S2817Q, MacBook Pro, works!

Question

I am using an S2817Q with a MacBook Pro 13' laptop. It works beautifully. When I used this monitor with windows I used the Dell Display Manager. It was nice. But I don't miss it. The Mac handles the display very nicely. You can buy cheap dongles to adapt the Thunderbolt output of the Mac to either DP or HDMI, both of which are supported by the monitor. MacOS has a nice feature that allows you to grow or shrink everything on each monitor, so you can run the S2817Q in full 4K resolution but make everything a bit bigger through this simple Display Setting. Windows has that too but you have to log out and back in to change it. Mac is better in that way.  The Dell Display Manager feature of locking windows into a grid of your choice was cute but I don't miss it on Mac. You use Mac features instead like Spaces and app switching. It's really a better monitor for Mac than it was for Windows; with Windows I wished I had bought a smaller HD (not 4K) monitor. The big problem with this monitor and Mac is the built-in loudspeakers. Apple has a limitation, when you plug in a monitor via HDMI or DP with built in loudspeakers, you cannot control the volume from the computer. It's a royal pain. And to make it worse, the Mac software volume controls are totally disabled when this monitor is plugged in so you cannot control the volume of the laptop's internal speakers or headset either!!!! Totally stupid design by Apple. Not Dell's fault but it's painful.

You replied to an older thread with a different monitor model, so started a new thread.

It is great that the S2817Q works on the non-tested/non-validated MacBook Pro. For other Apple users who may be looking =

Which version of TB (Thunderbolt) is on your MacBook Pro?

What specific cables are you using?

I also have it working with a new Mac mini 2018 running Mojave 10.14.1. Everything seems to work fine when I connect it via HDMI using the cable that came with the monitor, both before and after turning on HDMI 2.0 support. It doesn't like setting the Response Time to "Fast", though, as there are visible halos around text when scrolling.

Using Thunderbolt with a cable I purchased at Frys (PPA is the manufacturer), however, I get some weird magenta lines across the screen whenever the display sleeps. Last night it apparently filled the screen with them and stayed on all night. The cable says it supports everything I think it is supposed to (copied from Frys website below):

After hooking up my Dell 28' S2817Q monitor to my 2017 Macbook Pro I get a still photo that is not the same one on my MacBook Pro. I do get a bar across the top with all the icons and options like 'edit', 'view' 'Window' etc. And when I click on system preferences and then 'display' I get small windows on both the macbook and the monitor but they are not the same. So there is something happening between my MacBook Pro and the monitor. It is like it is trying to connect but cannot.
