Mr. Atoz
I want to give a presentation with Keynote on my Mac Book Pro.
I also have an Epson powerlite s6 projector.
Will they work together?
I don't have them both here with me so I can't know for sure.
Answer
I have given presentations on a Mac with fifty different projectors in the past six years. There is no projector that is a "No-Macs" projector. Almost all projectors are "old technology" VGA connection, because most PC makers are too cheap to change to modern Mini DisplayPort. You will need an adapter and a VGA cable (probably M-M). Most schools and hotels have VGA cables for this, but I travel with both M-M and M-F cables as a belt-and-suspenders approach.
If you are going to a remote location, ask if their sound system is working. I estimate 20% of systems I have needed to use had out-of-order sound on their consoles, so I also travel with a pair of small speakers to connect directly to the computer. A desperation solution is to hold the mic near the computer's speaker.
Now here is where I jump on your case for not telling what you have. The early MacBook Pro had DVI out. All recent ones have Mini DisplayPort out, because it can send video and sound out one port. Tell what you have, and I'll tell what adapter you need.
If you want to use "Mirroring", set the resolution to "1024 x 768 (stretched)", because almost all projectors are old nearly-square aspect ratio. You should also create your presentation in this old-school aspect ratio. Yeah, that's right-- nothing much is up-to-date in PC-land.
Sometimes the projector does not respond to the connection, so you will arrive ten minutes early to try it. The most reliable approach is to turn on the computer first, connect all cables, and after the system is fully loaded, turn on the projector, and if you are connecting through a console, immediately check that the switch is set to "laptop" and not to an under-desk tower. If you have a console with such a switching setup, any delay in switching may get the projector to respond to the tower connection,and that may lead it to fail to recognize the MacBook Pro. If that happens, turn the projector off, wait three minutes for the lamp protection timer, and turn it back on. Occasionally even that isn't enough, so always have the System Preferences set to "Show Displays in menu bar", and you will then click the displays icon to choose "Detect Displays".
On rare occasions, you may find a projector will not notice your OS X-generated signal at all, even after restarting both projector and computer. The quickest fix is to boot to Windows, all is well, and then reboot in OS X, all is well. That's the main reason I have Windows installed in Boot Camp. VM Windows won't help for this. In all my university classrooms, there is a Windows box under the console, so I don't need the Boot Camp setup. I just turn on the tower, make the connection to the projector, and then press the button to switch to "laptop".
