VGA splitter

A few weeks back I bought a Cintiq Wacom tablet. It turns out to function as both a tablet and a monitor. (I kind of expected it to work as simply as Graphire, but on hindsight this is of course stupid.) Since my PC has only one VGA out, I got myself:

• a VGA splitter 2/4 port VGA splitter. Model MT-2504-A. I jsut reaplized that the pack does not have a brand (unless "VGA Splitter" is a brand).
  
• a Manhattan monitor cable HD15 Male/HD15 Male. The packaging points to http://www.manhattan-products.com/index.shtml; but strangely I cannot find the product on the website.
  

They are supposed to be of good quality (I asked the store attendant) so I had high hopes. Well, it is rather disappointing. My monitor is visibly blurry now. Especially for white Arial/Verdana fonts on a colored background (a common thing in websites). I guess it's acceptable for browsing, but it's definitely not good enough for digital inking (what I hoped to do with my Cintiq).

And so that's the disappointment of today (other than the fact that Games Convention Asia does not open on Sunday, which I think very stupid).
