The China-based VR company Pimax has launched a Kickstarter for what they call "8K" and "5K" VR headsets. The cheapest version of the "8K" headset is listed at $500 and the company has more than quadrupled its funding goal. The Pimax 8K has a 3840×2160 resolution per eye for a total resolution of 7680×2160 and 32:9 aspect ratio (an actual 8K resolution would be 7680×4320). The field of view (FOV) for the headset is 200°, and is similar in design to the StarVR headset which has an FOV of 210°. By comparison, the latest HTC Vive and Oculus Rift headsets have a 110° FOV.
While the headsets have a listed refresh rate of 90 Hz, Pimax claims that its "Brainwarp" software technique can effectively double the perceived frame rate:
You may be asking yourself how a VR-ready gaming computer could possibly drive these sorts of graphically demanding resolutions. Pimax's answer is a software technique they call 'Brainwarp', which renders a 4K image only on a single display at time, doing it 150/180 times per second. Pimax says users "perceive a complete 8K at 150/180 Hz with high frame rate," and that it "boosts refresh rate, reduces latency and decreases GPU pressure for Pimax 8K."
Pimax showed off its headset prototypes at CES in January. The company is also developing modular accessories for its headsets.
Just 4.73 times more pixels to reach the "ideal" resolution.

It's k and ki or K and Ki(B?)
It's Kilo versus Kibi, the former have been implied as base 2 since computer began almost, with the latter being a marketing ploy by hard disk manufacturers in order to keep using MB/GB etc while actually giving you 1000/1024's the space you would have previously had under old marketing and technical nomenclature.

Kilo being quite explicit in it's meaning of one thousand (in numbers: 1000) since decimal system began almost. I'll guess you grew up on freedom units?

K is Kelvin (temperature)
k is kilo (1000)
Ki is kibi (1024)
Use the appropriate prefix for the job. The literal meaning of "kilo" is "one thousand". If you mean 1000 use k, and if you mean 1024 use Ki. Simple.

Simple and wrong. The informal definition of kilo meatbags instinctively used before a marketing droid decided to make their hd look bigger was "kilo is base^n where n is the lowest exponent that yields a result nearest to 10^3". Used for decades by scientists and gaming kids, without incidents.
If the international system has been unable to formalize the historical use of kilo and megabyte at the expense of usability, that does not entail the historical use was wrong, it means the international system is full of useless bureaucrats who bent over and made tons of already written documents confusing, only to please a bunch of idiot managers who pushed base 10 measures for data.
Now the damage is difficult to revert, one has to specify k or ki, but try uttering kibi among greybeards.

No, it's not wrong. K (kelvin) and k (kilo) have long been standardised as SI units. Ki (kibi) by the IEC (ISO).
The only problem here is that computing people (k) which has been long establised to mean 1000, and then used it to mean something completely different (1024) which was "convenient" but insane because it ignored established practice in every other field.
All these units *are* standardised. The historical bad practice in computing needs to end, and use the units as standardised.
