唔sure 得唔得
你試試去呢個綱址

http://www.sony.com.hk/support/product/submitLanding.do?lang=zh

㨂下載個Tab, 揀返自己電視型號，跟住會跳去你電視型號個support page , 再click"軟件及驅動程式"下面嗰個三角形button, 跟住會跳咗去Sony Asia 個電視型號support site, 再噤download 個tab, 你會見到一條link寫住"System software update for Hong Kong ",再去到一個site, 拉到最低有個zip file 可以download ...

起碼咁會攞到個physical file ...不過可唔可以咁update你最好問清楚hotline 先呀，費時有乜意外就唔好啦

小弟仲有一個問題，有人同我拗；話響綱上睇到，其實而家已經出嗰啲Sony4k電視其實唔係真正support HDR，新 ...

咁你要同你朋友解釋下咩係既HDR規格

通常分兩種Dolby Vision同HDR 10

Bravia 應該係用HDR10

EOTF: SMPTE ST 2084
Color Sub-sampling: 4:2:0 (for compressed video sources)
Bit Depth: 10 bit
Color Primaries: ITU-R BT.2020
Metadata: SMPTE ST 2086, MaxFALL, MaxCLL

符合以上spec就叫HDR 10，而且係有CEA規範唔符合標準係唔可以叫HDR對應

上年開賣時已經講明x9400c同X9300c會通過FW Update支援HDR

後尾先加入埋x9000c同x8500c都可以通過 FW update支援HDR

Actually I'd agree with 嗰位人兄, at least for non-flagship 2015 models.

In terms of specification it's HDR, but I question whether it really offers the intended benefits of HDR.

I may be wrong, but anyway, my understanding is: High Dynamic Range requires a contrast/brightness range much larger than current LCD panels.  You need a "super-bright" panel to really enjoy it.  Without a super-bright panel I assume it's just a software trick to compress the high dynamic range back into normal dynamic range, and/or tune some gamma/tone curves to fit a normal dynamic range panel.

"佢出呢個update嚟做乜" - Satisfy customer demand, so users will be happy, and old stock can be sold easier.  Everybody will be happy.

都同意你講法，有機會係咁架
如果唔係仲有人買新model?

不過都好高興佢照顧埋我地呢班剛剛買冇耐嘅客

頭先用HDR mode睇4K clips... 開始感受到啲威力

Daredevil 2係Dolby Vision, 所以得LG支援:

真正達標要HDR去到1000nits, 所以要今年既model先得:
http://www.flatpanelshd.com/news ... l&id=1452004019

• High Dynamic Range
• SMPTE ST2084 EOTF
• A combination of peak brightness and black level either:
• More than 1000 nits peak brightness and less than 0.05 nits black level
  

Sony本身話得9300/9400 support HDR, 點解低階出HDR update係因為俾你嘗鮮:
http://www.flatpanelshd.com/news ... l&id=1441207994

Sony launched its 2015 line-up earlier this year and only the X93C and X94C included support for HDR. However, a software update will bring it to all of the Ultra HD TVs launched this year. Existing owners of the TVs will be able to get a taste of HDR even though the TVs will not be able to reproduce the full dynamic range. This requires full array local dimming on LCD displays.

要發揮最佳效果要有FALD (Full Array Local Dimming), 即9400系列, 冇既好易黑位wash out~

多謝你嘅解釋，而家清楚好多啦

即係等於以前買第一代Bravia .... 叫HD compatable ... 其實就係得1080i .... 當然，而家個case 復雜好多

當然要完美顯示HDR就要用OLED
