Compare TCL RM9L vs Samsung 77S90H OLED

The best scenes look spectacularly bright, colorful, and three-dimensional. Some lower-quality content, color errors, and inconsistent processing stop the performance from being uniformly excellent.

Deep blacks, natural color and rich highlights give this 77-inch screen an excellent overall image.

The factory picture can be too cool, with blue-heavy grayscale and HDR midtones brighter than intended. Accurate reproduction needs a carefully chosen preset or calibration.

Natural color reproduction is a highlight, while HDR white balance and near-black gamma are less perfect.

Deep bass is a repeated limitation, and built-in low-frequency weight trails the scale of the screen. An external subwoofer helps.

Bass sounds deep and full, although the lowest notes could be more precisely defined.

Low-bitrate streaming artifacts are handled effectively, with a small sacrifice in fine texture at heavier smoothing levels.

Compression problems such as posterization and macroblocking are not removed particularly well.

Color is beautifully saturated, but accuracy assessments vary by picture preset. Factory blues can be too cool, while Filmmaker Mode and calibration give much better balance.

Natural skin tones and very small SDR color errors make the picture convincing before extensive adjustment.

RGB Mini LED delivers unusually pure, bright color, making its benefits obvious with vivid source material. Color bleeding and a thicker backlight structure remain compromises.

The 77-inch model's RGB Tandem OLED structure delivers a real improvement over several other sizes in the series.

Enormous peak luminance is one of the TV's defining advantages, making bright highlights and daytime scenes exceptionally punchy.

Peak light output is strong, particularly for small highlights, but the C6H and premium G6/S95H alternatives can surpass it.

The factory white balance can lean blue, though other presets and professional calibration improve it substantially.

Factory white balance is highly accurate in SDR; HDR has some minor gray-shade deviations.

A large number of effective dimming zones preserves intense highlights without washing out adjacent blacks. Very bright settings can still create visible halos.

Individually lit pixels mimic ideal local dimming without the compromises of backlight zones.

Extremely bright highlights and vivid daylight scenes give HDR films tremendous impact. Long sustained highlights, however, can dim over time.

Small highlights look striking, although sustained bright scenes and higher-end rivals expose some brightness limits.

Built-in audio divides opinion: it can sound clear and balanced for everyday television, yet lacks the punch and refinement expected beside such a large picture.

Built-in sound draws mixed assessments: balanced and clear but quiet in one evaluation, exceptionally rich in another.

Dark-room movies benefit from very deep blacks and intense pinpoints of light. Viewers sensitive to blooming may need to lower peak-brightness settings.

Near-perfect blacks make movies look dramatic in dark rooms, although vertical near-black bands prevent a flawless result.

High-quality footage reveals remarkable textures, from animal hair to intricate movie effects. Compressed feeds sometimes expose softness or blotchy artifacts instead.

Subtle picture textures survive well even with ordinary streaming and cable feeds.

Picture settings have an unusually large effect on the result: good choices reveal beautiful images, while aggressive defaults can skew color or create artifacts.

Fine-tuning a good picture for both daylight and evening can require more work than expected.

Games look brilliant, expansive, and responsive on this screen. Slight trailing and the occasional picture-mode quirk keep it short of flawless.

Very low lag, fast pixels and broadly effective VRR make this an especially capable gaming TV.

Bright HDR material can be strikingly vivid and immersive, with strong blacks and saturated color. Tracking inaccuracies and mode inconsistencies limit its faithfulness to the source.

HDR material looks vivid and contrasty, with strong highlights and rich colors, though large bright fields are less commanding.

Sunlit rooms are no match for the RM9L's enormous brightness reserve. Some direct reflections remain visible despite the panel's anti-glare treatment.

Bright daylight and nearby windows do little to spoil visibility, especially in scenes that would otherwise reflect the room.

The strong native panel contrast and precise backlight create excellent separation between deep shadows and bright highlights.

Pixel-level black control creates outstanding contrast, and the matte coating helps preserve that advantage in light-filled rooms.

Peak highlights are spectacular, but brightness falls noticeably if those bright elements remain on screen for a sustained period.

OLED brightness falls when much of the picture is bright, reducing impact in sunlit scenes or full-screen white imagery.

Sports and gaming generally look smooth and controlled, with better performance than older models. Some sources still show blur or uneven cadence.

Fast response and clean motion impress, but slow camera pans can still exhibit visible stutter.

Controls generally feel responsive, especially at high refresh rates. Sixty-hertz lag is somewhat less competitive but still satisfactory for everyday gaming.

Game Mode delivers extremely low delay, so control inputs feel immediate.

The LCD panel avoids permanent OLED-style burn-in, helping ease concerns about static interfaces and long gaming sessions.

Static logos and persistent screen elements pose a real permanent burn-in risk, even though mixed viewing is less concerning.

