I recently got a new HP ink jet printer to use with my Lenovo computer and Dell monitor (older model, 1707FP). As soon as the installation software for the printer started, the monitor display went awry. What should be a white background is a gray-green. Red is gone entirely. When I press the menu button on the monitor, the display shows full colors. Otherwise, the display is messed up.
It seemed too much a coincidence not to relate this to the new software. I updated the Dell monitor driver, but that did not help. Any ideas on what to try next?
