Image not fitting screen, projector or computer??

[Solstice72]

I generally try to run the golf club in 4k but I want to try native graphical settings for a second. In the 1980 X 1200 Windows resolution it doesn't fill the screen. How do I fix that here are some pictures. In one of them notice the output signal is still 4K is that the issue and how do I change that then ?

Projector set to 16:10? If not change it to 16:10. If it’s set to 16:9 I think it will do that but not 100% sure

The projector is native 1610 but the screen is a 16:9 unfortunately. It fits perfectly in 4k but I don't get the shrinkage on the lower resolution

You are running a 16:10 resolution and setting the projector to 16:9. You should try to match the two I think. So either switch to 1920x1080 (1080p and a 16:9 resolution) or set the projector to 16:10 and run 1920x1200.

That makes sense, I think? So 3840 x 2160 is a 16 x 9? Because that fits perfectly. But maybe that's because I did other alterations to make it fit I can't remember.

All right let me play around with the aspect ratios.
I'm confused though in my picture why the output Source still says it's 3840 x 2160? What is it talking about? I have the Nvidia and windows resolution at 1200p.

That's why I was wondering if that was the problem

[Stingreye]

Yes exactly. 3840/16*9= 2160 so 16:9.

1920/16*9 =1200. So 16:10.

Its ratio of hieght and width.