Gentle smoothing improves camera pans, but stronger settings can make films look artificially processed.

Gentle interpolation settings do little to erase stutter in slow pans, limiting their value for film watching.

Low levels of interpolation reduce the hold-time stutter that can appear in slow panning shots.

Slow horizontal pans can jump visibly, and mild motion interpolation does not fully fix the problem.

Near-black scenes are impressively even, while large gray or bright areas show some darker edges and modest uniformity issues.

Vertical streaking in near-black scenes can be clearly distracting, despite relatively clean medium-gray areas.

The screen reduces indirect glare reasonably well but can still show mirror-like reflections and rainbow artifacts from bright light sources.

The matte finish dramatically suppresses mirror-like reflections, a decisive advantage over many glossy OLED alternatives.

The internal speakers cannot get especially loud, limiting how well their sound fills a large entertainment room.

Opinions differ on how loud the internal speakers can get: one test found limited output, another found it adequate for noisy rooms.

Full chroma support and an RGB subpixel layout keep desktop text well defined, making occasional PC display use practical.

A revised subpixel pattern helps text somewhat, but Windows ClearType is not optimized for it.

Motion response is generally respectable, but transitions between dark and bright shades can be slow enough to create light trails.

Almost instantaneous pixel changes sharply reduce the blur behind moving objects.

Local dimming usually keeps halos modest, particularly head-on, but increasing brightness makes blooming more visible. Fully suppressing halos costs substantial light output.

Bright highlights sit against black backgrounds without the halos that can appear on backlit TVs.

Compressed streams lose much of their blockiness, though aggressive cleanup can soften tiny details and make textures seem waxy.

DVD and lower-quality video remain surprisingly detailed after scaling, though visible compression artifacts can persist.

Immense light output does much of the work against room glare. Direct reflections and some diffraction effects still show up under challenging lighting.

Direct lights become diffuse and much less distracting thanks to the matte anti-reflective coating.

Most gradients look smooth, but one assessment found serious banding in certain Dolby Vision scenes. Changing to Dolby Vision Dark can resolve that specific issue.

Vertical bands in very dark scenes are an unwelcome weak point, even though ordinary gradients are generally smoother.

Side-viewing performance is contentious, ranging from impressively steady at moderate angles to obvious color and brightness shifts farther off-axis.

Side seats retain excellent contrast and generally stable colors, with only mild color shifting.

The RM9L earns enthusiasm for extraordinary color, brightness, and immersive gaming, but its price and inconsistent picture behavior prevent universal endorsement.

The 77-inch model earns a highly favorable overall assessment for combining an improved OLED panel with outstanding reflection control.

Most color transitions are smooth with only minor, barely noticeable steps outside the problematic Dolby Vision examples.

Most color transitions are subtle and smooth, but very dark gray gradients can exhibit banding.

Games and action scenes remain fairly sharp, although darker pixel transitions sometimes leave mild blur trails behind fast objects.

Fast-moving objects appear sharp with almost no smearing across 60Hz, 120Hz and 165Hz operation.

Strong contrast can reveal excellent dark-scene texture, though some factory modes crush shadows and need adjustment.

Very dark gradations can be crushed by imperfect gamma, offsetting otherwise strong shadow reproduction.

Near-black pictures look clean with almost no visible banding or backlight bleed. Mild clouding is present when local dimming is disabled.

Fully black areas are exceptionally even and remain free of halos, despite separate issues with near-black gray tones.

Rear cable guides and a stand notch help route multiple connections without leaving an untidy trail.

Small grooves in the stand offer a simple way to organize the cables behind the screen.

Careful calibration can transform color accuracy into one of the TV's strengths. The process is awkward because menus and local dimming interfere with measurements.

SDR is easy to dial in with excellent results; HDR calibration yields little further improvement.

Speech can sound clean and suitably full, although uneven speaker response sometimes makes dialogue less consistent.

Speech is easy to follow through the built-in speakers, even if voices can sound slightly thin.

The center of the screen stays relatively clean during sports, but darker edges can be distracting on large, uniform fields.

Central-screen dirtiness is limited, though some darker vertical bands can still be seen across the panel.

Backlight zone transitions track moving objects smoothly with little visible flicker or instability.

The screen avoids traditional PWM dimming but has small refresh-related brightness dips, so it is not absolutely flicker-free.

Small sparks, bright reflections, and camera flashes pop sharply against darker scenes. Only the most extreme peaks occasionally lose subtle shading.

Bright details are usually preserved impressively, although one assessment noted some loss at the very brightest levels.

The combination of 4K/144Hz inputs and even faster lower-resolution modes makes high-frame-rate gaming flexible and enjoyable.

Fast OLED transitions make rapid action crisp at high frame rates, ideal for smooth competitive play.

The two blade-style feet look neat and support the large panel effectively, although they offer no narrow mounting position.

