I may be a nitpicker, but for me 4k is 4096x2160, or am I wrong? This screen is UHD, or 2160p but not 4k.
____P is no less of a marketing label than 4K, just a different one. Any monitor should be defined by its resolution; however this is clunky as hell- as demonstrated by the sheer mass of people keen to inappropriately use the ____P nomenclature.
UHD seems a valid shorthand of this resolution; and to be fair it tends to get used; although often alongside 4K.
CRTs of course never had meaningful horizontal pixel counts but had very meaningful line numbers so that was what was used in the TV industry.
The broadband situation is sort of similar and has always historically been measured in bits.
With hard drives I don't know if there is a reason they can't put 1000GiB on their "terabyte" hard drives which might be reasonable.
As for hard drives, it's unfortunately not even 1000GiB. It's 1,000,000,000,000 bytes; or 931.32GiB. Of course usually it's actually a bit higher based on the design, and they 'round down'. My OS is reporting my WD Reds as 976GiB, so I'm 'only' missing around 48GiB.
And on that note, I understand the whole 'humans like base 10', but computers like base 2. And now half of my apps use base-10, half use base-2. And I pretty much have to use base-2 for all older stuff, like ROM sizes from old game cartridges.
And I doubt people actually cared about 1000-vs-1024 when they said their file was "three megs", but now instead of consistency we have a mess.
