Buying an ultra-wide gaming display is only the first step to immersing yourself in virtual worlds, but the real quality of the picture is revealed only after a competent configuration. Many users, when unpacking the Xiaomi Mi Curved Gaming Monitor 34, encounter faded colors, low brightness or lack of a declared refresh rate of 144 Hz. This is because factory settings are often focused on in-store demonstration, rather than comfortable use at home.
In this guide, we will take a closer look at the connection process, operating system settings, and fine calibration of the image, learn how to activate HDR mode, eliminate blur in dynamic scenes, and adjust contrast correctly for text, and follow these guidelines to make the most of the VA matrix and experience the benefits of 21:9.
Before you start the software part, you need to make sure that the physical connection is correct. Using poor-quality cable can become a (bottleneck) of the whole system, not allowing you to transmit a high-resolution signal with a high frame rate. Make sure you use a certified DisplayPort 1.4 or HDMI 2.0 cable that comes with the kit, as older cables may not support the bandwidth required for a resolution of 3440×1440.
Initial connection and interface selection
The key for owners of this model is to choose the right video output. Although the monitor supports HDMI connectivity, the DisplayPort port is a priority for achieving maximum performance. Through HDMI, it is often impossible to activate refresh rates above 100 Hz or 120 Hz at full resolution, which is critical for shooters and racing simulators.
Once you connect the cable to the graphics card and monitor, you need to manually select the source of the signal if the image does not appear automatically. To do this, click the control joystick on the bottom of the case and select the appropriate menu entry. If you use a discrete graphics card, make sure that the cable is connected to it, and not to the motherboard connector.
⚠️ Note: When using adapters (e.g. DP-to-HDMI), FreeSync will not work and the maximum frame rate will be limited by the standard. HDMI 1.4, what 60-75 Hz for this permit.
For Thunderbolt 3 or 4 laptop owners, USB-C connectivity is possible if your monitor model has the appropriate port, allowing both video and laptop charging at the same time, but games still prefer direct connection to a discrete card via DisplayPort to minimize input delay.
Setting Update Frequency and Resolutions in Windows
Once the monitor is defined by the system, the standard desktop resolution can be set to 1920×1080 or 60Hz. To fix this, open Windows Settings, go to System and select Display. At the bottom, find the link "Additional Display Settings."
In the window that opens, make sure that the native resolution 3440×1440 is selected in the drop-down list. Next, click on “Display Video Adapter Properties 1” and go to the Monitor tab. Here in the “Screen Update Frequency” list, you need to select a value of 144 Hz. If this is not the case, check the graphics card drivers.
For graphics card users NVIDIA You need to go to the "control panel" NVIDIA» → «Change resolution. In the PC Modes section, select the 32-bit color depth and color format RGB Or YCgCo-R for better image quality. AMD Radeon similar settings are in the "Display" section» → «Custom Resolutions».
☑️ Checking the Windows settings
Importantly, when using G-Sync Compatible technology (for Xiaomi monitors this works through the VESA standard), you should also go to the “G-SYNC settings” section in the NVIDIA panel and check the “Enable G-SYNC, G-SYNC Compatible” box, which will eliminate frame gaps in games without increasing the input delay typical of a regular V-Sync.
Working with the monitor menu (OSD) and game modes
The settings of the display itself are controlled through a hidden joystick located on the bottom edge of the center. A short tap causes the menu, and rotation allows you to move around points. The first thing to do is switch the profile of the image. The factory mode of "Standard" or "sRGB" often looks pale.
