Compare Hisense U7SG vs TCL Q77K

The screen gives vivid color, crisp detail and a bright image for the money, but uniformity and the accuracy of some presets vary.

Everyday 4K material can look crisp and colorful for the price, but rigorous testing finds obvious weaknesses in brightness, contrast and HDR.

Highlights and bright HDR scenes have serious punch, giving the U7SG an advantage over many similarly priced screens.

HDR highlights fail to stand out against surrounding scenes, and overall brightness is too low to create dramatic impact.

The dimming system gives dark scenes strong contrast and mostly controlled glow, with occasional odd highlighting or flicker.

There is no zone-by-zone backlight control, so dark areas stay brightened and highlights lack the contrast of Mini LED competitors.

Colorful, high-impact HDR is a highlight of the set, but some presets require correction for their cooler color or tone-mapping behavior.

HDR format compatibility is broad, but contrast, color volume and brightness are too limited to make HDR particularly convincing.

The panel delivers exceptional peak brightness for the price, keeping HDR highlights vivid and maintaining visibility in daylight.

Both HDR highlights and regular SDR scenes are relatively dim, limiting impact and daytime versatility.

Some listeners hear fuller, surprisingly punchy bass, while others find the deepest rumbles weak or the default boost overpowering.

The speakers lack genuine low-end weight and rumble, leaving music and action effects thin.

Height channels add spaciousness, but the integrated system cannot match the width of separate speakers.

The built-in presentation is narrow and thin rather than immersive, particularly with demanding film soundtracks.

Built-in sound often surprises with spaciousness and punch, but assessments vary on dialogue balance and deep bass.

Built-in audio handles casual dialogue but lacks rich bass, spaciousness and consistent loudness across sizes.

High native contrast and local dimming add depth, although OLEDs and some pricier Mini-LED alternatives are stronger in challenging darkness.

Native contrast is acceptable for the price, yet the lack of local dimming makes dark scenes visibly weaker than better TVs.

Filmmaker Mode can look impressively faithful, but HDR white balance and default brightness curves need care for reference results.

Calibration can bring white balance and gamma very close to target, although some saturated blues remain slightly off.

Compatible receivers and soundbars can receive high-quality audio using eARC and support for major surround formats.

Major audio formats pass through from connected external sources, although the same behavior is not guaranteed for every built-in app.

Low-quality video gets useful compression cleanup, but added image enhancements sometimes introduce unwanted grain.

Compressed videos receive useful smoothing, although finer details may look softened or waxy.

Dark scenes can look impressively deep for LCD, but raised blacks, residual blooming and shadow-processing quirks keep OLED ahead.

Dark rooms expose raised blacks and limited HDR punch; it works for casual viewing but disappoints for cinematic contrast.

SDR white balance is generally good, while uncalibrated HDR can look noticeably cool until adjusted.

The initial cool cast and gray inaccuracies are notable, but careful calibration can bring tones much closer to neutral.

SDR looks bright and colorful, although Filmmaker and PC/Game presets favor different aspects of accuracy.

Standard content is watchable and sometimes pleasantly colorful, especially when reflections and ambient light are managed.

Well-mastered 4K footage reveals convincing textures and fine detail, especially in brighter HDR scenes.

Native 4K scenes look crisp with excellent fine detail; upscaled text and other tiny details are less dependable.

Theater, Filmmaker and Dolby Vision IQ each offer useful alternatives, and turning off certain defaults can substantially improve realism.

Changing brightness and color-temperature settings can improve dark or flat-looking content significantly.

The pedestal offers height options that can make room for an external soundbar without blocking the screen.

The stand leaves around 3.6 inches beneath the screen, enough space for most soundbars without blocking the picture.

An impressive gaming feature list and very low lag coexist with middling motion sharpness for fast-moving objects.

Gaming is the clearest strength thanks to rapid inputs, VRR and high-refresh modes, though fast pixels and dark-game contrast are weaker.

SDR color and skin tones can be remarkably natural, but uncalibrated HDR or different presets may introduce green or blue tints.

Opinions diverge: fine flesh tones and detail can look natural, but uncalibrated color and white balance may be cool or inaccurate.

Real-world sports can look fluid, but slow pixel transitions, film judder and occasional artifacts mean motion is not consistently premium.

