Despite a fairly constant battle with ISPs, Netflix has unleashed its Super HD video quality to all streaming customers, regardless of the service provider. Previously, Super HD was only available to customers whose ISP had implemented Open Connect delivery system, but member requests have encouraged them to roll it out to all members.
What is Open Connect? It is a platform in which an ISP can have a direct, open connection directly to Netflix. Instead of having to connect through the vast pipelines of the Internet, the direct connection allows for a much better picture quality.
So, without Open Connect, how likely is it that a person will receive Super HD? According to Netflix,
The ability to receive Super HD depends on broadband quality and performance. Netflix members who subscribe to an ISP with a direct Netflix connection will get the best experience.
Of course Netflix is still trying to sell ISPs on Open Connect, which is completely free to ISPs, but they do believe that standard connections will be capable of Super HD. Super HD, which is a higher quality, less compressed video quality, is only available on certain titles and can only be streamed to certain devices.
