Compare LG B6 vs Samsung S90H

Picture quality is consistently strong, with rich color, deep blacks, crisp detail, and an attractive OLED presentation. A green tint on one test unit keeps it from being uniformly excellent.

Picture quality is a major strength, with deep OLED contrast, rich color and crisp detail repeatedly standing out. The matte screen and some default modes can soften or exaggerate the image, but the core panel performance remains highly regarded.

The soundstage is narrow and rarely extends beyond the screen.

Amplify mode opens the presentation noticeably, creating a wider and more involving soundstage than the default setting.

Built-in sound is serviceable for everyday viewing but clearly trails the picture. Reviewers recommend a soundbar for fuller, more cinematic audio.

Built-in sound is better than expected for such a slim OLED, especially in Amplify mode. It still cannot match a dedicated soundbar for scale and low-end weight.

Daytime performance is usable thanks to improved brightness, especially in Standard or Vivid mode. Strong overhead lighting can still expose the reflective screen.

Bright-room performance is unusually strong for OLED because reflections are suppressed and brightness remains useful even with windows or overhead lights present.

Color accuracy is mixed. One reviewer measured better accuracy than the C6, while another saw a noticeable green tint compared with the B5.

Color can look highly natural and accurate in the better picture modes, especially Filmmaker Mode. Standard and AI-heavy modes can push skin tones or whites too cool or warm.

Bass is limited and thin, with only modest rumble during effects-heavy scenes.

Bass has some useful weight, but deep low frequencies remain limited and a soundbar adds substantially more impact.

The OLED panel is a major strength, delivering self-emissive contrast and image quality that reviewers consider superior to similarly priced LCD and QLED alternatives.

OLED remains central to the S90H’s appeal, delivering self-emissive blacks, strong contrast and fast gaming response. The move away from QD-OLED in some sizes is the main tradeoff.

Fullscreen brightness improves only modestly and can vary by picture mode. Small highlights benefit more than sustained bright scenes.

Full-screen brightness falls as OLED protection engages, but the sustained result is still described as competitive for the class.

HDR has satisfying impact, with punchy highlights and rich color. It cannot match the brighter C6, but it remains convincing for this price tier.

HDR is consistently praised for impactful highlights, deep blacks and rich color. The strongest results come from better picture modes rather than the most aggressive defaults.

Dark-room viewing is excellent, where the OLED blacks, contrast, and Filmmaker Mode presentation look their best.

In evening and dark-room viewing, the OLED panel delivers the deep blacks, contrast and depth that home-cinema buyers expect.

Peak brightness is clearly improved over the B5, but opinions depend on context. It is brighter than prior budget OLEDs yet still noticeably dimmer than the C6 and other premium sets.

Peak brightness is strong for a midrange OLED and gives HDR highlights real impact, though results vary by size and it remains below Samsung’s flagship models.

Fine textures and skin tones look natural and refined. The presentation favors realism over the exaggerated brightness of some higher-end models.

Accuracy is strongest in Filmmaker-style settings, where skin tones, grayscale and source intent look convincing. More aggressive presets can trade that fidelity for extra brightness and punch.

OLED contrast is a standout, with bright highlights and dark tones balancing cleanly in demanding scenes.

OLED contrast is a standout, pairing near-perfect blacks with bright highlights for a deep, dimensional image in movies and games.

HDR brightness rises meaningfully over the B5 and reaches roughly 695–895 nits depending on mode and test method. Premium competitors remain much brighter.

HDR brightness is strong enough to make highlights pop and handle lit rooms well, though it trails the S95H and can vary by screen size.

Gaming performance is one of the TV’s clearest strengths, combining excellent picture quality, smooth movement, and highly responsive controls.

Gaming performance is a standout, combining 165Hz support, VRR, low lag and excellent OLED contrast across consoles and PCs.

Fast sports and action are handled smoothly, with minimal artifacts and confident control during rapid gameplay.

Motion is strong once settings are dialed in, with clean fast action and few artifacts. Default or automatic smoothing can be less natural.

Input lag is superb, measured around 8.9ms at 4K 60Hz in boost mode, with no noticeable delay during play.

Input lag around the 9ms range at 4K/60Hz is repeatedly described as exceptionally responsive for gaming.

Glare resistance is a weakness under strong room lighting, with reflections remaining visible even during brighter content.

The matte Glare Free coating is one of the S90H’s defining strengths, dramatically reducing glare. The tradeoff is slightly raised blacks or reduced perceived crispness in some conditions.

Colors look bold, deep, and highly vibrant, with animation and HDR material producing especially strong pop.

WOLED versions lose some high-brightness color intensity compared with QD-OLED, most noticeably in demanding wide-gamut HDR material.

AI search is genuinely helpful for finding settings and answers inside the TV’s user guide.

Search is uneven: AI-enhanced search can find content, but the lack of a straightforward app-store search can make simple tasks frustrating.

The widely spaced legs occupy more media-console space than the C6’s central stand.

Closely spaced feet make the S90H easier to place on narrower furniture than many large OLED rivals.

The thin panel mounts neatly on a wall and looks especially clean in that configuration.