Assessments vary, but detailed testing finds conspicuous 60Hz blur even as some evaluations praise ordinary motion.

Controller actions appear rapidly across supported modes, making this one of the set's clearest gaming strengths.

Very low input delay makes the Q77K feel responsive in supported console and PC modes.

The matte screen suppresses direct sunlight and bright lamps better than many similarly priced TVs; larger glossy variants differ.

Glossy models visibly mirror lamps and windows. Matte finishes on the two largest sizes improve reflections but cannot add brightness.

Small bright objects and sunlight often retain clear separation, with occasional dimming of the tiniest specular highlights.

Bright details can be lost or appear too dim, making HDR objects look flat rather than luminous.

Direct reflections are strongly reduced by the matte surface, and indirect ambient glare is mostly kept in check.

Reflections are intrusive on glossy variants, whereas the 85- and 98-inch matte coatings make placement easier near bright lights.

Channels in the pedestal help hide cords, but some find the routing limited outside the stand itself.

There is no integrated cable-routing system, so wires need to be organized separately.

Bright highlights retain richly saturated colors, with little washout in strong light.

The Q77K struggles to maintain saturated HDR colors, particularly darker tones, despite acceptable color presentation in standard content.

Fast-frequency backlight PWM is hard to see normally, although transitions and VRR flicker may trouble sensitive viewers.

Low-brightness settings use low-frequency backlight modulation that may bother sensitive viewers and cause visible image duplication.

The Mini-LED backlight usually produces deep blacks, but some dark-room comparisons reveal raised shadows and residual halos.

Without local dimming, blacks look gray or washed out in darker scenes even though the native panel contrast is serviceable.

Subtle HDR gradients sometimes break into visible steps, particularly darker greens and grays.

Shaded gradients look mostly smooth, with relatively little obvious banding, although the darker end is less polished.

Google's show-first home page can be useful for discovery but offers limited control over the promoted rows.

Google TV collects shows and suggestions from several services in one home screen, helping reduce app hopping.

High frequencies retain good definition without as much harshness as cheaper television speakers.

High notes lack detail and contribute to a bright, closed-in sound presentation.

Compressed streams and older HD material get cleaner edges and reduced macroblocking without excessive over-sharpening.

Compressed streams and old video remain watchable, though noise cleanup trades away some fine texture.

Dark scenes tend to look clean, but bright uniform backgrounds may expose vignetting or dirty-screen patches depending on the panel.

The tested panel had noticeable uneven gray shading and a pinch mark, so checking a new unit for patches is worthwhile.

Four full-bandwidth HDMI inputs on the common sizes provide unusual flexibility for consoles, PCs and soundbars; the biggest model is an exception.

The tested 75-inch unit has two full-speed gaming ports rather than four; other sizes may differ, so several high-bandwidth devices require planning.

Sports and some games can look crisp, yet laboratory testing and several owners note blur during dark transitions.

The high refresh-rate specification masks mediocre pixel transitions, especially in dark areas and ordinary 60Hz footage.

The panel covers most of DCI-P3 with vivid results, but it cannot reproduce every shade of the wider BT.2020 gamut.

Cartoons and everyday SDR scenes can look lively, but the limited HDR color range prevents deeply saturated highlights from looking rich.

The backlit tactile keys are helpful at night, but shortcut placement and missing direct playback controls bother some users.

Backlit buttons and a simple layout make the remote comfortable to operate in the dark.

Careful calibration can yield excellent accuracy, although the absence of a familiar automatic calibration option is disappointing.

Calibration is straightforward and can improve white balance and overall color accuracy dramatically.

The broad adaptive-refresh window is useful at high frame rates, but 60Hz handshakes and certain VRR transitions can be problematic.

Supported high-bandwidth HDMI inputs cover a broad VRR range, reducing tearing when frame rates dip; the 60Hz ports are less capable.

Side-mounted, labeled ports are straightforward to find and connect once the TV is on its stand.

Rear inputs are generally workable but can be awkward to reach once the television is close to a wall.

Dark HDR skies and gradients may show banding, with unusual artifacts sometimes visible in greens.

Color and brightness transitions are mostly smooth, though darker gradients can reveal some banding.

