так почему же мы можем обр. к свойствам как у массива и тд...?

1920x1080 на 25 дюймах или 2560x1440 на 27 дюймах
В некоторых моделях встречал функцию поворота в портретный режим, так ли это удобно
Есть ли разница между 60гц и 75гц в отношении влияния на усталость глаз?
Потянет ли такая конфигурация разрешение 2560x1440? (не в играх)
