How to set up the Xiaomi Mi Surface Display 34 monitor: from basic parameters to professional calibration

The ultra-wide Xiaomi Mi Surface Display 34, with a 3440×1440 resolution and a curved 1500R screen, has become one of the most popular monitors for work, creativity and gaming in the brand’s lineup. However, even with factory settings, it rarely reveals its potential 100%. A misguided color profile can distort shades when editing photos, and a suboptimal refresh rate can spoil the game experience. This article will help avoid typical mistakes and customize the monitor for specific tasks, from office work to eSports battles.

We will analyze not only the basic parameters like brightness and contrast, but also the hidden menu functions. OSD, PC connection features/Mac, And also professional calibration with hardware calibrators, and we'll focus on a common problem, which is flickering when you're in the middle of a calibration. 100 Hz, improper scaling in Windows and artifacts when using FreeSync. All recommendations are based on tests with the latest drivers AMD/NVIDIA (2026 year) and monitor firmware V1.0.12.

1. Preparation for setting up: what to do before turning on the monitor

Before diving into the settings menu, make sure the monitor is connected correctly. Xiaomi Mi Surface Display 34 supports DisplayPort 1.4 and HDMI 2.0, but their features are very different:

• 🔌 DisplayPort is the only connector that allows you to use the maximum resolution 3440×1440 upon 100 Hz with FreeSync Premium support, perfect for gamers and professionals.
• 📺 HDMI 2.0 — permission-bound 2560×1440 upon 60 Hz. Suitable for office tasks or connecting to a laptop without DP.
• ⚡ USB-C — transmits video (do) 3440×1440@60Hz) + charge the laptop (up to) 65W), It requires a compatible cable (not included in the package!).

Use certified cables — cheap analogues may not support the desired bandwidth. For example, 100 Hz on DisplayPort requires a cable with a bandwidth of at least 25.92 Gbps. If the screen flickers or "breaks" at high frequencies, check the cable.

⚠️ Note: When connecting to a MacBook (especially on chips) M1/M2) The monitor may not show the maximum resolution. Solution: Go to System settings → Screens and manually select mode 3440×1440 (Low Resolution).

2. Basic settings in the OSD menu: brightness, contrast, color profile

The monitor buttons are located on the bottom bezel on the right. To open the OSD menu, press any button and hold for 2 seconds. Navigation is performed with a joystick (a round button in the middle).

• 🌞 Brightness: The optimal value — 30-40% office, 50-70% For brightly lit rooms, too high a value accelerates wear and tear.
• ☀️ Contrast: A factory value of 70% is usually optimal; an increase above 80% can "burn" dark shades.
• 🎨 Color Mode: The choice depends on the task: Standard – universal profile for the office; Movie – warm tones for the movie; Game – rich colors, but often with an excess blue component; sRGB – the most accurate for the design (coverage 99% sRGB).

To fine-tune the color, go to Picture → Color Temperature and select User. You can manually adjust the RGB balance here. For example, if the picture seems too cold, reduce the blue (B) value by 5-10 units. Use the Lagom LCD Test test images to check.

Brightness: 35-40%|Contrast: 70%|Color profile: sRGB (for design) or Standard (for office)|Color Temperature: User (R:50, G:50, B:45)|Response Time: Normal (for work) or Fast (for games)-->

3. Set up resolution and refresh rate in Windows/macOS

Even if the monitor supports 3440×1440@100Hz, the system can automatically set suboptimal parameters.

🪟 Windows 10/11

1. Open Settings → System → Display → Additional display settings.
2. In the Adapter Properties section, select the List of all modes.
3. Find a line with a resolution of 3440×1440 and a frequency of 100 Hz (if it is not available, update the graphics card driver!).
4. Apply the changes. If the screen goes out for 15 seconds, that's OK (the monitor switches mode).

🍎 macOS (M1/M2)

On Apple's Silicon chips, the monitor can be displayed as 3840×1080 (stretched image).

1. Hold Option (Alt) and click on Scaled in the screen settings.
2. Select 3440×1440 (Low Resolution)
3. If the picture is blurry, install BetterDummy to create custom resolution.

