This is how I see the main menu on a full hd screen LINK

This is how I see on a retina display LINK

Hope it can help to understand the problem.
Thank you!

Thanks for your help, now it looks much better, very useful.

There is any way, also via css, to change the logo dimensions to have it a bit bigger?

Hi,
Thank’s for your reply!
I’v found a plugin for the background managment, but when i click on it, don’t open the link.
In the documentation i’v found thi FAQ: http://wordpress-advertising.com/faq/#faq/link-background-ads-not-working
They say:

If you added a background ad to your site but the link is not working it means that your theme has another full width container div above the main body. You will need to find out the ID of the specific container div and add this to the Background Container field in the shortcode editor.

If you can’t find the specific container ID please contact your Theme developer.

Thank you

Hi Adrei. I want to use the background like a normal ad space and I’m trying to use different images that can change every new user session.
Is it possible to do it? I need to insert the javascript code to evoke the right banner.

<script type=’text/javascript’><!–//<![CDATA[
var m3_u = (location.protocol==’https:’?’https://www.website.it/www/delivery/ajs.php&#8217;:’http://www.website.it/www/delivery/ajs.php&#8217;);
var m3_r = Math.floor(Math.random()*99999999999);
if (!document.MAX_used) document.MAX_used = ‘,’;
document.write (“<scr”+”ipt type=’text/javascript’ src='”+m3_u);
document.write (“?zoneid=2”);
document.write (‘&cb=’ + m3_r);
if (document.MAX_used != ‘,’) document.write (“&exclude=” + document.MAX_used);
document.write (document.charset ? ‘&charset=’+document.charset : (document.characterSet ? ‘&charset=’+document.characterSet : ”));
document.write (“&loc=” + escape(window.location));
if (document.referrer) document.write (“&referer=” + escape(document.referrer));
if (document.context) document.write (“&context=” + escape(document.context));
if (document.mmm_fo) document.write (“&mmm_fo=1”);
document.write (“‘><\/scr”+”ipt>”);
