I noticed the picture on my new computer monitor was a bit fussy so I bought and new LGA cable, it worked and the picture quality was awesome. Only problem is when I have the new cable in the computer just goes to a black screen when I turn it on, so I need to have the old cable in (with the fuzzy pic) when the comp starts up and change it once windows has loaded. What could be the problem? It so annoying
