An HDMI extender won’t let you miss any detail in your high-definition picture.

The manufacturer equipped the devices with overheat protection and added large heat-dissipation holes to the bodies that prevent the extender from getting too hot and shutting down. A stand-alone type HDMI extender typically has a transmitter and a receiver and a DC power input on each unit, having sufficient power to carry the signal(s) for a relatively long distance. It can also use different transmission mediums to achieve different distances. For regular network cables, the distance can be 100M. On the other hand, the distance can be up to 60KM using a single-mode fiber cable. Dongle design allows you to directly connect to an HDMI source and an HDMI display, the main difference between the dongle and stand-alone design in extenders is you won't need another HDMI cable to connect to the extender and source/display.
