4k is the most common resolution for videos today. This resolution is equal to 2160 x 1200 (the highest resolution that you’d expect your device to display after turning down your resolution by 200%). That is enough to show you almost all of the screen in the video.
Why is your device limited by 1080p? 1080p is the standard resolution of your device, so you can’t watch 720p from your phone without the upgrade. The new 4k resolution may be enough for people looking for a video quality that allows them to watch the entire screen at once, but that still won’t meet the full potential of the display on your phone. The resolution limits the size of your image. If you view content on your phone in full-screen mode, it can’t accommodate 4k video at a reasonable frame rate.
What resolutions does your device support? Your device is limited by two resolutions. 720p is the largest resolution for videos at 480 x 2160 and 640 x 360 pixels. These resolutions are compatible with phones, tablets and computers. The phone may support an additional resolution that is more compatible with HDTVs and monitors.
How important are pixel counts to video display quality? Pixels are the basic unit of resolution. Without enough pixels, the image looks flat. There are few ways around pixel counts. One is to create a small pixel. As your resolution rises, your display gets smaller, but the smaller your resolution is, the higher the number of pixel rows in your display. Some displays get up to eight rows of pixels. Some phones, like the Motorola Xoom or the Xperia S, are made with four rows of five pixels in a 5-inch screen.
How important is the aspect ratio of a video? The ratio of a video is important. If the video is displayed in fullscreen mode, the ratio should be an obvious 1:1 and all video should be presented at the same aspect ratio. Some people like to view videos through their phones’ aspect ratios (one being the ratio of the width and height of the device; the other being the ratio of the height to the width of the display). You can tell the width of a screen in its viewfinder by looking at the top and bottom. If the video is displayed at 1:1 resolution, the screen is wide. For one pixel in that aspect ratio of the horizontal and vertical line, the width of a pixel is equal to the image width in pixels. However, with many applications (for example, in games),
