непонятки с изображением по HDMI

Flaber · 06.02.2019, 15:45

Доброго времени суток
Имеется ТВ LG 55SK8100, подключен по HDMI к MSI GTX 770. Кабель 3м Philips
Все вроде бы норм, но не могу понять 2 вещи:
1. Почему в режиме 1920x1080p@120 Hz, ycbcr444 цвет передается без искажений, а в том же режиме, но с частотой 60Hz (в панели управления nvidia, последний драйвер) появляются "дефекты" - как будто урезанный цветовой диапазон на каналах.

2. Почему нормально работает режим 4k@60Hz, хотя его ввели в версии 2.0, а моя 770 поддерживает макс. HDMI 1.4a (с оф сайта MSI)
