Can I use a wi-fi dongle so that in can connect speakers wirelessly. is there any way to use Bluetooth speakers with this model?

Simple answer is yes. I use a Wi-Fi dongle connected to my blue tooth speakers and there is no lag. Hope that helps.

Could i upgrade from benq 1080p projector th671st to 4k tk700sti directly without changing ceiling mount?

Hi there, thank you for your question on our TK700STi gaming projector. Please be informed the position of the ceiling mount would have to be changed if you would like to upgrade from TH671ST to TK700STi. For further detail, you can use our “BenQ Projection Calculator” to calculate the accurate throw distance for your preferred projection size. If you have further questions regarding the TK700STi gaming projector, please feel free to contact us using the Online Chat service on our official website, and our customer care specialist will be more than happy to assist you. Thank you! Warm Regards, BenQ Customer Care

What size could this project from roughly 2.4m?

I checked and from 2.5 meters away from a 44cm table, I can get a 101inch screen

I have a 120 inch screen and the distance to the screen is 3.3m will this projector fill the screen

YES, with a "But". The distance from the screen for 120" needs to be between 1.833M and 2.205M (The zoom range). Optimum distance is 2.019M. If you download the manual, there's a handy diagram on Page 13 that helps you calculate the projection distance from the screen. If you are working with a fixed distance of 3.3M and can't get closer to the screen you will then have a problem as the image will be too large.
