How to set up a Xiaomi G24 monitor: a complete guide from connectivity to fine calibration

The Xiaomi G24 monitor is a popular solution for gamers, designers and office users thanks to the combination of 165 Hz, FreeSync Premium support and factory calibration at ΔE<1. However, even with such characteristics, many owners do not use the full potential of the device. This article will help you understand how to connect the monitor correctly, adjust color reproduction for different tasks and activate hidden functions that are not written in the standard instructions.

We'll look at not only the basic settings through the OSD- menu, but also the advanced tricks, from adjusting the gamma curve for design to optimizing input delay for eSports. And also why using a cable HDMI 2.0 at 165 Hz can miss a signal - and how to fix it without buying a new cable. If you want to squeeze the maximum out of Xiaomi G24, read on.

1. Monitor connection: choice of cable and connectors

The first step is to connect properly, and choosing a cable not only determines the maximum resolution, but also the refresh rate, HDR support, and even the input delay. The Xiaomi G24 features three basic interfaces:

• 🔌 DisplayPort 1.2 is the best choice for 165Hz and FreeSync. Supports G-Sync compatibility (if you have a video card NVIDIA).
• 🖥️ HDMI 2.0—limited 144 Hz at 1920×1080 resolution. 165 Hz will require manual reduction of color subsampling (4:2:2).
• ⚡ USB-C (only in the G24i model) – handy for laptops, but limited to 60Hz without additional adapters.

For gamers and professionals, DisplayPort is the only option that will unlock the full potential of the monitor. If you use HDMI, check the graphics driver settings: the NVIDIA or AMD control panel may have a "Limited Color Palette" mode that degrades the image quality. To fix this, go to the NVIDIA Control Panel → Display → Change resolution → Output Dynamic Range and select "Full".

⚠️ Warning: When connected via HDMI at 165Hz, the monitor may periodically lose signal, due to a limited cable bandwidth, Solution: reduce the frequency to 144Hz or use a certified DisplayPort 1.2 cable with support for DSC (Display Stream Compression).

2 Basic settings via OSD-

The control buttons on the Xiaomi G24 are located on the bottom bezel on the right. To open the menu, press the first button (with the gear icon). The OSD interface is intuitive, but some points need to be explained:

• 🎨 Picture Mode: Standard - a balance of brightness and contrast for office work; gaming - increased brightness and saturation, but can distort colors; cinema - optimized for watching movies (low brightness, warm hue); Custom - for manual adjustment (recommended for design).
• 🔄 FreeSync — only turn on if your graphics card supports the technology. NVIDIA requires you to activate G-Sync in the control panel.
• 🕒 Sleep Timer is useful for saving energy if you often forget to turn off your monitor.

The most common user error is to use pre-modes (Game or Movie) without additional calibration. These profiles often overstate saturation and gamut, which leads to unrealistic colors. For accurate work, it is better to start with User Mode and calibrate the monitor using programs like DisplayCAL or built-in tools Windows/macOS.

Turn off Dynamic Contrast (Distorts Colors)

Set brightness to 80-100 (depending on lighting)

Select the color temperature of 6500K (neutral white)

Activate FreeSync if you are using AMD/NVIDIA-->

3. Color calibration for design and photography

The factory calibration of the Xiaomi G24 provides ΔE<1, but for professional work (retouch, 3D- modeling, printing) requires fine tuning. Here is the step-by-step process:

1. Reset to factory settings: Go to OSD → System → Reset to exclude the impact of previous changes.
2. Select Color Space: In the OSD menu, go to Color → Color Mode and select sRGB (for web design) or Adobe RGB (for printing).
3. Calibration with colorimeter: Connect a device like the X-Rite i1Display Pro and use DisplayCAL software to create a ICC- profile. If you don't have a colorimeter, use online services like the Lagom LCD Test to visually adjust the gamut and gray gradations.

Pay special attention to the following parameters:

• 📊 Gamma: The optimal value is 2.2 (standard for Windows). MacOS may require 1.8.
• 🎛️ Contrast: Set on 50-60 (the factory value 70 often overstates the black level).
• 🔍 Sharp: By default 50, but for text you can zoom in to 60-70 (no higher, otherwise artifacts will appear).

