HDMI graying out when plugged to external display on Catalina.

I have an issue with the hdmi display output. When I plug in the hdmi to a display the laptops display gray's out and nothing comes on the display too. The trackpad and keyboard also dosen't work. specs of my laptop are

Core i5 4310u 4GB of ram 256 GB ssd Intel hd 4400 graphics Model e5440 Company dell Mac os version 10.15.6

These are the specs of my laptop.

The usb 3.0 is showing up as 2.0

These are the problems with my hackintosh. I am a noob. I don't know how to do intel frame buffer or something like that. So can anyone help me. Thanks
