Hello all,
Question about using micro HDMI-SDI (and micro SDI-HDMI) converters to push signals to XGA (1024 x 768) projectors.
Background: installed new XGA projectors (2) in my church this morning. Connected our existing VGA cables, but also ran SDI and installed BMD micro converters.
It seems like these converters always want to push a widescreen image. When I play a widescreen video that's fine (I get the black bars on the top and bottom of the screen as expected). When I attempt to play something that's 4:3 (video, older PowerPoint slides) I get black bars on all 4 sides of my image, rather than having the image fill the screen. My projectors always report that they're receiving a 1080p signal, regardless of what I set my PC video card to output.
Given that our screens and our projectors have native 4:3 resolutions, is it possible to configure any of the BMD devices to always send 1024x768 resolution? Is there another piece of the puzzle that I'm missing?
Here's my basic signal route:
2 laptops, both connected by HDMI into a BMD micro HDMI-SDI converter.
SDI cable to a switch
SDI cable out to projector 1 (BMD micro SDI-HDMI converter)
SDI cable from projector 1 (BMD micro SDI-HDMI converter loop out) to projector 2 (BMD micro SDI-HMDI converter)
Thank you for any help you can give me.
Best regards,
Eric
