Start with Filmmaker, Movie, Professional or Expert mode; set the screen’s light output to match your room; enable local dimming; and treat HDR, movies and games as separate picture jobs. Leave contrast, black level and color near their preset values until you can check a test pattern. Do not copy white-balance numbers from another television.
The exact menu labels and the best local-dimming level vary by model, firmware and viewing conditions. Use the sequence below as a safe baseline, then make small changes while watching the material you actually use.
Use this setup order
Changing controls in a random order makes it difficult to tell which adjustment helped. Work through the television’s current input, update it, select an accurate preset, set overall light output, then handle contrast-enhancing and signal-specific features.
- Update the firmware and identify the exact model. Picture menus can change between model years and software versions. Check whether you are adjusting the internal streaming app, a game console, a disc player or a set-top box; each input can store a different profile.
- Select an accuracy-oriented preset. Choose Filmmaker Mode, Movie, Professional or Expert rather than Dynamic, Vivid or Standard.
- Set Backlight, Panel Brightness or Peak Luminance. This is the room-brightness control, not a substitute for black level.
- Leave Contrast, Brightness/Black Level and Color close to the preset. Use a calibration disc or test pattern before making large changes.
- Turn on local dimming. Begin with the model’s middle setting when one exists, and check both dark and bright scenes.
- Configure HDR separately. HDR can switch to its own picture mode and expose controls that are hidden for SDR.
- Set motion for your content. For films, start with interpolation off or low and use the dedicated film-judder control.
- Use Game Mode or Game Optimizer for consoles. Verify the HDMI format for HDR and 4K at 120 Hz.
- Only then consider white balance or a professional calibration. Those values are specific to an individual panel and room.
Choose the right picture preset
Filmmaker, Movie, Professional and Expert modes are designed to reduce the processing that makes showroom images look unusually bright or saturated. They generally start closer to the content creator’s intended grayscale, color and gamma. Dynamic or Vivid modes can be useful for a very bright shop floor, but they usually alter color, clipping and motion processing.

Samsung describes Filmmaker Mode as watching a movie or television show “without any changes to the picture settings.” Samsung also warns that this mode may look darker than other modes. That darker appearance is normally a consequence of removing enhancement, not evidence that the panel is defective. If the image is too dim in your room, raise the light-output control described in the next section instead of moving immediately to Dynamic mode.
Preset names are not standardized. A “Professional” mode on one brand is not guaranteed to match “Movie” on another, and some models expose separate presets for SDR, HDR10, Dolby Vision and games. Set the preferred preset independently for each signal type and input.
Match light output to the room
Look for Backlight, Panel Brightness, OLED Pixel Brightness (on sets that use that label) or Peak Luminance. On Samsung televisions, the support definition is straightforward: Backlight controls how much light the screen produces. Raise it in a bright room and lower it in a dark room.
Make this adjustment while watching normal content, not a white menu. In a dark room, excessive output can cause eye fatigue and make black bars appear gray by comparison. In daylight, too little output can make shadow detail disappear under reflections. Keep the control high enough that faces and subtitles remain readable, but not so high that ordinary SDR scenes look like HDR demonstrations.
Do not confuse this control with Brightness or Black Level. On many televisions, Brightness changes the digital level at which black begins; moving it too far can wash out blacks or crush near-black detail. Backlight or panel-brightness controls change the whole light budget while preserving the preset’s signal mapping.
Leave the core picture controls near their defaults first
Contrast, Brightness/Black Level, Color and Tint are interdependent. A large change to one can hide a problem created by another, so begin with the accuracy preset’s values.
- Contrast: Controls the upper end of the signal. Too high can clip bright clouds, white shirts and highlight texture; too low can make the picture flat.
- Brightness or Black Level: Controls the lower end. Raise it too far and blacks become gray; lower it too far and dark clothing merges into a single mass.
- Color: Controls saturation, not overall brightness. Increasing it to compensate for a dim image usually produces cartoonish faces.
- Tint or Hue: Leave centered unless a test pattern and a correctly filtered viewing method show a clear error.
- Sharpness: Keep it low enough that text and diagonal edges do not acquire white halos. A high value does not restore detail missing from a compressed source.
A calibration disc played through a Blu-ray player can provide clipping and black-level patterns. Samsung notes that calibration discs are available for purchase and can be used for this purpose. Streaming “calibration” videos can be altered by the app, player or television, so treat them as a rough check rather than a precision instrument.

