黎緊 d 新電視主打的賣點好多都係話 support HDMI 2.1, 但關於 HDMI 2.1 我有 d 野想請教下:

1. 而家睇電視節目或電影用 1080 60p 我覺得影像都好順暢,即係 60p 我都好滿意,將來 HDMI 2.1 話可 support 到 4k 120p, 其實以一般電視節目或電影來講 60p 與 120p 分別大唔大? 如果好似我咁本身對 60p 流暢度己 ok 滿意, 120p 是否意義不大?

2. 假若有部新電視話有 HDMI 2.1 接口,但佢個 panel 其實只去到 4k 60p, 咁的話是否根本用唔著 HDMI 2.1 能力?因為 HDMI 2.0 都去到 4k 60p,個 HDMI 2.1 等於發揮唔到功力?

3. 而家大氣電波的節目(例如 TVB)至多都仲係 1080 resolution,成日都話個電視 panel 同節目的 resolution 要一樣(即係點對點)先做到影像最清, 用 4k 電視睇 TVB 己經有 D 矇,主要靠部電視的 upscaler 搭救下至得,第日如果買左部 HDMI 2.1 的 8K 電視,即係用 8K 的 panel 睇 TVB 會唔會比用 4K 電視睇更加矇??要再高幾級的 upscaler 幫手搭救下先攪得返清 TVB 的影像,對嗎??
