The 8-Bit Guy on Youtube made a great video series on character LCD screens and how to run them. In the first video he shows how to drive one manually using just switches: link to this video In parts 2 and 3 he shows two ways how to drive them with a C64: link link

If you don't need actual HDMI and a regular monitor then there are other solutions which are more like what you describe: Firstly there are simple character LCDs which all have a standardized and simple electrical interface1 for sending ASCII characters and control codes. Then there are bit-addressable colour displays that let you send drawing commands, eg: 2 3 4 1 link to this video 2 link 3 link 4 link
