Hi, I'm Ric, an independent advisor. I'm sorry you're experiencing this issue. I totally get how frustrating display and USB-C issues can be, especially with high-spec monitors like the Dell P3223QE.
Try these steps:
- You must connect via USB-C using a USB-C cable that supports full DisplayPort Alt Mode + USB 3.x data (not just charging or USB 2.0). The “Display connection might be limited” error usually means the cable doesn’t support video or full data.
Recommended cable:
A USB-C to USB-C cable with:
> USB 3.2 Gen 2 or Thunderbolt 3/4
> DisplayPort Alt Mode support
> 4K@60Hz and HDR capable
(e.g., from certified brands like Anker, Cable Matters, Belkin, or Club3D)
- To get 4K@60Hz + HDR
> Either USB-C to USB-C (with proper spec as above)
or
> USB-C to DisplayPort (monitor DP input), this also works well for high resolution + refresh rate
The USB-C to DisplayPort method won't enable USB-A/Ethernet on the monitor though, since it's display-only.
Make sure your Lenovo Legion 5 USB-C port supports DisplayPort + data (it usually does, but confirm in specs)

Hope this helps, otherwise, I would be happy to assist you further.
