Cube ACR Xiaomi: Complete setup instructions for the perfect image

Cube Technology ACR (Xiaomi’s Adaptive Color Range has become one of the key advantages of the brand’s modern TVs and projectors, promising richer colors, better detail in dark scenes and adaptive adjustment to the lighting in the room. It's too bright, it's too colorful, it's not natural, it doesn't work at all. ACR on Xiaomi devices – from basic parameters to hidden modes, which the manufacturer does not advertise.

It is important to understand that Cube ACR It works differently on TVs (Mi series) TV Q2, Xiaomi TV A Pro and projectors (Xiaomi Projector 2 Pro, Mi Smart Projector) will be used to look at both cases, focusing on the specifics of each device, and learn how to avoid common errors, such as why after activating the Cube ACR Shadows may disappear in movies or color artifacts may appear in games.

What's a Cube? ACR And how it works for Xiaomi.

Cube Technology ACR (Adaptive Color Range is a proprietary Xiaomi solution that dynamically adjusts the color range of the image depending on the size of the image:

🌞 Lighting in the room (brightness sensors analyze ambient light)
🎬 Content type (film, game, sports broadcast)
📺 Signal source (HDMI, embedded, USB)
🔍 Scenes on the screen (dark/light frames, contrast transitions)

Unlike the standard HDR, This only works with supported content, Cube ACR It tries to improve any image, even if the source is not optimized. SD-Video by Xiaomi Mi TV Q2 75' technology can artificially expand the color range by adding depth to black and saturation to red, but there's a major problem: Xiaomi's algorithms don't always do the job perfectly.

Projector Xiaomi Projector 2 Pro Cube ACR It works differently, by making up for the low brightness of the lamp by highlighting dark areas and smoothing out color transitions, especially in high-dynamic-range movies (like Marvel movies or Netflix originals) where no Cube is available. ACR shadows are lost.

⚠️ Note: On Xiaomi TVs 2020-2021 release (for example, Mi) TV 4S) Cube ACR It can be called an Adaptive Picture or AI Color Enhance is the same thing, but the algorithms are outdated. If your model is older, you better calibrate the image manually.

Preparing the device before setting up Cube ACR

Before activating the Cube ACR, You have to take a few critical steps, and if you skip them, you run the risk of getting a distorted picture or an unstable function:

Update your TV/projector firmware to the latest version

Reset the image settings to factory (Settings) → Picture → Reset)

Turn off all third-party image processing modes (e.g. Motion Smoothing or Noise Reduction)

Connect your device to a stable Wi-Fi network (to download Cube profiles) ACR)

Make sure that the source of the signal (prefix, media player) displays the image in the RGB 4:4:4 or YUV 4:2:2

Pay special attention to firmware updates: In versions older than 2.1.45 (for TVs) and 1.4.87 (for projectors) Cube ACR It works with bugs, for example, it can spontaneously turn off when you switch sources. → On TV. → POS version.

It is also recommended to calibrate the white balance manually before activating the Cube. ACR. For that:

Go to Settings. → Picture → Additionally. → White balance.
Select Warm or Neutral (avoid Cold – it conflicts with Cube algorithms) ACR).
Adjust the Red, Green and Blue sliders so that the grays look natural (use test images with gradients).

Cube step-by-step customization ACR on Xiaomi TVs

On Xiaomi TVs (series) Q2, A Pro, ES) path to Cube settings ACR This may vary depending on the software version. We will consider the universal method that works on most models of 2022-2026.

Step 1 Activation of Cube ACR

Open Settings → Picture → Image modes.
Select Dynamic or Movie profile (in these Cube modes) ACR work more efficiently).
Scroll down to Cube point ACR (or Adaptive Color and switch the switch to the on position..
In the window that appears, select Auto (for most scenarios) or Manual Setup (for advanced users).

