Hi Tony! I posted the very first review for this great computer. The monitor I chose was the LG - 27UK600-W 27" IPS LED 4K UHD FreeSync Monitor . . . and I love it. Best Buy had a great price on it at the time. No, you don't need an HP monitor at all, although they are very good as well. The only tricky thing initially was finding the on/off switch for the monitor LOL! It's located near the top of the pedestal arm on the back of the monitor. I know you're set on a 32" monitor and there are great choices for those as well. I too was initially thinking I wanted a 32" monitor, but chose this 27". I think you'll choose what is best for you.
