The best solution for "older" TV equipment

My boys have a new Wii U get paid. The joy was of course huge. But then the disappointment: the already older TV does not have a matching connector for the supplied cable. So off to the next big retailer. There I received the sobering information that there is allegedly no halfway-effective solution to connect the Wii U with the TV device. The good advice, but a newer model, so to buy a flat screen TV, I declined with thanks.
But thanks be to Amazon! Here you can really find everything. And thanks to the many reviews and comments, I then ordered this cable. The Wii U and TV connected to cable and ...... there is the TV unit no picture !!!!
At this point I should like to thank you for the comment by Mr Thorsten Schachzig, who pointed out that you have to choose in the settings "No HDMI". And now all the kids and I are happy and able to play at last.
So a strong buy recommendation!
