RPI to duplicate laptop screen over network?

[MorgUK]

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)

Thanks, do you know if it will be able to do 1080p 30fps OK?

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.
