The Radiient Select-4 is a 4to1 HDMI Switch that has both HDMI and SimplayHD logos, meaning it has passed both HDMI compliance and SimplayHD certification and interoperability testing.
I'm the President of Radiient, and a co-inventor of HDMI, and I just wanted the community to know about our product, as it has solved many problems for our customers who have experienced issues with compatibility when trying to connect multiple HDMI sources to their HDMI displays. Please see our website for details, and search the web for the many positive reviews the product has received.
