Be able to increase the size of the gui screen

Hello, I propose to be able to increase the screen size of the gui, I have calculated and the max image size is 854 x 480. However, this size greatly limits me and I guess many other people. I can put this image but the problem is that it size very quickly limits the available space, that's why I propose to be able to increase the size of the gui screen to put larger images like the second image here -below

Thanks for read me
