That's a Wacom Cintiq Pro 24" on a Wacom Ergo Stand.
Here's that stand: https://www.amazon.com/dp/B07F7ZHNY1/
yeah I know that problem.. ^^;
at the moment i've got a 27" on the left, 27" in the middle, and my 22" Kamvas at the right..
I wish there would be a substitute to the expensive Wacom stand for 500 bugs. that thing allows you to pull down the tablet on you lab, and you have the other Displays behind them fully visible
another idea would be to put the tablet (+ display) on a display arm and move them arround to your needs
