而家又唔係 2008 年.

有光纖 HDMI 15M 行 8K 都綽綽有餘呀.

又推垃圾

15M太長，有失真

I see. But you are not telling me a 15M HDMI cable will outperform a 10M one if its same model, same brand and same spec ??

simcity,
又出雪花又黑畫面 is not my case.I use with my 15M cable have a perfect colour screen. It's better than my 10M cable used before. That means in 15M also can find a perfect cable.

wongchris,
你都好出力賣你條線。不過你條線最長都張祗是得12.5米,我看不到有15米的板本,會不會又是質量問題不能做15米。如果做出來又是花畫面呢。不過呢條線無論如何都是太貴了。

Longer than 12.5m is not stable in 1080p and that why no CAT 2 cable in so long distance.

The 15M used was "TTL" brand. Actually, it performed much better than in your case (i.e 又出雪花又有時黑畫面). But only when I change to 10M cable did I realize the improvement was huge.

我現在用了一條15米HDMI線,好過之前用過的那些有ATC測試證書的短線才。他們在3米到5米時可行10.2G架,非常勁,但一到15米就……
他們大多數四千元以上的都能通過10米到12米的。但一到15米時侯就差很遠了,又出雪花又有時黑畫面。總之就有問題。所以真正能在15米或以上能有真正通過ATC測試的線就非常少了,如師兄們發現有少過六千元又有15-20米ATC政證書。通知聲,謝謝

If possible, I suggest using 10M cable. It's huge improvement. I used to have 15M TTL HDMI for my sony VW60 and change to 10M later on. Around 30% improvement.

首先，官方所指無論"Standard"定"High-Speed"線材，都必須通過嚴格的 HDMI ATC 測試 (如沒通過有測試者另作別論)，以往ATC測試可能有1.1, 1.2, 1.2a...等等。

只有通過 HDMI ATC 測試線材方可用上 HDMI Logo - 『市面不少所謂貴線...都沒有用上 HDMI 真正 Logo』

不過當 HDMI 官方推出 v1.3 時，已經明確表示測試線材只有兩種:

Category 1 【Standard】 - 支援4.95Gbps
Category 2 【High-Speed】 - 支援v1.3最高速度10.2Gbps (已經是 HDMI 最高傳送 bandwidth 340Mhz)

"它強調並沒有中間的線材"(當然沒有通過測試者不在討論範圍)

線材傳輸的最高帶寬(10.2Gbps - Bandwidth 340Mhz)，可以成戊B理 1080p 信號外，更包括增加的色深和/或增加的刷新率。高速電纜也可以滿足更高解析度顯示器的需要，例如 WQXGA 電影顯示器（解析度2 2560 x 1600）。

1080p只是其中一項，v1.3弁鉬楨韞u考慮 1080p。

由此可見，市場上只有少數線材能通過 Category 2 (High-Speed 測試)，原因是 Category 2 測試對線材的要求很高。

不過，今年10月起，組織規定所有 HDMI 產品包裝都要列明產品是通過什麼速度的測試 (如沒有通過測試者另作別論)。


HDMI 1.3b
Released March 26, 2007.

HDMI compliance testing revisions. Has no effect on HDMI features or functions since the testing is for products based on the HDMI 1.3a specification.

HDMI 1.3b1
Released November 9, 2007.

HDMI compliance testing revisions which added testing requirements for HDMI Type C mini-connector. Has no effect on HDMI features or functions since the testing is for products based on the HDMI 1.3a specification.

當然，如果擁有 High-Speed 加 SimplayHD 測試就更加理想，因為 SimplayHD 經過二百多個測試程序，以確保其兼容性。

是否正式通過ATC測試嗎...就要問清楚了。

stephenwan 兄弟,

你唔洗煩, 你試下 PM 比呢位人兄

我之前, 也幫他買過 HDMI cable, 他是可以提供上門測試, ok 之後先比錢. X 2

His HDMI cables are very good but the price is very very resonable. Nice and very helpful seller. highly recomend !!!! No need to buy high price cable.

所以更加需要選擇已通過 HDMI ATC 或 SimplayHD測試，以確保質素。

所以問問有冇人己試過用15m hdmi support deep color 而沒有問題
_____________________________________________

currently there is no software that is encoded in deep color even your blu ray player and projector support it. it is just a marketing gimmick right now.

短距離要 passed High-Speed 高速 HDMI ATC cable 啦!

而係長距離(＞10m)，更加一定要有測試、同有質素先好...
要PASSED HDMI ATC 就一定冇問題。

I'm using the monster m2000 hdmi cable, and my fan have one M2000 35ft cable that can support 12bit color. So you may able to made a special order from the net, which's support 12bit colour upto 50ft. But it's only available in US, and limited production.

Try this link & ask, and they ship international order.
