Sony X900E - Dolby Vision Question

Im trying to choose between the P65-E1 and x900E--leaning toward the x900E. My only hesitancy is that the x900E doesnt support Dolby Vision. Although the Vizio has Dolby Vision, what does having it matter if the Vizio doesnt have as wide a wide color gamut and doesnt get as bright as the x900E. Streaming the same 4k movie one in Dolby Vision to the P65-E1 and one in HDR10 to the x900E, wouldn't the picture quality, brightness, color, etc still be better on the x900E if the Vizio cant take full advantage of Dolby Vision by being limited to its WCG and peak brightness?

From what I have read, it is the other way around. Less bright TVs/poorer tone mapping are the TVs that would benefit from Dolby Vision more. The X900E might be in the middle as far as benefiting since it does not peak over 1000 nits but gets close. Sony should have put Dolby Vision on it instead of the X930E or Z9D, neither of which likely need it.

Read this article's conclusion: http://www.hdtvtest.co.uk/news/dolby...1606214303.htm


In other words, Dolby Vision pulled ahead of HDR10 4K Blu-ray when the display featured suboptimal peak brightness/ colour volume/ tone-mapping, but the gap was closed to negligible levels by a high-end HDR TV with 1000+ nit peak luminance and accurate tone-mapping. Future developments like dynamic metadata for HDR10 (as demonstrated by Samsung at NAB 2016) may level the playing field or even swing things in favour of the open standard.

Perhaps the greatest appeal of Dolby Vision is the promise of high-quality HDR performance on low-cost and midrange televisions, allowing shrewd video enthusiasts to save some money in the pursuit of better home cinema experience, though any possible savings may be partially offset by the potentially higher prices of DV-enabled Ultra HD Blu-ray players (due to the licensing fees payable to Dolby Laboratories) when they’re launched. Exciting (if uncertain) times ahead…

Thank you. It ultimately sounds like there won't be a significant difference between the two--Vizio P series streaming DV and X900E streaming HDR10. And, there isn't a ton of DV content currently available anyway. Saw both tvs in the store and both look outstanding. The Sony looked a bit better. But they werent showing the same video and i doubt either were calibrated to their potential.

Is it true Sony is planning to roll out a firmware update to unlock Dolby Vision on the x900e?

This is per a Best Buy sales rep I spoke with last week. Seems fishy to me but I thought I would ask the forum, thanks.

I've had the P65 for a year now. Great TV, especially in a dark room. That being said, if I could do it all over again, I'd spend more on a TV with a wider color gamut and higher peak brightness, as long as the blacks aren't destroyed like on a Samsung KS.

I'd go with the Sony if I were you. Dolby Vision IMO is overrated when compared to HDR 10, there's hardly any difference, especially with the lower brightness and colors on the Vizio.

Just talked to Sony support and they said that with the next update that Dolby Vision will be able to be unlocked. However did they did not have a date for such update to roll out.

It seems to me that the TCL P607 fits between the Vizio P and the Sony 900E and costs far less than either of the two. Unless you need the tv right now (65" not yet available) I think you might want to consider it. Check Rtings review of the Vizio 2017 P series to see their comparison- they recommend the TCL over the Vizio.

You can call me Sheila.

That's great news if accurate. Will make buying decisions much easier between these 2 TV's and hurt Vizio with their decision to not improve the P series. One thing I've learned the hard way is never buy on a promise!

For what it's worth, I contacted Sony support after reading this and this is what I got:

I am sorry to inform you that currently the TV supports HDR10 but have we do not information on a future update release for Dolby vision

I hope what you heard is correct.

I got similar reply.

"As per the update we have received from our Engineering team, the feature should be available with the next firmware update."

Well, this is dang confusing. All the reports were that because the 900E does NOT have the X1-Extreme processor, it could never be DV capable. What the story here?

I read earlier that Dolby Vision no longer needs special hardware. If true, that could explain why they'd be able to add it to the 900e... if they're actually going to.

This is the most misinformed myth out there. The lingo was very vague. They said that technically in Theory the decoding can be added via firmware. But what alot of people didn't realize is that the actual processing and displaying of the information by the tv has very high standards and requires heavy processing power. So if you get what I mean, for example, a system like a ps4 pro can be updated to decode and pass Dolby Vision, which is different than the actual TV decoding and accurately rendering it on the screen.

Any updates on this?? Been about a month since the last post in this thread and was wondering if Dolby Vision is going to be added or not. Since I've not actually seen what Dolby Vision looks like I am quite curious how it does actually compare to regular 4k HDR blu-rays.

Technical reports, from a web search ofreliable reviewers, suggest that only Sony TV's with the X1 Extreme processor will support Dolby Vision HDR. The X900E has the standard X1 processor and not the X1 Extreme processor, so DV cannot be added.

So dumb question then. Does AT4 decide DV or pass it? I guess if the streamer decides it who cares about the TV, but I am going to assume the streamers will just pass it and leave it to the TV?

Doing dolby vision in software requires a powerful SOC, this is why you are seeing it pop up on some higher end TVs with faster processors this year. Ironically these TVs are the ones that need it least.

I've been reading this same info as well but I am skeptical. I find it hard to believe that the highly regarded "X1" cannot handle DV but an M-Series Vizio has a powerful enough processor to do it?!?

Why not? Vizio had DV in mind from the get go, actually Vizio displays didn't even support HDR10 at all when they were first released.
DV for Sony is an afterthought and they'll be using DV's software implementation, which requires massive processing power. So it's quite possible that the regular X1 is just not fast enough, while the X1 extreme is.

LG 65B7 | T95N with CoreELEC | Vizio SB3851-D0 | Calibration + Settings (TBD)
Vizio M60-D1 | T95M with LibreELEC | Calibration + Settings
Dell UP2516D | Le Potato with CoreELEC (Development/testing platform)
Vizio M55-C2 (Ex) | Calibration + Settings

Because that's what the 940e model is for.....

Because Vizio has a separate processor for DV.

It does both. The TV has to have DV support no matter if its just displaying it or processing and displaying it.
