Logo Different Sizes on Mac vs PC

Hi there, 

URL: www.nocturnallegal.com

On my mac, the logo for my website was too small and the native slider in the Site Style settings did nothing. I entered this code: 

Header-branding-logo {
    max-width: 2000px;
}

.Header-branding-logo {
    width: 100%;

Which made it appear the size I wanted on my mac. Unfortunately, if you visit my website on a PC, the logo is massive and showing the true 2000px size. I'm not sure what to do at this point. I either have a massive logo on a PC and a great logo on a mac or a miniature one on a mac and a great logo size on a pc and there's no good in-between. Help! 

Edit your code to this

@media screen and (min-width:2000px) {
.Header-branding-logo {
    max-width: 2000px;
}

.Header-branding-logo {
    width: 100%;
}
}
