HEY BHAGWAN! So, now you got it... FINALLY! Thanks!
So conclusion learnt is that, if the video aspect ratio = monitor aspect ratio, then there are no mattes (black stripes). And when ratio of video > monitor aspect ratio, then there ARE mattes.

Seriously dude.. you should have observed that way before! ....

 

[Zangetsu]

Btw where to check current monitor setup is 16:9 or not?

 

[Vyom]

Look for the term used as, "Native Resolution". It's always mentioned along with the documentation of any monitor.
Native resolution is the resolution which the monitor support by default or you can say, that on which the monitor would work perfectly well.
Now, divide this ratio, and you should get a fraction, which would further yield only decimal result. Like 4:3, 16:9.. etc... etc...

Like vineet said its decided by your native resolution. Say if your native resolution is 1440*900 then its 16:10, If its 1920*1080 then its 16:9, if 1920*1200 then its 16:10.

One can scale a video to 1080 resolution high, but it doesn't make it 1080p, i.e. the video isn't originally of a resolution of 1920x1080 with 1080 horizontal lines of vertical resolution but can be progressively scanned.

Exactly. And the one who are progressively scanned have a different name i.e 1080i while those who natively have this resolution are called 1080p. Actually advertisers earn a lot because of this confusion as many customers don't know the exact difference between these.

Wooah....! You guys are really really confused. Instead of writing it up, guiding the bunch to two informative links.

1080i vs p
HDTV: 1080i Vs. 1080p? What’s the difference?

Progressive scane is not 1080i.

That's not what I meant, 1080i = 1080 horizontal lines interlaced
1080p = 1080 horizontal lines Progressively scanned

Did anybody viewed/checked any original BD Movie from Disc in Plasma/HDTV?Did u see those black strips or not?coz I havent seen amy original BD Movie in Blu-Ray Player...

Oh yeah got confused with that. Got it now. I remember one thing always. 1080i=bad and 1080p=good. Got confused with the technical terms.

Yes there are black strips.

 

[skeletor]

It might be the case that video itself has those two black stripes.

Yeah it happens many time. I downloaded a video (DAO Sacred Ashed Trailer) and no matter what I do but the black bands were there and I would stretch it then video looks broken so I thought that video has black bands and nothing can be done so I watch that with those bands.

Guys,
I had a Dual Audio mkv(eng + chinese) with a bitrate of 16.9Mbps
& I use mkvmerge to remove the chinese audio so the new mkv media properties are all same as previous but only one difference bitrate is reduced to 15.4Mbps.So Is there any loss in video quality?

 

[sygeek]

^Nope.....

When you removed that audio then the overall bitrate got reduced but the quality of video and the other audio is still the same.

Ok..so u mean
overall bitrate = video bitrate + audio bitrate

 

[gameranand]

Yup. Thats right.

Usually people make the mistake of thinking that for Full HD , the video has to be 1920x1080 , Resolutions like 1920x800 aare not Full HD. This is a misconception, Films are made in such a way that only after adding the black bars will the total resolution be 1920x1080. One exception is AVATAR , which is available at 1920x1080. Other HD Movies are all like 1920x800 .

^^ Its a little hard to believe what you have said!
Have you read that somewhere, or your own observation?
