The Samsung Q80 has a great native contrast ratio. It is, however, lower than most TVs with VA panels. This is because of the TV's 'Ultra Viewing Angle' layer that improves the viewing angles at the expense of contrast ratio. This is very similar to the Samsung Q90R and the Q900R. The native contrast ratio of this TV measures slightly better than other TVs we've tested that support similar viewing angle boosting technology.
Unfortunately, just like the Q70R and the Q90R, the TV's local dimming can't be completely disabled in the normal settings menu. In order to measure the native contrast ratio, we had to disable PC Mode Dimming in the TV's service menu, and then activate PC Mode and Game Mode at the same time.

When there are subtitles on the screen, there might be noticeable brightness changes in the scene. This is normal for Samsung TVs with local dimming features.
You can't disable the local dimming feature through the regular menus on the TV. Local Dimming was set to 'High' for these tests.

The Samsung Q70T has an outstanding contrast ratio, capable of producing deep and inky blacks. Unfortunately, it doesn't have a local dimming feature to further improve it.

Interessant at se, at Q70T (kantbelyst) native contrast > Q80R (FALD) contrast with local dimming.
Ja, jeg ved godt den seneste snak gik på Q85R og ikke Q80R. Forskellen skulle vist være antal zoner, men ellers er de to modeller vel tæt på hinanden.
Det være sagt, så er jeg enig i, at Q85R er et bedre køb end Q70T lige nu, men Q70T bør absolut ikke afvises alene fordi det er kantbelyst og uden local dimming - særligt ikke når det engang til næste år kommer ned i foræringspriser som vi så ofte har set det med tidligere års modeller. Kan man leve uden de lidt bredere betragtningsvinkler er det absolut et udmærket TV hvad farver, lysstyrke og kontrast angår.