Set local dimming for real mini-LED contrast
Mini-LED televisions divide the backlight into many independently controlled zones. Local dimming lowers zones behind dark areas and raises zones behind bright areas, which is why it is central to the technology’s contrast. The control may be called Local Dimming, Local Contrast, LED Local Dimming or a similar term.
Start with local dimming enabled. If the menu offers Low, Medium and High, Medium is a sensible first test because it balances black depth against pumping and blooming. Some televisions use Auto rather than numbered levels; in that case, Auto is the appropriate starting point.
Inspect three difficult scenes before choosing a final level:
- Dark subtitles on a black bar: Watch for a bright halo around each letter and for the whole bar lifting in brightness.
- Star fields or night scenes: Check whether stars disappear when a bright object moves, a behavior sometimes called black crush, or whether the backlight visibly pulses.
- Bright logos and saturated colors: Look for colored clouds or leakage beside white text and highly saturated objects.
More aggressive dimming can improve measured contrast but can also make zone transitions more visible. On the Sony BRAVIA 9 II, testing favored Auto Local Dimming at Medium with the Color backlight mode. The same testing found that High could create color leaking near saturated colors and white objects. That result is a model-specific observation, not a universal prescription for every mini-LED television.

If blacks look gray in a dark room and halos are acceptable, try one step higher. Recheck the setting for SDR and HDR because the television may store them separately.
Configure HDR as its own picture system
HDR10 and other HDR formats carry a wider brightness range than SDR. The television may automatically switch picture modes when an HDR signal arrives, and some controls can become unavailable or change names. Do not copy an SDR light-output number or tone-mapping choice into HDR and assume the result will be correct.
For HDR, first confirm that the source is actually sending HDR. On a console or player, inspect its video-information screen; on a television, look for the HDR indicator or the HDR-specific picture menu. If the source is outputting SDR, changing HDR controls will not affect the image you are watching.

Choose between accuracy and brighter highlights
HDR tone mapping decides how content mastered above the panel’s capability is fitted into the display. An accuracy or “gradation” option preserves the intended relationship between tones but may make the brightest highlights less conspicuous. A brightness-priority option raises visible highlights at the cost of departing from the reference curve.
Recommended Free Tools
On the Sony BRAVIA 9 II, testing preferred Gradation for accuracy, while Brightness produced stronger highlights. Use Gradation for films when preserving the mastering intent matters most; use Brightness only when you knowingly prefer a more forceful HDR presentation.
A documented HDR example
RTINGS’ LG QNED92A guide used Filmmaker Mode, maximum panel brightness and contrast, Dynamic Tone Mapping Off and LED Local Dimming Low for HDR10. Those are test-lab starting points for that model and signal, not universal mini-LED numbers. Your room, firmware and panel variance can justify different choices.
If HDR looks too dark, verify the source first, then check the television’s HDR tone-mapping option and its panel-brightness control. If highlights look blown out, reduce brightness-priority processing or return to the accuracy/gradation option before lowering contrast indiscriminately.
Preserve the film look with motion controls
Motion menus often separate de-judder from de-blur. De-judder processes low-frame-rate film material such as 24-frame-per-second movies; de-blur targets camera or object movement at higher frame rates. Interpolation can make pans smoother, but higher values can introduce halos, warped edges and the video-like “soap opera” appearance.
For movies, start with interpolation Off or Low. Keep the dedicated film mode or 24p handling enabled when available. LG’s Real Cinema option is designed to handle 24p judder; raising de-judder on top of it changes the film cadence and can add artifacts. If you dislike stutter on slow camera pans, increase de-judder one step at a time and inspect faces, fine patterns and subtitles for processing errors.
Sports and live television are more tolerant of interpolation because they are not mastered to a cinematic cadence. Even there, use the lowest value that removes the stutter you notice. Motion settings are preference-dependent, so there is no single “correct” number comparable to a black-level test.

