Epiphan AV.io 4K Review @ Vortez
 

We’ve been using the Epiphan AV.io 4K for over two months now and cannot praise it enough. Prior to this we were using the Razer Ripsaw which was another great capture device but sadly, lacked the 4K support. There are very few 4K capture solutions on the market at the consumer level and the AV.io 4K can quite easily therefore monopolize in this field.
