      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: 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 interface[1] 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] this video [2] [LINK] [3] [LINK] [4] [LINK]
