The right resolution and refresh-rate setup on a KTC monitor may depend on the target resolution, the matching refresh rate, and the signal path. Check the parts that match your setup. If these steps do not fit your screen, use the model links below for exact instructions.
What to check
Check the target resolution
Begin with the resolution the monitor is meant to use most often.
Check this:
- Open the display settings on the source device.
- Choose the KTC monitor if more than one screen is connected.
- Set the resolution to the target value shown for the monitor.
- Apply the change and confirm the picture looks normal.
If the image looks stretched or blurry, the current resolution may not match the panel correctly.
Check the matching refresh rate
After the resolution is correct, choose the refresh rate the setup can support reliably.
Check this:
- Open the advanced display options on the source device.
- Choose a refresh rate that matches the monitor, cable, and port in use.
- Apply the change.
- Check that the screen stays stable.
Higher refresh rates are more sensitive to cable quality and adapter limits.
Check the signal path
If the target combination does not appear or the image is unstable, simplify the setup first.
Check this:
- Disconnect docks, splitters, and extra adapters.
- Use one direct cable from the source device to the monitor.
- Set the resolution and refresh rate again.
- Add other devices back only after the stable mode is confirmed.
This helps separate a monitor setting problem from a cable-path limit.
If the steps above do not match your screen
Before going to the model list, try these quick checks:
- confirm that the source device is connected to the correct input
- reconnect the cable or try another port if the expected mode is missing
- start with a safer mode such as 1080p at 60Hz if the screen goes black
- compare HDMI, DP, or USB-C if more than one path is available
