What TV output do you mean? It has wireless screen mirroring. I have a bluray player with miracast and I mirror my phone to my TV with a simple tap. Or you can do it wired with a mhl adapter. Its micro USB to HDMI. But get the right one for the s3. (11 pin) you can get them on amazon for anywhere between 10 and 50 dollars depending on quality.

 

Its HDMI now. Not sure about rca adapter (yellow red white) it does high def now.

 

Wow! That's really nice. How would I mirror my S3 to my Samsung Tv. I have chromecastt but that only sends specifice progrqms to the tV. Mirroring would be much more useful.

My blu ray player has miracast built in. I looked for the feature when I bought it. And the s3 has it as well, in pull down quick settings "screen mirroring". But if your blu ray player doesn't have it, you can get a miracast dongle on amazon for between 15 to 50 dollars. It looks kinda like a chromecast, but for devices (like s3) that have miracast, it mirrors your screen completely. I use it on my s3 and my nexus 7(2013).

 

Yes that'll work fine, you don't need miracas to use an HDMI adaptor. I do it all the time. Make sure you buy an HDMI adaptor that has a mini USB input. As the phone will need to be playing the video and it really drains the battery without it being on charge. The official Samsung one does for sure.

 

If you want to do it with wires, you just need an mhl adapter, or the Samsung adapter. Miracast is for doing it wirelessly. With miracast I just sit on my couch and tap screen mirroring. I used to do it with mhl until I found the joys wireless miracast.

 

That's a good question. Theoretically it should. All the pieces fit, but its hard to say until you try.

 

One thing you need to keep in mind when mirroring with cables. It can cause excess wear and tear on the port if the phone is moved a lot. If you plan on playing games or handling your phone while mirroring then wireless is definitely the way to go. The S3 ports are known to be delicate. I've read quite a few threads where members are asking for help replacing their ports.

 

Yeah. My phone is about eleven months old and my port has so much play in it when I'm charging it. Zero connection issues so far, but I'm sure it's in the future for this phone.
