Frequently Asked Questions - JN-IPS27G300Q-HSP Japannext

How to assemble the monitor?

Place the screen face down on a soft cloth. Insert the stand hook into the rear mount, then secure the base with the provided screw. Ensure the assembly is sturdy before uprighting the monitor. To adjust tilt, hold the top and bottom bezels and apply gradual pressure.

How to connect the monitor to my computer?

Turn off the monitor and computer. Connect the power cable and an HDMI or DP cable (one at a time) to the monitor, then to the computer. Turn on both devices. Ensure the input source is correct in the OSD menu.

How to adjust brightness or contrast?

Press the M button to open the OSD menu. Navigate with the ▲/▼ keys to Brightness/Contrast. Use ▲/▼ to adjust Brightness (0-100) and Contrast (0-100). Press M to confirm and E to exit.

What to do if the screen does not turn on?

Check that the power button is pressed and the power cord is properly connected to the monitor and outlet. Ensure the outlet works. If the indicator is on but no image, check the signal cable connections and that the computer is on.

What to do if the image is blurry or unclear?

Set your computer's display resolution to the monitor's native resolution (2560 x 1440). Check that the signal cable pins are not bent and the cable is in good condition. You can also adjust Sharpness in the OSD menu (0-5).

How to activate HDR mode?

Press the M button to open the OSD menu. Go to Menu > Image Mode > HDR. Set to Auto or OFF depending on your content. Ensure your source and content are HDR compatible.

How to use the crosshair?

The crosshair appears by pressing the ▼ key (Hotkey1 by default). To customize, go to OSD Menu > Game Crosshair and choose from 4 styles or disable it. It disappears by pressing E.

What to do in case of dead pixels or image retention?

A few pixels always on or off are normal and not a defect. If image retention persists after prolonged static display, turn off the monitor for a few hours to recover. Avoid displaying static images for too long.

How to reset to factory settings?

Press M to open the OSD menu, go to Reset and select On (or YES). This will restore all default settings.

  Do not use the monitor where it may become wet or exposed to water.
• Do not open and never cover the monitor case because it contains high voltage parts inside which could cause serious injury or fire if you come into contact with them.
• If the power supply is damaged, please contact our customer service or your dealer. Never attempt to inspect or repair the product yourself.
• Before use, please ensure that all cables are properly connected and the power cord is not damaged. If you discover any damage or blurred areas, please contact your dealer immediately.

Before cleaning the monitor, turn off the power and unplug all cables and cords.

How to maintain the monitor:

• LCD panel area: Do not use tissue paper, etc., instead use a clean, soft cloth specially designed for LCD panels. Please wipe the monitor gently. For difficult-to-remove stains, use a neutral cleaner specifically designed for LCD panels.
• Monitor frame: Wipe with a soft cloth dampened with a mild cleaner.

The symptoms listed below are normal conditions for the monitor

• When first used, the screen may flicker due to the nature of the backlight. If this symptom appears, please turn off the monitor and then turn it on again.
• Depending on your desktop setup, displayed colors, and brightness, brightness may appear uneven.
• Several pixels may or may not always be lit.
• If you display the same image for a long time, an afterimage from the previous image may persist even after switching to a different image.

In this case, the screen will recover slowly. Otherwise, turn off the power for a few hours and the problem will be fixed.

Instead of trying to repair the monitor yourself, contact customer service or the dealer.
