Creating a 5k res site

Are there any ways to create a site that accommodates a 5k resolution? Im creating a site where I originally started off with the normal width that the default offers for desktop. But when opened on a 5k resolution monitor, everything becomes super tiny. Shouldn’t the browser be able to scale it up to look the same as a desktop of 1920 x1080?

I’ve had problems with breakpoints as I’ve had to go into every single break point to manually configure each object. I think it is somewhat inefficent to work like this.

Has anyone found a way to circumvent such, require less break points, and make their site look the same as it would on a 1920 res?
