Question

Display laptop screen onto another laptop wirelessly

May 6, 2014 3:38PM PDT

I am a teacher who has been given an old projector with no wireless capabilities (dongle doesn't work). But I have a school provided laptop and my personal 2-in-1 laptop.

I want to be able to walk around my laptop, while still projecting. Is there a way I can wirelessly have the school laptop display my personal laptop's screen wirelessly, so that I can project the screen for the classroom?

Or, do you have any other suggestions (other than buying a new projector)?

Why not attach a wireless mouse and pointer device, not a regular wireless mouse but a dedicated presentation type device, to your school lap top which will be connected to the projector.

Now you can wander around the room and control what is on the laptop screen with the device.

A device like one of these, the result of a quick search:

that help?

Want to take advantage of my 2-in-1
May 6, 2014 11:28PM PDT

I already use a wireless mouse, but I wanted to take advantage of my 2-in-1 and be able to use OneNote to have them physically draw on the tablet for assessments, or be able to type their responses if I were to call on them, rather than have them physically get up to the front of the class (my classes are far too shy). But thanks for the suggestion!

I don't see enough detail here to nail it down but about a second laptop (even a netbook will do or cheap laptop woot.com) and use one of the usual mirror apps?

Now before you ditch the second laptop, consider that wireless HDMI can cost as much.

Miracast can be fiddly so be sure to test it all before you start the class.

Ad-Hoc network
May 7, 2014 2:34AM PDT

Basically, a mini-network with those PCs knowing each other being the network. Google ad-hoc network for the details. All this becomes a real PITA if anything is unique and already just having the network is one. I suggest you make the laptop the primary and then the tablet the ext. device that attaches to the network. If you have any network setup already on the laptop be sure to back-up or safeguard its setting or note them. Just in case something goes awry. Further, any security depends on what you deem necessary, but you want this to be as open as possible until you fine tune that aspect of it. I offer that because any other wifi device like a android tablet could sneak in(students) and cause some havoc. I can't offer anything more other than the idea and I know it can work, as its the fallback for many traveling sales people if their setup fails.
