Sony XBR-65A8H OLED Ultra HDTV Review Test Bench

Test Bench

Measurements were made using CalMAN measurement software from Portrait Displays (, together with a Photo Research PR-650 spectroradiometer, a Klein K10 colorimeter, and a Fresco Six-G test pattern generator from Murideo/AVPro. The Sony XBR-65A8H is compatible with the auto calibration offered by CalMAN, but I chose to calibrate manually.

HD (1080p)/SDR

Full-On/Full-Off Contrast Ratio: unmeasurable

In Custom picture mode, with the Black level control at 50, Brightness at 40 (Max 50), Contrast at 92 (Max 100), Peak luminance at Medium, and Gamma at -2, peak brightness was 57.7 Foot-Lamberts (198 nits) with a 10% full white window. The post-calibration black level was too low to measure with our Klein colorimeter.

With Expert 1 Color temperature setting active, the pre-calibration grayscale Delta E (white balance) values ranged from a minimum of 0.14 at 100% to 1.23 at 60%. These out-of-the-box results were among the best I've ever experienced—perhaps even the best—so no calibration was really needed. But since the accuracy of Sony's processor-derived HDR calibration depends on the accuracy of the SDR calibration, I attempted to make improvements.

(Delta E is a figure of merit indicating how close the color comes to the D65 HD standard at each point in the brightness range. Values below 3—some experts allow for 4—are generally considered visually indistinguishable from ideal.)





The post-calibration results, using only the 10-point adjustments, resulted in a maximum grayscale Delta E of 0.88 at 40% and 60% and a minimum of 0.36 at 90% and 100%.

Before calibration, the color Delta Es varied from a minimum of 0.5 in green to a maximum of 2.18 in red. Post-calibration, the minimum was 0.5 in magenta and the maximum 1.24 in red. With the Gamma control set to -2, the Sony's gamma, both before and after calibration, correctly followed the BT.1886 standard for SDR sources.

The Sony's image lag, taken with a Leo Bodnar meter at 1080p, measured 110 ms in the Custom Picture Mode and 18.2 ms in Game mode.

The Sony passed all of our standard 1080i and 1080p video tests.

Ultra HD/HDR10

Full-On/Full-Off Contrast Ratio: unmeasurable

In Custom HDR Picture Mode with the Black level control at 50, Brightness at Max, Contrast at 92, Gamma at 0, and Peak luminance on High, the measured peak white level was 596.3 nits with a 10% white window and the black level 0.0004 nits. The latter number was the average of eight readings, and low enough to exceed the ability of our test tools to provide reliable measurements.

After calibration (using Sony's auto adaption of the SDR settings to HDR10) the maximum grayscale Delta E was 3.4 at 70% and no higher than 2.2 at any other level. Its maximum color Delta E values at 50% luminance were 3.8 for cyan and 3.4 for green, but below 2.6 for all other colors. The Sony closely followed the HDR PQ curve though with some minor deviations, primarily below 20%.

As with all OLED TVs, peak white output on the 65A8H, most significantly for HDR, varied with how much of the screen was producing a white image. A 2% full white window produced 660 nits, a 10% window 600 nits, a 25% window 420 nits, and a 100% window 140 nits.

Using the 1976 standards, the Sony's color gamut coverage was 74.4% of BT.2020 and 98.15% of P3.

Your review did not mention any offering of HDR10 Plus on this set, but I presume it has it because last year's model did. This is an advantage over the LG, which stubbornly does not offer it, and is one reason I would recommend this set over the LG. I presume also that the panel itself on this set is still made by LG, which was also not mentioned. The only difference is in the electronics applied to the panel.

Call me unreasonable, but my 75 inch Sony Z9D is sitting on a stand that's about 50 inches wide. Fortunately, I bought it before every TV manufacturer decided that every TV needs a soundbar sitting in front of it and therefore the legs need to be pushed all the way to the side (although the TV being reviewed isn't as bad as most sets now). Sony was nice enough at that time to let me spend $8000 on a TV without having to spend hundreds more on a stand to match the width.

I wasn't so lucky when I was shopping for a TV to replace a 43 inch Sony that was in my office that got zapped by a power surge. There wasn't even a 40 inch TV that was available that would fit on the stand I was using, so I moved a 40 inch TV from my guest bedroom to the office - one less TV sold.

How is ergonomics a category for rating a 65" TV that sits on a stand/wall??? Like....what is there about the ergonomics of a TV that you don't touch that could be worth providing a rating for? The remote control???

There's more to a set's ergonomics than merely its physical design. That includes, among other things, how the remote works and feels, how the menus are laid out, and ease of calibration.

Thanks for the reply!

How do these sets do with motion and how does it compare to the LG? I don't read much on OLED motion handling. Is it because it's a non issue?

The lack of HDMI 2.1 inputs I feel is a bad decision by Sony especially with the PS5 on the horizon. I have several gamer friends and they all say they're waiting for OLED sets with 2.1 for the variable frame rates it supports. As for HDR10+, the fact that it's a Samsung product almost guarantees that it will never be supported by Sony or LG. I for one would never consider buying a Samsung until it supports Dolby Vision. Speaking of supports, I have to agree with AlecS about these ridiculously wide stands/legs. I also own a 75" Z9D which sits comfortably on a 36" wide stand with room to spare.

S&V should do a blind comparison between the "bes"t LCD and OLED 4ks.
