+msgid ""
+"Instead of adjusting the backlight, this app uses `xrandr` to change the "
+"brightness of the image displayed on your screen. This can be useful for "
+"displays without an adjustable backlight, displays with a too-bright "
+"minimum, or too-dark maximum backlight, or OLED displays. Setups with "
+"multipe displays (maximum 4 displays) can also be adjusted with different "
+"brightness levels."
+msgstr ""
+"Zamiast dostosowywać podświetlenie ekranu, apka wykorystuje „xrandr” żeby "
+"zmieniać jasność obrazu wyświetlanego na ekranie. Może to być użyteczne "
+"dla ekranów pozbawionych regulowanego podświetlenia, ekranów ze zbyt jasnym "
+"minimalnym albo zbyt ciemnym maksymalnym podświetleniem, czy OLED-ów. Działa "
+"z wieloma ekranami (maksymalnie czterema), z których każdy może być ustawiony "
+"na inny poziom jasności."