Older HD and lower-bitrate sources receive sharper detail with minimal artificial edge enhancement.

HD and some lower-resolution material upscale clearly, yet very fine text and textures can become soft.

Low-frame-rate films can stutter on slow pans, but a little interpolation makes motion easier to watch.

Motion interpolation reduces stutter effectively on slow pans when enabled, with little variation in timing.

Most bright highlights are well contained, although small subtitles and starfields can reveal halos.

Bright subtitles do not create the usual local-dimming halos, but this advantage comes at the expense of deep blacks and strong highlights.

Dark backgrounds generally look even, with little backlight bleed, though sample variation can affect the edges.

Near-black scenes remain fairly even without obvious vertical bands, though some patchiness and warm spots occur.

Game Mode keeps HDR brightness strong and latency low, though it cannot eliminate the screen's slower response times.

Game Mode keeps controls responsive, but it cannot fix flat HDR and blurry pixel transitions in every scene.

A compact central footprint can fit narrower media units than widely spaced feet.

Two foot positions on the 75-inch model provide narrower or wider furniture options, a welcome flexibility for a large TV.

Some tests found clean sports fields, while others exposed blotchy patches and darker screen edges on uniform backgrounds.

The tested 75-inch panel showed uneven patches and a pinch mark that could stand out on grass, ice or other broad flat colors.

Large promoted banners and personalized recommendations consume much of the Google TV home screen; switching off personalized ads does not remove them.

Google TV includes ads and recommendations that cannot be fully switched off, a drawback for people wanting an uncluttered home screen.

Common sources play without major judder, while some 24p material or 25p sources can require motion tweaks.

24fps movies play without distracting cadence judder, and 1080i film broadcasts also receive strong frame-rate treatment.

The backlit remote and brushed finish are practical, although the large utilitarian shape looks dated to some people.

The simple voice remote is functional and pleasant to use, with backlighting an unexpectedly helpful extra.

Free ad-supported channels add extra viewing choices, including some worthwhile older programming.

TCL’s built-in live TV section loads fairly quickly and expands the selection of no-extra-cost viewing.

Color ghosting, soft edges and distracting transition trails may appear in rapid action despite the high refresh specification.

Slow dark transitions and variable-refresh overdrive can cause colored trails, overshoot and blurred moving edges.

Full chroma support helps desktop detail, yet the BGR subpixel layout can cause text fringing on a PC.

The BGR subpixel arrangement can make fine desktop text look less crisp than on a conventional RGB monitor.

VRR is useful over a broad gaming range, but 60Hz handshakes and certain frame-rate changes can produce flicker or incompatibility.

Wide VRR format and range compatibility keep games nearly tear-free as frame rates fluctuate, especially on the full-speed inputs.

Speech is generally clear on the integrated speakers, but one comparison found voices harder to hear against effects and music.

Speech is intelligible at normal volume, making news, sitcoms and casual TV easy to follow without external speakers.

Many dark scenes retain fine texture, although some modes flatten shadows or raise near-black detail.

Results are mixed: gentle tonal gradations can be reproduced well, yet some near-black areas appear crushed before calibration.

Pixel transitions are slower than the refresh-rate label suggests, leaving dark smearing and blur in fast scenes.

Pixel response is mixed: high-refresh gaming feels responsive, but dark transitions and 60Hz scenes can be noticeably blurry.

The redesigned metal pedestal is solid and stylish, with a heavier feel than previous plastic stands.

Adjustable stand positions and sturdy feet are practical strengths, although construction varies and the overall set is budget-oriented.

Color and contrast can fade rapidly as viewers move away from the center, especially on the tested VA panel.

Colors shift and fade toward the sides; it remains usable for some side seats but looks best head-on.

The 165Hz native 4K mode and faster reduced-resolution options favor capable PCs, but response-time blur limits ultimate competitive clarity.

Fast PC modes are outstanding value at up to 4K/144Hz or 1080p/288Hz on supported sizes, despite slower 60Hz pixel response.

Adding light smoothing helps slow pans and 24p stutter, although aggressive settings can change the cinematic look.

Interpolation can smooth camera pans effectively, but some find motion processing artificial or blurry and prefer it off.

The game overlay supplies frame-rate, HDR and crosshair tools, but reaching the panel can take more remote presses than ideal.

