Problems with the resolution of the display

My display resolution can support 3840*2160 60hz, but after installing Sonoma14.3.1, the screen resolution can only be displayed like a fish screen. The default resolution is the same. What's the problem?

1.7 GHz six-core Intel Core i5

Intel UHD Graphics 630 1536 MB

32 GB 2666 MHz DDR4 14.3.1 (23D60)

The system model uses imac19.2