Game or FPS modes are recommended for games, where brightness and dynamic contrast are increased. However, Cinema mode or manual settings in User mode are best for everyday work and watching movies. In-game profiles, Black eQualizer is often activated, which illuminates dark areas, helping to spot enemies in the shade, but this can reduce the overall contrast of the picture.
| Parameter OSD | Recommended value | Impact on the image |
|---|---|---|
| Brightness (Brightness) | 60-80% | Comfort for the eyes during the day, reduces fatigue |
| Contrast (Contrast) | 50-55% | Optimal balance between details in lights and shadows |
| Gamma | 2.2 | Standard for Windows and most games |
| Overdrive | Middle (Middle) | Reduces plumes, but can cause artifacts |
Special attention should be paid to the Overdrive setting (in the Xiaomi menu can be called “Response Time” or “OD”), which speeds up the response of pixels. Setting a value on “Max” or “High” often leads to the appearance of inversion plumes (coronas) around moving objects. The optimal for the VA matrix in this model is usually the value of “Middle” or “Normal”.
Secret button combination
Color calibration and elimination of defects of the VA matrix
The VA-type matrices installed in the Xiaomi 34 are known for their deep black color, but have one feature - the effect of "black crush" and "ghosting" in dark scenes. To minimize the loss of detail in the shadows, do not twist the contrast to the maximum.
To fine-tune colors, use calibration images (like gradient test tables). If you see a black-to-gray gradient fusing into a single spot, increase the Gamma setting slightly or decrease the Brightness. If the whites (white areas) look illuminated, lower the brightness of the backlight.
The DC-Dimming technology in this monitor helps reduce backlight flickering at low brightness levels, which is important for sensitive-eye users. However, when HDR is on, brightness control can go into automatic mode, which sometimes causes discomfort, in which case it is better to turn off HDR in Windows for work with documents.
⚠️ Attention: The "Ghosting" effect is most noticeable at low temperature on the matrix. 10-15 minutes before assessing the quality of the picture, especially in winter.
If you're a photo or video processor, make sure to switch the monitor to sRGB. This mode blocks saturation and brightness settings, bringing colors to standard. For games, this is not the best choice because of the low brightness, but for web surfing and text work, your eyes will tire less.
💡
For quick checks for broken pixels or lights, use online services with monochromatic images (white, black, red). On a black background, you can clearly see the lights at the edges, which is normal for VA matrices, but should not be a torch in the center.
Activate HDR and work with 4K content
Although the monitor has WQHD resolution, it supports HDR (High Dynamic Range) technology. To activate it in Windows 10/11, go to Settings → System → Display and turn on the Use HDR switch. Please note that without the feature enabled in Windows, the brightness and contrast settings in the monitor menu can be blocked.
It is worth noting that the brightness (peak brightness) of this monitor is about 300-400 nits, which is the input threshold for HDR. The real effect of “wow”, as on OLED or Mini-LED TVs, is not worth waiting, but the extended dynamic range in supported games (Cyberpunk 2077, Horizon Zero Dawn) makes the picture more lively.
When you watch it. HDR-Content (YouTube, Netflix, local files) colors may appear faded if the system does not have a profile installed. ICC Or if the content is not labeled correctly, you can use third-party tools like Microsoft's AutoHDR for older games to artificially expand the dynamic range.
💡
True HDR requires brightness from 600 nits and local dimming. On Xiaomi 34, turn on HDR only for specific content, as in a regular Windows desktop, this often makes fonts less clear.
Optimization for different use cases
There is no universal setting, so experts recommend creating profiles for different tasks. For esports disciplines (CS:GO, Valorant), maximum response speed and no breaks are important, and high hertzovka and freeSync enabled are given priority, even at the expense of color reproduction.
For single-player story games (The Witcher 3, Red Dead Redemption 2), visuals are more important, and you can sacrifice a few milliseconds of response to include more aggressive sharpening and saturation settings, and you can turn on "Sharpness" at 50-60% on the monitor menu to compensate for the softness of the VA matrix.
When working with text and office applications due to subpixel structure (non-standard location) RGB-Subpixels on a curved surface may look fuzzy. In Windows, turn on ClearType (through Search for “ClearType Text Customization”) and go through the customization wizard by selecting the most clear lettering options for you.