The pedestal feels supportive and lifts the image usefully above a cabinet.

The wide feet keep the massive display surprisingly steady, with minimal wobble.

Its pedestal holds the very large panel securely without obvious wobble concerns.

Low-frame-rate compensation helps maintain tear-free play even when games drop well below their target frame rates.

Gaming remains nearly tear-free even at lower frame rates when the source supports compensation.

Compatible consoles automatically trigger the low-lag gaming settings, avoiding manual switching each time a game starts.

Automatic Game Mode switching removes the hassle of manually selecting the lowest-lag settings on modern consoles.

Deep blacks remain convincing beside small bright objects, often approaching OLED-like depth. Extreme peak-brightness settings can lift black levels.

OLED's self-lit pixels produce genuinely inky blacks that give dark scenes impressive depth.

The RGB backlight covers an exceptionally broad range of color, producing vivid reds, greens, and fine variations that standard televisions struggle to match.

Wide color-space coverage helps the panel retain saturation, including vibrant reds and greens.

Brilliant colors retain impressive intensity as brightness rises. Some white-adjacent colors and saturated scenes reveal the technology's limits.

The 77-inch RGB Tandem panel delivers unusually vivid colors for this range, staying rich even when brighter colors fill the screen.

High-definition and lower-resolution sources upscale to a clean, detailed image, making even older shows convincing at 85 inches.

Standard-definition and HD sources look cleaner and smoother after conversion to the native 4K display.

VRR works smoothly across compatible sources and helps avoid tearing even through sharp frame-rate drops.

VRR works extremely well across the panel's range, preventing most visible tearing.

Automatic game detection and intuitive settings reduce friction, although the most accurate HDR Game Mode can look dimmer than other modes.

Entering Game Mode preserves peak brightness while unlocking exceptionally responsive gameplay.

Upscaling and optional detail enhancement can improve ordinary material, but automatic adjustments sometimes produce inconsistent colors between inputs and presets.

Fine detail is preserved, but compression artifacts are not cleaned up as effectively as on some competing OLEDs.

Google TV continues showing ads even when personalization is disabled. Avoiding them requires a basic setup that sacrifices many smart functions.

Tizen places advertising across its interface; targeted ads can be switched off, but ads as a whole cannot.

Four full-featured HDMI 2.1 ports remove a common flagship-TV compromise, making it easy to connect several high-end gaming devices.

Four full-bandwidth HDMI 2.1 inputs leave enough connections for multiple current-generation consoles and a gaming PC.

Four well-equipped HDMI inputs provide ample room for a console, gaming PC, sound system, and additional streaming devices.

Four high-bandwidth connections allow a multi-device setup without sacrificing full-speed ports.

Movies play with very little judder across most sources, though unusual frame-rate combinations can show small timing issues.

Film judder is removed reliably across most sources, with a small exception for some European-format signals.

Panel risk factors appear favorable in theory, yet an actual dead-zone failure and changing image output raise legitimate concerns.

The broad panel-risk outlook is relatively reassuring, with important caveats for static content and eventual edge-pixel wear.

The range of supported HDR formats is broad enough to avoid choosing a TV around one preferred HDR standard.

Dolby Vision is notably missing from an otherwise capable HDR display, potentially restricting preferred content formats.

Broad variable-refresh support helps reduce screen tearing and works with low-frame-rate compensation for smoother games.

Supported FreeSync sources can run with very little tearing, including when frame rates dip.

Dolby Vision is available, but some Dolby Vision picture modes have produced troublesome banding. Dark mode can be a safer choice than brighter presets.

Dolby Vision is unavailable, ruling out that particular HDR format for compatible streams, discs and games.

PlayStation 5 and Xbox Series consoles can use their full 4K/120Hz output with responsive motion and VRR support.

The 77-inch set accommodates demanding current-generation console signals, making fast 4K play a genuine strength.

Modern HDMI features are available across every input, including high-refresh 4K signals and the gaming modes buyers expect.

Full 48Gbps bandwidth across all four ports offers generous flexibility for demanding gaming signals.

HDR midtones and bright scenes can be pushed far above the intended brightness. Calibration and more restrained picture settings matter for accurate reproduction.

HDR luminance tracking is impressively faithful, retaining detail through most mastered brightness ranges.

HDR midtones and bright scenes are often pushed too high, so the picture looks more intense than the mastered signal intended.

Static tone mapping favors accuracy, while Active makes scenes brighter at the cost of faithful reproduction.

The Google TV ecosystem covers a very wide range of services, including major catch-up and subscription streaming apps.

Tizen has a broad catalog of streaming apps and games, making it easy to find major services.

Personalized ad targeting can be disabled, but ordinary Google TV ads remain unless smart functions are restricted.

Disabling personalized advertising is possible, but completely removing promotional material from the interface is not.

