Both our projectors are VGA rather than HDMI. More laptops only have HDMI outputs. There is an HDMI<->VGA cable knocking around, but it doesn't appear to work (didn't on either my or @goatchurchprime's laptops)
We should either get an adapter or maybe even a new projector that's HDMI?
I've had trouble with HDMI->VGA cables with digital to analog (I think)
If that proves to be an issue another option might be a USB VGA adapter perhaps
Happy to look for a new projector if someone gives me a) an idea of spec, and b) a rough budget.
Never having dealt with projectors before, I'd be a bit lost without a little guidance.
Historical scavenged from old doeswiki here: https://github.com/DoESLiverpool/wiki/wiki/AV-setup-in-Dinky. Delete that page when done with it and in-line info about the projector (brand, capabilities, etc) either in the Rooms#Dinky page or from the Equipment page.
The adaptor cable posted by @DefProc has been ordered. It should be here by the end of the week.
