This article contains answers to the most frequently asked questions about the limitations of Local Dimming.

General Information

Which Razer Blade Display has local dimming?

The Razer Blade 18” (2024), Razer Blade 16” (2024) and Razer Blade 16” (2023) mLED SKUs have local dimming.

What does Local Dimming do?

Local dimming maximizes contrast by increasing the intensity of bright and dark areas of the screen. This can sometimes strain your eyes and make the picture look odd at times. Consider disabling it and see if you like the picture quality with it turned off. It is likely to look more natural.

Can the local dimming on the Razer Blade be disabled or enabled?

Yes, but this feature is only available in the Razer Blade 18” (2024) and Razer Blade 16” (2024).

To enable or disable local dimming:

  1. Open Razer Synapse.
  2. Go to “SYSTEM” > “DISPLAY”.
  3. Click the checkbox under “LOCAL DIMMING”.

How many dimming zones does the display have?

The Razer Blade 18” (2024) has 2000 dimming zones, and the Razer Blade 16” (2024) and Razer Blade 16” (2023) have 1000 dimming zones.

What is Mini-LED?

Mini-LED refers to the backlight on an LCD panel. A standard LCD panel has a single zone behind the LCD substrate. A Mini-LED panel has a thousand miniature LED bulbs in the backlight behind the LCD panel. In combination, this allows for deeper blacks where the backlight is dim or off completely.

What are some of the limitations of local dimming?

Local dimming can slightly adjust the visuals on some monitors:

  1. Light blooming around bright objects.

    Due to the relatively large size of the backlight zones on most monitors, it is almost impossible to perfectly dim the backlight around a bright object on a black background.

    Blooming effects may occur because, in the case of the Blade 16 UHD display, one mini-LED zone covers an area of roughly 8 LCD pixels. The pixels are adjusted to account for this effect but some residual brightness may be visible in high contrast edges. For example, the mouse gets dim when on a black background.

  2. A loss of detail in dark areas.

    Similar to the issue with blooming, sometimes the opposite can occur. By dimming a dark scene too much, some small dim details can be lost. This issue is commonly known as black crush. Maybe use the example of the mouse on a black vs bright background.
