Oh Milt, what am I going to do with you?! Laptop's HDMI connectors are almost always an output with a resolution depending on the maximum the video system supports. It also send a stereo or surround sound sound signal to whatever is connected to the other end. A couple of things to check: the maximum resolution your video system in the laptop will send, what type of sound will be sent I.E. stereo or surround, if you decide to get a monitor such as a VIZIO make sure it supports an external "monitor" and it will say that on the outer box.

For example one of the monitors at the college I was teaching at could not support my video output and had a wide back area around the screen display, another one was fine and filled the whole screen. Since I am going through cancer treatment again I have decided to fully retire except for things link this.......
