2 stunning 4k monitors. I bought the both in July and have them connected to a mac book pro. I'm selling them only because I'm moving overseas and moving monitors is tricky I don't want to risk it. It has 3 inputs: 2 HDMI and 1 Display port. I can throw in for free also 2 USB-C to Display Port cables (they can be quite expensive).
