by Are you looking for best brightness settings to get better brightness, more impactful highlights, and deeper-looking blacks on your TCL Mini LED TV? Adjusting a few picture settings can help you tailor the image to your room, whether you watch television during the day or enjoy movies in a dark room at night.
In this guide, I’ll explain the TCL picture settings demonstrated in my HowISolve video, including brightness, contrast, gamma, local dimming, peak brightness, and dynamic contrast.
These settings are a practical starting point rather than a professional calibration. Your ideal values can differ depending on your TV model, firmware, viewing environment, and personal preference.
1. Open the Picture Settings Menu
Start by opening the Picture Settings menu on your TCL TV.
In the demonstration, I use Vivid picture mode. You can begin with Vivid if you prefer punchier-looking images, or use another picture mode if you prefer a less processed appearance.
The important point is to understand the settings below and test how they look on your own television.
2. Apply Picture Settings to All Sources
Navigate to Apply All Picture Mode and select All Sources, as shown in the video.
This option is intended to apply the selected picture configuration across supported sources. However, picture profiles can behave differently depending on the TV’s software, picture mode, and incoming video format.
After changing the settings, test ordinary SDR content, HDR10 content, and Dolby Vision content where supported. Open the picture menu during playback to verify which settings remain active in each format.
3. Set Brightness, Contrast, and Black Level
Start with these values:
| Picture setting | Recommended starting value |
|---|---|
| Brightness | 80 |
| Contrast | 50 |
| Black Level | 50 |
Brightness: 80
This is the brightness value demonstrated in the video. It can be a useful starting point if your picture appears too dim, particularly in a brighter room. If the image looks excessively bright in a dark room, reduce it to suit your environment.
Contrast: 50
Begin with 50, then assess bright highlights and detail in white areas. The goal is to retain visible detail rather than making every bright area look uniformly white.
Black Level: 50
Start at 50 and check dark scenes for shadow detail. Avoid lowering or raising the value simply to make the image look darker, because an unsuitable black-level setting can obscure shadow detail or make blacks look grey.
4. Choose the Right Gamma for Your Room
Gamma affects how brightness is distributed through the midtones and shadows of the image.
The video recommends two starting points:
- Gamma 2.2: A good starting point for normal viewing and well-lit rooms.
- Gamma 2.5: A setting to test during dark-room movie viewing.
If you choose gamma 2.5 for a dark room, you may also need to lower the brightness control to avoid an overly bright image.
Use the same movie scene to compare the results. Look at faces, dark clothing, shadow detail, and scenes with both bright highlights and dark backgrounds.
Your goal should be comfortable viewing with visible detail, not simply the darkest possible image.
5. Turn Automatic HDR Conversion Off
Set Automatic HDR Conversion to Off.
This follows the configuration demonstrated in the video. It avoids asking the TV to apply automatic SDR-to-HDR conversion to ordinary content through that setting.
Native HDR content is a separate matter: the actual playback format and the television’s active picture profile determine how that content is processed.
6. Disable Dynamic Contrast
Set Dynamic Contrast to Off.
Dynamic contrast adjusts the image dynamically, which some viewers may find distracting when brightness or contrast changes noticeably between scenes.
Starting with this processing disabled can make it easier to assess the picture and decide whether you prefer the TV’s own dynamic adjustments.
7. Set Local Dimming to Low
Set Local Dimming to Low as the starting value recommended in the video.
Local dimming controls the backlight zones behind the LCD panel. Its behaviour affects perceived contrast and how bright objects appear against dark backgrounds.
The ideal setting depends on the model and the content. Compare Low with the other available options using the same challenging scenes, and watch for any unwanted changes in shadow detail, blooming, or highlight intensity.
8. Adjust Peak Brightness
The video starts with Peak Brightness set to Low.
If the image still looks too dim for your room, try changing Peak Brightness to High, provided that option is available on your TV.
Compare both settings using the same material. A brighter image is not automatically a more accurate image, so choose the result that gives you comfortable viewing while preserving the detail you want.
9. Turn Local Contrast Off
Set Local Contrast to Off, following the demonstrated configuration.
Once this is done, check a scene with bright objects against a dark background, followed by a scene with several shades of grey. These scenes can reveal whether the picture looks balanced or whether some details appear unnaturally dark or bright.
Because processing controls can interact with each other, evaluate the complete picture rather than judging each setting in isolation.

Frequently Asked Questions
Are these the best settings for every TCL Mini LED TV?
No single set of values is ideal for every television, room, and viewer. Use these values as a starting point, then adjust them according to your model, room lighting, and the material you watch.
Should I use Vivid mode?
The demonstration uses Vivid mode, but it is not mandatory. Try your preferred picture mode and compare skin tones, highlights, shadows, and colour balance.
Should I use gamma 2.2 or 2.5?
Start with 2.2 for normal or well-lit viewing. Test 2.5 for dark-room movie viewing, and reduce brightness if the image is uncomfortable.
What should I do if my TCL TV still looks dim?
First check your room lighting, active picture mode, and source format. Then compare the Low and High Peak Brightness options if your TV provides them. Review the settings again while playing HDR or Dolby Vision content because its picture profile may differ from SDR.
Will these settings work after a firmware update?
They may be a useful starting point, but firmware updates can change picture processing, menu options, or the way picture profiles behave. Recheck the settings after an update instead of assuming every value is unchanged.
Final Thoughts
The settings demonstrated in this guide give you a starting point for balancing brightness, highlights, black levels, and local-dimming behaviour on a TCL Mini LED TV.
Try the configuration, watch a few familiar scenes, and make small adjustments according to your room. There is no need to sacrifice shadow detail or comfortable viewing simply to achieve the brightest possible picture.
