Recently, I have got an image designed to display for my header and this is the way how I hide my default title and tagline without affecting Google index.
Before

After

Search the following code or something like this in header.php

<h1 id="title"><a href="<?php echo get_settings('home'); ?>
/">......</a></h1>

Add in the following code to the same row before … </h1>

<span style="margin-left: -3000px;">

Same for tagline or description in header.php

<p class="description">......</p>

Add in the following code

<span style="margin-left: -3000px;">

The benefit by moving your title and tagline to -3000px: Google and other web crawlers will still index on your blog whereby in your 1280 highest resolution monitor would be invisible to see it. And yes, you can see it only if you have 3000 and higher resolution monitor.

If you have a better solution for this, please let me know. Thank you.
