Is very-small second monitor a thing?

Want a second monitor to play Youtube vids while I game to satisfy my short attention span zoomer brain. But my desk don't have that much of a space, and not much a need for a regular sized second monitor. Just putting my phone next to me works functionally, but the audio wouldn't be coming from the same source (headset), and it's a hassle to setup some sort of dual sound source. So I'm wondering if there are any ultra small monitor available on the market that are in the range of iphone-to-ipad size.
