We do not even have much content for 4K TVs and now
Sharp has announced an 8K, 85 inch LV-85001 for just US $133,000.
In fact broadcast testing of 8K is not scheduled to begin until
2016.
8K is 7680 x 4320, which is 104 pixels per inch at the 85-inch
size; the contrast ratio is 100,000:1 with viewing angles of 176
degrees. It will be available October 31, 2015.
When I first got into the technology business, hardware was always
lagging behind need. Seems during the past ten years technology is
leading, and searching for content and relevance before its
typically ultra-short life cycle ends. Thank goodness for early
adopters, who take the arrows and pay the big bucks so we can
enjoy later.
