Five will launch today in HD, with both Virgin Media and Sky showing the latest high-definition channel.
Five HD will be a simulcast of Five's terrestrial offering, bringing a host of top shows (and a lot of not-so top ones) to the home in high definition.
Cable and Sky customers will be able to view the channel, but not Freeview HD viewers - with Five famously told that it would not be able to keep its slot on the platform.
Programs to be shown in HD include The Mentalist, Grey's Anatomy, Law & Order, and sport including cricket and Europa League football.
Charles Constable, Five's Director of Strategy, said: "We broadcast so many high quality series shot in HD, such as Don't Stop Believing and our line-up of great US dramas, so our schedule is really suited to fantastic picture quality.
"Five HD is a great addition to our channel portfolio."
The channel will launch on 171 on Sky (currently showing a placeholder) and 150 on Virgin Media.
Virgin also announced that it will be bringing two time-shifted channels for Five channels, Fiver +1 and Five USA +1 will be on channels 152 and 154 respectively.
