— Astro (@astroonline) January 23, 2020 Through a response to our query, Astro has also further clarified that all 51 matches of Euro 2020 can indeed be viewed in 4K; not just selected matches. However, the company not able to confirm at this stage whether there will be dedicated 4K channels for the event since all of Astro 4K contents are currently being shown only on a single channel which is the Astro UHD channel 780.
That being said, given that some of the matches will take place at the same time especially in the early stages of tournament, dedicated channels are a must if Astro want to show every single Euro 2020 matches in 4K. Hence, expect additional announcements from Astro regarding Euro 2020 coming your way soon.
