Nreal Light provides a fairly clean 1080p virtual ~115 inch screen floating at 2 meters. It's available variously outside the US. Inside the US, there's ebay with SKorea units (plus varying US Customs duties). I'm screen mirroring my laptop (as I type this, but not usually) using a usb3-from-hdmi dongle to work around issues. Assorted polish and comfort issues. Support is poor, so it's not turn-key, more hobby project.
