給你個數據,60公分適合27吋
正解。
說一個經驗，之前27吋螢幕臨時作他用，找了一台鴻海40吋的暫用
距離大概就是60公分上下，27吋視野正好，40吋就需要扭頭轉動，極不適。
200公分剛好頭部不用轉動，75吋螢幕盡收眼底，沉浸感滿滿的。
上面這個連結是我認為比較科學的建議尺寸, 其餘的展場說明都是告訴你買大的
簡單來說, 就是不要看電視看到 "一眼看不完" , 因為會越看越累
1) 一般使用場景: 直視電視中心點, 然後左右邊框跟你眼睛夾角最大不超過30度, 用畢氏定理計算一下就知道電視與眼睛的最小距離是多少. 例如距離2.06公尺的話, 適合尺寸是50"電視
2) 劇院場景: 直視電視中心點, 然後左右邊框跟你眼睛夾角最大不超過40度, 這樣的話1.98m適合尺寸是65"電視
不論哪種場景,75"對您來說都太大了

看畫質的好壞(恕刪)
您誤解這張圖了, 在Rting底下有註解如何解讀這張圖 (這張圖並不是用來決定電視最佳觀賞距離)
例如: 你現在有一台65"電視, 在距離4"-8.5" 你可以很清楚的辨識1080p和4k的畫質差距, 距離超過8.5"的話, 1080p和4k對你來說是沒有差異, 這個時候升級電視成4K畫質就沒有意義了
This chart shows the point at which an upgrade in resolution becomes worth it depending on size and distance to the TV. Each line represents the optimal viewing distance for each resolution, but any TV that falls within the range of that color will be suitable to notice a difference in picture quality. So, for example, if you have a 65 inch TV, the viewing distance at which the eye can actually process the details of 4k content is about 4 feet. However, any distance between 4 and about 8.5 feet will be enough to appreciate the difference between 4k and 1080p on a 65 inch TV. Go too far, and the image will look identical to 1080p HD.
The chart suggests that at a certain point, 4k UHD may not be worth the upgrade—if you're sitting more than 7 feet away and have a 55" TV, for instance. Really, though, this chart is just a guide, and as 4k TVs have become the standard, the question of whether it's worth it or not is a moot point. While your eyes may not be able to tell the difference at a certain point, your next TV will more than likely be a 4k TV anyway. Knowing the optimal viewing distance for the resolution can help you determine a living room setup that takes full advantage of your TV's resolution, but since angular resolution is almost a non-issue with UHD content, we recommend using our calculator tool at the top of the page, which is based on the optimal field of vision.
