This is the Certificate of Conformacy for the 60W power supply provided with Sonnet's SF3 Series Card Readers, and the Thunderbolt 2 and 3 Editions of the Echo Express SEL, Echo Express SE-I, and Twin 10G.
For video up to and including 1080p (1920x1080), Sonnet recommends either the "Moshi Mini DP to HDMI Adapter with Audio Support" or the "Griffin Mini DisplayPort to HDMI with Audio + DVI". Many other adapters are poorly designed and have issues with proper color space.
For video up to and including 4k (3840x2160) which is supported by Thunderbolt 2, Sonnet recommends the Accell B086B-005B-2 Ultra Display Port 1.1 to HDMI 1.4 Adapter.
