Yeah I agree 2160P should have been the consumer name.  Who knows what those marketing departments will come up with next.

Didn't like the name before but it started to make sense to me.

4K means 4 x the pixels of 1080p, hence it's 4x 1080 = 4k that's how I explain it tomyself.

He in correct in that it is 4 x 1080p.

But you need to think of it as

( ) = 1920 x 1080 picture.

So '4x' is therefore a better name. Or XXXX if you are Australian.

Why is naming the standard by its horizontal resolution better than using the verticalresolution?

This is simply a case of aligning standards which is something very sorely needed in the video production/broadcast industry.


EDIT: I accidentally a word.

One of these is meant to be a 'vertical' I'm sure.

Only for consistency.

Are you going to change you name to 4k? :D

Consistency with what? Look at the history of consumer video. What did we label DVD? 480p? 576p? What about VHS? What about Betamax?

Blu-ray & HDTV related hardware are the first times pixel resolution has been used by consumers and this was on the back of a horribly messy set of standards that I like to refer to as the 'Dark Ages'.

The vertical resolution is arguably more confusing to the consumer than changing now to 2k/4k/8k. How many 1080p films actually have 1080 pixels of image? The 16:9 ones do normally but anything with a different aspect ratio is now 1920x800 or something else.

Show two films on a 1080p panel side by side to a consumer and the majority of them will say the 2.35:1 is of a 'lesser quality' regardless of what you explain to them because they see 'black bars' on the panel. This is made even worse after spending time explaining vertical resolution to them.

A 4k panel is so much easier to explain. Your image fits in this rectangle, the different numbers are different resolutions (quality) which are measured horizontally.

I think bringing consumer devices and industry standards together will improve consumer expectations of content from these industries as well.

First we change the age-old definition of "marriage" to mean something completely different.  Now we want to change "4k resolution", which we've had for nearly 2 decades, long before upstart 2160p was thought of, or even 1080p for that matter.  What could be simpler than 4k = 4k pixels wide more or less.  Just because 2160p fits into 4k resolution doesn't mean we can no longer call it 4k.  I say let it be!

I think 4K is a better name than 2160p because it is easier to remember.

Also continuing to call formats "Full HD" "Ultra HD" etc will not turn out well in the end. In the future when we have even higher resolution displays people will struggle to remember exactly what "Full HD" was, whereas it will be easy to remember the quality when it is called 4K.

Although technically  4K is "Ultra HD," it seems to me that 4K is like HD, whereas 8K is like Full HD.

I don't mind it as long as they don't change back to the 720p/1080p descriptions.

http://en.wikipedia.org/wiki/4K_resolution

in summary there is no single 4K definition - we may need to rethink this argument!

4K Ultra high definition television 3840 × 2160 (8,294,400)
Digital Cinema Initiatives 4k (native resolution) 4096 × 2160 (8,847,360 )
DCI 4K (CinemaScope cropped) 4096 × 1714 (7,020,544 )
DCI 4K (flat cropped) 3996 × 2160 (8,631,360 )
Academy 4K (storage format) 3656 × 2664  (9,739,584 )
Full aperture 4K (storage format) 4096 × 3112 (12,746,752)


2K resolution should be 2048 x 1080 - but most TVs are 1920 x 1080 - someone stole 128 pixels!!!

Are we confused yet?

I guess this is technically the next step up from 1920x1080 (for TV anyway)
