    So I got a new Vizio TV! It has 5 hdmi ports and only one of them is labeled 4k@50hz. I looked in the video settings on my Apple TV and it has Auto selected for output, but the footnote states output is currently at 1080p @ 50hz. So is the 50hz hdmi port on the TV the best one to use for the Apple? I've tried to do my homework on hz and different hdmi connections, but it's not sinking it. I have it plugged into that one now and it seems to work great. I have not watched a quality HD movie or anything on it yet though. Thanks for any info.

    I'm guessing all the HDMI in ports are 4k@50hz and they just labelled one. I have not seen any sets that have one HDMI in different than the others, other than a specific port setup for ARC.

    Yes, my TV is labeled differently. Ports 1-4 are labeled 30hz and only port 5 is labeled 50hz. AND, the TV knows the difference too cause when I plugged my direct tv box into port 5 just to see how the picture looked, the tv gave me a pop-up warning that "the broadcast was not in 1080p and that my image may be better in ports 1-4". When I plugged the apple tv into port 5, it did not give me the pop-up. But like I said, I haven't watched anything yet to see if I can notice an actual difference.

    Ah interesting... I have never seen a set like that. I would thing you might notice some lag in fast motion scenes with the 30hz input.

    I don't mean to hijack your thread, but I was wondering what model did you get? Does the tv come on when you use the Siri remote and does it turn off when you put the tv to sleep using the Siri Remote?

    Our newest TV that we bought for our home office has 2 different types of HDMI ports... 2 are 4K@60 and 2 are.... @30.

    A model number for the TV would help. As well as maybe a location. You are saying 50Hz which is usually overseas, but then you mention DirecTV which is mostly USA. USA mostly uses 24, 30, and 60 Hz, while overseas uses 25 and 50Hz.

    The Apple TV does not support 4K, so I'm going to guess you are probably fine with any of your HDMI ports because they all probably support 1080p60. The ports are just labeled that way for 4K material, which can be a PITA figuring out what works with what (which is why I believe Apple skipped out on it for now).

    Some of the Vizio UHD models have four HDMI 1.4 and one HDMI 2.0 port. The main difference is that the HDMI 2.0 port supports higher refresh rates at 4K resolution (50 Hz in Europe, 60 Hz in the US) and (on the Vizio models) doesn't work well with interlaced content (e.g. cable set top boxes).

    For the Apple TV, HDMI 2.0 is irrelevant, so I'd connect it to one of the other ports.
    Yes, that's because of the interlace issue mentioned above. Port 5 is best used for low-latency gaming, if that's something you're interested in.

    Sorry for the delay. TV is a Vizio M60C3 model. It's a US model and I'm in the US, but that port is labeled 50hz. I've had a chance to watch a few movies on iTunes rented through the Apple TV. Can't see a picture difference but the voice/sound doesn't match up with the people mouths on the 50hz hdmi port. Interesting.

    That's unusual. Perhaps a gray import?

    Per the Vizio site
    • HDMI Ports5 (3 down; 2 side)
    • · HDMI Port 1 SpecUHD Video @30Hz, HDCP 2.2 support
    • · HDMI Port 2 SpecUHD Video @30Hz, HDCP 2.2 support
    • · HDMI Port 3 SpecUHD Video @30Hz, HDCP 2.0 support
    • · HDMI Port 4 SpecUHD Video @30Hz, HDCP 2.0 support
    • · HDMI Port 5 SpecUHD Video @60Hz, HDCP 2.2 support
    Any chance of posting a picture of the sticker that lists the model number.

    Yes, the AppleTV should work fine on any of your TV's HDMI ports.

    You may run into issues with that TV if you start getting more 4K sources. For example DirecTV requires 4K@60p for their C61K 4K capable mini client. That means it would have to be hooked up to HDMI 5. If you also had a 4K Blu-Ray player you would have to hook it up to HDMI port 1 or 2, which would limit you to 4K@30Hz. I don't think any commercial 4K Blu-Rays have been released yet that are greater than 30Hz, but they may in the future. For example the Hobbit trilogy could be released at 4K@48Hz I believe.

    I have a Visio series M50. Check your TV's manual page 31 for Adjusting The Audio Settings under Lip Sync. You can tweak it there :)

    The M Series from Vizio is actually one of the better series TVs that Vizio has produced. If I remember correctly, in order of entry-level (read: crappy) to best, Vizio went:

    D Series -> E Series - M Series - P series

    They may have even dropped the P series altogether now, but as of last year, the M series was one of the highest rated TVs Vizio has. I have the M50-C1 which I bought from Costco, and it's been a rock, let alone huge jump from an old LG 32" we used to have, that did 720p at the most.

    Not sure why you are replying to my post. I said nothing about the quality of this model. Just that a 50Hz sticker should not be on the US variant.

    agreed with the sticker. however, saying to hesitate or be anxious with buying a TV from a big box warehouse like Sam's or Costco is a bit of a misnomer, as they do carry good quality TVs there. You just have to know what you are looking for out of the ones they have on display.

    OK...my apologies guys...I took a pic of the port for you guys and lo and behold, it is 60hz!! Yes...I am a dork. Either way, still having the issue with using that port and the speech delay from movies on the Apple TV. I have a direct tv box, but don't know/think it's a 4K any or other, jut their standard he box. It's plugged into port 2. I have my Vizio surround sound plugged into port one due to the ARC capability.

    Does that mean I should leave the Apple TV connected to the 60hz port and try to adjust the sound matching? Does that port offer the best performance?

    Your DirecTV box should have a part number on it. HD receivers will be an H21, H22, H23, HD-DVRs will be HR21, HR22, HR23, HR24, a Genie DVR will be HR34, HR44, HR54, and a mini client would be C31, C41, C51, etc. The only DirecTV device that supports 4K output right now is the C61K mini client. So if you don't have that then it doesn't matter what port it is hooked up to.

    As far as the Apple TV goes I would hook it up to a different port like HDMI 3 and see if you still have the lip-sync issues. There is no reason to have it hooked up to HDMI-5, it should still work as 1080p30 just fine on any of your TV's HDMI ports. If you still have lip-syn issues on the other port then I would recommend you look for the lip sync settings TedGlenview mentioned.

    I haven't tried a whole movie yet, but no voice/lip sync issues watching trailers and other items on Apple TV using port 3! I don't see a video quality difference either.

    So here's one for ya...

    TV is a smart tv obviously, and has Amazon video built in. Last night I watched the same show through Amazon on the tv and then immediately watched it through the Amazon video app on my iPad via AirPlay through the Apple TV. SIGNIFICANT difference in sound quality. Nothing in visual, but audio was significantly better through the Apple TV vice organically on the tv itself.

    Why would that be?

    The built in app is probably lousy by comparison.
