portrait orientation screens
« on: August 25, 2023, 08:06:39 PM »

Part of a set, but was wondering if it's ok to run projectors on their side? -or do you aim them normally and crop the image (wasting over 2/3 of it)

It's rear projection so at least audience won't see whatever crazy scheme is invented to accomplish this.

First thing I'd check is if the projector is rated for sideways orientation, as some are but not all.  If the projector is rated for it, go for it.  I think I've done this once, long ago, as I remember talking with a few projector manufacturers about this exact topic.

+1. Some projectors are perfectly happy doing this, some are really not, and it's basically model-specific.

Yup, depends on the projector.  Some are perfectly OK flying sideways, others will have heat flow issues and you can destroy them quickly.

The only other issue is now you're scanning vertically instead of horizontally. This may make videos look slightly different, although most won't notice.

Sorry guys, browser tab error -I thought I was posting in the AV forum -I normally don't want to pollute our audio forums with vidiocy.

I will probably zoom & crop because now there's talk of some imag on those portrait screens and I don't want to have to deal with sideways cameras -especially when they will also have time on the main normal landscape screen.
Is there a simple device that can rotate the picture from the cams?  (we will be using a BMD constellation 2M/E switcher)
-because I still like the idea of projecting sideways at full resolution
And I won't have to have the projectors as far back to fill those screens.

-regarding the scanning issue, I didn't think there was raster type scanning going on anymore with pixel-based projectors?  Thought it was more GPU-based bit-mapping?
It looks fine on a large 85" TV so wouldn't think any different on a projector.

Thanks for all the advise, I will thoroughly explore the heat flow issues and upgrade to laser units if needed.

Iíve done this before with PJs that were rated for use on their sides.  The screens were also hung in portrait.  It was a big corporate meeting with a 60í wide center screen flanked by two portrait hung screens.  I believe they put imag on the side screens.  No idea what video processing they used to accomplish the crop - I was just assistant projectionist on the gig and thankfully didnít have to worry about the content.
