Custom Screen Size and Custom Aspect Ratio Question

[Hawks2125]

Planning a garage simulator build using an EYEXO. The limiting dimension of the space is width (12 feet for the entire space). So I am planning on getting a 138 inch enclosure and then using a custom screen size to maximize the height within reason. This will leave me using a custom aspect ratio to completely fill the screen (will be close to 4:3 but slightly taller). I understand this is feasible by reprogramming the Nvidia GPU and setting up the project properly (BenQ LK936ST).

My two questions:

1. What would be a reasonable height to ensure that I can hit a flop shot with a 60 degree wedge and still have the ball hit the impact screen from a hitting position of 10ft from the screen. I know the trigonometry equation here, I am more so interested in others experience in real life.
2. When using a custom aspect ratio in this manner, when you set the height of the screen to match the native projector aspect ratio and then decrease the number of pixels in the width to fit, are you actually cropping the image or just resizing it? I'd obviously hate to crop out pixels and lose information.

If you have walls that define the 12ft width, i would ditch the enclosure and attach the screen directly to the walls.

I hit about 10ft from my screen and can hit my ceiling with a good flop shot. my ceiling is 10.5ft tall. You can hit closer than 10ft, but either way I would have some sort of ceiling protection.

When you set a custom resolution on the PC, you are cropping the image, however the PC will still maintain all your desktop icons and even game data are still in-tact but you are effectively losing width in the course. An alternative is to send the full resolution and set the projector to 4:3 mode and it squeezes the image inward so you don't lose any of the course. It's personal preference and wasy to try both methods. I have the same projector and set it to 4:3.

I have a golf sim business and sell all this stuff and can help save you some money. I can do custom screens as well. I've helped many people here.

Not limited by walls so I'll have to get an enclosure. So if I understand the aspect ratio issue correctly, your computer basically eliminates pixels from the width of the image, but not necessarily by just cropping the edges. So you lose pixels uniformly across the image but don't lose "field of view" if that makes sense?

[COgolfengineer]

You are losing pixels and images will be chopped. So if the golf course has a tree on the left side, when you set the custom resolution, you might not see that tree. If you have the projector set to 4:3 and send the full resolution, the projector takes the full image and squeezes it inward so you don't lose any of the image.

[COgolfengineer]

But GUI stuff like course data and player names and minimap that are typically on the sides, you don't lose any of that with either method.

interesting I need to get a 4:3 ratio out of my epson 535w i did not know I would be losing stuff. Thought about getting native 4:3 projector

[COgolfengineer]

Rlefig don't get a 4:3 projector! Very old and outdated and can be very difficult to find. Your projector might have a 4:3 picture mode and it would squeeze the image inward. You're still losing pixels but you're not cropping the image.

COgolfengineer I ended up getting an optima GT2000HDR. I will use video card for 4:3 resolution. Small 1930's garage means restricted space for projector

Well I can say as I have a 11 foot high ceiling and hitting 8 feet way from net which even my regular swing 60* wedge (not flop) will hit above my 10' screen from 8' away. So if you are 10 feet plus doing a flop shot you better have a net or foam above....lol
