I was wondering if 1289x544 is HD? Some places advertise it as 720p but I'm not so sure.
 
It is HD, as not every movie is using the 16:9 frame aspect ratio, and 16:9 aspect ratios result in 1280 x 720 pixel or 1920 x 1080 pixel.
A movie with 1280 horizontal and 544 vertical pixels is using 2.35:1 as aspect ratio, which is common for cinematic films.

It is not HD by definition. HD has 16:9 aspect ratio. HD can be 1280x720/60p, 1920x1080/60i, 1920x1080/30p, or 1920x1080/24p.

Does that mean a movie using 1280 or 1920 horizontal pixels, but not 720 or 1080 vertical pixels due to its 2.35:1 aspect ratio is not HD? What about Blu Rays having its content stored in such aspect ratio? Is HD only 1920 x 1080 or 1280 x 720 and nothing else?

The definition of High Definition is fairly strict. Content on Blu-ray that has 2.35:1 aspect ratio does not comply with the definition. Do you care? Will the fact that 2.35:1 aspect ratio is technically not High-Definition make you run to your room, slam the door, fall on your bed, and cry inconsolably?

Yes, it will. I was just curious. I better not tell the 5K VCR that is subpar. Have a good evening anyway.
 
So, it's not HD but it is just as good, right?

This made me laugh.

It still has the same quatlity as bluray, it just has black bars. 720p is seen as hd ready. And so is 1280x544. Technically it is NOT hd, but it is just as sharp and clear etc. It just has black bars because the director decides he likes a wider picture. For instance, a 1920x1080 movie wil fill your entire screen. So will a 1920x940 but witch black bars, this does not mean the quality is any less. Even is you had 2920x2080 still would not matter on any modern age tv.

OK, now I understand. Thanks.

Good even,

1920x1080/60p what forgotten in your statement. I just thought I’d chime in with that because I was researching the same topic as Alpha K.

Hello all. The black bars can be removed by adjusting the picture/resolution settings on your HDTV or UHD TV.
