Get a new cable instead of using the one that came with the monitor. I got this one and it fixed the issue.

We've had a fair amount of clients that have picked up the 90RB002AUS Legion Tower 5, either from the Lenovo website or Best Buy this past week while it was on sale, adding only a 32GB RAM kit to enhance game performance.

Most of them opted for a 27" QHD 2560P monitor worthy of the 3060, making sure to get an optimized VESA Certified DisplayPort cable for outstanding monitor support.

And three of the clients actually purchase three monitors, as it was in their $1500 budget. Our team guesses, if you got room. Still, it's nice to have two monitors.

Hope this information helps
