mobile menu resolution

HelloI have the following problem with the menu, as you can see in the attached image.The problem is that if the screen is larger than 767px the menu does not appear with mobile version currently there are phones that have larger screens and when placing the phone horizontally is the menu the way I attach and not with the mobile format that would have to be.It is a question of being able to increase the size so that it continues to be taught in a mobile way, for example in resolutions of 800px wide by "x" px in height.
