4K resolution, also called
4K, refers to a horizontal
resolution in the order of 4,000 pixels and vertical resolution in the order of 2,000 pixels.
[1] Several 4K resolutions exist in the fields of
digital television and
digital cinematography. In the movie projection industry,
Digital Cinema Initiatives (DCI) is the dominant 4K standard. In television and consumer media, 4K
UHD or UHD-1 is the dominant 4K standard. By 2015, 4K television market share had increased greatly as prices fell dramatically during 2014
[2] and 2015. By 2025, more than half of U.S. households are expected to have a 4K-capable TV (2160p), which would be a much faster
adoption rate than that of Full HD (
1080p).

Ok - it seems that this is technology which is actual, and not obsolete, which is always good
So for the domain name 4k-video.com, I would say the price might oscilate somewhere around
price of comparable 3d-video.com ($2,488 USD - but maybe much more, if there will be serious end user who really like or need this domain name). Still "-" in the name brings value down, 4kvideo would be better, but this one is also pretty good. Probability of resale is pretty high, as this is the trend which will be here for next few years. Maybe outbound to relevant end users would help to accelerate the sale.
