The Inspiron 8600 can't output the full 1920x1080 resolution image that you would need for a full, crisp picture on the Westy 42". IIRC, the max resolution output is 1280x1024, so if you have it sized on a 1:1 pixel basis, it will be sharp, but won't fill the screen. If you have the monitor scale the image to fit, it will be somewhat distorted and will become blurry. I'm afraid there really isn't anything you can do, excepter perhaps choose a different LCD monitor with a lower pixel resolution that would accomodate your laptop's capabilities. Or upgrade your laptop to a newer model with higher resolution output and preferably a DVI connection so you get an all digital link.
