If your EVICIV portable monitor displays an endless flashing color pattern instead of going to sleep when the video signal is lost, this may help.
This was tested on a monitor identified as:
- Brand: EVICIV
- OEM: CYS
- EDID Product Name:
ASM-160QC - Controller:
SVN3102 - Firmware:
S001 - Panel:
NE160QDM-NY1(16", 2560×1600, 120 Hz)
When the host computer enters sleep or turns off the display (DPMS, HDMI signal loss, etc.), the monitor does not enter standby.
Instead, it displays a flashing color pattern (red, green, blue, white, etc.), which is extremely distracting.
This behavior occurs regardless of whether the signal loss is triggered by:
- Windows display sleep
- Linux DPMS (
xset dpms force off) - Disconnecting HDMI
- Disabling the output with
xrandr
The issue is not related to the operating system or graphics driver. It is controlled by the monitor firmware.
- Turn the monitor off using the power button.
- Push and hold the joystick downward.
- While still holding the joystick down, turn the monitor on.
- The hidden Factory Menu should appear.
Inside the Factory Menu, locate:
Burnin : On
Change it to:
Burnin : Off
That's it.
After changing this setting, the monitor enters a proper standby mode when the video signal disappears instead of displaying the flashing color pattern.
If the monitor keeps opening the Factory Menu instead of the normal OSD:
- Disconnect USB-C power.
- Hold the Power button and push the joystick downward.
- Reconnect USB-C power.
- The monitor will briefly power cycle.
- The normal user OSD is restored.

The Burnin option appears to control the firmware's "No Signal" demo/test mode rather than only a burn-in test.
Changing it from On to Off disables the flashing color animation and restores normal standby behavior.
Other factory menu options (ADC Gain, ADC Offset, Panel settings, Memory Work Select, etc.) should not be modified unless you know exactly what they do.
If you have the same OEM monitor sold under another brand (AOSIMAN, EVICIV, etc.) and the EDID identifies it as ASM-160QC, this procedure may also work for your device.
