monitor.
3. This monitor features ventilation openings on the back of the unit. Avoid blocking
these openings to prevent the monitor from overheating.

Section 6: Basic Operation
1. Insert one end of the DP cable (included) into your PC’s graphics card. An HDMI
cable (not included) or, in some cases, a USB Type-C cable can also be used.
Monitor resolution can be limited based on the input/cable used (i.e., DP vs
HDMI).

3. Connect the power cable to your monitor, then connect the other end to your
power source. It is recommended that you use a surge protector with adequate
voltage if a wall outlet cannot be reached directly.
4. Locate the power button on the monitor and press and hold it for ~6s to turn the
monitor on.
If you cannot locate the power button, please refer to Section 3.1.
Adaptive Sync
Adaptive sync eliminates image tearing, stuttering and ghosting by adjusting of a
monitor’s vertical refresh rate to the frame rate of the graphics card. It is compatible
with GPUs that use AMD® FreeSync™ or NVIDIA® G-Sync™. The feature is off
on VIOTEK monitors by default and must be manually enabled in the monitor’s
OSD (see Section 8: OSD). To use this feature, the connecting device must be
compatible with adaptive sync (FreeSync and/or G-Sync); have the latest graphic
drivers; and be connected to the monitor using a DisplayPort (DP) cable.
Section 7: Indicator Light
Solid blue light indicates power is on and the monitor
is operating normally. Flashing blue light indicates
no video source, no horizontal/vertical signal has
been detected or voltage is low. Please ensure
your computer is on and all video cables are fully
connected. Indicator light
