We just purchased this projector and just learning how to use the Wireless feature. We have not used it on a desktop but on a phone, a tablet and working on using the laptop. Epson claims you can go 50 feet away, I think is the distance and with a phone we have been about 40 feet away. Also we have only accomplished connections using the Epson App. It has beautiful color and brightness and I can say that connecting up the App and projector is in no way as easy to do as they say. Sorry I was not more help but this is a great projector and only review complaint was a louder than most fan noise and they are spot on as it is louder than I have ever heard a projector fan.
