Ratings and Reviews
Good enough for me
When traveling I like to have my iPad with me as a backup in case my laptop crashes. I am also much more productive when working with two monitors than one. So being able to use my iPad as a secondary monitor is great! The screen resolution on my iPad is excellent when using it as a secondary monitor. Duet Display is a reliable option but with some caveats when connecting to a Windows 10 computer.
It is not quick to respond as a quality second monitor. Refresh rate/mouse lag ranges from slight to moderate. Mostly it is slight, but tends to get worse over the course of the day. It performs better after a reboot of my iPad and notebook. Once or twice a day Duet suddenly stops working, but the fix is simple. I open Duet on my notebook and hit “Quit app”. I then open Duet again and this fixes it every time.
If I could count on my notebook 100% then carrying a portable monitor would be a better solution. But, having my iPad as a backup gives me peace of mind that I will not be without a working computer if my notebook should fail for any reason. Duet Display is a serviceable option if you need a secondary monitor and prefer that secondary monitor to be an iPad capable of serving as your backup computer.
The app is good and the support team is divine
First time i write a review on App Store because i was amazed by the Duet support team.
The app worked very well with my iPad 4, which is so obsolete right now it can’t run any other app smoothly. The iPhone screen is quite small to be used as 2nd monitor so i passed on that.
So everything is fine as i expected, up until about recently i get stuck at “Launching Duet ...” screen. As a normal human being, i tried FAQs, Google to find answers but there is no working solution. So as a last resort i turned to support, got an automatic reply email and went to bed. The day after that, i found out that they replied literally 5 minutes after that with a few questions and a solution. That didn’t work right away but that just make me wished i asked them sooner. They kept providing me solutions after solutions, we exchanged emails for a week trying everything, they rotate 3 people in to help on my issue. The team is very polite, specifically pointed out every step along the way, never loose patient and always reply within the hour. After all it was a dumb mistake on my part, so everything is working normal again.
I have to say i worked with many support teams about many issues including Apple, Facebook, Google, Microsoft, Steam, and dozens of app and game developers. This is hands down the best experienced i had working with any team. The app maybe not the best but the team is perfect, and they keep improving with each update.
Awesome App and Unparalleled Support Team
I got this app hoping to use my iPad Pro as a second monitor for my PC computer. After installation it worked like a jiffy, and not only was it a second screen I could use the touch screen of the iPad to navigate in web browsers, pc file explorer, etc.
I then encountered my first issue: when using the software Ableton Live 10 the touch feature stopped working. I reached out to the support team and asked them if they could help me resolve this issue because I knew from the introductory video on their website that the touch features of Ableton live should be working. They responded back in the matter of minutes (on a Sunday!). We went back and forth for a while and it became evident that I had somewhat of a unique problem so they decided to forward my info to the dev team for testing. About 2 days later they came back with a solution that worked (I was running Ableton live as an administrator - this function needed to be turned off).
Duet Display is a fantastic app that allows me to use my iPad Pro like a pc, while also being able to switch to iPad apps fluently. I can use the Live 10 software in a whole new way. This team is here to stay. I am very impressed by my whole experience with this app/team. Definitely worth the $10 download price. Shout out to Sergio from Support!!