⚠️ Warning: If the colors look dim after you calibrate, check if Windows is activated with Night Light or HDR mode. These functions override the monitor settings. Turn them off to Settings → System → Display.

4.Optimization for games: frequency, input delay and Overdrive

For gamers, the key parameters are refresh rate, input delay and Overdrive technology.

Frequency of update:

• In Windows: Settings → System → Display → Additional Display Settings → Adapter Properties → Select 165Hz.
• In games: In graphics settings, set the FPS limit to 1-2 frames below the maximum monitor frequency (e.g. 163 FPS for 165 Hz) to avoid tirring.

Delayed input:

According to RTINGS.com, the Xiaomi G24 has a ~4ms input delay in Overdrive: Extreme mode. However, this mode can cause inverse ghosting on dark backgrounds.

• 🎮 For shooters (CS2, Valorant): Overdrive: High + AMA: High (in driver AMD/NVIDIA).
• 🏎️ For racing simulators: Overdrive: Medium (less artifacts when moving fast).

3. FreeSync/G-Sync:

To activate adaptive synchronization:

1. Turn on FreeSync in the OSD- monitor menu (System → FreeSync → On).
2. For NVIDIA: In the control panel, enable G-Sync compatibility for full-screen and window modes.
3. For AMD: Activate Enhanced Sync in Radeon Settings → Display.

💡

If you see a flicker in games when FreeSync is on, try limiting the frequency range in the driver settings, for example, setting the minimum FPS to 48 instead of 30.

5. Customization of sound and additional functions

Although the Xiaomi G24 is not positioned as a multimedia monitor, it is equipped with two speakers of 3 watts. For basic sound, this is enough, but for high-quality playback it is better to connect external speakers or headphones through a 3.5 mm jack on the rear panel.

Among the hidden functions:

• 🔇 Super Resolution mode (in the Sound menu) - mimics surround sound but can distort low frequencies.
• 📡 Bluetooth connection (only in the G24i model) – allows the monitor to be used as a wireless speaker.
• 🖼️ PiP/PbP - Picture-in-Picture mode for simultaneous display of two sources (e.g. PC + console) Activated in System → PiP/PbP.

To connect the headphones:

1. Insert the plug into the Audio Out connector on the back.
2. In OSD-, select Sound → Sound Source → 3.5 mm.
3. Adjust the volume with buttons on the monitor or through software (e.g. Equalizer APO for Windows).

⚠️ Warning: When using DisplayPort, no audio is transmitted — you need HDMI or a separate audio connection. If there is no audio, check if the correct source is selected in the Windows settings (Control Panel → Sound).

6. Removing common problems

Even with the right settings, Xiaomi G24 users sometimes run into problems, and here are the most common solutions:

If the monitor suddenly began to "glutch" (artifacts, spontaneous switching modes), perform a hardware reset:

1. Turn off the monitor.
2. Press the Menu button (second from the right) and, holding it, turn on the power.
3. Hold the button for 10-15 seconds until the Xiaomi logo appears.

💡

If image problems have occurred after updating the graphics card drivers, try rolling back to the previous version. Often, FreeSync or high-frequency bugs are fixed in the following patches.

7. firmware update and hidden features

Xiaomi periodically releases firmware updates for its monitors, fixing bugs and adding new features.

1. Download the latest firmware version from the official website (section "Monitores → G24").
2. Unpack the archive and copy the.bin file to a flash drive formatted in FAT32.
3. Turn off the monitor, insert the flash drive into the USB port (for service) on the back.
4. Press the Menu button and turn on the power. Hold the button until the update process begins (about 3-5 minutes).

After the update, new options may appear, for example:

• 🎯 Low Blue Light Pro mode is an improved blue light filtering with intensity setting.
• 🖥️ Automatic source switching – the monitor itself determines the active input (DisplayPort/HDMI).
• 🔧 Advanced Overdrive Settings are separate profiles for different genres of games.

⚠️ Warning: Don't take the flash drive out or turn off the monitor during the upgrade! If the process is interrupted, the monitor may stop turning on, in which case you will need to contact the service center to flash through the SPI- port.
