Three monitors. The first one is a small, white, CRT monochrome screen with a built in radio, no problems notices with it. The second one is a Sanyo ViZon Flat-Panel LCD TV with a classic 4:3 aspect ratio, using a composite and multiple other types of similar connections with no problems noticed. The third one is a Dell CRT Computer Monitor with a vga connection, no problems with the internal parts, the only noticeable problem is a decent bit of plastic off of the vga connections plastic. It won’t affect anything other than possibly a slight bit of trouble for screwing it in, though personally I haven’t found any trouble from it. Specifically though, it is a Dell E773s.
