    [This review was collected as part of a promotion.] I was very impressed by this Vizio smart tv in 4K! I honestly could not believe it was a Vizio; it is so superior you would never guess it wasn’t a higher end name brand! I have another higher end brand 4k smart tv and I actually prefer my new vizio! I love that the Vizio tv has a free tv option to watch older episodes of certain cable shows. I love the superior screen display. It is so crystal clear! I will never underestimate a Vizio again! I am now a new vizio customer! I will be recommending the brand and this tv to anyone I know that is looking for a new reliable TV!!

    Nice tv!

    I bought the P Series Quantum X 75” a month ago. The TV is very stable. The blacks produced by this TV are absolutely perfect. The contrast ratio is one of the best due to the incredible brightness. It works as expected. This is my first Vizio TV and I am very happy with this purchase.

  4. Jazyj

    This TV has the Perfect picture and is extremely Bright.
    We live over the water with windows pointing into the morning sun and this TV is bright enough to see all the details on sunny days. With the “auto” ambient lighting the brightness of the screen changes intensity at night so the screen is never too bright while watching movies at night.

    I finally got my new 65 inch P-Series Quantum X TV mounted on my wall. It is a sight to behold. My Vizio remote actually runs my FireTV Cube. The HDMI port automatically named itself FireTV Cube! The sound is just okay. It is loud but not as full as my old sound bar. I plan to buy a Vizio sound bar to complete the experience. I rated it four star for the sound (it is clean just lacking bottom, base thump). I did notice when the screen suddenly goes black and there is a bright light within, there is a two second creep in effect. This doesn’t bother me. I have not seen any motion blur. That would be a big deal. I love this American product. It is by far, the best TV I have ever owned.

    Purchased 23 months ago. Slowly had reboot issues until it did not work at all. Back panel was heat warped 1/4 inch…replaced as safety item. Cheap components–hope this one lasts longer.

  7. MurphKXF127

    Bought it about 8 months ago and only if the picture is set on Game, seems like the power supply gets to hot and will shut off on its own and will not turn on until it cools off. Also another issue I have is out of nowhere, I get “No Network Connection”. When I go to system info, it says the wifi signal strength is 100 but will not work. I have other devices twice the distance from my router on 1GB internet go I know it’s not an internet issue. Other than these 2 problems, it’s an overall decent tv that you could buy the cheaper versions and get the same results

    We purchased the TV around October of 2020. We have had multiple issues with the TV.
    1. Back light array not shutting off after powering down the TV.
    2. Unbalanced sound volume. Often the sound when you power on the TV is too low at level 20, have to turn the TV up to level 50, power on the TV the next time, and it’s blaring and you have to turn it back down again.
    3. Blurry vertical lines appear every few days and then the screen will go black for about 30sec to a minute, refresh and the lines will be gone. Overall the picture quality is not as good as other TV’s and not even close to the 55inch Vizio I’ve had prior to this one.
    I’ve had to factory reset the TV multiple times. Due to the fact that it wasn’t receiving updates even though it is connected through wifi. Once reset, you can go through the set up and it will magically find the update. I would not recommend this TV.

  9. Cid2042

    It’s been two months and I’m filled with regrets. If you’re a gamer this tv is terrible. Vizio stated the tv does 120hz on hdmi 3 and 4 but if you have anything over 60hz there is problems with the image. Often hdmi loses picture or sound. Tv needs to have hdmi restarted if resolution changes or hdr is enabled or not.

  10. Davescobales

    Constant video and audio issues. I have to power down the TV when switching from gaming to streaming devices or else audio doesn’t work. I’ve hard reset the television 6 or 7 times since purchase. TV is a beast when functioning properly but every now and then I’ll have to reset it to get it back to working. HDR issues with PS5. 120fps is great. Smartcast is a lot better than previous year but still laggy. Remote control is a waste. Extremely unresponsive. The remote control on the smartcast app is 10xs better. Would not recommend. Hopefully next models are better.

  11. Klauf

    This tv has been really frustrating. Super slow response times, sometimes it won’t even turn on, or it will turn on and then turn right back off. The smart cast system works like 10% of the time (ie Netflix, Disney , etc). The remote is clunky.

  12. telteknv

    We have 4 Vizio TV’s and a Elevate Sound Bar. Everything works great. If you have any problems or Questions ,you can contact Customer Service in just a few minutes to get help.

  13. MGiE

    It is my first 85″ TV. Love the picture quality, the thin bezel frame, and other features on this TV. Best available TV considering its reasonable price.

  14. EpsilonSix

    I’ve had the TV for a couple of weeks now. The picture is amazing with my Apple TV. SmartCast works wonderful. Apple TV App has a little less functionality then I was hoping… doesn’t integrate with HomePods without the Apple TV.

  15. ramon2405

    the remote is non-repsonsive a lot of the time….i downloaded the remote app for my phone but that was non-funcitonal as well so I deleted it. i like the picture but the remote is a deal breaker for me…i will probably not get another visio when the time comes

  16. Bori6bc212

    Best price for this size of TV, also my next gen systems are loving my Vizio as am I. Watching movies are beat though iTunes for me especially with the blacks (HDR) in movies like the Matrix, Batman and any movies that are dark and heavy with black backgrounds. I wish there were more apps like HBOMax but all in all great buy!!!

  17. Cronek28

    Wanted to upgrade and future proof in the process. The picture quality is great, the colors are amazing and it gets super bright which helps in my living room that has a bunch of windows!!! I love that it supports all the HDR formats and is ready for next gen gaming consoles. Basically lots of features at a good price. I’m happy!

  18. Burn

    The only thing I’m having trouble with is the HDMI/HDCP handshake between my a Onkyo receiver, my Xbox One X and the Audio Passthrough. I’d love to just push video to my TV through the Receiver, and let it handle everything else, but I can’t. Probably going to be a problem with any more modern TV, and it works nearly perfectly if I just connect stuff to the TV and run the connection via ARC to the receiver. Not ideal, but it works.

  19. s8432

    I bought this television a month ago and it is vivid and clear.. I am in love with this television. I can easily switch between Netflix or Amazon or Hulu right on the remote… I am extremely pleased!!! We have had other televisions from other manufactures and we keep coming back to the Vizio.. I really am impressed and like this brand and my model.

  20. Doe119

    I am extremely happy to have made this purchase. It’s is the biggest TV screen I have owned to date and I love the amount of detail I can see now that I have missed with my old TV. I also purchased the Vizio sounder with the surround sound and it is amazing.
