75" Vizio PX Series Quantum $1399 at Sam's In Store Only YMMV $1399.99

Per Rtings, a DSE tv. Just dont watch sports or any scene that pans like games.

Decent gray uniformity, but the sides of the screen are noticeably darker. There is also noticeable dirty screen effect (DSE) in the center of the screen, which isn't great for watching sports.

Yes, terrible 8.2 for sports on Rtings. With an overall 8.5 score, you should pass on this and pay $3500 for the 75 inch Samsung Q90 that scored a 8.7!

Buy the TV and run the tests. Just google Vizio PX and dirty screen and you see quite a few posts on AVS forum.

This is not some BS post. DSE is real and despite the great things about the TV which is true...the sad part is uniformity is a problem with all sets. I also picked edge lit and got a TV with near zero DSE. Go buy the TV...I dont care. you get a panel with DSE...have fun. I already dragged back my last TV to Costco with DSE. Right in the middle.

My advice is to buy 5 of the TV and return the one with best panel.

rtings sports is rated sports 7.9. Sports is rated for fast motion and other issues not just DSE. DSE is not just sports.

PROS
Great peak brightness.
Deep blacks and a great local dimming feature.
Outstanding wide color gamut.
CONS
Noticeable uniformity issues

Per forums.

I can see the grid pattern of the local dimming zones. It's the reason I returned my P75, as well as the vertical banding during panning shots. The picture was beautiful, don't get me wrong, but I couldn't get past these two issues which presented themselves over and over. It's true that they are only apparent in certain circumstances, such as a mostly white background or quick panning shots, but it was enough to bother me and I couldn't look past it. It all depends on what you can live with. I exchanged my old Vizio for a Samsung NU8000 and I couldn't be happier. It's edge lit, so many people will say don't go there... but there is no grid pattern and the vertical banding is essentially gone.

Are you sure you are looking at the same TV as the OP listed? The issues and numbers you are referencing are for the P Series Quantum. The OP is talking about the P Series Quantum X (PX).

There is a $500 difference between the two, and is like comparing a Samsung Q70 to a Q90.
Reflections are much better on the PX.
Sports is 8.3 vs 7.9 on the P series.
My only hesitation on picking this up is the bad viewing angle, which most LCD TV's have, except the Q90 and Q80

Here is a link comparing the 2.

Its not the score its the DSE. The P series is known for panel lottery.

Rtings
The Vizio P Series Quantum X is an excellent 4k LED LCD TV. ... There is also noticeable dirty screen effect (DSE) in the center of the screen,

its excellent tv BUT...it has DSE. I dont call that excellent but rtings does. I consider DSE to weigh more than 75% of the TV viewing. who wants a dirty screen?



Plus scaling issues.
720p content, like from a cable box, looks decent, but like other Vizio TVs we've tested, the image is a bit worse than most other TVs.

To be clear, the PX series is better than the P series in almost every category. Also, while it doesn't have the best gray uniformity, Rtings doesn't list it as a con for the PX.

I agree with the overall concept that you seem to be getting at, that if you don't get a good panel, and have DSE, there is a good chance a person won't be happy with the TV. That is true of any TV, and Vizio has stepped up their game to provide a more consistent panel. Infinitely better than TCL, which, along with Hisense, have the issue of being State Owned Enterprises by China, and I would never trust in my home, regardless of cost. Also, yes, 720p is not good. But at the very least, most TV services send programming at 1080i, which should equate to the 1080p rating for this purpose, though I cannot confirm that right now.

I actually have the NU8000 that you referenced, and while I like it, the local dimming is non-existent. I also think the reflections on it are pretty bad, though Rtings gave it a decent score.

I also have a 65 inch LG C9 which I love, but will not spend $4k for the 77 inch version for my rec room, and will not touch the LG SM8670 series which $1300 for 75 inch verison and has bad reviews, or as previously stated, the TCL and Hisense TV's due to China's ownership. So if I want a TV bigger than 65 inches, this seems like the best possible TV (at the discounted price) to fit my needs, or anyone else who wants a 75 inch TV that isn't lower quality or doesn't want to spend $4k.

I returned my NU8000 due to DSE. What is the panel version you have. Its 4 digits like FA01 or AD06. Samsung outsources panels so its a different panel lottery.

Regarding reflections..the TCL is really glossy (although nice screen).

I like to watch sports like football and hockey. DSE makes it impossible to enjoy. I got the NU740D from Costco with no DSE. Sure wish they could make panels without DSE.

If I could, I make is a law you cannot produce DSE panels. That would force manufacturers to work harder to create a good TV.

You dont see DSE on static images except white or gray solid color screens. Most people wont notice until you put on a sports event or do gaming.

Rtings does not put much value to DSE. I will never accept a TV with DSE.

When does the 85" come out?

I returned my NU8000 due to DSE. What is the panel version you have. Its 4 digits like FA01 or AD06. Samsung outsources panels so its a different panel lottery. My NU8000 was not a true Samsung panel. I got screwed.

Regarding reflections..the TCL is really glossy (although nice screen). Too bad about panel uniformity issues. Its really a great screen even on the 4 series.

I like to watch sports like football and hockey. DSE makes it impossible to enjoy. I got the NU740D from Costco with no DSE which is half 7000 and half 8000. Sure wish they could make panels without DSE.

If I could, I make is a law you cannot produce DSE panels. That would force manufacturers to work harder to create a good TV. Seems like old fashion edge lit TV has less DSE versus the fancy dimming TV.

From a person that owns a Plasma. No DSE. No blooming. No motion issues. No dead pixels. No flash lighting. And it acts as a heater in the winter time.
