A:Answer Samsung TV models in the 8K Q900R series will support 8K video at a HFR of up to 60 fps through HDMI 2.1 connections. Those who bought a Samsung 8K Q900 last year, will be able to get a complimentary upgrade of a board in the set’s One Connect Box (installed professionally) to accommodate 8K HFR over HDMI 2.1, Samsung said.
In 2019, only the 4K Q90 and the 8K Q900R QLED TV series will support High Frame Rate (HFR) 4K Ultra HD video (4K/120 fps). QLED models in the Q60, Q70, Q80, Q90 and Q900 series will support HFR 120 fps at 2K and 2.5K resolution (2K/120 fps, 2.5K/120 fps).
