So my gaming headset broke and until i get a new one i need sound, but my new dell display doesnt have built in speakers. Is it possible that i use my old one and dual monitor it but use the second only for sound
You can if the quality matters more than the sound coming from the correct monitor, just set up the other monitor and if Windows doesn't automatically send sound to it you right click the speaker in task bar, open sound settings and select it for your output.
