The logo has been adjusted to make the G's stroke match with the T to flow better, detaching it from the original TnaG style. Despite this logo no longer being used on-air by TG4, it can still be seen where it is impossible to use the new logos, e.g. plain white backgrounds and TV guides.
In 2017 the logo was made translucent. Idents used the previous logo until 1 February 2021
