has 1920 x 1080 pixels and is drawn progressively (i.e. 1080p) the DETAIL in the image can't match that of the the same picture recorded in 1080p.

The basic problem is you can't put in detail that isn't in the original lower resolution image. See the article at the link for further explanation.

Answer 3

Blu-ray DIsks are mastered in 1080p, while all DVD's created are recorded in 480i.  No matter what Up-scaler you get, DVD content is 480i, so it will not have the detail as a Blu-ray Disk.  

I always say to folks Garbage in, Garbage out.  You can't polish a t**d!
