Question

Blu-ray provide how many more time the resolution of dvd movies????

Answer 1

Careful - "Resolution" has a very specific meaning.  The actual picture quality improvement is larger than than the 6 times increased resolution.

If you set your computer monitor to 600x480 it has the exact same 'resolution' as your standard def TV.  But the computer monitor is still a lot sharper and clearer.  

(Lots of reasons - dot pitch, refresh rate, progressive instead of interlace, color depth, etc.)

The numbers would say there is a 6 fold increase in 'resolution', but I would opinion that the picture quality improvement is more like 20 times over standard DVD.

Answer 2

Ads say 6X ... but that is only total pixels and is not a legitimate measure of relative resolution.

Normally one would use line pairs for CRTs, but for a flatscreen display the usual measure of resolution is vertical pixels. So Blu-ray @ 1080 pixels vs DVD at 480 (NTSC) or 576 (PAL) is 2.25x (NTSC) or 1.875x (PAL) the vertical resolution (or 1920 / 720 = 2.67x the horizontal resolution).

Answer 3

You  would see an increase of 225% MORE resolution on 1080 than 480.....

Or 600 more lines of detail....

Answer 4

its a very noticeable improvement over a reg. dvd - i have read about 5x -  but not all blu ray dvds are made equal - some titles will show alot better than some others - but all will be better than a reg. dvd -  and keep in mind - even blu ray movies are compressed from the original film -   for example - when they film a movie - its in 35 mm - and if you wanted to transfer the whole 35 mm file just the way it was shot -- it would not fit on a blu ray disc -  it still needs to be compressed -   - they are working on a TV that will be 4 times the resolution of 1080p of today --  when and if that ever comes in production - it would make 1080p of today look as bad as 480i lines of previous tv before 1080p

blu ray players have come down alot in price - and they do a pretty good job with reg. dvds also -  once you get used to blu ray - 1080p etc. Flat TVs etc. --  you wont want to look back -