The thin panel looks wall-mount friendly, but the thicker rear electronics section can leave a visible gap at the edges.

LG’s motion interpolation works well when used selectively, reducing film judder without needing the strongest settings.

Interpolation is useful when kept moderate, but stronger or automatic settings can introduce obvious soap-opera effect and unnatural motion.

Reflection handling drew conflicting impressions. One reviewer found the screen highly mirror-like under lab lights, while another thought it remained quite good in a harsh showroom.

Reflection control is exceptional: direct and indirect light is heavily diffused, making the screen unusually usable in bright rooms.

Stand stability is disputed: one reviewer found the feet sturdy enough, while another lacked confidence around active pets.

Once installed, the feet hold the TV securely and provide a stable base.

Shadow detail is well preserved, allowing texture and subtle information to remain visible inside very dark scenes.

Shadow detail is the main dark-scene weakness: some presets bury information near black, although picture controls can recover part of it.

Judder reduction is effective for both movies and sports, with different presets suiting each type of content.

Judder can show up at default settings, but modest custom adjustments clear it up without forcing an overly smoothed look.

Lower-resolution video receives a useful boost in texture and color, but it does not approach true 4K detail.

Older and lower-resolution sources hold up surprisingly well, with processing that preserves texture while avoiding heavy-handed cleanup.

The dual-foot stand is the weakest part of the physical design, feeling cheaper and less reassuring than a central pedestal.

The stand is functional and can be sturdy once assembled, but its plastic cover, feel and assembly quality draw mixed reactions.

Dialogue is generally clear and easy to follow. The speech enhancement mode can help difficult mixes, though it degrades other frequencies.

Dialogue stays clear and naturally placed in most scenes, with voice-enhancement processing available when room noise competes.

Color gamut coverage is still good, but one measured result was unexpectedly lower than the B5.

The S90H covers mainstream DCI-P3 material very well, but WOLED samples show narrower BT.2020 coverage and less extreme color punch than QD-OLED alternatives.

HD and SDR material is sharpened effectively, producing crisper textures and stronger perceived contrast.

Upscaling is one of the S90H’s clearest strengths, making HD and even DVD material look cleaner and more detailed without excessive artificial sharpening.

Image processing is useful overall, especially automatic picture adjustments, but aggressive sharpening can look artificial.

Samsung’s processor is capable and often excellent at detail, upscaling and cleanup, but some AI modes can over-brighten or cool the image and are better disabled for accuracy.

The remote layout has avoidable annoyances, including missing dedicated input and mute buttons, though the customizable favorite button provides workarounds.

The compact layout omits useful dedicated controls such as an input button, pushing more actions into onscreen menus.

Picture and audio customization is flexible, and LG’s guided options make it easy to choose a preferred presentation.

Phone-assisted Smart Calibration is convenient for quick tuning, though it is not a substitute for a full professional calibration.

Personalized recommendations may become useful over time, but one reviewer did not test them long enough to judge their full value.

Personalized suggestions can work surprisingly well after some use, although recommendation features are not central to the TV’s appeal.

The rear-firing speakers lose some volume and detail against the wall, reducing impact at louder levels.

The speakers can lose composure when pushed hard, so demanding scenes at high volume expose the limits of the slim chassis.

The gaming dashboard provides useful extra controls, including settings aimed at minimizing input delay.

Samsung’s Game Bar is particularly useful, putting refresh, HDR, genre and aiming controls within quick reach during play.

The Magic Remote is capable and customizable, but opinions vary on its pointer and premium feel.

The solar/USB-C remote is light and convenient, but minimalist controls are not universally loved.

Motion stays clear and fluid, with little visible blur in games and smooth frame delivery in sports.

Fast gaming and sports motion stays clear, helped by OLED response and high refresh rates.

Four HDMI inputs provide ample connectivity, and reviewers considered the overall port selection sufficient for most setups.

Four HDMI inputs give the S90H enough wired flexibility for multiple consoles, players and audio gear.

Black levels are outstanding, staying deep even in lit rooms while preserving visible detail within dark areas.

Black levels are excellent in dark rooms and create the depth expected from OLED. Strong ambient light can lift blacks slightly because of the matte anti-glare treatment.

The native 120Hz panel keeps fast sports and games smooth, and reviewers achieved stable high-frame-rate playback.

The 165Hz ceiling is a major gaming upgrade for capable PCs and is repeatedly praised as a premium feature.

Game Optimizer is highly effective, reducing lag, improving frame-rate handling, and keeping controls smooth.

Game Mode stays highly responsive and preserves strong picture quality, making it suitable for competitive and cinematic games alike.

Account setup can be frustrating; app-assisted Google login failed for one reviewer and required manual completion.

Using built-in streaming apps requires a Samsung account, and the associated permissions/setup flow can feel intrusive or tedious.

Advertising remains intrusive, including a large home-screen banner and ad-heavy LG apps.

Ad behavior is inconsistent across impressions: one interface showed no top banner, while others criticized Samsung TV Plus autoplay and persistent promotional content.

Nvidia G-SYNC compatibility is included alongside FreeSync, making the TV well suited to PC and console gaming.