The slim-bezel, dark-metal presentation looks upscale from the front, but the thicker rear body is less graceful from the side or on a wall.

The slim body and minimal framing give this 77-inch television an elegant, upscale appearance.

Very slim side borders help the display seem almost frameless. The thicker lower edge and somewhat bulky back are easier to notice from certain angles.

Thin screen borders and a slender profile help this enormous OLED blend into a refined living-room setup.

The fine border keeps the emphasis on the picture and makes the large display feel cleaner and more immersive.

Narrow bezels help the large panel look clean and contemporary rather than bulky.

The set feels solid and premium overall, with reassuring stand stability. The rear panel is less rigid than the rest of the construction.

The extremely thin chassis feels well assembled and shows no obvious workmanship problems.

Every HDMI port handles 4K at 144Hz, giving high-refresh PCs and consoles flexible connection options without needing a special input.

Streaming from an iPhone worked smoothly, with reliable playback and no observed control glitches.

No DTS support is disappointing for disc collectors whose Blu-rays use DTS soundtracks.

The eARC connection handles high-quality uncompressed audio to compatible external receivers or soundbars.

Attaching the feet is straightforward, but the huge, heavy panel is awkward to lift, position, or bring through narrow doors.

The visual quality is impressive, yet flagship pricing makes standard Mini LED and OLED alternatives hard to ignore. Value improves only for buyers who specifically want this RGB technology and scale.

Automatic picture adjustment can leave the TV looking different after a source or mode change. An occasional incorrect transition makes the result difficult to trust.

Optional black-frame insertion helps with 60Hz blur, but it is restricted to that rate and cannot eliminate persistence completely.

Built-in speakers deliver surprisingly substantial low-end weight, tempered by some muddiness.

Bright saturated objects can tint neighboring white or pale areas, especially in demanding scenes. It is barely noticeable in some viewing, yet a recurring flaw at high brightness.

Compatible PC hardware can benefit from smooth variable-refresh output over a broad range.

Low-latency motion smoothing can make older low-frame-rate games look less choppy without a severe control penalty.

Samsung's low-lag smoothing option helps lower-frame-rate console games without substantially compromising responsiveness.

The Game Bar is easy to reach and provides useful signal readouts, frame-rate information, and practical adjustments during play.

Older and lower-quality sources are enlarged smoothly to 4K, with little jagged edging or loss of fine texture.

The 85-inch panel makes movie characters, racing environments, and game landscapes feel almost life-size. Its scale can also overwhelm a modest room.

With no backlight zones to coordinate, bright-to-dark transitions avoid local-dimming pumping or halos.

OLED pixel transitions are exceptionally clean, with only slight overshoot around certain dark-to-bright changes.

This 77-inch RGB Tandem variant is noticeably more colorful than several other S90H sizes; results should not be generalized across the whole range.

Moving or positioning the exceptionally large panel is difficult and may require multiple people and an oversized route into the room.

Up to 165Hz delivers particularly sharp, fluid gaming motion when the source supports it.

The backlit metal-look remote feels premium, with convenient programmable and picture-adjustment buttons.

Backlighting, a programmable shortcut, and direct picture controls are convenient. Some button placements and the brightness rocker direction are less intuitive.

Useful shortcuts speed up picture changes, but the off-center Home key and reversed brightness rocker may take getting used to.

Glossy-screen users may need time to adjust to the matte presentation, even though its glare reduction is superb.

Internal speakers range from merely decent to remarkably good depending on the assessment, but dialogue remains intelligible.

The far-apart feet require a very wide TV unit. They offer stable support but little flexibility for smaller furniture.

Four full-bandwidth HDMI inputs offer plenty of flexibility for a gaming PC, consoles and other high-demand video gear.

Wall mounting is possible, but the thicker rear profile looks less sleek than TCL's slimmer SQD flagship.

Wireless satellite and subwoofer support provide a practical way to build bigger audio than the built-in speakers can deliver.

Artwork can look impressive at this size, with automatic dimming in screensaver mode. The glossy panel and fixed bezels do not replicate a dedicated art television.

Major surround formats can pass to a compatible receiver or soundbar, making the TV easy to fit into a more serious audio setup.

Simple controls let users shift between brighter, warmer, and more energetic sound profiles without mastering an equalizer.

Switching sources or picture modes can produce different colors and light output despite returning to the same calibrated preset. This unpredictability is especially frustrating at flagship pricing.

The pedestal leaves useful room beneath the picture for a soundbar.

Despite side- and rear-mounted speakers, the sound spreads convincingly across the width of the screen.

Navigation is snappy, with Google TV responding quickly to directional inputs.

Google TV feels fast and responsive when opening menus and moving through the interface.

Google TV brings a familiar layout, user profiles, and plentiful content options. Advertising remains a nuisance unless the set is configured with fewer smart functions.
