A pink hue on only one of multiple monitors is usually caused by either a bad connection/cable, incorrect display mode, or a color/refresh setting that doesn’t match the monitor’s capabilities.

Try these steps in order:

1. Check the cable and port
   • Power off the PC and the affected monitor.
   • Reseat the video cable on both ends (unplug and firmly plug back in).
   • If possible, swap the cable with the cable from the good monitor.
   • If the pink hue moves to the other monitor after swapping, the cable or port is the problem.
   • If the PC has more than one video output (HDMI/DisplayPort/etc.), plug the pink monitor into a different output port and test again.
2. Confirm Windows display mode
   • Press Windows logo key + P.
   • Make sure Extend is selected, not Duplicate or Second screen only.
   • If using Duplicate, both monitors must support the same resolution/refresh rate; otherwise, color or image issues can appear.
3. Match resolution and refresh rate to what the monitor supports
   • Right‑click the desktop and select Display settings.
   • Select the pink monitor at the top.
   • Scroll down and set Display resolution to the monitor’s native resolution.
   • Select Advanced display and check Refresh rate.
   • Choose a refresh rate that the monitor supports. If unsure, pick a standard value like 60 Hz.
   • If the monitor is part of a duplicated set and shows tearing or other artifacts, configure a refresh rate that is supported by all monitors.
4. Adjust color settings
   • In Display settings, select the pink monitor and adjust Brightness & color options.
   • If color calibration was changed, search for “calibrate display color” in Settings and follow the wizard to reset/adjust color.
5. Basic hardware isolation
   • Connect the pink monitor to a different PC or device using the same cable.
   • If it is still pink on another device, the monitor itself likely has a hardware or internal setting issue.

If none of these steps help and the issue only affects that one monitor on any device, the monitor hardware is likely faulty and may need service or replacement.
