If the LED strips do not work as expected even though Ambiglow is activated, this could be due to the Windows Dynamic Lighting settings. According to the user manual, enabling Dynamic Lighting in Windows may affect the Ambiglow function of the monitor. To check this, navigate to Settings > Personalisation > Dynamic Lighting in Windows 11 or later and disable this function to ensure Ambiglow is working properly. According to our further research, this monitor does not have speakers.

Switch on the Ambilight, perhaps look in the recess of the settings to see if something is switched off. Otherwise, if the screen is switched on, the lighting should work.

Correct, this is the white colour variant. I will pass on the incorrect information to the relevant department, thank you for letting me know!
