Quick Access Blue Light Filter Setup

Enabling and disabling the Blue Light Filter can be done on the fly via the Quick Access Key.

NOTE: When enabling the Blue Light Filter (BLF) via the Quick Access Key, the BLF value will be 100 which is certified by TÜV. However, the BLF value will be 0 if the user chooses another function via the Quick Access Key.

While using and enjoying your monitor please keep the following in mind:

Viewing computer screens for extended periods of time may cause eye irritation and discomfort. To reduce these effects, it is recommended to take periodic breaks from viewing to allow the eyes to relax.
Users can customize the Blue Light Filter value through the Game Modes Menu.

The monitor also supports Flicker-Free, which reduces or eliminates screen flicker, thus easing potential eye strain.

Calculating Breaks

When viewing the monitor for extended periods, it is recommended to take periodic breaks from viewing. Short breaks of at least five (5) minutes are recommended after one (1) to two (2) hours of continuous viewing. Taking shorter, more frequent breaks are generally more beneficial than longer, less frequent breaks.

Looking at Distant Objects

While taking breaks, users can further reduce eye strain and dryness by focusing on objects that are further away from them.

Eye and Neck Exercises

Eye Exercises

Eye exercises can help minimize eye strain. Slowly roll your eyes to the left, right, up, and down. Repeat as many times as needed.

Neck Exercises

Neck exercises can also help minimize eye strain. Relax your arms and let them hang at your sides, bend forward slightly to stretch the neck, turn your head to the right and to the left. Repeat as many times as needed.

ViewScale

KVM

The KVM function allows the user to control two computers connected to the same monitor from a single keyboard and mouse.

NOTE: Only applicable in PBP (Picture-by-Picture) and PIP (Picture-in-Picture) mode.

To connect the two computers to the monitor:

Connect one end of the USB Type C cable to the USB Type C port of the monitor. Then connect the other end of the cable to the USB Type C port of the notebook.
Connect one end of a DisplayPort cable to the DisplayPort of the monitor. Then connect the other end of the cable to the DisplayPort or mini DP of the computer.
Connect the USB Type B male cable (square with 2 cut corners) to the USB Type B port of the monitor. Then connect the other end of the cable to the USB port of the computer.

NOTE:

To have a better online gaming experience, and achieve maximum refresh rates, please use a PC to play.

Using Type C will have a power charging function, therefore the graphics card will slow down and downscale the refresh rate to have better performance.

To enable PBP mode:

Press the [●] key or move the Joy Key [▲] or [▼] to display the On-Screen Display (OSD) Menu.
Move the Joy Key [◄] or [►] to select Setup Menu. Then move the Joy Key [▼] to enter the Setup Menu menu.

Move the Joy Key [▲] or [▼] to select Multi-Picture. Then move the Joy Key [►] to confirm the selection.
Move the Joy Key [▲] or [▼] to select PIP. Then press the [●] key to enable PBP mode.

To activate the KVM function:

Move the Joy Key [►] to activate the KVM function.
Then you will be able to switch the cursor between the two screens (left/right window).

NOTE: Under PBP and PIP when the monitor auto detects that the USB B and USB C ports are in use, a reminder message will pop up that the monitor supports KVM.

HDMI CEC (Consumer Electronics Control)

The HDMI CEC function allows the user to power on devices connected to the monitor via the HDMI ports when the monitor is powered on.

NOTE:

HDMI CEC will also need to be activated on the connected devices.

Ensure the external device(s) is/are connected via the HDMI port(s).

Press the [[●] key or move the Joy Key [▲] or [▼] to display the On-Screen Display (OSD) Menu.
Move the Joy Key [◄] or [►] to select Setup Menu. Then move the Joy Key [▼] to enter the Setup Menu menu.