A capable game bar provides frame-rate readouts, aiming tools and quick access to VRR, picture modes and latency settings.

Head-on viewing is strongest, with off-center colors and contrast fading more than ideal for large family seating.

Off-center viewing is acceptable for a VA-style set, but saturation and image depth fade noticeably at steeper angles.

The set handles 1440p/120Hz game signals and can run at even higher frame rates at reduced resolution with suitable PCs.

Both PlayStation 5 and Xbox gaming support 1440p at 120Hz, providing flexibility between image resolution and speed.

Games can trigger the lowest-lag mode automatically rather than requiring manual switching.

Automatic Game Mode removes the need to hunt through settings before gaming, keeping input lag low.

The LCD panel is effectively immune to permanent OLED-style image burn-in, a useful advantage for long-term static-content use.

As a direct-lit LCD, the screen carries little risk of permanent burn-in from static game HUDs or channel logos.

Up to 165Hz at 4K is excellent for a midrange television, even though frame transitions are not always as fast as the refresh number implies.

A native 144Hz panel is exceptional for this price range, though faster input support does not guarantee blur-free motion.

As an LCD, the TV avoids permanent burn-in and several common panel risks, but the newest generation lacks long-term owner history.

Expected longevity is decent rather than outstanding, with low burn-in risk offset by more vulnerable direct-lit backlight failure behavior.

High-bandwidth connections extend to all four standard-size HDMI inputs, avoiding the typical compromise of only one or two gaming-ready ports.

Two HDMI inputs on the tested 75-inch unit handle modern 4K high-refresh signals, unlike the two limited 60Hz ports.

A discounted 75-, 85- or 100-inch model can deliver substantial screen space for the cost, though premium extra-large sizes rise sharply in price.

The 75-, 85- and 98-inch models provide substantial screen size for the money, with gaming support rarely found this cheaply.

The eARC port makes high-quality audio transfer to a soundbar or AV receiver straightforward.

An eARC connection makes it easy to pair a soundbar or receiver and pass compatible surround audio from external devices.

When discounted, the U7SG combines standout daylight viewing and connectivity for far less than many flagship models; full price is less persuasive.

The low Costco pricing buys unusually advanced gaming features and large screen options, but picture weaknesses make a cheap Mini LED upgrade worth comparing.

PS5 and Xbox consoles can use 4K at 120Hz without giving up their usual VRR options.

Modern consoles can reach 4K at 120Hz on the high-bandwidth ports, with VRR and automatic Game Mode available.

AMD FreeSync Premium Pro adds a valuable adaptive-refresh option for compatible gaming equipment.

FreeSync Premium Pro helps Xbox and compatible gaming hardware deliver smoother play as frame rates vary.

Thin bezels keep the picture visually prominent and give the set a clean, modern appearance.

Bezels look slim at a glance, but the visible gap between the frame and first pixels reduces the premium effect.

Smaller and larger variants differ in peak output, coating, stand and sometimes connections, so specifications should be checked for the precise screen size.

The 85- and 98-inch variants have reflection-friendly matte screens, while smaller models are glossy; refresh ceilings and port arrangements can vary too.

A thin frame and substantial industrial-style center pedestal make this look more expensive than an ordinary budget screen.

The slim exterior is appealing for a budget television, although materials and frame details are less refined than premium models.

The sturdy metal stand and improved finish feel substantial for the price, even though the cabinet remains midrange rather than luxury-grade.

Construction is adequate for the price but plastic-heavy. Metal feet are appreciated on the smaller showcased unit, while another sample showed a panel pinch mark.

A hardware microphone mute and software toggles offer control, though tracking and promotions may be enabled by default.

A physical microphone switch can fully disable the TV’s hands-free mic for added reassurance.

Core brightness tracking can be close to the intended curve, while optional dynamic tone mapping sometimes produces a strange, overprocessed image.

Tone tracking is surprisingly faithful for moderately bright HDR scenes, with a smooth highlight roll-off, yet hardware limits cap the final effect.

Google Home and Android integration is useful for linked devices, photos and household smart-home controls.

Voice assistant, casting and compatible smart-home controls add everyday convenience beyond streaming.

