If you happened to check out our hands-on with the Sprint HTC Evo 3D you would have heard mention of the microUSB to HDMI output that allows for photo, video and audio output. If you're lucky enough to have an MHL enabled TV it should also charge while displaying whatever it is you want it to. Oddly enough, that information was left off of the official announcement but is really one of the finer additions to the Sprint HTC Evo 3D.
While it is awesome to see the port finally being mentioned it is only to fair to note that this really isn't the first time it has come up on devices. Initially, it was mentioned to of have been enabled on U.S. released Samsung Galaxy S devices such as T-Mobile’s Samsung Vibrant and AT&T’s Samsung Captivate but it needed Froyo in order to work. Samsung later confirmed this as not being accurate despite them having made available the microUSB to HDMI cables on the Samsung site, which were quickly removed.
Although the history of the port seems a little confusing, one thing for certain is that its appearance on the Sprint HTC Evo 3D signals that it is now ready for market use. Hopefully, this time around we'll start to see a lot more devices making use of it. We'd be remiss if we neglected to note that Samsung once again has their name in the mix here as well. The Samsung Galaxy S II is also noted to be MHL enabled, something that went rather unnoticed across most media outlets.
