Our Verdict
BenQ TK700STi
BenQ X3100i
The BenQ X3100i is better than the BenQ TK700STi. They're both gaming projectors, but the X3100i supports 4k @ 60Hz, 1440p @ 120Hz, and 1080p @ 240Hz, while the TK700STi is limited to 4k @ 60Hz and 1080p @ 240Hz. The TK700STi also comes with the older QS01 streaming dongle, which lacks many of the advanced features of the QS02 dongle included with the X3100i, although you can purchase the dongle on its own to install in the TK700STi. Otherwise, the BenQ X3100i offers superior image quality, with better brightness, contrast, accuracy, and colors.
