Hello all, 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. I tried adding i915.alpha_support=1 in grub.cfg (https://access.redhat.com/discussions/3410491) (so that i915 fall-back driver can be used) but it was the same. The intel site only provides driver for windows. Could anyone give me some advice? Thanks for reading. Chan
