<p>Thanks much to both of you. Maximizing the performance and compatibility among computer, graphics card, photo editing software, monitor, cable connectors, etc. etc. is not easy, and the one party that might seem able to help me sort it out (Dell) has no technical support worthy of the name. But my existing rig offers excellent performance, excellent results photographically and terrific printed images that closely resemble what I see on the screen. So I'm declaring victory. Thanks again for your help.<br>
