4K is the next step up from 1080p, offering 3,840x2,160 pixels of televisual entertainment. Having twice the vertical resolution should mean it's twice as sharp, but beyond a certain point it's very hard to tell the difference. As Geoffrey Morrison points out on our sister site CNET.com, you'll need a much bigger TV than 55 inches to enjoy the full benefit of 4K. A much more important upgrade would be to how many frames per second you're seeing. This is what Peter Jackson did with The Hobbit -- its 48 frames per second created an eerily realistic effect that I didn't feel worked particularly well with his fantastical subject matter, but nevertheless was very impressive.

Previous tests have had similar results, suggesting that earlier estimates overstated the potential problem, Campaigners worried as many as 2 million homes would be affected, while telecoms watchdog Ofcom estimated that as many as 900,000 homes could have problems with 4G and Freeview, When phone networks launch 4G services this summer, they'll use the whale iphone case the 800MHz band, which is the same as Freeview -- leading to concerns that your TV would suffer interference, Fortunately it's easily fixed with a special filter that's attached to your TV aerial, paid for by the phone networks..
The mobile networks have stumped up £180m to spend on fitting filters for affected homes. But the networks will get that money back if the problem turns out not to be a problem at all.

Only the airwaves auctioned off to the other networks are at risk, but we won't see 4G services from those networks until later in the year. What do you think of 4G?
