  1. 49-inch (49S425)
  2. 50-inch (50S425)
  3. 55-inch (55S425)

You must sort out these setting before you attempt to fix the others. For the best results, you should turn all the auto power saving options off. This will ensure that the TV doesn’t make adjustments to your images automatically.

SDR Settings

There are five different picture modes under SDR settings. You should choose “Movie” as it presents you with the best image quality. Beyond this, it gives you more opportunity to customize your image settings.

From here, you should move to the Advanced Picture Settings menu. Here you can adopt the following settings:

  1. Brightness – 50
  2. Contrast – 90
  3. Sharpness – 20
  4. Color – 45
  5. Tint (G/R) – 0
  6. Color temperature – Warm2

Along with these settings, you can turn off Gamma mode. If your images are not bright enough, you should consider adjusting the TV brightness. Visit the TV picture settings and choose any of the five preset options.

Following this, you should adjust your TV Backlight via the Advanced Picture Settings menu. Make your adjustments based on your current viewing conditions. It is important to note that altering these settings will not impact the overall picture quality. This is why we think you should leave out adjusting the brightness.

Image Enhancements

It is always best to see images in the closest quality to the creator’s intent. To achieve this, you need to disable Dynamic Contrast. If you are not satisfied with the results, then you should adjust the settings to suit your desires.

HDR Settings

For native apps, this feature is always enabled automatically. As soon as you begin to play HDR content, you’ll see a small HDR icon beside the picture mode. You can see this in the quick settings menu.

By default, some settings will change when you begin to play HDR content. One such setting is the Backlight setting. Here’s our recommendation. Leave these settings as they are when viewing HDR content.

Sometimes, you’ll need to load HDR content via external devices like HDMI 2.0. You’ll need to enable this from the input menu. Leaving this disabled may result in compatibility issues on older devices. This is why you should only make adjustments when the need arises.

For situations where the HDR content seems too dim, all you need to do is adjust Gamma. You can do this via the mobile app by increasing Gamma to 1.8. This will give you brighter images in HDR.

Motion Settings

There is no recommended setting when it comes to motion enhancement. Find what suits you best. For most people, they prefer to disable many of the functions under this menu. However, you should note that you may need to make a few adjustments depending on the content.

Judder Settings

There are no specific settings for this feature as well. By default, this TV will remove judder from all 24p sources. Examples of these sources include Blu-ray players and DVDs.


You can enter the game mode on this TV from any of the picture modes. To help you reduce input lag as much as possible, you should switch on Game Mode. In line with this, you can stick to the recommended settings for SDR or HDR content. Note that you need to enable HDMI 2.0 for HDR content.

TCL Advanced Picture Settings

For the more advanced users this guide walked you through pretty much any settings you need to calibrate your TCL TV and have the best results for every situation. However, advanced users might like to tweak their own settings and get a specific picture quality that suits them. 

If you are an advanced user and knows what each of the settings mean and do, please go ahead and tweak it to the best settings you see fit.
