Android Chrome Centering Unit

I'm having a weird problem displaying my webpage on mobile Chrome. I have a horizontal block and it just displays on desktop Chrome, but on mobile Chrome it attaches to the left border of the page.

After some research, I realized that there is a mobile “viewport” that is different from the screen size. Thus, the task is not just to focus.

The simplified markup that I use:

<body>
    <div class="block">
    </div>
</body>

And CSS:

body {
    width: 100%;
    margin: 0;
}
.block {
    position: relative;
    width: 1024px;
    height: 768px;
    background-color: red;
    top: 44px;
    margin: auto;
}

I also tried to center the block using:

left: 50%;
margin-left: -512px;
position: absolute;

But it has the same effect. I also tried adding metadata to the viewport:

<meta name="viewport" content="width=device-width, initial-scale=1">

. 1920x1080, ~ 1200 , " " 640 , , - .

- (1200 ) , . " " ... ( , , ).
