I'm not going to have the opportunity of doing that with projectors I'll be using. Looking online, I'd really need to know all of the projector's technical specs, or spend a lot of time finding working settings by trial and error, to have much hope of getting it working properly. It detected the projector and mirrored/extended the display, but the resolution options remained limited.Īs for SwitchResX, its default 1024x768 resolution worked, but when I tried to create a custom 1400x1050 resolution it didn't display correctly and then crashed. SwitchResX should be able to do this, that is what it was created for. Have you actually tried to connect one of the projectors? And what protocol are you using for the connection, ie, DVI, DP, HDMI, VGA? At the back of my head there is the notion that depending on the protocol, the monitor can actually broadcast its resolution to the computer.Īnd I would try to better understand why SwitchResX is not able to do what it is supposed to do. I thought someone else here might have encountered this limitation and found an alternative way to work around it. I thought I'd try asking here as 4:3 ratio projectors still seem common for photographic use, as opposed to home theatre. It'd certainly be an extra expense I didn't expect when buying a MacBook rather than a cheaper Windows laptop. Windows is looking like the only reliable option to use my Macbook with those projectors, but obviously I'd rather not have to buy an extra copy of Windows and MS Office if it's possible to get the job done with Mac OS X and Keynote. For image quality I'd much rather use the projector's native resolution, and I haven't had much luck creating a working custom resolution in SwitchResX (I don't know all the technical details of the projectors I'll be using). I've asked this question on a couple of Mac forums, and the suggestions offered were to either to use 720p 16:9, try a utility called SwitchResX, or run Windows in Bootcamp. The problem is that both my workplace and my camera club use SXGA+ projectors with a native resolution of 1400x1050, and that's a resolution that Mac OS X doesn't seem to support. I've recently bought a MacBook Pro 15" and want to use it to show some presentations and AVs.
