Why is the size of DVD files so small??

And why does it look good on tvs? I don't understand that.

Small compared to what?

Re: Why is the size of DVD files so small??

To high resolution images, or anything basically,I have several dvds and I put them on the pc and the file player opens them to their actual image size, and it is very small, 5 inches wide at the most, and it has very little definition, yet if you watch them on a tv, even a big tv, it looks fine, and with detail.

Re: Why is the size of DVD files so small??

TVs have DSPs (digital signal processors) in them, for example, which upscale the image quality; mainly so SD content (such as DVD) can look better than it otherwise would on our newer HD TVs.

Also, TVs are FHD 1080p (unless the newest UHD 2160p, of course), whereas computer displays are frequently HIGHER resolution than FHD 1080p TVs -- many are 1440p currently (like Apple's Cinema/Thunderbolt Displays).

Moving picture looks sharper than still images, because our brain processes moving pictures that way, removing motion blur. Is this what you mean?

Re: Why is the size of DVD files so small??

no, when you play a regular dvd on the computer the size of the image is very small. If you blow that size to the size of a tv it would look terrible and pixelated yet on the tv it doesn't look that way but rather well defined.

Re: Why is the size of DVD files so small??

Sounds like you need new DVD player software. Obviously whatever DVD playback program you're using is either absolute crap or is displaying the image in some kind of preview/thumbnail mode.

Re: Why is the size of DVD files so small??

have you played a dvd on the computer?

Re: Why is the size of DVD files so small??

Plenty of times. Looks exactly the same as on a TV if you're using the right software. What program are you playing them on?

Re: Why is the size of DVD files so small??

windows media and media player classic. i'm also talking about non hd dvds.

Re: Why is the size of DVD files so small??

Try downloading Windows DVD Player instead.

Re: Why is the size of DVD files so small??

but those programs open the actual size of the file, tha's my question.

Re: Why is the size of DVD files so small??

The DVD image isn't encoded as some kind of tiny window. DVD might be crap compared to blu ray but it still looks pretty good on my 40" HDTV, let alone a computer monitor. Without knowing the specs of your computer it's impossible to tell but perhaps you need a better graphics card or need to change the screen output resolution?

Re: Why is the size of DVD files so small??

That is my question, why does it look good on the tv but not on the computer? My video and graphics card works fine, the screen is a decent size. When you open the dvd unless you choose full screen it's going to open the file on its actual size and it is very small, it's the size of the movie.

Re: Why is the size of DVD files so small??

Maybe check the settings on your playback software to make sure it matches the screen resolution. It might be set to display everything at original resolution and if it's an HD monitor it won't be upscaling the DVD image to take full advantage of the pixel ratio.

Re: Why is the size of DVD files so small??

no that's just the actual size of the dvd.
