The new technology Ultra HD will replace the currently best TV format Full HD with fourfold resolution in the coming years. First devices – huge televisions and messy beamer – are even already available and have already been tested by the experts of the video. The biggest problem with this TV format, with eight instead of two megapixels, is that there are hardly any image sources that already offer this high resolution. There is a lack of test pictures and test films that can be used to check the advantages of the new technology, or to adjust the picture of the TV monsters perfectly.

The most important three test pictures can be downloaded free of charge and can be tested on the PC or displayed via the photo function of their TV set. So you can see on the full-HD TV how well the down-scaling works and whether brightness and contrast are right.
