Arduino Ambilight on computer monitor

I've managed to get the LEDs working with various libraries but I just can't find good tutorial on how to make make my leds works on my display, all are for different strips/TVs/using kodi or xmbc/old and not working and I myself have no idea what am I doing. I have 2x WS2812B strips and Arduino Uno + Samsung S34E790C monitor (3440x1440) and I would really like if somebody could point me somewhere or just straight up paste the code and instructions here, thanks!

Could you expand a bit on what you expect your LEDs to do?


Stick the leds behind screen while parts change color depending what is on the edges, quick googling of ambilight will give you the idea.
