Ive recently had to look for a non Apple Monitor for a new Mac book pro. I went for the Dell UltraSharp 27 Monitor - it was recommended on a Mac user forum. Its OK. - it isn't as pretty as an Apple product but its fairly sharp (not as sharp as my Retina display iMac at work) especially if you adjust the settings, the colours are pretty good and its fairly fast. Connecting it to my brand new MacBook Pro was a pain! If you need to do the same Ive found two connectors that worked. I went for a USB Type_C to DisplayPort Cable - Google make one: https://store.google.com/product/usb_type_c_to_displayport_cable and so do Kamex: https://www.amazon.com/Kanex-DisplayPort-Adapter-Support-Inches/dp/B01C8PIMUE Both apparently support 4K. I also bought a sound bar for the dell - fitted it ok - hooked up via the USB as per instructions - I can't get any sound output out of it - any help to get it working gratefully received! Thanks.
