9 x 9 screen resolution help please

[ATROVARIOUS]

I have a 9 by 9 screen at my office and I'm having a hard time filling the screen for FS1 no matter what I try.
Any tips for a square projection?
Interestingly enough, when I was temporarily using a laptop (bottom picture) I was able to get much more of the screen filled.

Go into projector menu and find the setting for aspect ratio. Change the ratio to 4:3.

Make sure screen resolution is set to 1080p under display settings on your computer.

Ps you never going to get it to fill all 9x9 . Best you can do with A 9x9 is 96x72 inches there is no projector that I know of that does a 1:1 aspect ratio. If you want to fill the entire screen you would need a 12x9 screen.

I thought someone said that if you have the nvidia software you can make your own settings to fill any size screen. I've never done, but it has been mentioned.

Then that's something new to me I would love to find out how.

Trickle007 I think if you search nvidia you might find the post that describes it.

In the Nvidia control panel you can define a custom resolution. That is what I do to get 1920x1200 resolution to my Benq Ht2150ST. Not sure if you define something like 1080x1080 wether that would fill a square screen or not. Suppose you could use projector central calculator 1:1 resolution to try to predict.

I've tried the custom, it works to an extent with your desktop but then if you go to full screen with FS1 you have to revert to 4:3 at best.
Below is 1600:1200 which isn't bad. I'm still working on it.

[mmcfadin]

1600:1200 is a 4:3 ratio which is why it doesn't fill the height. Have you tried a square ration where pixels # are equal for both width and height?

I also have a 9x9 screen, I am interested if you have solved your problem or not. I have not purchased a projector.

The BenQ TH671ST, and most other BenQ projectors, when combined with a PC with an Nvidia graphics card, can easily project a square aspect ratio by creating a custom resolution of 1080x1080 in the Nvidia Control Panel and selecting it in the Windows Display Setting, while leaving the projector set to "Auto" resolution. Some software, like FR1, may not support a square aspect ratio, but most do. There are other reasons to like this projector, which I go into at https://store.gunghogolf.com/BenQ-TH...NEW-p265749740
