Connect and position your monitor
Assemble the stand as shown in your model’s manual and place it on a stable surface. Connect the supplied power equipment and a suitable display cable. On a desktop with a dedicated graphics card, use its display output. Select the matching input in the monitor’s on-screen menu. Adjust the screen so text is comfortable to read without leaning forward.
Set the resolution and text size
In Windows 11, open Settings → System → Display and select the correct monitor. Choose its native resolution, normally marked Recommended. Adjust Scale for comfortable text and interface size. Scaling changes the size of interface elements; lowering the display resolution changes the number of pixels in the desktop image.
Choose your refresh rate
Open Settings → System → Display → Advanced display. Select your Koorui monitor and choose the supported refresh rate you want. Check the resolution afterward: some high-refresh choices use a different resolution. The available options depend on the monitor, connection and computer. Microsoft’s refresh-rate instructions explain the Windows controls.
If your expected mode is missing
Check the exact model’s supported input modes. Connect directly to the computer while checking the setup; a dock or adapter can impose its own limit. Use a cable suitable for the required mode and update your graphics driver from the GPU or computer manufacturer. For dual-mode monitors, select the intended mode in the monitor menu before checking Windows again.
Tune the picture for your room
Start with a standard picture preset and a comfortable brightness. Try the available response-time settings in the content you use; the strongest setting is not automatically the clearest. If your monitor supports adaptive sync, use its manual and graphics-driver controls to configure it. For HDR content, use a supported HDR display mode and review both Windows and game settings.
