Happy New Year although it all seems like a distant memory now! All the more reason after a severally depleted bank balance due to presents and parties to take a look at one of the latest buzz words in media > 4K. Just about every TV manufacturer is quoting "4K" in its latest top models. In this short and informative blog I run through the basics and how you apply resolution to spherical displays...
What is 4K?
4K refers to ultra-high resolution (UHD) displays on the order of 4,000 horizontal pixels. A 4K panel is around 4 times the resolution of 1080p Blu-ray content. Especially for games 4K results in sharper crisper images with more detail. According to industry analyst IHS, 4K display prices are expected to come down dramatically and most major panel vendors will increase production of 4K displays within the next year.

The 4K display standard contains two resolutions:
- 3840*2160: This is the standard resolution supported by TVs and monitors
- 4096*2160: Projectors will support this slightly wider aspect ratio format
How does resolution apply to the spherical surface of the Cobra Curved Display?
What are arc minutes?
It is argued in the industry that once you reach 2 arc mins per optical line pair or below the human eye cannot detect the pixels. This is achievable but not with a single projector on a Cobra Curved Display. When in a few years 8K native panels become available we will pretty much cross that threshold and the benefits of simply increasing the resolution fade away.
