Our local photo club is using a new Optoma ZW300UST projector to display images at our meetings. The projector was bought by the senior center where we meet. We have traditionally copied our images onto USB thumb drives and inserted them into the USB port of a digital projector, but this one has problems reading the files properly when they have been copied from a Mac.
It always displays a number of blank images at the beginning which seem to be “hidden” files created on the Apple device with filenames that duplicate the actual image filenames. We can scroll past the blanks, but sometimes the projector won’t recognize most of the images on the drive at all. We’ve found that it makes no difference how the drive was initialized, or on whether it was initialized on a Windows or Mac computer. The problem arises only when we copy images from a Mac to the drive.
All of the people who are involved in this process are Mac users without easy access to a Windows computer to do this job.
The dealer has talked about this problem with Optoma at length, and they are disinclined to fix the incompatibility in the firmware, arguing that most people use Windows (and most users of their projector are not using still images on thumb drives as sources).
I know this is a long shot, but is there any way out there that could suggest a work-around that would allow us to continue using our Macs?
