I posted this already in the Activboard Forum, but I was not able to get any answers. Please excuse my lengthy post, but I'm trying to give as much information as I can. This really has me stumped. I'd really appreciate any help I could get! (Case 00421382)
Here is my post:
Over the summer, I upgraded the operating system on my MacBook Air (13") to Mavericks (OS 10.9.4). When I returned to school and plugged in my connected the projector to my laptop, the image no longer fills the screen on my board. I made sure my display was set at 1280 X 800. I also made sure the projector screen aspect ratio was set at 16:10. The product code on my board is ABV387PRO. Can you please help? I attached pictures of the display.
I tried changing the projector to the normal, true and full settings, and here's what I got:
Normal:
True:
Full:
I tried the "Auto PC" button, and that did not work. I called Technical Support, and they suggested that I try running a different VGA cable directly from my projector to my computer (bypassing the box). No luck there either.
Any other suggestions?
