Toshiba C350 Series 2023 Calibration Settings

We used the following calibration settings to review the 65-inch Toshiba C350 Series 2023 (65C350LU), and we expect them to be valid for the 43-inch (43C350LU), 50-inch (50C350LU), and 55-inch (55C350LU) models. 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.

These settings are meant to provide a starting point; they're not meant to be copied 1:1. They provide the most accurate image overall, but you should adjust them to match your preferences and viewing conditions.

One of the first things we did was disable all of the extra image processing features, as we didn't want the TV to adjust the image during testing. We disabled 4:3 Stretch and disabled any automatic power savings settings in the Display and Sounds section.

For SDR content, you can choose a few different preset picture modes. We used the 'Film' Picture Mode because it's the most accurate out of the box and allows for the most customization.

We set the Contrast to '83', Brightness to '0', Color to '0', and Tint to '0', 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.

In Advanced Settings, we left Dynamic Backlight, Dynamic Contrast, and Local Contrast Enhancement disabled during testing. We left Mid-Luminance Gamma to '0', as that's closest to our calibration target. We also left MPEG Noise Reduction turned off, but it can help reduce noise from some content. Note that these features can cause a loss of fine details in some scenes. We also left Super Resolution 'Off' for calibration. Note that our recommended sharpness settings for upscaling are different than our calibration settings. For upscaling, we recommend setting Sharpness to '5' and Super Resolution to 'On'. 

HDR is automatically enabled for the native apps. A small HDR icon appears in the picture settings menu when you start playing HDR content. Once you start playing HDR content, some settings change automatically, including Backlight, which increases to 'Max.' We left all the picture settings at their defaults in HDR, except for Contrast, which we set to '90', and Color Temperature, which we set to 'Warm1', but you should adjust them to whatever looks best.  In HDR, the 'Film' Picture Mode delivers the most accurate image, as it best tracks the PQ EOTF. This ensures that most content is displayed at the brightness level the content creator intended.

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.

The following are the results of calibrating the white balance of our unit to 6500K in HDR. They are provided for reference and shouldn't be copied as the calibration values vary per individual unit, even for the same model and size as the TV we tested, due to manufacturing tolerances. If you want to try them, you'll 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.

The Toshiba C350 Series 2023 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.

Unfortunately, there aren't any additional motion settings like black frame insertion, motion interpolation, or judder removal on the Toshiba C350 Series 2023.

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. You can also enable the Game Mode (Auto Low Latency Mode) setting that automatically switches the TV in Game Mode when you launch a game from a compatible device.

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.

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

The Toshiba C350 Series 2023 supports eARC, allowing you to pass high-quality audio to a compatible receiver through an HDMI connection. For it to work, set ARC Mode to 'eARC' with the Digital Audio Format to either 'Passthrough' or 'Auto'. These settings are found in the Display & Audio section.

The Toshiba C350 Series 2023 has a few accessibility features, and the settings are all available in the Accessibility section. You can enable Captions, High Contrast Text, and Text to Speech, to name a few.
