Amazon.com: Dell Ultrasharp U2718Q 27-Inch 4K IPS Monitor …

The firmware on my monitor is M2B103, which I haven’t yet verified is the very newest, but I have absolutely no problems with any weird colors using display port for my connection. Other thoughts: While this monitor has an anti-reflective coating I do notice a little light glare when there’s a lot of bright light coming from a window.
