The largest 4K LED videowall in the world has been installed at Churchill Downs, the home of the world famous Kentucky Derby horse race.

The new wall was opened just in time for the Spring Meet 2014, which took place over the weekend at the US venue.

The $12 million (£7.1 million) videowall, which was been dubbed 'the Big Board', measures in at 171 feet tall by 90 feet wide, and was built by Panasonic Enterprise Solutions Company.

It is positioned halfway down the finishing straight of the race course, meaning that those in the clubhouse, grandstand are able to view it, as well as the infield spectators.

Churchill Downs president Kevin Flanery told InAVate: "One of the complaints people would always make was that they went to the Derby and never saw a horse."

The videowall has a resolution of 2,160 x 4,000 pixels and weighs in at 1.2 million pounds. It is capable of displaying over nine million lines of resolution, allowing operators to display relays, image close-ups, race results and betting odds.

The new videowall is also able to display advertising, multiple split-screen views and recorded programming, Mr Flanery confirmed.
