If you want information, e.g., the manufacturer, model, serial number, maximum resolution, display modes, etc. on a monitor connected to a Microsoft Windows system, you can use the free DumpEDID utility created by Nir Sofer of NirSoft. It's a command-line interface (CLI) utility, so you will need to run it from a command prompt. There's no installation process needed; you can extract the program from the downloaded zip file and then run it. Below is output from the program showing information for an HP S2031 monitor (the manufacturer and model number apear in the Monitor Name line) attached to a system running Windows 10.
