A 4K picture is said to be 20 times better than S.D. and 4 times better than H.D. The test loop playing at the moment seems to justify those claims. To get 4K you need a satellite dish receiver (not cable), a 4K compatible TV, a Foxtel Sports subscription and an IQ4 set top box. I believe it's well worth the outlay.
As this new technology becomes more commonplace, I can only hope some bright spark will eventually outsmart the elusive Yowie (or Bigfoot) and capture a crystal clear 4K image. Or perhaps as the old Go West song goes... "'Im the King of Wishful Thinking".
