When I got a pair of progressive lenses, I encountered similar problems. I explained the issues to my optometrist and he used some extra lenses to work with me to pick out the parts of the lenses that I found difficult or impossible to use. The short answer was that the corrective in the lower and outer portions of the lenses was (were?) not as strong as it should have been, which narrowed the in-focus field, and led to the "tennis match" reading style. With the lenses replaced, I can read across a page without swinging my head. It still doesn't cover dual monitors, but that is due to the glasses not being wide enough. Note: I keep one large monitor directly in front of me and a smaller second off to the side.
