RPI to duplicate laptop screen over network?

Sun Aug 12, 2012 5:38 pm

Hi guys,

Is there anyway for a RPI to duplicate the screen of a laptop via network connection?

I ask because I know someone with a laptop with no HDMI out and he wants to be able to quickly show things on his TV. I was thinking some software on a Pi that could just show the laptop display and have that plugged into his TV.

Any suggestions?

Thanks

vnc.

install a vncserver on his laptop and a vncviewer on his raspi. http://www.tightvnc.com/ will work.
he could also probably use rdp as well but vnc is probably quicker and easier (at least as i'm concerned others may disagree)

NEVER.

Really ,for that i would invest in a h.264 hardware screengrabber. And THEN you'll have to stream it. I suppose solutions exist ranging from 300 to thousands of dollars.
(Of course yo can do it in software , thats what a 1 KW power-supply and the newest i26 thirteen-core processors are made for.)

What Latency do you expect ?

Does the TV have a composite video jack? Then you can plug the Pi in directly.

The TV has HDMI.

I just want a way for the laptop to display on the TV via a Raspberry Pi.

Okay ,
just try Remmina on the Pi , and enable RDP (desktop sharing) on the Laptop.

Lets see how this will turn out.
