Sony-XBR65Z9D-side.jpgPerformance
As always, I began my official evaluation by measuring the Sony's different picture modes as they come out of the box to see which is the closest to reference HD standards. The XBR-65Z9D has a lot of picture modes, and I confess I did not measure all the ones aimed at photos, graphics, animation, and sports. Instead, I focused on the Vivid, Standard, Custom, and Cinema modes. Sony describes the XBR-65Z9D as a "prosumer" display, meaning it's designed for use as both a professional studio monitor and a consumer TV. Sony recommends the Custom mode for professional use and the Cinema Home and Cinema Pro modes for consumer use. I obtained similar white balance and color measurements in all three of these modes, so I followed Sony's recommendation and chose the Cinema Pro mode for nighttime movie watching and Cinema Home for daytime TV.

I performed my official calibration in the Cinema Pro mode. Its pre-calibration numbers were good but not excellent. Its light output was a very high 139 foot-lamberts, which I think is much too bright for nighttime movie watching. I had to dial the backlight brightness way, way down to a setting of 6 (out of 50) to get to more comfortable 45 ft-L. The maximum grayscale Delta Error was 6.3: the white balance was a bit too cool (or blue) at the brighter end of the spectrum, and the gamma average was 2.5. The calibration process yielded excellent results: a maximum Delta Error of 1.3 and a gamma average of 2.26.

In terms of color accuracy, the least accurate colors before calibration were blue and cyan, which had Delta Errors of 3.43 and 4.01, respectively. Those are very good out-of-the-box numbers. As I mentioned above, there's no color management system to fine-tune the color points, but the act of adjusting all the other image parameters (white balance, gamma, and light output) actually improved the accuracy of almost all the color points when I was finished. In the end, red was the least accurate, with a DE of just 1.9. So, Sony was right--I didn't miss the CMS because I didn't need it. (See the Measurements section below for more information on our measurement process.)

The main differences between the Cinema Home and Cinema Pro modes are in the areas of light output and gamma. The Cinema Home mode measured a very bright 151 ft-L, yet its gamma still tracked right along the 2.2 gamma curve. Combine that with its fairly neutral color temp and accurate color points, and it's pretty much good to go right out of the box as a great daytime TV-watching mode (although I did choose to turn off a lot of features--like Motionflow, Live Color, and Contrast Enhancer--that are turned on by default). The XBR-65Z9D's screen is reflective and does a great job of rejecting ambient light to keep the image contrast high in a bright room. Its reflective nature means that you will see room reflections, so you'll need to be mindful of where you place lamps and other light sources in relation to the screen. The TV's viewing angle is better than average for an LCD.

Overall, the XBR-65Z9D is the brightest TV I've ever measured; its brightest picture mode is the Vivid mode, which measured 210 ft-L with a full white field. Compare that with Samsung's current flagship UN65KS9800, which maxed out at 182 ft-L in Dynamic mode. Light output is an important parameter for HDR content; in HDR mode, the XBR-65Z9D measured roughly 1,800 nits with a 100-IRE pattern in a 10 percent window, while my reference LG 65EF9500 OLED measured only 428 nits with the same pattern. Newer LG OLEDs are brighter than my 2015 model, but they still can't rival LCD in this area.

In my book, all that brightness means very little if the TV underperforms in the black-level department. And it's in this department where the Sony really struts its stuff, besting every LED/LCD TV I've tested. As I ran through black-level demos from The Bourne Supremacy (DVD), Flags of Our Fathers (BD), Gravity (BD), The Revenant (UHD), and Batman vs. Superman (UHD), the Sony TV absolutely kept pace with the LG OLED in its depth of black, and its shadow detail was a little better. At times the Sony's deepest blacks looked just a little bluish, even after calibration. Brightness uniformity around the screen was excellent, and the halo effect (or the glow you see around bright objects in a local-dimming-equipped LED/LCD) was a non-issue. Sure, there were instances, especially with white text on a black background, where I could see a hint of glow, but it was so minor as to be inconsequential--unlike the Samsung KS9800, which really struggled in the halo department.

As I moved from one UHD disc to another--including Billy Lynn's Long Halftime Walk, Batman vs. Superman, Sicario, The Revenant, and The Magnificent Seven--I was simply enthralled with the XBR-65Z9D's picture quality. It was gorgeous in every respect: the level of detail was exceptional, the color was wonderfully rich, and the picture was very clean. There are two areas, in particular, where it distinguished itself from my reference LG 65EF9500 OLED. The first, and most obvious, is in its brightness with HDR content. The fire and moonlight glow in The Revenant, the explosions and eye lasers in Batman vs. Superman, the fireworks of Billy Lynn's Long Halftime Walk--all those elements popped in a way that the OLED couldn't match.

A more subtle but just-as-meaningful difference is in the processing. My one knock on the LG TV when I reviewed it was that its processing wasn't as good as it should be for a higher-end TV, and I saw this play out in comparison with the Sony. For instance, at the 1:27:36 mark in Sicario, an agent enters a dark tunnel, silhouetted against the dark blue sky. On the Sony, everything looked clean, and the black areas were perfectly black. On the LG, the black areas were filled with noise and banding issues. I saw something similar starting at the 24:18 mark in the Gravity BD, as the light from the sun transitions to the dark of space. The Sony produced a mostly smooth transition, while the LG produced obvious rainbow-shaped steps from light to dark.

I also saw color shifting issues. In chapter five of the Flags of Our Fathers BD, the men sit on the boat's deck on a foggy evening. With the LG, I could see reds and greens in the grey fog, whereas the Sony was clean. At the 2:43:18 mark in Batman vs Superman, we see a simple shot of the empty Daily Planet office: in the white ceiling surrounding the long overhead fluorescent light, the LG again showed a lot of red and green bands, while the Sony had a cleaner white.

