just installed CentOS 7.8 but the display resolution is 800x600

I just installed CentOS 7.8 on ASRock B460M Pro4 board. CPU is i5-10400.
The display device is inside the CPU and the max resolution is 4096x2160 for HDMI.
But when I connect my small screen (max full HD), the display resolution is only 800x600.
From seeing some info here, I installed EPEL for yum, and inxi.
The "inxi -G" command's output is like this :

Graphics:
Device-1: Intel driver: N/A
Display: x11 server: X.Org 1.20.4 driver: vesa
unloaded: fbdev,modesetting resolution: 800x600~75Hz
OpenGL: renderer: llvmpipe (LLVM 7.0 256 bits) v: 2.1 Mesa 18.3.4

So there is no intel driver and the vesa fall back driver is being used.
How can I install the intel display driver?

I tried installing CentOS8.2 and it has no display resolution problem.
