All, I recently bought a cell with 1920 x 1080 resolution. When i search for a 1080p video in Youtube ad play it, it plays fine. However, the same video is playable in another cell with only 720p screen resolution. How can that be possible? How can we verify if the video played in youtube is just HD or Full-HD?
You tube videos while titled Full HD do not appear to be playing at that resolution. When you click the three button vertical bar on top right, you get a menu option and the central one which is a gear icon displays resolution, which is lower.
For downloaded videos, you can always check the resolution using VLC player properties listed under video track
Some cell phones like mine Honor 6 have an option to lower the screen resolution to achieve better performance and battery life. Hence, as suggested in comments, please do check the properties of resolution
