Spoke to the people who supplied my 21" monitor today. They claim the monitor was tested and was in full working order - missing the point of my complaint entirely that it although it did work, it produced a dull and non-vibrant image.
I even tried a second SVGA cable yesterday which didnt seem to work at all.

However they did promise I could exchange for another of my choice (may have to trek it down to Thurrock myself just to test things and ensure all is okay) however they have run out of Black monitors and only have beige ones left *dang!*.

Another bit of Arcade-related news, I have found out that it is indeed possible to run Snk Vs Capcom: Chaos on a hacked version of Mame.
Excellent news! I will be working on adding this to my exisiting Mame setup tonight when I get back from the Gym.
