Pavillion 23xw Purple Screen when Mac Mini Wakes

HP Recommended
Pavillion 23xw
macOS 10.15 Catalina

I've had the Pavillion 23xw monitor for a few years now. For the first couple, it was hooked up to a 2012 MacBook Pro through a thunderbolt to HDMI adapter, and everything worked fine.

 

I bought a new Mac Mini last November and hooked it up to the monitor directly through HDMI. Occasionally upon waking the computer/monitor, there would be static on the screen. I'd have to turn the monitor off and back on and it would be fine until everything went to sleep again. This didn't happen all the time, so it was okay.

 

But for the last few months, every time the computer/monitor wake up, the screen has a very purple hue to it, and after a few seconds everything goes to static. This will last indefinitely, or until I manually turn the monitor off and back on, and is very annoying.

 

I've tried different HDMI cables, and I've tried plugging different devices into the monitor and those devices didn't have the same issue. I took the Mac Mini in to Apple to check out and do diagnostics on, eventually also wiping the hard drive and reinstalling everything. They didn't find anything wrong, and the problem persists.

 

I tried changing display settings on the computer, and I tried changing settings on the monitor itself, but nothing I do produces a real solution.

 

Anybody have any ideas on this one?

@JTWilcox Welcome to HP Community!

 

To fix incorrect colors, complete the following steps:

  1. Check the video cable connections and make sure the connection is not loose. Tighten the connection screws if the connector is loose.

  2. Press the Auto or Autoselect button on the display.

  3. Press Menu, and select Factory Reset. If the screen is still discolored, continue to the next step.

  4. If the display has more than one type of connection available such as VGA, DVI, or HDMI, try a different type of connection.

  5. If possible, connect the display to another computer. If the colors are incorrect when the display is connected to the second computer, the display might be damaged or defective.
