"If the flat panel and the wall are basically one, there's no eye-strain."

Not true. You do eliminate one source of eye strain because the eye will no longer struggle to get 2 different planes some distance apart in focus at the same time.

There are still some sources of eyestrain you don't eliminate:

- keeping the eyes at a mid to close distance focus for long periods. The screen isn't far enough way to be regarded as distant or infinity, which is what is required for the focussing muscles to be at their most relaxed.

- screen brightness can be an issue. I don't mean the brightness controlled by the brightness setting but bright as in how much illumination the screen puts out. Probably not the case for some flat screens but it's likely to get worse as screen brightness and contrast ratios improve.
