google chromecast $30, amazon fire stick $40, roku $50. Depending on what kind of phone or tablet you have some solutions make it easier than others.=QUOTE]
Those are apps which deliver content, but not whatever is on your tablet. My HDTV already has Netflix, Hulu, etc, etc, so those I don't need to project.
no, you can cast anything on your tablet or phone to that device and watch what is on it without having to plug it in to the TV. If I am watching a youtube video on my phone or tablet I hit the cast button and bam, its on my tv from my couch.
they also have app viewing and etc but they do have casting similar to what you are doing but without the wires.
prior to this technology I was doing what you are doing.
(I rarely do any of it anyway)