On-TV streaming generally runs smoothly, although the newer phone setup app can struggle to connect during onboarding.

Everyday streaming is simple, but advanced picture settings, forced updates and signup prompts can complicate the first experience.

Google setup brings account prompts and legal agreements, which can slow down first use.

Automatic picture switching is handy for viewers who would rather let the TV choose between movies, sports, and games.

Missing ATSC 3.0 support limits over-the-air broadcasts to older standards rather than next-generation broadcasts.

A varied selection of decorative seasonal and ambient art gives the display an entertaining second purpose.

The black-frame insertion option is compromised by image duplication and a pronounced loss of brightness.

The live TV interface includes a useful program guide showing current broadcasts.

The upward-firing speakers can add welcome width and height, but separate surround speakers still create a larger sound field.

Four HDMI connections offer good basic connectivity, although not all can carry the highest refresh-rate signals.

Low-bitrate cleanup and upscaling are strong, although certain default settings can make highlights or motion look unnatural.

A full set of standard accessories is packed with the TV, although the box location can initially be confusing.

The very large versions offer imposing cinematic scale, and the strong brightness keeps that extra screen area lively.

The zones generally follow movement well, but highlights can visibly flicker while moving across the screen.

Loudness varies by size and source: the 55-inch test struggled in larger spaces, while the 65-inch unit and one video evaluation sounded adequate.

A bright, feature-packed Mini-LED set makes a convincing mainstream choice, with motion performance and dark-room precision its main compromises.

Lift-off packaging can make unboxing safer and easier, although one demonstration used special shipping protection not supplied to retail buyers.

A conventional removable two-prong cord is a welcome practical touch.

Spaced tactile keys are easy to locate, but the missing play/pause shortcut and awkward tuner key slow certain actions.

The largest matte-screen variants reduce mirror-like reflections substantially compared with the glossy smaller sizes.

The metal pedestal is secure once assembled; some find the screws straightforward, while others recommend an extra pair of hands.

The heavy center base gives the TV reassuring resistance to wobble.

The available app storage is adequate for everyday streaming, although heavy app users may want more space.

A rich input selection handles multiple consoles and external audio equipment without demanding constant cable swaps.

Common VESA mounting options are available, although spacing, port access and handling become important with the biggest models.

Two high-bandwidth ports on the tested 75-inch set enable 4K/144Hz, making high-frame-rate PC play a major attraction.

4K console games benefit from bold HDR, low lag, and up to 120Hz support, though some motion smears on rapid transitions.

The 55-inch model can reach 240Hz at 1080p, offering a fast mode for PC gamers who prioritize frame rate over resolution.

Larger specified sizes can accept 1080p at 288Hz on supported inputs, an exceptional option at this price tier.

Dolby Vision and HDR10+ cover both major premium HDR ecosystems, so format compatibility is rarely a concern.

Google TV onboarding can be fast, but the heavy stand, app-pairing failures and unskippable updates may slow a new owner's setup.

The Costco bundle’s advertised five years of combined coverage and return window strengthen the value proposition, but the extra years are a protection plan, not manufacturer warranty.

T-Exhibition brings attractive looping 4K artwork to the screen, although some selections take a while to load.

A useful EQ, sound modes, dialogue boosts and subwoofer controls offer lots of flexibility, but intelligent settings can complicate manual adjustments.

Ambient-light adaptation can gently adjust the screen for changing room conditions without repeated manual changes.

The matte treatment and strong light output overcome typical windows and room lights with little glare distraction.

Aiming overlays, shadow controls and a visible FPS counter give gamers quick, practical tools during play.

Fine for ordinary SDR viewing in a controlled room but too dim to overcome direct sunlight or bright lamps.

Full-screen bright content dims compared with smaller HDR highlights, something most visible in white-heavy sports.

A generous selection of picture modes allows different looks for films, sports, games and Dolby Vision content.

HDR tracking is mostly good, while optional dynamic mapping can brighten scenes or make movement look unnatural.

Gemini handles ordinary questions but sometimes points to the wrong service or stops at a show's information page.

The 55-inch variant tops out at 1080p/240Hz, while listed larger models can reach 288Hz; specifications should be checked by size.

A broad selection extends well beyond 85 inches, but brightness, coating and stand designs are not identical across sizes.
