Power Rangers 4K UHD (2017)

"Panasonic recently announced a new LCD panel arrangement which adds a per-pixel light-blanking layer between the LCD and the backlight which they claim improves native contrast at the pixel level. Whether it is truly LCD’s answer to OLED is something which we will find out in time."

The Dolby Pulsar is also a reference-worthy monitor that isn't even remotely comparable to consumer market LCD-panels. So, there is that.

That bit from hometheaterhifi.com above refers strictly to edge lit LCDs though. Most of the LCDs that are out there are edge-lit, true enough, but some folks have FALD TVs too - one of which is considered 'reference' enough to use as a client monitor in grading suites: https://forum.blu-ray.com/showthread...6#post13569326 - so it's best not to tar all LCDs with the same brush. As with a lot of stuff posted up in here that veers to one extreme or the other, the truth isn't always so black and white.

"Dolby’s patented dual modulation process is the key to how the Professional Reference Monitor provides unprecedented black levels, precise color accuracy at all luminance levels, and extended dynamic range. The modulated LCD, in concert with a dynamically modulated LED backlight unit, forms the dual modulation process that is directly responsible for the exceptional image quality.

The first element of dual modulation is the unique 12-bit backlight unit, consisting of approximately 1,500 RGB LED triads that directly illuminate the LCD panel. The monitor supports a wide variety of professional gamuts, including SMPTE C, EBU, Rec. 709, and DCI P3. Within each LED, the output of each R, G, and B element is dynamically modulated on a frame-by-frame basis with respect to the image content for each frame, controlled by more than 4,500 separate signals going to the backlight unit in real time. When the image requires that any portion of the screen go dark, the LEDs are dimmed, so that no light will pass through the LCD to the viewer. This delivers absolute black levels that challenge the accurate measurement capabilities of most instruments.

The backlight’s full-color backlight image is then modeled as part of the algorithm to generate the LCD image. The second element of dual modulation is the LCD panel itself, which is modulated in real time based on a complex algorithm composed of a variety of matrix and 2D filtering operations. The computational power that makes this modulation possible originally required nearly two TFLOPs to operate, but is now implemented in state-of-the-art, field programmable gate arrays (FPGAs)."

This thing might as well be self-emissive considering everything it has put into it.

By the way, that article also touches on FALD panels. The ones currently on the consumer market still don't cover enough zones to truly optimize HDR as a format.

Which goes back to my original comment of not wanting to go through the trouble have having to activate FALD, black-frame-insertion, and sitting at one angle to truly get a very good picture out of a technology that is becoming severely outdated.

Crazy people about Dobly Vision.

I don't have to 'activate' FALD nor do I use BFI as the motion on the ZD9 is A-OK with me, and I sit dead centre anyway. If I'm lying off to the side then whatever I'm watching I'm watching for the content, not the picture quality.

But yeah, the Pulsar is liquid cooled for a reason: it's a ****ing beast. Although the ZD9 has just under half the 'zones' and thus does almost 2000-nit peaks, it may not be the same thing but it's still a baby beast and it really does have some of the best processing available in consumer TVs today. Stacey Spears chose one as his HDR development monitor for that reason.

I mean, that's cool and all. I don't have anything against LCD owners. Even if I did, LCD panels are staying for the foreseeable future.

My point was, from the get go, that regardless of the peak brightness limitations of current OLED models, LG improved the tone-mapping drastically enough on the 2017 models, to the point that HDR10 looks very good on them. But, you can still see a difference in HDR10 to Dolby Vision. Which is really all I was trying to get across amidst some of the jackass statements from people that don't even possess the equipment to make these comparisons, whereas I can, regardless if people want to take my interpretations seriously or not. Their prerogative. But until they can come back with results from their own eyes, my opinions at least carry more weight than theirs.

By the way, if Panasonic could truly build a consumer market LCD-panel that could hit 'true black'--and if it supported DV--I would totally ditch OLED.

I love my KS8500. You paid at least $1k more for an OLED. It should be better.

...You don't even have an FALD panel. You don't have Dolby Vision. You're stuck with static HDR10.

You have the worst of the worst when it comes to an LCD. You can put lipstick on a pig; it's still a pig.

Does the digital movie redeem in HD or UHD? If we do it on Flixter, doesn't that give us a UHD in our UV library?

None of the latest Lionsgate new releases are available on Flixster so you can't redeem there. You have to redeem through vudu which gives HDX rights.

Who put the stick up his ass? And I quote... Who freaking cares? Do you really want to have a pissing contest right now because I can post some pictures of where my main movie watching is done that will bring your ego down a notch.

Looks like you should've allocated the funds you spent on your theatre setup towards a better education.

Looks like someone needs to buy some tampons. Good day sir.

Never seen this before on a UHD Disc and would not have noticed this in Despicable Me 1 and 2 in DV due to the aspect ratio.

I have noticed this myself on my C6. Go to the 5:10 timestamp and I am having a tough time getting the letterbox bars to absolute black on my OLED. I am going to try again tonight but I had to drop the brightness to 45 and I still don't think I had absolute black in DV Dark or Bright mode. Disabling DV and watching the film in HDR10 turning the HDR button to forced and turning the player off and on again the HDR10 is spot on in all modes with brightness at 50 for absolute black. I will retry this tonight as I am curious about DV bright mode as it doesn't use dynamic contrast like the HDR10 modes. I will report what I find later this evening to get 0 mll letterbox bars.

You may want to use DV Dark anyway, as that what Dolby suggests using to getting the best DV picture on that set.

I'm using the OPPO as well, but haven't had any issues with black uniformity on the letterbox bars.

Maybe a region issue?

What is your display?

Just finished watching Power Rangers. Aside from the fact that 7 year old me absolutely loved this movie (as does 30 year old me now) I can say I had no issues with the black bars being pitch black throughout the entire movie - Dolby Vision on all around.

My gear is my signature.

OH I SEE YOU GUYS ARE ARGUING

When did the 4K subforum become as uncivilized as the Bluray Movies subforum?

Ignore Lists for everyone!

Silly you for posting about the actual experience you had with the movie and the disc...

On a serious note, I was planning on renting this on Blu-ray and then buying the 4K release down the line, but I'm tempted to buy it now to watch it in 4K with the glowing reviews (that you can actually find, and obviously including the site's).
