Monoprice Blackbird 4x1 HDMI Quad Multiviewer Switch

This unit works well to show 4 screens at once, as others have stated, the other view modes do not display the video signals well as they are stretched weird. I currently have 4 1080p signals(roku sticks) hooked up to it and it works fine to watch 4 signals at once on my projector. It would be nice if it had optic audio out so i could extract the audio for the soundbar. i had to use a separator audio extractor to do this. same goes for multiple video outputs would be nice as well but i got this to work again with an external hdmi splitter. Overall it works fine but is very basic. but for the money it cant be matched.
