Scorata scores summarize analyzed review evidence on a 1–5 scale; they are not laboratory measurements or a simple average of customer star ratings. Feature scores summarize the reviews covering that feature. The overall score averages feature scores within each review, then combines review averages. When both expert and customer evidence are available, those two groups receive equal weight. Products can have different review coverage, so small score gaps do not establish a winner.
Recommendations prioritize important features for the category, with a score of at least 3.5, a gap of at least 0.25 points and at least two supporting reviews per product. Features with widely varying scores or broad connectivity contexts are excluded from recommendations. These safeguards do not establish statistical significance.
Quick verdict
The review evidence points to a tradeoff: glare resistance and reflection handling versus motion handling and Dolby Vision support. Choose according to which strengths matter more to you; the overall score alone does not settle that choice.
Choose Samsung 77S90H OLED for glare resistance and reflection handling.
Choose Panasonic Z8BA OLED for motion handling and Dolby Vision support.
Scores are out of 5. Missing scores mean missing review evidence, not a missing feature.
Deep blacks, natural color and rich highlights give this 77-inch screen an excellent overall image.
Natural, rich OLED imagery is the headline attraction, tempered by dark-scene shimmer and comparatively limited brightness.
Bright daylight and nearby windows do little to spoil visibility, especially in scenes that would otherwise reflect the room.
The panel can struggle to maintain impact in strong daylight, especially with large bright areas like sports fields.
Compression problems such as posterization and macroblocking are not removed particularly well.
Compression cleanup is generally effective and preserves finer textures, although it does not eliminate every artifact.
Fine-tuning a good picture for both daylight and evening can require more work than expected.
There are many useful modes and adjustments, but some brightness-boosting choices noticeably compromise accuracy or saturation.
Near-perfect blacks make movies look dramatic in dark rooms, although vertical near-black bands prevent a flawless result.
In controlled light, the deep blacks, accurate colors and detailed shadows create a particularly cinematic image.
OLED brightness falls when much of the picture is bright, reducing impact in sunlit scenes or full-screen white imagery.
Large bright scenes expose aggressive dimming, although one owner found it held up better than a pricier rival.
Factory white balance is highly accurate in SDR; HDR has some minor gray-shade deviations.
White balance is remarkably precise from the factory and becomes even tighter with calibration.

Fast response and clean motion impress, but slow camera pans can still exhibit visible stutter.
Action and sports benefit from fast response and little trailing blur, making movement a clear strength.
Game Mode delivers extremely low delay, so control inputs feel immediate.
True Game responds almost instantly to controller inputs, giving fast gameplay a notably responsive feel.
Direct lights become diffuse and much less distracting thanks to the matte anti-reflective coating.
Direct light and sunlit windows remain difficult to overcome because the screen cannot get bright enough to compensate.
Four full-bandwidth HDMI 2.1 inputs leave enough connections for multiple current-generation consoles and a gaming PC.
Only two of the four HDMI inputs offer full gaming bandwidth; using eARC can leave just one free for a high-refresh device.
Vertical streaking in near-black scenes can be clearly distracting, despite relatively clean medium-gray areas.
Even difficult near-black shades look notably uniform, with only very faint banding.
This 77-inch RGB Tandem variant is noticeably more colorful than several other S90H sizes; results should not be generalized across the whole range.

Most gradients are clean, but low-light HDR scenes can develop visible posterization and shimmering.
Wide color-space coverage helps the panel retain saturation, including vibrant reds and greens.
Coverage is strong for standard cinematic colors, but the widest HDR color space exposes some limits in bright reds and greens.
Opinions differ on how loud the internal speakers can get: one test found limited output, another found it adequate for noisy rooms.
The onboard sound system gets unusually loud without adding much compression or audible strain.
Slow horizontal pans can jump visibly, and mild motion interpolation does not fully fix the problem.
Slow film pans can look especially choppy because the OLED pixels hold each frame so distinctly.
Very dark gradations can be crushed by imperfect gamma, offsetting otherwise strong shadow reproduction.
Subtle dark textures remain clear thanks to OLED contrast, though certain HDR settings can affect shadow luminance.
Tizen places advertising across its interface; targeted ads can be switched off, but ads as a whole cannot.
Fire TV home-screen ads cannot be completely disabled, an unwelcome distraction despite its otherwise smooth operation.
Small grooves in the stand offer a simple way to organize the cables behind the screen.
An integrated rear cable clip helps keep connections tidy, but the stand itself offers no equivalent routing.
Speech is easy to follow through the built-in speakers, even if voices can sound slightly thin.
The integrated audio system is described as delivering crisp speech without demanding an external speaker setup.
The screen avoids traditional PWM dimming but has small refresh-related brightness dips, so it is not absolutely flicker-free.
Most content looks free of distracting flicker, but sensitive viewers might notice slight fluctuations in darker areas.
Glossy-screen users may need time to adjust to the matte presentation, even though its glare reduction is superb.
The glossy finish helps the colorful picture look vivid, though it comes at the expense of handling direct reflections.
Internal speakers range from merely decent to remarkably good depending on the assessment, but dialogue remains intelligible.

The 77-inch model earns a highly favorable overall assessment for combining an improved OLED panel with outstanding reflection control.
The Z8BA is widely admired for its cinematic picture and powerful sound, with its value and bright-room fit more debated.
Optional black-frame insertion helps with 60Hz blur, but it is restricted to that rate and cannot eliminate persistence completely.
The optional black-frame-insertion feature can sharpen motion, but its unusual implementation raises questions about how much it changes the picture.
Static logos and persistent screen elements pose a real permanent burn-in risk, even though mixed viewing is less concerning.
Static images can cause permanent burn-in, so long-running news tickers or similar content require extra care.
Central-screen dirtiness is limited, though some darker vertical bands can still be seen across the panel.
Near-black surfaces are notably clean, with only subtle brightness variations or faint bands under scrutiny.
Film judder is removed reliably across most sources, with a small exception for some European-format signals.
Film judder is eliminated from almost every common source, with an unusual 25p/60p combination as the exception.

VRR operates smoothly over a broad frame-rate range, minimizing tearing with supported gaming hardware.
Gaming remains nearly tear-free even at lower frame rates when the source supports compensation.
Low-frame-rate compensation extends the smooth gaming effect into slower sections instead of allowing frequent tearing.
The broad panel-risk outlook is relatively reassuring, with important caveats for static content and eventual edge-pixel wear.
General hardware risk seems manageable, but long-term burn-in and possible edge-pixel deterioration deserve attention.
Dolby Vision is unavailable, ruling out that particular HDR format for compatible streams, discs and games.
Dolby Vision playback looks vibrant and polished, and its inclusion alongside HDR10+ broadens compatibility.
Dolby Vision is notably missing from an otherwise capable HDR display, potentially restricting preferred content formats.
Support for both Dolby Vision and HDR10+ is a meaningful strength for viewers using varied services and sources.
