Hdmi issues and bad image tearing
2 hours ago
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.

My best TV ever!
15 days ago
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.

Incredible Brightness and Blacks
1 month ago
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.

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.

This TV has Issues. Not worth the money
1 month ago
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.
