Yeah, the EX3212 is both cheap and obsolete, but I saw something on one that I can't explain after reading the manual, and if the client replaces it they'll just drop in an exact substitute. A local school has called on me to hang three of them. This is a real budget install -- they're going to use whiteboards as screens, despite the horrible hot spot. They're used to having that with zero budget for the screen. They already have been doing this since they bought the projectors and started using them on portable carts.

On to the issue: When I was there, I saw an image with the lens 109" from the screen that was 58" high and appeared to be a 9:16 image. That is, it was higher than wide. It was a VGA image from a workstation. Sorry I don't have more product details.

Checking online at Epson, an image 58" high should be possible with the lens between 129" and 210" from the screen. It's at 109."

The odd thing, that's probably a coincidence that's leading me to see unicorns, is that if the image were 58" wide instead of high, then the lens to screen distance could be between 80" and 131." The actual distance I saw is near the center of that.

Of course, that would require rotating the chip inside the projector by 90 degrees so I'd have an image that we normally think of as 58" wide, but would then be 58" high. I can't find any way to do this in the manual. I'm also not familiar with computer signals that would present this way, as though they were 9:16 (or so) images.

Can someone tell me what's going on here?

What is the native resolution of the projector and what was the source's resolution setting?

I didn't realize how much information I did not collect on my short visit to the site. I'll get the info, and maybe an explanation of the image, from the director when I visit again this week.

I also missed the manner of zooming and thought it wouldn't zoom, but the manual made that clear. And anyway, are there any projectors that don't zoom?

Not being able to zoom a projector would make the process of placement incredibly in-flexible and I don't know of any that don't.

Maybe you could photograph what you see and post it here. Is it distorted, or normal-looking but lacking correct aspect?

I'll definitely get some pictures when I go out there again some time this week. The image I saw is normal looking, by which I mean the lettering looks like a regular font and nothing is stretched all to hell. It totally lacks correct aspect unless you were to take a 16:9 and rotate it 90 degrees.

I've never even glanced at what it takes to put video into portrait mode, for instance for the desktop setups where you've got a super amount of image area by having three monitors in portrait mode to your left, front and right. Could that be involved?
