## Duet Display Description
橫掃美、日、英、德及其他 17 個國家最高銷量 iPad App 榜冠軍！

《Duet》能將 iPad 及 iPhone 變成 Mac 或 PC 最高端的額外螢幕。它由一群前蘋果工程師開發，提供無與倫比的效能及畫面顯示質量，並帶給用家零延遲的體驗。

— 提高工作效率 —
在雙螢幕上多工作業能使生產率加倍。對於出差的人而言，這更能提供一個便攜式的方式工作。

— 易懂易用 —
用家只要利用充電線將 iPad 連接電腦即可開始使用。免費的《Duet》電腦 App 會自動偵測裝置，並將其變成高效能的觸控式螢幕。

你無需擔心 Wi-Fi 不可靠、執行出現延遲、畫面出現顆粒以及網路密碼管理等問題。

— 觸控式螢幕 —
透過觸控及手勢操控 Mac 或 PC，享受前所未有的互動體驗，包括雙指滾動、平移與縮放。

— Apple Pencil 適用 —
有了《Duet Pro》，你可以將 iPad 及 Apple Pencil 變成一台專業的圖形平板電腦。我們重新設計了算圖演算法，為設計師、插畫師及藝術家提供反應靈敏的繪畫工具。

此外，《Duet Pro》還解鎖了壓力及傾斜角度感應、停留、防手掌誤觸等功能，讓專業人士能在各大專業繪圖程式中隨心所欲地繪畫，包括 Photoshop、Corel Painter、Lightroom、ToonBoom、Illustrator、Manga Studio 等。

— 媒體報導 —

## Duet Display Reviews in Hong Kong SAR China

### *---- "Be Twice As Unproductive! Extreme Dissatisfaction - Unresolved Apple Login Issue &amp; Lack of Support"
I am writing to express my profound disappointment and escalating anger regarding the ongoing issue with my account and the complete lack of effective support I have received over the past two months.

1.  Unannounced Feature Removal: On June 29, 2025, I lodged a support ticket after Apple Login was removed without notice preventing me from accessing the service I paid for. It is unacceptable that this critical issue remains unresolved two months later, with no proactive updates or solutions provided.

2.  Failure to Support a Paying Customer: As an annual subscriber, I expect reliable service and responsive support. My account has effectively been unusable for two months due to this issue. Furthermore, when I specifically requested clarification or resolution regarding the period of forced hiatus (since I couldn&#039;t access the service I paid for), Customer Support has been completely unresponsive. This disregard for a paying customer&#039;s legitimate concerns is inexcusable.

3.  Chaotic and Ineffective Support Experience: The support process itself has been utterly disappointing. Four different Customer Support Officers (CSOs) have been assigned to my case, yet none appear to have communicated internally or taken ownership. Each interaction feels like starting from scratch, demonstrating a severe lack of coordination and basic case management within your support team. This is not support; it&#039;s a frustrating runaround.

Two months of complete inaction, broken promises of follow-up, and an opaque, disjointed support process are completely unacceptable. I have been patient, but my patience is exhausted. I paid for a service I have been unable to use, and my repeated attempts to get help have been met with silence and incompetence.
-- 4-leaf clover, 2025-08-30

### ****- "Good support"
Encountered some technical issues and contacted Duet Support. The team is responsive and resolved in a timely manner
-- Ed the Duet user, 2024-12-02

### ***** "最好的便携屏幕软件"
即使是windows电脑端安装好对应duet软件，基本上iPad pro 即可自动识别，自动启动。非常方便。且软件可靠性很高。分屏使用和外接屏幕无区别，是出差办公必备佳品。
-- 一天到晚睡觉到晚猫, 2024-11-25

### *---- "Not reliable"
Very unsatisfied.sometimes I spend hours to connect the iPad. But it’s not working
-- intruisive, 2024-09-09

### *---- "Paid for the app a year ago………"
I paid for this app for 118 HKD one and a half year ago for its unlimited use of basic function, and now you turn it into a free app and limited my use in 10 minutes!!!!
-- Theodoric.C, 2023-11-12

### ****- "Not anymore"
Now It doesn’t launch unless you try couple dozens of time open and close the app and rotating it like a maniac
-- xXiHiXx, 2023-11-05

### *---- "售后体验差得不堪"
一免费就变垃圾。
-- 🎗️香港人, 2023-01-18

### *---- "Kept crashing"
Paid for the duet pro but it kept crashing on my iPad. Can’t even open the app and adjust the settings. 

Back then when I was able to open the app, despite stable Wi-Fi connection, duet air still worked poorly between my iPad and MacBook. Not worth the price at all.
-- 9183630274, 2022-10-12

### *---- "does not work on my PC"
it saids windows 8.1 x64 works in the description but after I have paid and downloaded it, they said it doesn’t work on this window version.

wasted my money.
-- jchrvam, 2022-08-03

### ***-- "链接时候没问题，断开了pc黑屏死机了，只能重启"
不知道什么原因，faq中也没有
-- 带错了馒头, 2022-04-16

### ***** "Great app and service"
I have been using the app to set up my iPad Pro as a second screen for my PC when working with documents and spreadsheets.  The app is working fine with very good user experience.  
I found the screen of my PC showed flickering when using the mouse after connecting to the iPad Pro yesterday.  This affected my work badly.  I then wrote an email to the service support of the app.  An answer from Duet Display reached me shortly following my email to ask for additional information for in-depth investigation.  Another email from the service team within the same day provided a solution.  I installed the new version of PC software and the app worked fine again.  I appreciate very much their fast response and assistance.  I would recommend the app to you if you plan to set up a second screen for your PC using an iPad.
-- HoneyPaLi, 2022-04-06

### ***** "To give my old iPad new life"
Is super cold I can use my old iPad mini with IOS 9.3.6(13G37) with Mac OS 12.3 (MacBook pro 13) work good. Supper cold apps.
-- BoscoLam, 2022-03-21

### ***** "Hello"
Good
-- nanawon, 2022-02-10

### *---- "Connection stop working"
I used the same cable and the same laptop as before and now DUET stop connecting my PC to my IPad.
I guess DUET wants me to buy the AirDUET pack!
-- NomysNibor, 2022-01-10

### ***-- "无法连接"
就算用了苹果的线也没法连接。电脑duet不断重复显示已通过连接可是iPad端无法显示内容
-- 苦厄977, 2021-12-27

### *---- "Overcharged me at USD 29.9"
The app said it’s charging at USD 19.9 but it actually charged me USD 29.9. Would somebody please contact me and arrange a refund of the difference?
-- celestetylo, 2021-09-28

### *---- "Connection with iPad drops after a while"
Not sure where the issue is but the connection between my Windows 10 and iPad couldn’t hold for long. It drops after some minutes and couldn’t be reconnected. Tried restarting App and PC application, unplug and plug the cable, etc.
-- LondonStreetMap, 2021-09-27

### *---- "Too slow to be good"
Don’t recommend. Have an old but good 2015 MacBook Pro that doesn’t support sidecars. Thought this could be the solution. It is not
-- wadsf6543, 2021-09-08

### *---- "Bad experience"
I feel that just making money is not as good as the free Project Blue and apply for a refund right away
-- GTOHIT, 2021-06-19

### **--- "Latency issue"
The delay is quite unacceptable, Some remote control software even have smoother experience than this app
-- Eddulered, 2021-05-15
