Abstract: Methods and systems for content resolution adjustment for passive display devices are described herein. Passive display devices such as a passive magnifying device (e.g., a screen magnifier) or a projector (e.g., a built-in mobile phone projector) are useful in enlarging photos, documents, videos, etc. for view for small-sized small-screen device screens. However, optimal content resolution for the small-screen device screens may not be optimal for the passive display devices. Particularly, when a small-screen device receives content from a remote computing device, the initial content resolution may not be optimal even for the small-screen device screen because of low transmission speed and/or low bandwidth of a connection with an original data source. Content resolution adjustment is provided in this disclosure by determining distance between the passive display device and the small-screen device, calculating magnification ratio for the passive display device, and adjusting the content resolution based on the calculated magnification ratio.
