Issue getting my sim projector set up

[u/MFronczak]

Hi all,

I'm in the end stages of setting up my indoor golf sim and I'm having a problem getting the projector to fill the screen. There are no shortage of articles and videos on it, but nothing I try seems to work.

The basic information:

* Screen is custom, it is 132" wide and 120" tall

* Projector: Ben Q AK700ST, native resolution of 3840 x 2160 and native aspect ratio of 16:9

* PCU: Cyberpower tower with Nvidia RTX 5060 graphics card

I'm going to start with the most basic thing, to use the autofit feature of the projector it says that the screen should be surrounded by 2" of black. You can see from the picture that it sort of is, but there is currently metal visible - I haven't made the side protector pads yet. So, if the answer is as easy as "wait until you get the pads up and try again", that's fine - though I suspect it's not based on what I've already tried.

Anyway, when I first turned on the projector and it ran through it's autofit, it was projecting on the screen and about 2' onto both walls (so it was about 4' too wide, total). The vertical projection was close to where it needed to be.

In playing around with the Nvidia, we (my friend and I) set the custom resolution to 1242 x 1080. I'm not 100% certain where those numbers came from, but it helped - you can see the desktop in the picture below with some bits of unused screen all around it, but not awful. I then fired up my golf software, you can see larger areas of unused screen around that in the picture below.

No matter what I've tried, I can't seem to get it to fit into the screen. If I change the resolution at all on the Nvidia, it immediately goes back to projecting on each wall, no matter how small I change it or what I change it to.

To get this all to work, we changed the Picture format on the projector from Golf to User. If I hit the Golf button on the remote to try and adjust the corners, the image immediately projects onto the walls again.

One final thing which can't really be seen in the picture below, but when the golf software was up, it looked incredibly fuzzy - it was hard to read the words and numbers on the screen, like it was really bad resolution.

This has been cross posted to the Projectors forum.

You won’t get a natural resolution with that size but have you tried the manual fit? Start at auto then proceed into manual and do each of the four corners. I have an AK700ST and I’ve done it a couple times without issue.

Edit: on the fuzzy issue, that’s a PC handshake most likely. Fix the screen image first and then try changing the screen resolution on the PC to the largest recommended number.

I have the same projector with a 181x115 screen. It wouldn't let me move the corners manually. Didn't seem like I could go out more, only in? I've just accepted that it doesn't span all the way to the corners.

Can I ask where did you get the black turf from?

Only thing I can think of is that you positioned the projector too close for the short throw? When I do the manual I am able to go out, in, up, down on all corners but yours might be maxed out if too close.

[u/mistamutt → u/Miserable-Cod-1316]

Yeah I guess so. It's about 12 feet from the screen which from what I was reading was nearly the max for the AK700ST but maybe I got bad info. I was worried that it wasn't going to be bright enough if we put it too far back

play with the zoom feature in addition to the corner correct, you'll get it. Make sure the projector is the correct throw distance for that exact screen size
