First, check if the power adapter is plugged in tightly and if the power cord is damaged. Try replacing the power socket. If the power supply is normal, check if the video cable (HDMI/DP, etc.) between the monitor and the host is connected firmly. You can reinsert it or replace the cable for testing.
Confirm if the host has booted up properly (e.g., check if the fan is spinning). Check if the video cable interface is loose or oxidized; try cleaning the interface and reconnecting. Switch the monitor's signal source (press the "Source" button on the monitor) to ensure it matches the connected video interface (e.g., HDMI 1/DP 1).
Press the keyboard shortcut "Win + P", and you can choose modes like "Second screen only", "Duplicate", "Extend", or "PC screen only". Some laptops need to manually set the external monitor parameters in the graphics card control panel (e.g., NVIDIA Control Panel).
Enter the monitor settings (press the "Menu" button) and adjust the "Clarity" or "Sharpness" parameters. In the computer system (e.g., Windows "Display Settings"), set the resolution to the monitor's native resolution (e.g., set a 2K monitor to 2560×1440) and match the refresh rate to the recommended value (e.g., 60Hz/144Hz).
It may be due to unstable power voltage; try using a regulated power supply. There may be strong electromagnetic interference nearby (e.g., routers, microwaves); stay away from the interference source. Check if the video cable is damaged, or replace it with a shielded cable (e.g., a DP cable is better than an HDMI cable).
Professional users can use a colorimeter (e.g., Datacolor Spyder) with software for calibration. Ordinary users can select preset modes like "Standard" or "sRGB" in the monitor settings, or adjust "Brightness", "Contrast", and "Gamma value" in the graphics card control panel to a visually comfortable range.
The host graphics card needs to support the corresponding refresh rate (e.g., NVIDIA GTX 1660 and above, AMD RX 5500 XT and above), and use HDMI 2.0/DP 1.2 or higher-spec cables. Enable "G-SYNC" or "FreeSync" in the graphics card control panel (requires monitor support) to reduce screen tearing.
It's normal. HDR needs to show its effect in high-brightness scenarios (e.g., games, HDR videos), with clearer dark details. If used on ordinary web pages or documents, you can turn off HDR in the monitor settings and switch to SDR mode.
Avoid displaying fixed images for a long time (e.g., static logos, taskbars). Enable the monitor's "Pixel Refresh" or "Screen Saver". Reduce the screen brightness (it is recommended not to exceed 70%) and shorten the automatic screen-off time.
After turning off the power, gently wipe with a soft microfiber cloth (e.g., an eyeglass cloth). For stubborn stains, you can dip a small amount of pure water or a special screen cleaner (without alcohol) – avoid spraying directly on the screen.
The industry usually stipulates that: if there are no more than 3 bright spots, no more than 5 dark spots, and they are not in the center area of the screen, it is within the normal range. If it exceeds the standard or affects use, you can contact after-sales for inspection and replacement.
An LCD/OLED monitor has a service life of about 5 - 8 years under normal use (8 hours a day). Long-term use at high brightness will shorten the life of the backlight (LCD) or pixels (OLED). It is recommended to adjust the brightness reasonably during daily use.
Check if the stand has a locking screw; loosen it and then try to adjust. Some entry-level monitor stands only support tilt adjustment and do not support lifting or rotation – this is a design feature.
Confirm that the device supports USB-C PD charging (e.g., laptops, mobile phones) and that the power of the monitor's USB-C interface matches (e.g., 65W). Use a full-function USB-C cable (supports data + charging); some cables only support charging or data transfer.
If you have other questions, you can contact the brand's after-sales service or refer to the product manual for more support.
