Not right now.
Hydrow does not have any physical connectors which would allow you to connect it to an external screen. There is no video out, or A/V out jack, on the hardware. The software also does not have the ability to share or cast the screen to another display. (airplay, Chromcast etc.)
Some variety of video casting/sharing could potentially be implemented on Hydrow in the future. But for now we don't have any specific plans to do so.