Set up a console or PC input correctly
Enable Game Mode, Game Optimizer or the television’s equivalent for any input where controller latency matters. Samsung describes Game Mode as a speed-oriented setting; LG’s Game Optimizer groups gaming controls and status information in one place. Game modes reduce processing to lower latency, so the picture can look slightly less refined than in a cinema preset.
- Connect the console or PC to an HDMI port rated for the required bandwidth.
- Open the television’s external-device or HDMI settings and enable the enhanced format, often labeled HDMI Deep Color, Input Signal Plus or Enhanced Format.
- Turn on Game Mode or Game Optimizer for that input.
- In the console’s video menu, enable HDR and 4K at 120 Hz only if both the source and the television support them.
- Confirm that the console reports the expected resolution, refresh rate and HDR capability. If HDR is missing, return to the HDMI format setting before changing picture controls.
LG notes that HDMI Deep Color may be required for HDR or 4K/120Hz operation. Use the television’s on-screen information panel to verify the negotiated signal rather than relying only on the console’s checkbox.
Color temperature, white balance and calibration
Choose the preset’s neutral or warm color-temperature option if available; cinema-oriented modes commonly use a warmer white than showroom presets. Avoid judging white balance against a phone screen, because the phone’s own color profile and ambient light bias the comparison.
Two-point and multipoint white-balance controls change the red, green and blue mix at different brightness levels. They are not interchangeable between televisions, even when the model number is identical. Manufacturing variation means two units can require different values, and your room’s light can alter the most comfortable result.
RTINGS’ Sony BRAVIA 9 II and LG QNED92A guides explicitly describe their calibration values as starting points that should not be copied 1:1. Use published values only to understand which controls exist; do not enter them as a recipe. A colorimeter and software calibrated for the specific unit are needed for dependable numerical adjustment. If accuracy is critical for mastering, photography or professional review, a qualified calibrator can measure the set in its installed position.

Diagnose common problems without resetting everything
“Filmmaker Mode is too dark.”
Raise Backlight, Panel Brightness or Peak Luminance for the room. Check that an ambient-light sensor has not changed the output, and compare with a normal scene rather than a black test screen. Switching to Dynamic mode may hide the issue by altering the image, but it does not identify the cause.
“HDR is darker than SDR.”
Confirm that the source is sending HDR and that the television has entered its HDR picture mode. Check the HDR panel-brightness and tone-mapping controls. If Gradation preserves the intended curve but looks subdued to you, Brightness-priority tone mapping is a deliberate alternative, not a calibration error.
“Black bars or subtitles glow.”
Reduce local dimming one level and inspect the same scene. If the glow persists, compare Auto with the numbered modes and make sure a bright-room picture preset is not active. Some blooming is an unavoidable consequence of finite dimming-zone size, especially beside small bright objects.

Return Brightness/Black Level to the preset value, then recheck local dimming. Excessive dimming or a black-level setting that is too low can crush near-black detail. Use a near-black test pattern if available.
“The picture looks like live video.”
Lower de-judder or turn interpolation off. Keep Real Cinema or the equivalent 24p setting enabled for film sources. Increase processing only if you prefer its smoother appearance and have checked for halos.
“The console will not output HDR or 4K/120Hz.”
Use the television’s high-bandwidth HDMI port, enable its enhanced HDMI format or HDMI Deep Color option, and check the cable and console output settings. Game Mode affects latency; it does not by itself guarantee that the HDMI input is accepting the required signal.
When professional calibration is worthwhile
You do not need professional calibration to obtain a good picture from a new mini-LED TV. The accuracy preset, room-appropriate light output, sensible local dimming and correct HDR/game input settings solve most visible problems.
Calibration becomes more valuable when the television is used for color-critical work, when multiple viewers require a neutral reference, or when a particular unit shows a visible grayscale or color error after basic setup. Because white-balance values vary by unit and room, a calibrator should measure the installed television rather than apply numbers copied from a review.
