The Rollei Innocube IC200T has a maximum resolution of VGA (640x480). That's 70% less resolution than a WXGA (1280x800) projector, which is the most frequently found resolution. Across all projectors of a comparable spec and age to the Innocube IC200T the best resolution is DCI 4K (4096 x 2160) and the worst is nHD (640x360).
It is worth considering alternative projectors that have a resolution of VGA (640x480) including a higher Kagoo Rating™ multimedia projector such as the Genius BV180, or the Aiptek MobileCinema i55.
Data projectors with a higher resolution that might be worth considering include the Gigabyte BRIX (£111.79) (WVGA (854x480 and higher rated) and higher rated), the Viewsonic PJD2121 (SVGA (800x600 and higher rated) and higher rated), or the Hitachi CP-S240 (SVGA (800x600 and higher rated) and higher rated).
