VIZIO P-Series Quantum X vs Hisense U9 Series: Which 4K TV Offers Superior Smart Features and Gaming Performance?

[Barend Ray]

Today, we’re diving into a head-to-head comparison of two heavyweights in the TV market: the VIZIO P-Series Quantum X and the Hisense U9 Series. At first glance, both models promise exceptional picture quality, but they take very different approaches to achieve it.

On one side, we have the VIZIO P-Series Quantum X, boasting Dolby Vision HDR and a powerful IQ Ultra processor designed for top-tier image processing and 4K upscaling. With over 8 million pixels, it aims to deliver stunning detail and vibrant colors that pop off the screen.

On the other hand, the Hisense U9 Series features Mini-LED X technology, which utilizes thousands of pinpoint LEDs and up to 5,000 local dimming zones. This means you get to experience extreme contrast and a broader range of colors thanks to its QLED Quantum Dot technology. Plus, the Hi-View Engine X adapts the picture settings in real-time for optimal viewing.

So, which TV truly delivers the best viewing experience? Is the advanced processing power of the VIZIO worth the hype, or does the innovative lighting and color capabilities of the Hisense provide the edge? Let’s break it down.

Side-by-Side Comparison​

System Experience​

Parameter	VIZIO P-Series Quantum X TV​	Hisense U9 Series TV​
System Experience	Setting up the VIZIO P-Series Quantum X TV was a surprisingly straightforward experience for me. I was a bit apprehensive, especially given its size at 75 inches, but the delivery was smooth and the instructions were clear. I had a friend help me lift it onto the TV bench, and we took our time to make sure everything was done right. I work in AV, so I navigated through the setup without much hassle, but I can see how someone less tech-savvy might find it a little daunting. I appreciated that it walked me through the initial setup steps, making it user-friendly right from the start.	Setting up my Hisense U9 Series TV was surprisingly straightforward, which was a relief. I appreciated how user-friendly the initial configuration was, allowing me to dive right into the viewing experience without any unnecessary hassle. However, I did have a moment of frustration when I realized that shortly after my purchase, the price dropped significantly. It made me wish I had chosen a retailer that offered price matching, as the thought of returning the TV with all the original packaging was daunting, especially considering my age and health.

Viewing Experience​

Parameter	VIZIO P-Series Quantum X TV​	Hisense U9 Series TV​
Viewing Experience	Wow, the picture quality is simply stunning! Transitioning from HD to 4K made a world of difference, and the brightness of this TV is just phenomenal. I spent a considerable amount of time tweaking the display settings to match my personal preference, and I must say, it was worth every minute. The vibrant colors and sharp details completely enhance my viewing experience, whether I'm gaming on my Xbox or streaming movies on my Fire Cube. I particularly loved how well it handled bright scenes, though I noticed some minor blurring in high-contrast situations. However, I’ve learned to adjust my settings accordingly, and it’s a minor trade-off for such an incredible display.	The picture quality on this TV has genuinely impressed me. Coming from a Sony OLED, I was a bit skeptical at first, but the HDR performance truly took my breath away. Colors are vibrant, and the brightness is exceptional, making it perfect for my living room filled with natural light. However, I did notice that I needed to adjust the settings for different types of content, as some standard HD streams appeared overly bright under certain configurations. Overall, though, the clarity and depth of the image have made my movie nights much more enjoyable.

Audio Experience​

Parameter	VIZIO P-Series Quantum X TV​	Hisense U9 Series TV​
Audio Experience	I paired the TV with the Vizio Elevate Sound Bar, and together they create an immersive audio experience that truly complements the picture quality. The sound is clear and rich, bringing movies and games to life in a way that just feels complete. While I had some initial concerns about connectivity with the sound bar, overall, it works seamlessly. I no longer feel the need for multiple remotes, as voice commands simplify my entire experience and keep things easy when switching between devices.	While I haven’t focused too heavily on the sound quality, I can say that it’s decent for a television of this caliber. I tend to use external speakers for a fuller audio experience, so the TV’s built-in sound hasn’t been my primary concern. Still, it’s nice to know that it doesn’t detract from the overall experience when I do use it.

Other Experience​

Parameter	VIZIO P-Series Quantum X TV​	Hisense U9 Series TV​
Other Experience	I’ve noticed a couple of quirks with the SmartCast functionality. I don’t use it extensively, but I appreciate how it allows me to cast content without needing extra devices like an Apple TV. However, I did encounter some frustrating moments when using HDMI with my Verizon Fios setup; the TV would occasionally override my input selection, which could be annoying. I found that disabling the input switch on my set-top box helped alleviate that issue, but it would be nice if it were more intuitive right out of the box.	One thing I didn’t expect was how heavy this TV is! I definitely needed help to mount it properly. It’s a significant investment, and I was a bit nervous about handling it, but once it was up, it felt secure and solid. I’m also enjoying the integrated Google TV; it’s been seamless and convenient to have everything in one place.

VIZIO P-Series Quantum X TV：​

Pros:
The major pros for me include the incredible brightness and picture quality, which really elevate my viewing experience.

The size is perfect for my room, and the overall value compared to other high-end brands is impressive.

Cons:
On the downside, I have noticed some slight blurring in certain high-contrast scenes, particularly when gaming in darker environments.

