I've already processed my exchange with Costco. Hopefully the new one does not have this issue. I'll be sure to update after I have the new one set up and tested.

Poor upscale on regular Blu-ray

I have had the 75" version for a few months, aside from minor DSE, poor viewing angle and some other minor annoyances, this TV has been great. However, I've found out that upscale from regular Blu-ray is very poor. Whether I am up scaling in the 4K player (Sony X800 M2) or the TV, the results are the same. People's faces gets smeared in motion, a lot of times the shape also shifts in and out like morphing. This is especially true in dark scenes. Upscale from online streaming works great though, no issues found. I have changed a bunch of settings to try to resolve this to no avail. Any ideas?

720P upscaling is considered to be a Vizio weak point overall. And since some Blurays are 720P, you're probably seeing it. Not all Blurays are 720P though, I'd check some higher resolution discs.

These are all 1080p FHD discs.

If direct TV streaming looks better than external sources, then I would suggest you focus on investigating the external device as the most likely cause. Maybe it is an settings issue with the Blu-ray device. Maybe it needs a new firmware update or factory reset. Also make sure Full UHD color is enabled for that HDMI port on the TV.

Also note that picture mode settings are independent for each HDMI input on the TV. Make sure that isn't the issue.

Why are these TV's so damn slow to boot up. My Samsung is on in a couple seconds. This thing takes 20-30 seconds and you are left wondering is the thing going to turn on?

Just an update that I tested running my devices through an HDCP 2.2 compatible HDMI matrix before going to the TV. The matrix then fed audio back to my receiver. And...the issue went away. Just one more piece of evidence that the issue is indeed originating from the TV. The only question now is if the issue exists on my TV exclusively, or if it's an issue that exists universally on this particular make and model of television. My replacement is supposed to be arriving this upcoming week so I should have an answer to that shortly.

Do you get the audio dropouts when using the native apps, outputting via ARC?

There is a setting in the TV's menu that allows you to switch between "Eco Mode" or "Quick Start Mode". The television is set to "Eco Mode" by default and is supposed to use less energy when idle. "Quick Start Mode" will allow the TV to power on faster.

That's a good question. I actually hadn't tested that. I have an Amazon Fire for my streaming needs, so I don't really see myself using the TV's native apps very often if ever.

Try it and see if it works. If it works properly, that suggests that your TV cannot pass DD from external devices (through the HDMI ports)

It would appear that the audio seems to work when using the built in apps. Granted, I didn't watch for an extra long period of time. But normally I feel I would have noticed at least one or two dropouts in the time that I was watching.

When I got the tv I used stereomandan's recommended settings and pulled up greyscale videos on YouTube, I didn't have any dse or dark areas, no halos around subtitles or white areas, no tv randomly turning on, I'm using new HDMI cables from monoprice, got a new avr that does hdcp 2.2 blah blah I was expecting a nightmare but it's the exact opposite. This forum is great for advice but I think it really is just a small group of 50 or so anal people / people with defective sets posting here out of thousands who have good ones with no issues. I highly recommend this tv but get it on sale, msrp too high imo. Seriously loving it, and I'm happy that you're happy as well!
Hey, can you provide a link to the settings?

I have the Pioneer LX500 and not had any video issues on my Vizio and I believe I'm letting the TV do the upscaling.

So I was messing around with some settings to try and figure out how to get this issue to go away. When I turned "Game Low Latency" on, the issue seemed to go away. So that's...interesting. That setting is mainly meant to be used for reducing input lag while gaming. I don't really see that as a solution so much as a band aid. But it appears that there is some processing being done by the TV that is causing this "blending/ghosting" to occur. I'm just not sure what processing yet or how to isolate it and shut it off.

I think I've figured it out. In the "Reduce Noise" section of the picture menu, there is an option called "Reduce Signal Noise". The television's default setting is to have this at low. I turned it off and the problem appears to have gone away. My guess is that the TV was interpreting the film grain from the darker scenes as "noise" and was attempting to clean it up. This was causing artifacts in the moving image. Try that James and see if it solves your issue on your 75" as well.

I have a 75" Quantum X with a few issues. Hoping someone may have a solution to one or more of these problems.

Backlight Lag:
During scenes changes from light-dark or vice-versa, the backlight lags behind a few frames, and is very distracting. This happens more on HDR content. I also notice the backlight in certain areas of the screen will jump sharply lighter or darker on their own, instead of smooth transitions. This is especially noticeable when watching widescreen content. Full active array is set to low for both SDR and HDR. Medium makes it even worse.

Jailbars:
I am seeing the FALD very clearly in lighter areas of the screen, especially during pans of sky. Enhanced viewing angle is set to ON.

ARC:
I have the TV connected to a Onkyo receiver, which is then connected to an Apple TV and a PS4. Both the Apple TV and the PS4 will turn on the TV, but neither will turn it off. Furthermore, if I try to turn off the TV on the PS4 input, it will turn back on after a few seconds. I can only fully turn the TV off if it is on the Apple TV input.

Thank you for the help!
Brandon

Setting the FALD to low for HDR completely defeats the purpose of having this TV. The maximum luminance is reduced to below 1000nits. In order for the TV to maximize it's output and follow the EOTF it should be left at medium. Backlight lag might be solved by performing a factory reset of the TV. Make sure it is on the latest firmware before doing so.

