Contact us onlineGET MORE FROM YOUR MONITOR
Monitor setup & everyday use
Select a question to see the answer. Features and connection limits vary by model; check your product specifications and user manual.
Why does my monitor show “No Signal” or a black screen?
Check that the monitor has power and the computer is awake. Select the input that matches the connected cable in the monitor menu. Reconnect the cable securely at both ends. If possible, test a different cable or source device and connect directly without a dock or adapter. Contact KOORUI if the issue continues.
How do I enable the advertised refresh rate?
In Windows, open Settings > System > Display > Advanced display, select your monitor and choose a supported refresh rate. The available options depend on the resolution, monitor input, computer, cable and any dock or adapter. Check your model's supported modes; some dual-mode monitors require a lower resolution to use their highest refresh rate.
Should I use HDMI or DisplayPort?
Use an input supported by both your monitor and your computer or console. The maximum resolution and refresh rate can differ between inputs and models. Check the supported timing information in your user manual and use a cable rated for that mode. Connecting directly can help identify limitations caused by a dock or adapter.
Why is there no sound from my monitor?
First check whether your model has built-in speakers; an audio output socket does not mean speakers are included. If speakers are supported, select the correct audio output on your computer or console and check volume and mute settings. Models without speakers need an appropriate external audio device.
Why does my USB-C connection not display an image?
A USB-C connector alone does not guarantee video support. Check that the monitor accepts video through that port, the source supports a compatible video output such as DisplayPort Alt Mode, and the cable supports video. Portable models may also need a separate power connection. Follow the connection instructions for your specific model.
How can I make text and images look clearer?
Set your computer to the monitor's native resolution and use an appropriate display scaling setting. Check the monitor's picture mode and sharpness settings. For HDR content, confirm that your monitor and source support HDR and that the relevant settings are enabled. If ordinary desktop content looks washed out, compare the image with HDR turned off.
What should I check if the screen flickers or briefly goes black?
Check the signal cable and power connections, then test a supported resolution and refresh rate with a direct connection. Update the graphics driver from the computer or GPU manufacturer's official source. If available, temporarily turn off HDR or adaptive sync to help isolate the cause. If the problem persists, send KOORUI your model, connection details and a short video.
Can I attach my monitor to a monitor arm or wall mount?
Check your model's VESA mounting pattern, monitor weight and required screw size and depth. The arm or mount must support all of these requirements. Follow the monitor and mount instructions, and do not force screws or use screws that are too long. VESA support and hardware requirements vary by model.
How should I clean the screen?
Turn off the monitor and disconnect power. Gently wipe the screen with a clean, soft, lint-free cloth. Do not press firmly or spray liquid directly onto the screen. Follow the cleaning instructions in your model's manual and avoid abrasive materials or household cleaners unless the manufacturer specifically permits them.
