Again, specs do not matter. PiPlay recalculates something every time it is started, and my problem is not that it wrongly comes up with 1920x1080 (since everything is working fine with this option off), but with the fact that it actually does the recalculation itself. The option was not turned off my some "auto setup" function that I clicked. It was turned off manually by the customer, it must NOT be turned back on automatically by PiPlay, whatever the calculations. Give a suggestion, don't change the value.
I don't want to give specs so as not to derail the discussion into rationalizing (or not) the value. It must not be done, period. Apparently that didn't even help that "other forum member" since he or she had to use safe mode anyway.
And I shouldn't have to go back to the settings and change them again at every reboot. How would you feel if the Nvidia drivers, or some game, decided to force all your settings into low at every launch because some dev thought he'd be clever? Nobody does that, wrong or right calculations, unless you click a button to allow it.