I've also had moments where the TV would timeout or switch inputs unexpectedly, which can be frustrating during setup or when trying to enjoy a show.

Overall Evaluation:
Overall, I am genuinely happy with my purchase of the VIZIO P-Series Quantum X TV. It has transformed my entertainment setup, making movie nights and gaming sessions a whole new experience. Despite a few minor hiccups, the combination of stunning visuals, great sound, and the versatility of features makes it a worthy investment. I can’t wait to explore more content and truly enjoy what this TV has to offer.

Hisense U9 Series TV：​

Pros:
There’s a lot to love about the Hisense U9 Series. The picture quality is outstanding, especially in bright settings, and the vibrant colors make everything come alive. The two-year warranty is also a nice touch, giving me peace of mind about my investment. Additionally, the integration with Google TV has made my viewing experience much more streamlined.

Cons:
On the downside, I did find myself needing to tweak the picture settings more than I would have liked, which can be a bit of a hassle. The heavy weight of the TV also means it’s not the easiest to move or mount, especially without help. And while I haven’t experienced any major issues, the mixed reviews about the brand’s durability have made me a little wary.

Overall Evaluation:

So, I’ve got this VIZIO P-Series Quantum X TV, and let me tell you, it’s driving me nuts! It keeps dropping the connection to my sound bar. I can chill and watch a show with no issues, but as soon as I change the channel or turn off the TV, it’s like the sound bar just throws a tantrum and says “nope!” And don’t even get me started on Apple TV—it acts like they’re sworn enemies. Seriously, why can’t VIZIO just make this work already? So frustrating!

 

[JazzlikeCustard7611]

So, I recently picked up the Hisense U9 Series TV, and let me tell you, it’s a solid choice! The picture quality is top-notch, and setting it up was a breeze. But here's the kicker: just two days after I got it, I saw the price drop by a whopping $500 on Amazon! Can you believe that? And of course, Amazon doesn’t do price matching, not even for their own stuff.

Now, I could return the TV and snag the cheaper one, but that means I’d have to deal with all that packaging again. Considering I’m 77 and have a heart condition, moving all that stuff around is no walk in the park. Honestly, I’d really recommend buying from a place that does price matching, especially for big-ticket items like this. It’s way easier to return smaller stuff if you find a better price, which I’ve done before. I just don’t get their business model, but hey, it’s their game. Bottom line? I’m never buying a major appliance from Amazon again.

Man, let me tell you about this VIZIO P-Series Quantum X TV! It’s a beast—like, 75 inches of pure brightness! If you’re not used to big screens, it’ll definitely blow your mind.

I snagged this beauty along with the Vizio Elevate Sound Bar, and they’re like the ultimate dream team. Got it mainly for the Dolby Vision and Atmos features, and honestly, the price was way better than other high-end brands.

I’m mostly using it for binge-watching shows, movies on my Fire Cube, and gaming on the Xbox. If you’re picky about how things look, you’ll definitely want to mess around with the display settings for each input because it’s super customizable.

Now, I’ve got one little complaint: the active zones can sometimes give a blur effect when there’s a lot of contrast—especially in dark games or when there’s text on the screen. It’s not a deal-breaker for me, but you might notice it. If you’re curious about the best settings, check out RTINGS.

I don’t really mess with SmartCast much, but it’s cool not needing an Apple TV or Chromecast anymore to cast stuff. Works like a charm with the Fire Cube, which means I can ditch like six remotes and just use voice commands.

If you have Verizon Fios and are planning to use CEC to connect everything through HDMI, make sure to turn off the input switch on your set-top box. Otherwise, it’ll keep switching to Fios on you, and that’s just annoying.

Setting it up was pretty straightforward. One guy delivered it, and it took two of us to get it on the TV stand in our basement (not wall-mounted). Just be careful when you’re opening the box. Honestly, if I could do it again, I’d probably just pay for the installation because I was kinda nervous about breaking it (it’s huge!), but they packed it really well.

The setup wasn’t too tricky, but I work in AV, so it was a breeze for me. But don’t stress if tech isn’t your thing; the TV walks you through the initial setup.

Oh, and if you’re streaming, I’d recommend hardwiring for internet after you’ve set it up with Wi-Fi.

Overall, I’m pretty stoked with this purchase! I’ll keep you posted if anything changes!

Hisense U9 Series TV? Ugh, I’d give it a big fat zero if I could! Seriously, steer clear of Hisense TVs! I’m just a regular buyer, and mine crapped out on me after 18 months—right after the warranty ran out. It started acting up long before that, but they totally didn’t care to help. Now it's gonna cost me over a grand to fix this thing, so here I am, shopping for a new TV after less than two years!

Honestly, don’t go for the cheap stuff. New TVs can be a gamble, and as their supervisor put it, Hisense lifespans “can vary.” Mine sure did—down to nothing! I popped into Best Buy, and the rep told me to stick with the big three: Samsung, Sony, and LG. Man, I wish I had known that sooner. So please, do yourself a favor and skip the Hisense drama. Good luck out there!

Yo, gotta talk about the VIZIO P-Series Quantum X TV. The picture quality is amazing—seriously, the pics I shared don’t even come close to showing how good it looks!

Oh, and quick update! Some dude, AJB user, totally jacked my pics from my review. That’s my entertainment center, not his! Come on, Amazon, you gotta check into this guy and get those pics taken down!
