Toshiba Fire TV 2020 Calibration Settings

For additional settings information, please consult the Common Problems and How to Calibrate pages.

We used the following calibration settings to review the 50" Toshiba Fire TV 2020 (50LF621U21), and we expect them to be valid for the 43" model (43LF621U21), and the 55" model (50LF621U21).

These settings should apply to most types of content, except for gaming or use as a PC monitor, which require a few additional changes, listed below.

General Settings


For SDR content, we recommend choosing the 'Movie' Picture Mode, as it is the most accurate one out of the box, and allows for the most customization. We recommend setting the Contrast to '75', Brightness to '0', Color to '-2', and Tint to '1', and Sharpness to '0', which is the no-sharpening setting.

You should adjust the Backlight to your viewing conditions. Note that this setting does not affect picture quality.

We left Dynamic Backlight and Dynamic Contrast disabled during testing. We also left MPEG Noise Reduction and Dynamic Noise Reduction turned off, but the can help reduce noise from some content. Note that these features can cause a loss of fine details in some scenes.


HDR is automatically enabled for the native apps. When you start playing HDR content, a small HDR icon appears in the picture settings menu. Once you start playing HDR content, some of the settings change automatically. We recommend choosing the 'Movie' Picture Mode, and leaving the other settings to their defaults in HDR.

For HDR to work from external devices, the HDMI Input Mode option usually has to be set to 'Mode 2 (2.0) for the input you are using. Older devices may have compatibility issues if this option is left enabled, so it is recommended to only enable this setting for devices that require it.

Dolby Vision

The Fire TV 2020 supports Dolby Vision, from native apps and with most external devices. As with normal HDR content, when you start playing Dolby Vision content, some settings change automatically. We recommend leaving these settings as-is; do not copy our SDR settings over.

How to Make HDR Brighter


If you find HDR content too dim, a brighter image can be obtained by setting Mid Luminance Gamma to '-5', and setting Dynamic Backlight and Dynamic Contrast to 'High'. Applying these three settings results in a brighter image, as shown by this EOTF.


From the base SDR and HDR settings, very few changes are required for a great gaming experience. When you start gaming, it is best to switch to the 'Game' Picture mode, to get the lowest input lag, and use the recommended settings for SDR or HDR.

For HDR gaming, it is important to make sure that HDMI Input Mode is set to 'Mode 2 (2.0)' for the input you are using.

PC Gaming

For PC Gaming, make sure you are using the 'PC' Picture Mode, and that HDMI Input Modeis set to 'Mode 2 (2.0)' for the input you are using.

For desktop PC use, PC mode is required in order to display text properly. When on the desktop, it is important to configure your computer to output in RGB; when sending YCbrCr 4:4:4, colors are not displayed properly and text isn't clear.

White Balance Settings

The following are the results of the white balance and colorspace calibration on our unit. They are provided for reference, and should not be copied as the calibration values vary per individual unit even for the same model and same size as the TV we reviewed due to manufacturing tolerances. If you want to try them you will need to enter all values shown, as all of them are active at the same time. If you end up with worse picture quality, simply reset them to the default values.