Don't misunderstand: Much of the time, both of these TVs look fantastic. But there were definitely a few instances where the Sony had a real advantage, beyond just its higher light output. Hopefully I'll get my hands on a newer 2017 OLED and see where it stands in the brightness and processing departments.

A few more quick observations about the XBR-65Z9D. The Motionflow menu includes a variety of ways to address motion blur and judder: I preferred the Clear mode, which does a great job preserving motion resolution without adding the smoothing function--but there's also a custom mode in which you can independently adjust the blur and judder controls. The TV passed most 480i and 1080i deinterlacing tests; it was a little slow to detect the 3:2 film cadence in 480i DVDs, so I occasionally saw some moire and jaggies at the start of scenes. Overall, the Sony and Oppo Ultra HD players did a slightly better job with both the deinterlacing and upconversion of DVDs. Finally, 3D content looked good. The TV has ample brightness for 3D, and I didn't see any obvious ghosting issues--although I did notice a lot of flicker in the supplied glasses.

Measurements
Here are the measurement charts for the Sony XBR-65Z9D, created using Portrait Displays' Spectracal CalMAN software. These measurements show how close the display gets to our current HDTV standards. For both gray scale and color, a Delta Error under 10 is considered tolerable, under five is considered good, and under three is considered imperceptible to the human eye.

The top charts show the projector's color balance, gamma, and total gray-scale Delta Error, below and after calibration in the Cinema Pro mode. Ideally, the red, green, and blue lines will be as close together as possible to reflect a neutral color/white balance. We currently use a gamma target of 2.2 for HDTVs and 2.4 for projectors. The bottom charts show where the six color points fall on the Rec 709 triangle, as well as the luminance (brightness) error and total Delta Error for each color point.

Sony-Z9D-Custom-EOTF.jpgWe also measured the TV in HDR mode. The XBR-65Z9D's most accurate picture mode for HDR was the Custom mode. It measures a maximum brightness of 1,846 nits at 100 IRE in a 10 percent window. To the right, the top chart shows the Custom mode's EOTF (aka the "new gamma") tracking; the yellow line is the target, and the Sony (gray line) measures very close to it, but just a little over-luminance in the 50- to 80-IRE range.

The bottom chart shows the full Rec 2020 color triangle, with the target points being set for DCI-P3 color (currently, no TVs can do full Rec 2020 color). Each white square is the target at a certain Sony-Z9D-Custom-P3.jpgsaturation level for each color. This TV falls slightly short of the full P3 color space, although similar to other UHD TVs we've measured.

The Downside
For a flagship display, there's nothing especially noteworthy about the aesthetics or sound system of the XBR-65Z9D. LG's new OLEDs have a cool picture-on-glass design and, of course, are thinner and lighter; they also come with soundbars (with Atmos support in some). VIZIO's 65-inch Reference Series TV comes with soundbar, sub, and dedicated surrounds. Granted, most people shopping in this price range will (hopefully) also have a good multichannel speaker system in place.

The Android TV platform has become as fully featured as its rivals, and the convenience of Chrome Cast is great. However, because there are so many different ways to navigate this TV and browse content, the overall user experience doesn't feel as intuitive and well integrated as other smart TV platforms I've auditioned. Samsung and LG have really put a lot of design effort into minimizing the number of steps, layers, and button pushes you need to move from one screen or service to another, whereas Sony's interface fells a lot more cluttered and step-heavy.

My last comment falls firmly in the nitpick category, but I just have to mention something about the picture controls. Sony has changed the names of two standard picture adjustments. In pretty much every LCD TV, the adjustable backlight control is called Backlight, while the Brightness control adjusts the level of black in the signal. In this TV, the Brightness control adjusts the backlight, and the Black Level control adjusts the level of black. Now, those names may very well be a more accurate reflection of what's being adjusted, but it's just going trip up calibrators and videophiles who are used to the existing nomenclature.

Comparison & Competition
One competitor, pricewise, is VIZIO's Reference Series RS65-B2. It's also a full-array LED/LCD TV with 384 dimmable zones but only rated at 800 nits of light output. It supports both Dolby Vision and HDR10 and costs $5,999.99.

LG's new 2017 OLED lineup is reportedly brighter than past models, and the performance should be similar across the whole line. All of them support Dolby Vision and HDR10. The different series offer different design and feature options. The top-shelf Signature OLED65W7P has an MSRP of $7,999, the OLED65G7P is $6,999, the OLED65E7P is $5,999, and the OLED65C7P is $4,999. (Those are early MSRPs; we'll see if the prices drop when the TVs actually ship.)

Samsung's 2016 flagship is the full-array UN65KS9800 (which is curved, see my review here), and it now sells for $3,000. It's a very good performer, but really not to the same level as the Sony. The new 2017 flagship QN65Q9F will use edge LED lighting and Samsung's newly enhanced quantum dot technology to supposedly improve light efficiency, stability, and viewing angle. It has a starting MSRP of $5,999.99.

Obviously, Sony's own XBR-65A1E OLED, at $6,499, will also be a competitor.

Conclusion
If I may quote Neil Diamond (or The Monkees), I'm a believer. Sony's XBR-65Z9D is simply a fantastic Ultra HD TV that excels in every performance category. Now that I've seen it in action myself, I understand why Sony intends to keep it at the top of the line. Whether you're watching HDTV, DVD, or UHD, in a sun-drenched room or a completely light-controlled theater, this TV will deliver. Yes, it's expensive, and yes there are more affordable, well-performing choices out there that will suffice for a vast majority of people. But if you want the absolute best and brightest available on the market today to bring your new Ultra HD collection to life, the Sony Z9 is it.
