I own the EH460ST as part of my own build. I have the computer pushing out duplicate images to the TV and to the projector screen. Even though this is a short throw projector, I am not sure I am taking advantage of the full capacity of the projector.
The screen is 6x7 and the projector is 4.5 feet away. I would actually like to get closer. I went to my computer settings and used the NVIDIA to resize, but it keeps showing me it's maxed out for height. The manufacturer website settings says I should only have to be 3 feet away to get 6' high and 6'10" wide. If I get that close, I'm not close to that. Wondering if anybody knows what I might be doing wrong because the instruction manual gives diffrent layouts, but dosen't explain the settings to get to those layouts.

Any help is appreciated.

The projector details page lists the native resolution of this projector as 1920x1080. This is what you should set your display resolution to. It should not be something custom, it should not be higher, it should not be lower. Make SURE your computer is pushing out 1920x1080 resolution ONLY to the projector.

There are tons of videos online that tell you how to connect external monitors to your laptop. A projector is nothing more than a external monitor.

Your screen is some oddball aspect ratio. So, you either fill the 7' width, or you fill the 6' height and have the edges of the image fall off the sides of your screen. That's how all fixed aspect ratios work.

So, with a 6' (72") screen height, to fill it top to bottom, you would have the lens to screen distance 5'4" away. I'm not sure where you go 3 feet away, or even 4.5 feet away. That is absolutely NOT what the Throw Distance Calculator says in any way...

Thank you for the response.
My native resoultion I am using is 1920 x 1080. Setup for both the projector and computer so they match. I have connected and watched videos on how to do this, but I just wasnt getting the height results.
The manual says, when I am 5.08 feet away, I should get a height of 5.72. Right now I am sitting at 5'1" and the height is 4.8 inch high. So I'm a for off.
I am getting plenty of width and am able to resize with Nvidia.

If you are using any digital correction like keystone or anything else, it will impact the height you will get from any listed distances. Make sure all keystone or digital correction is turned off in the projector, that will allow you to get the full image height.