Jailbars: What you are describing does not sound like FALD jailbars. The way you describe it seems like DSE. All LCD/LED panels ever created have some level of DSE. There isn't a single company that has been able to crack the uniformity issue. Some panels may be obvious while others are not noticable at all. If it is bad enough for your panel then it may warrant an exchange. Many unbiased reviewers have shown through testing that the "Enhanced Viewing Angle" is not useful at all and should be left off.

ARC + CEC: does not have a set standard for compatibility. Nearly all manufacturers have their own implementation that may not work with other connected devices. Onkyo has been a hot topic in the Vizio threads as one of the receiver brands to have these kinds of issues. Check to see if the receiver has a firmware update that might improve CEC
Alternatively you could connect the media devices to the TV. The TV will route the audio to the receiver via ARC with HDMI1.

Got my replacement PX65-G1 today and just finished setting it up. Unfortunately I'm getting the same audio dropouts from the digital out on this one as I was on the previous one. At this point I have exhausted all other possibilities. I know that the audio issue is somehow originating from the TV because it's the one device within the connection that introduces this flaw. If I take the TV out of the equation, the audio dropouts go away. If I add the TV back into the stream of connected devices, I get dropouts. It is a little perplexing that the issue is present on both HDMI/ARC and optical. However, since the same issue is present on two separate televisions, I can rule out the possibility that it is a defect and can instead call this a flaw in the design itself. That being said, I love the TV for it's picture and have developed a workaround for the audio problem. Using an inexpensive HDCP 2.2 compliant HDMI matrix with audio extraction, I am able to connect my 4K and HDR capable devices and get audio back to my AV receiver before the TV is able to introduce the problem. It's somewhat disappointing that I can't just use the PX65 for this, but it is what it is. For anybody else who might be experiencing this issue, an obvious solution would be to purchase a new HDCP 2.2 4K and HDR compatible AV receiver. Short of that, the addition of the Matrix is a cost effective and viable solution.

Sounds like the PQX doesn't support DD passthrough from external devices to ARC. You might want to check if others are able to. If this is the case, the PQX wouldn't be the first TV to have limited pass through from external devices.

Not that I want to try and read all the pages of post, What is everyone's take on this this looking to replace my E6 OLED my 3yr old broke it a few months back.. Has Vizio sorted out their problems viewing from cable? I remember I tried the P series from 2016 i believe and while netflix and what not looked good on cable looked washed out and whites were blown out

Not true, while it can be finicky (I simply reboot the stick if drop outs occur) I get DD pass through via ARC from my Fire TV Stick 4k and it works via my Denon receiver. The receiver absolutely shows DD is being received.

In that case the OP got another defective unit

This is correct for me as well. Technically it "works" just not very well at all. My Sony STR-DN1040 properly reads and shows all of the formats when it receives them. Anything hooked directly to the receiver is flawless...no problems at all. My current setup (with the 4K and HDR devices going through the Matrix) is flawless...no problems at all. The problems only occur when I pass the signal through the TV first. Again, while it technically "works" it just doesn't work well. Dropouts aren't overly frequent (about every 10 minutes maybe) and they aren't long (lasting a fraction of a second). However, they are frequent enough to be annoying. Ultimately I don't really care whether or not the TV is capable of passing a digital audio signal either through HDMI or optical. I do however care that the manufacturer claims that it can do this and lists it as a feature. If the device isn't able to do it well, if it can't do a consistent and solid signal to it's destination then there's really no point to have it at all. From my experience, the PCM output seems to work fine. This is great if you're setting up a 2.0 soundbar, but not if you have an AV receiver with a surround setup. It's disappointing mainly because I've never had this much trouble getting a device to simply do what it claims it can do.

Actually, I am able to watch everything completely with no dropouts once I reset it. Usually only happens when I switch from a different device. I stream movies shows all the time with no dropouts. Like I said, usually rebooting the fire stick fixes it.

Yeah, I've tried everything. Power cycles, factory resets, new cables, new power supplies, every possible combination of settings....nothing works. I stated on previous postings that I initially thought that it might have been some kind of HDCP or handshake compatibility issue with the HDMI/ARC. However, that doesn't explain why the same issue is present when I tried sending the audio out through toslink/optical. Theoretically that should just be sending the digital stream from the TV to the receiver. There really shouldn't be any compatibility issue with that particular setup. What that says to me is that the audio decoding/encoding hardware/software in the TV is either really cheap or just flawed by design. Like I said, PCM seems to work fine, so it's not an input issue. It's purely a decoding/encoding and output issue. I think that certain makes and models of AV receivers are going to be more forgiving of the unreliable digital output. However, that doesn't mean that the digital output isn't still flawed in some way. At the end of the day, I'm still going to keep the TV. The picture quality is great, and I have a workaround for the audio issue. Originally I just wanted to see if anybody else was having a similar problem. Now if somebody else does encounter similar issues, then I'm happy to provide a possible solution.

I think I've noticed this as well, at least for OTA. I've been happy all along with how it upscales for 1080p Bluray.