Step 2: Optimization of parameters

If you have chosen Manual setting, the following sliders will be available to you:

Parameter	Recommended value	What does he answer for?
Brightness of adaptation	60–70%	The degree to which the lighting in the room is adjusted, and the high value leads to a soapy picture.
Color contrast	50–55%	It's a big difference between the shades%+ colours become unnatural.
Detailing shadows	40–60%	I'd rather put 40 percent on projectors, 60 percent on TVs.
Saturation	45–50%	Increases the intensity of colors. Exceeding 60 percent leads to a plastic effect.

Step 3: Verification of the result

After applying the settings, launch the test video (we recommend videos from the channel). RTINGS For calibration. Pay attention to the:

🔴 Skin tones – they should not be orange or green.
🌑 Dark scenes – details should be viewed, but without the gray veil".
🌈 Gradients – smooth transitions of colors (for example, sunset) should not be “sprayed".

💡

If you have switched on the Cube ACR The image is “soapy”, try to disable the Motion Clarity function in the Settings menu → Picture → In addition, these two technologies can conflict.

Specifics of Cube configuration ACR on Xiaomi projectors

Xiaomi Projector 2 Pro, Mi Smart Projector Cube ACR It has a different algorithm because it has to compensate for the low brightness of the lamp, and the key difference is that it prioritizes the detail of the shadows rather than extending the color range.

Step 1: Incorporation of the function

Go to Settings. → Display. → Image modes.
Select the Movie or Game profile (Bright Cube mode) ACR shutdown).
Activate the Cube ACR Set the Adaptation Level to Medium.

Step 2: Adjustment for different scenarios

Depending on the type of content, the following settings are recommended:

🎥 Movies: Detailing the Shadows = 70%, Saturation = 40% (to avoid "color noise" in dark scenes).
🎮 Games: Brightness of adaptation = 50%, Color Contrast = 60% (for better interface visibility).
📺 Sports broadcasts: Detailing shadows = 30%, Saturation = 55% (so that the grass field does not appear artificial).

Step 3: Removal of artifacts

On Xiaomi projectors when activating Cube ACR appear:

🔴 "Color spots in the corners of the screen – reduce saturation to 35%.
🌫️ "Nebula in light scenes – turn off Dynamic contrast in additional settings.
🖼️ "Blurring with fast movement – reduce the brightness of adaptation to 40%.

Why on Xiaomi Cube Projectors ACR It works worse than on TV?

The main problem is the limited brightness of the lamp (usually 500-800). ANSI Lumens. Cube algorithms. ACR They try to compensate for this by increasing contrast, but because of the low light output, this often leads to the loss of detail in light areas. TV Q2) There are no such problems, as the brightness can reach 1000 nits and above.

Common Problems and Their Solutions

Even after setting up the Cube correctly ACR Users are experiencing bugs, and these are the most common ones and how to fix them:

Problem 1: Cube ACR spontaneously shut down

Causes and solutions:

🔌 Unstable power: Connect the TV/projector to a network filter or UPS. ACR stress-sensitive.
📶 Weak Wi-Fi signal: The function loads cloud calibration profiles. If the speed is below 5 Mbps, it shuts down. Connect the device via Ethernet cable.
🔄 Conflict with other features: Disable Game Mode, Motion Smoothing, and Noise Reduction.

Problem 2: Colors look unnatural

This is a problem with miscalibration.

Reset Cube settings ACR factory (Settings) → Picture → Cube ACR → Reset).
Set saturation to 40-45% and gradually increase by watching the skin tones.
If the colors are still "curved", turn off the Cube ACR and manually calibrate the image according to the instructions RTINGS.

Problem 3: Incoming delays occur in games

Cube ACR Adds 10 to 15 milliseconds to the response time, to reduce lag:

🎮 Switch to Game Mode (Settings) → Picture → Image modes).
🔄 Turn off Dynamic Contrast and Local Dimming.
📊 Set the Brightness of Adaptation in Cube ACR at least 30%).

⚠️ Note: On Xiaomi TVs with a processor MT9611 (2020 models of the Cube ACR It can cause an image to twitch when watching a 24Hz video, in which case you have to choose between a smooth movie or an extended color range.

Advanced Settings: Hidden Cube Modes ACR
