Dell Intel 12th generation CPU (i5-12400), integrated graphics (UHD
Graphics 730)
Monitor is AOC 27 inch, the standard resolution is 2560x1440
After installing Ubuntu 22.04, the maximum resolution of the
display(using HDMI cable) can only maximum support 1980 x 1080
I have upgraded the kernel to 6.14, but it still doesn't work.
When install Ubuntu22.04 on a Dell computer with an Intel 11th
generation CPU (i5-11400, integrated graphics) or below, the resolution
2560x1440 is supported and works well through HDMI.
