First off I hope this is the right area for posting this question. I have an LG 4K monitor that has an audio out outlet in the back of it and wanna use earbuds connected to the monitor for sound. I was told that the audio out in the back of the monitor is only for use with adding external speakers. Could anyone tell me if there's a way to get sound to my earbuds / headphones using that outlet in the back of the monitor? Like a cable or something? so instead of an external speaker I can use my headphones?
