I connected my Samsung TV to the WiFi for the first time two weeks ago because I wanted to play with the multi-screen-view thing, and it didn't appear to work with two HDMI cables.

It has not shut up asking me to update the fucking thing. Every time I turn the TV on, about twenty seconds later an update prompt will pop up, and it will not go away until I actively dismiss it. This happened even after disconnecting and forgetting the wifi. Never again.
