What to use as a second monitor?

I currently have a 32" Samsung G80SD as my main monitor and a 1080 asus 23" ish monitor as a second.

I know i want to get a duel monitor arm, but what monitor would you pair with the Samsung as the second monitor is purely for discord, steam, youtube etc and not gaming. Was hoping to find a similar style/colour as the Samsung (silver)

And also the best position for the second?

Any suggestions?

Thanks