Critical feature: when connected via USB-C to a MacBook, the monitor does not support 100 Hz – a maximum of 60 Hz. This is a limitation of the DisplayPort Alt Mode protocol in Apple chips.

4. Optimization for games: FreeSync, response time, crosshair modes

For gamers, the Xiaomi Mi Surface Display 34 offers a few key features that often go unused:

• 🎮 FreeSync Premium: Activated in the monitor menu (Game) → FreeSync. requires: Video card to work AMD (Radeon RX 5000+) or NVIDIA (series GTX 10/RTX 20+ driver-driven 430.39+). Connecting to DisplayPort (via DisplayPort) HDMI Not working!). G-Sync Compatible option enabled in the control panel NVIDIA (green-card).
• ⚡ Response Time: In the Game Menu → Response Time modes available: Normal for work (minimum artifacts); Fast for games (response time) ~5 ms, but ghostly images are possible; Faster for eSports (response time) ~3ms, but strong artifacts in dynamic scenes).
• 🎯 Sight modes: In Game → Crosshair can be turned on virtual crosshairs (4 variants). CS2 or Valorant, where the software sight is disabled.

To check FreeSync, use the test on the TestUFO website. If the screen starts to "break" at an FPS below 48, turn on Low Framerate Compensation (LFC) in the AMD driver settings.

⚠️ Warning: When Faster (Response Time) is activated, dark game scenes (such as Cyberpunk 2077) may show noticeable artifacts in the form of shadows behind moving objects.

💡

To reduce the input lag in games, disable all post-processing in the graphics settings (for example, NVIDIA Reflex or AMD Anti-Lag) and set the power consumption mode in the driver to Maximum Performance Preference.

5. Professional calibration for design and video editing

If you work with color (such as Photoshop or Premiere Pro), the factory profile of sRGB may not be accurate enough. Professional calibration will require a hardware calibrator like the X-Rite i1Display Pro or Datacolor SpyderX.

1. Install a calibration program (for example, DisplayCAL or proprietary calibrator software).
2. From the monitor menu, select the sRGB profile and set the brightness to 120 cd/m2 (standard for printed products).
3. Connect the calibrator to the PC and place it on the screen according to the instructions.
4. Start the calibration process with the target sRGB profile or DCIP3 (for HDR-content).
5. Keep what you got. ICC-profile and assign it by default in the settings Windows/macOS.

After calibration, check the result on the test images:

• 🖼️ Black test – all shades from 0 to 255 should be distinguishable.
• 🌈 Gradient test – there should be no sharp transitions or stripes.
• 🟢 Gamma test – all squares should merge with the background.

If you don’t have a calibrator, use manual settings for reference images. For example, to adjust the gamma, change the Gamma value from the Picture → Advanced menu (optimum: 2.2).

6. Solving common problems

Even after setting up correctly, Xiaomi Mi Surface Display 34 users face typical problems, and here are the most common ways to solve them:

If the monitor suddenly began to "glutch" (artifacts, spontaneous reboots), reset the settings:

1. Turn off the monitor.
2. Press the Menu button and hold for 10 seconds.
3. Turn on the monitor - all settings will return to the factory.

⚠️ Note: When connecting to laptops with hybrid graphics (Intel) + NVIDIA/AMD) The monitor can run unstablely at high frequencies. Solution: In the graphics control panel, link applications to a discrete graphics card.

7 Additional features: PIP, KVM, and management via Mi Display App

Xiaomi Mi Surface Display 34 supports several “hidden” features that are rarely mentioned in the manual:

• 🖥️ Regime. PIP (Picture-in-Picture: Allows you to display images from two sources at the same time. → PIP. For example, you can connect a PC via DisplayPort and a laptop via HDMI, And then you can put the window on the laptop over the main screen.
• 🔄 KVM-switch: If two devices (e.g., a PC and a laptop) are connected to the monitor, you can switch between them with a single button (Source), while the keyboard and mouse (connected to the monitor) USB-monitor hubs will be automatically reassigned.
