Operating Instructions

On-Screen Display (OSD) Navigation

The monitor features a joystick control located on the back for navigating the OSD menu. Press the joystick to open the OSD, then move it up/down/left/right to select and adjust settings.

Common OSD settings include:

• Picture Mode: Adjust display settings for different content types (e.g., Standard, Game, Movie, sRGB, DCI-P3).
• Brightness/Contrast: Fine-tune the display's luminance and contrast levels.
• Color Temperature: Adjust the color warmth or coolness (e.g., Warm, Cool, User).
• Input Select: Manually switch between connected input sources (DP, HDMI 1, HDMI 2, Type-C).
• Adaptive Sync: Enable or disable Adaptive-Sync for smoother gaming.
• KVM Switch: Manage KVM functionality if multiple devices are connected via Type-C and USB upstream.
• Sleep Mode: Configure the monitor's sleep behavior.
• Pixel Refresh: Access OLED care functions like pixel refresh.

Note: Some users have reported the OSD being slow or HDR settings resetting. Ensure your monitor's firmware is up to date for optimal performance.

KVM Functionality

The KVM (Keyboard, Video, Mouse) feature allows you to control two different computers with a single keyboard and mouse connected to the monitor. To use KVM:

1. Connect your primary PC to the monitor via DisplayPort or HDMI and the USB upstream cable.
2. Connect your secondary device (e.g., laptop) to the monitor via the Type-C cable.
3. Connect your keyboard and mouse to the USB downstream ports on the monitor.
4. Use the OSD menu or a dedicated hotkey (if available) to switch between the primary and secondary devices, transferring control of the keyboard and mouse.

Optimal Gaming Experience

To fully utilize the monitor's gaming capabilities:

• Ensure your graphics card drivers are up to date.
• Set the display resolution to 2560x1440 and refresh rate to 240Hz in your operating system's display settings.
• Enable Adaptive-Sync (or FreeSync/G-Sync compatible) in your graphics card control panel and the monitor's OSD.
• For HDR content, ensure HDR is enabled in Windows display settings and the monitor's OSD. Adjust color temperature to "Warm" for optimal HDR appearance.

Maintenance

Proper maintenance will extend the lifespan of your OLED monitor and ensure optimal performance:

• Cleaning the Screen: Use a soft, lint-free cloth specifically designed for electronics. Gently wipe the screen to remove dust and smudges. For stubborn marks, slightly dampen the cloth with distilled water or a screen-cleaning solution. Do not spray liquid directly onto the screen.
• Cleaning the Body: Use a soft, dry cloth to wipe the monitor's casing and stand.
• OLED Care: OLED panels are susceptible to image retention (burn-in) if static images are displayed for extended periods. The monitor has built-in pixel care functions (e.g., Pixel Refresh, Screen Shift) to mitigate this risk. It is recommended to enable these features and allow them to run periodically, especially when the monitor is powered off.
• Power Off: When not in use for extended periods, it is recommended to turn off the monitor completely rather than just putting it into sleep mode, as this allows pixel refresh cycles to run.
• Avoid Static Images: Minimize displaying static elements like desktop icons, taskbars, or game HUDs for very long durations. Utilize screen savers or dynamic wallpapers.
• Ventilation: Ensure adequate airflow around the monitor to prevent overheating. Do not block ventilation openings.

Troubleshooting

This section addresses common issues you might encounter with your KTC monitor.

No Power / No Display

• Ensure the power cord is securely connected to the monitor, the power adaptor, and the wall outlet.
• Verify the power outlet is functional by plugging in another device.
• Check if the power button on the monitor is pressed.
• Confirm that the correct power cord for your region is being used. If not, contact support for a compatible one.

No Signal / Blank Screen

• Ensure the video cable (DisplayPort, HDMI, Type-C) is securely connected to both the monitor and your computer/device.
• Press the OSD joystick to open the menu and select the correct input source.
• Check your computer's display settings to ensure the output is configured for the monitor.
• Try a different video cable if available.

Image Quality Issues (Blurry, Distorted, Incorrect Colors)

• Ensure the display resolution is set to 2560x1440 in your computer's display settings.
• Update your graphics card drivers to the latest version.
• Reset the monitor's OSD settings to factory defaults.
• If HDR colors appear incorrect, ensure the color temperature in the OSD is set to "Warm" when HDR is active.
• Perform a pixel refresh cycle via the OSD menu if you notice any image retention or uniformity issues.

OSD Menu is Slow / Unresponsive

• This can sometimes be a firmware issue. Check the KTC support website for any available firmware updates for your model.
• Ensure the monitor is not under heavy load or experiencing a temporary software glitch. Power cycle the monitor.

Pixel Shifting / Asymmetrical Borders

• OLED monitors often employ pixel shifting as a burn-in prevention mechanism. This is normal behavior and typically not user-configurable to disable.
• If the shifting is distracting, ensure the monitor's firmware is updated, as improvements may be made.
