7mate was launched on 25 September 2010 in high definition.
When Seven HD was revived on 10 May 2016, 7mate was reduced to standard definition. While Seven HD became a simulcast of Seven's main channel in Melbourne and Adelaide, it became a simulcast of 7mate in Sydney, Brisbane and Perth as "7mate HD". 7mate HD briefly became a simulcast of Seven's main channel in August 2016 in order to simulcast the Rio 2016 Olympics in high definition in all capital cities.
