Bluray resolution vs my 1024 x 576 native projector?

Question

I have a movie projector with 1024x576 native resolution. I play DVD's with it. Regular TV seems to grainy so I don't do it. Would Blu Ray player make any difference? Is the projector's resolution high enough to make a distinction between DVD and BluRay or would I have to replace my projecor with a higher resolution TV or another projector to get some benefits from a bluray upgrade? And what is a native 1024x576 anyways? what is native about it?

Answer 1

As it stands... DVD's only output at 720x576 at a maximum in terms of pixel resolution. US which primarily uses NTSC DVDs output frames of 720x480 at 60hz which achieves about 29fps. EU PAL DVDs achieve the higher resolution of 720x576 but subsequently only at 50hz or about 23fps due to data constraints on SCART/Composite/Component. A Blu-Ray disk will offer a resolution of 1920x1080 at 100hz which is just shy of 60fps. Plus, blu-ray supports progressive scan where each image is built up from first to last pixel as opposed to interlacing used in DVD whereby the even lines are built up in one cycle followed by the odd lines (or vice versa i dont remember which)



1st, a Blu-Ray player, on paper, would make a difference, though it would only be a negligable difference. Its called a native 1024x576 since that is the resolution it is designed for. It will be able to handle lower resolutions for the visually impaired but a resolution of 640x480 would not be 'native'. Since a US DVD only outputs at 720x480 then you would be able to get more out the projector from a blu-ray source. But it would be wasted in that a blu ray will do 1920x1080.



If you choose to upgrade to blue ray you need to invest in the source (blu ray player, PS3, etc), the output (HDTV, HD projector - not sure if or where you can get them), and the connectivity (HDMI cable). If you get a good source and output, dont be tempted by a cheaper cable. Insufficient connectivity will destroy the benefits of blu ray. Invest in a cable that can carry the 4.95 Gbps that blu ray requires, such as a 750 series monster cable :)

Answer 2

DVDs are 720 x 480 (480p) resolution. BluRays are 1920x1080 (1080p). Your projector is 1024x576 (576p).



Native resolution describes the resolution of your projector. Video sources that are the same resolution as your native will look the best on the projector. The larger the descrepancy between the source and projector resolution, the worst the image will look because the projector has to resize or scale the video signal to fit the projector resolution.



Bottom line, a standard DVD will look better on your projector than a BluRay DVD because 480p DVD is closer to 576p, than a 1080p BluRay. If you want to enjoy BluRays, get a true HD projector (720p or 1080p).

Answer 3

No no no...that does not compute! Resolution has nothing to do with it. The resolution you are talking about is width by height. You can have a display that is 1024x768 that is <720p, 720p, or 1080p. I have to be honest, I am baffled by what you are describing with this "down-scaling" and what that really means. Are you talking about the black bands above and below the picture? If so, that is more of an issue with the fact that most things (even brand spankin new LCD/LED televisions) don't utilize precise 16:9 aspect ratios. For example, I have a Samsung 6 series widescreen LCD TV that still has the banding on 16:9 movies. I know its a pain in the rear, but can you describe the issue you are having in more detail?

Answer 4

the higher the native resoution, the closer the tv is to true hd



your projector is not hd



so even if you hook up bluray via component cable you will not see hd but bluray will look a little better than regular dvd on your projector
