A:AnswerI don't know. This remote works on an infra red (IR) signal. If the U VERSE remote is an IR signal, the answer is yes. If the U VERSE remote is a radio signal (RF), the answer is no.
A:AnswerYes the harmony is compatible with the most current U Verse controllers. The bigger issue is that the specific model of TV receiver, your TV and audio amp/receiver are in the harmony database. With over 200,000 devices available in the database it is highly probable yours are there. You can check to make sure by using the programming application to make sure each of your devices is listed in the harmony database.
A:AnswerMute button is lower left of middle third. The center of gravity is around lower third, leaving the mute around middle CoG. (Hopefully, that makes sense because I'm trying to be more descriptive, and might come up short.)

Enter manufacturer and model# to see if controllable. Considering has compatibility will over 100,000 devices, odds are you should be good.
A:AnswerIf the projector has a infra red remote you should be able to enter the model number to set up. If not you will need the original IR remote and can manually program any button it will take a bit longer but you can customize it however. Again only if device has IR remote.
A:AnswerI read the material...it said no and also during the setup it also stated it would not work. However...I set it up last night and I set up an identity for the Fire TV anyway as the instructions said it could help for some other reason that I now forget. I was really surprised to find that on my TV it worked when I chose the correct HDMI slot from the remote. The back button did not match the one on the remote...but it had a screen option to perform this function. I think that I can go back and re-associate the correct button with that function. The navigation buttons and select buttons worked perfectly. I have an LG OLED if that makes any difference...I don't know. So...I could not guarantee the same results on any other TV. I would guess that the chances are good though. Good Luck.
