Tech Roundup Nov28th

After 3D TV failed to live up to expectations, the big brands have now placed their hopes in ultra high definition 4K sets to supercharge sales.

We put two of the leading 4K TVs through a specially designed lab test to see whether the future of television really is 4K. Read on to discover the results.

Today is also the bumper bargain day that is Black Friday. We'll be updating our site all day long to keep you in the loop on any must have deals. While we also explain your consumer rights when it comes to shopping in the sales.

We've also been putting the iPad mini with Retina display to the test this week, though perhaps not in the way you might think. Find out whether the new mini really is £70 better than the old mini.
