好像這樣?  如果係呢啲叫color banding.....入門機無乜可以做到，如果用PC做source可以用debanding filter去幫助一下。

https://en.wikipedia.org/wiki/Colour_banding

Colour banding is a problem of inaccurate colour presentation in computer graphics. In 24-bit colour modes, 8 bits per channel is usually considered sufficient to render images in Rec. 709 or sRGB. However, in some cases there is a risk of producing abrupt changes between shades of the same colour. For instance, displaying natural gradients (like sunsets, dawns or clear blue skies) can show minor banding.
Colour banding is more noticeable with fewer bits per pixel (BPP) at 16–256 colours (4–8 BPP), where not every shade can be shown because there are insufficient bits to represent them.
Possible solutions include the introduction of dithering and increasing the number of bits per colour channel.

當時買錯咗JK 第3代灰幕，三月時連費大約兩千幾港幣，
但唔建議買，因為隻幕大過100吋，如果用單邊摩打的話另一面會無咁平衡。
隻幕家下幾巢下，加上第3代幕面無咁滑，如果好光打埋去會有幕紋。
要買就買第四代加雙摩打好啲。

如果打算用得耐啲嘅就唔好慳，買Stewart，最少都買OS。

大mo

想請問樓主，HT1075如利用側投放映3D時，會唔會影響3D效果呢?
