At 40m you should use a HD-Base-T system, not a standard cable. A good HDMI cable generally can hit 50-75 feet (15-25m or so). But, you are talking about twice that distance which means you don't just need an equalizer, you need something better. HD-Base-T can handle that distance with no issue at all.
