I needed to buy a new monitor and since Apple don’t supply one at the moment I spent a week searching through online reviews and then looking at a selection at various stores. Eventually decided to get the Dell P2715Q 27-Inch Ultra HD 4K LCD Monitor. Very happy with the selection I just hope Apple don’t announce a new monitor next week!

I should have noted that you have to buy a separate AmazonBasics High-Speed HDMI 2.0 Cable - 0.9m / 3 Feet (Latest Standard) Supports Ethernet, 3D, Audio Return . Also if you need a Mac compatible web cam, this one is highly regarded.
