When SDO was launched TVs were displaying 720p resolution. In the five years since we have seen TV screens at 1080p and now UltraHD (3840 pixels by 2160 pixels.) This means we can show half of the Sun in full SDO resolution on commercially available screens. As a result, NASA has released a new of 4k ultra-HD movies of SDO imagery. These are also on YouTube. But to get the full impact of the UltraHD resolution you need to download the movies from SVS website.
The SDO webpage also has a list of UltraHD movies. We are planning to start releasing daily UltraHD movies.
If only UltraHD allowed us to show the entire disk of the Sun at the native resolution of the SDO imagers! But that must await the next generation of screens.
