Duet Display Reviews


Does not work.  Madadrol  1 star

Program will not work with windows 10. Multiple install attempts failed.

EJ from PR

Great and affordable  EJ from PR  5 star

I work a lot with data and having a portable second screen is a blessing. Duet works great, is affordable and all you need is your iPad and a USB cable.

Hope Cookie

It’s a Paid Demo  Hope Cookie  1 star

For $20 or so, you get a fuzzy second monitor and it asks you to upgrade to the PRO version for another $20/yr. So just be aware of what you are geting for this purchase. The second monitor does not look sharp until you pay a lot more money.


Just What I was Looking for But!!!  CaricatureArtGuy  3 star

Works great so far with my Asus gaming laptop and 2018 IPad Pro 12.9 for drawing and other Windows 10 desktop programs but if you use Kodi on your pc it will cause it to crash every time,this is a widely known problem (unable to create GUI)you need to uninstall one or the other.


Ruined by poor pc support  ImOnALampshade  1 star

PC version blue screens my MacBook (current model as of this review) when running windows when I connect my iPad. Had to uninstall the client because it messed up my graphics drivers. Haven’t tested it on MacOS, but I got this with the intention of using it for my pc. Wish I could get my money back.

Al h

Terrible experience with install  Al h  2 star

Crashed my MacBook Air had to waste a couple of hours to restore. Contacted support they sent me some programmer materials to type into the terminal to get it fixed. I am on now with both Duet and my Mac is working. Little scare and time wasted during the installation. Hope this will work moving forward. I like the concept and hope they will out the issue with install.


Does not extend -only mirrors and badly  antzsszzzsss  1 star

Waste of $10; at least it was 50% off. Installs ok. Cursor only works on iPad OR on laptop not both. Does not extend display regardless of whether or not mirror option is checked. IPad 2 with MacBook Pro 2009.


Fantastic!  JzZ6358514743654  5 star

I'm a programmer, and duet is a portable and effective way to have a second screen to view different snippets of code. It's cheaper than a second monitor, and I can carry it with me wherever I go!

Defebwar the Insane

Windows 10 January 2019 (Not Working)  Defebwar the Insane  1 star

This flat out does not connect & will not connect. The online support system is virtually non existent. It should honestly be a free app til you find out if it will actually work for you, the fact that so many people have had the same issue, and this hasn’t been pulled from the App Store, screams fraud to me. Don’t market this as working with Windows 10 if it doesn’t. Esp if it doesn’t work from the get go, following only in app and online instructions from Duet themselves. All help articles related to it not connecting give you the same instructions, which the app also gives you and then it tells you to email the company if you have problems. Why don’t you just write a support article that lists the steps your company is going to tell customers anyway? Submitting for a refund (finally got my receipt from Apple).


Nothing worked! Including Apple Support .  Stoneyrjg  1 star

Couldn’t get it to work! Couldn’t contact Developer Support! Couldn’t get thru to Apple Support Said the order number from their billing email was invalid 3 times. Gave up. No More Apps from this store.


Do not buy if you have a PC  Thephotoshop  1 star

I’m sure this works fine on Mac but this a has caused me no end of trouble on the PC over the time I have used this app and across the various updates the desktop software has at versions times broken VR, graphics acceleration in all programs, my entire suite of adobe programs, an array of games depending on the display technology used and even google chrome. Clearly development of this for windows and they should really just drop support if they can’t make it work. It’s a shame since the tools they have are very good but that can’t save a failed implementation of the core technology.


Please add to Mac App Store  Lopafdig  1 star

I can’t download apps from the internet on my Mac, due to it being a department of education computer. I can get apps from the App Store though so please add it in there.


Smal screen  alainbars  1 star

I cant see anything the iPad changed to small screen. Don´t buy it


Damaged the bios of my win 10 laptop during install  PaulBlanch  1 star

Had to send it back to dell on the second day of owning it when during install on dell 13 inch win 10 it froze up during install Thanks for the repair bill. The app is 50% off for a reason by my experience. Don’t take the chance. Get you self a portable USB powered monitor.


Extremely useful if you have an iPad already  spwhite  4 star

Duet does exactly what it says, and adds touchscreen functionality to your Mac. A MacBook and iPad becomes the most portable and functional dual screen setup, and a 3rd monitor can also be added via HDMI. All works almost flawlessly, and they are responsive to problem reports.


Scam - beware if using office 365  L-Jay:)  1 star

After installing on PC, all office 365 apps no longer opened. After no joy with their support, I read the reviews ( I should have read on purchasing) to find this is a known issue with no warnings from the developer. Even more disturbing is that they ask you to contact App Store for a refund knowing full well the onus is on the developer. A very dodgy experience- do not make my mistake!!


does not work win10 surface pro 5  Navtower  1 star

hopefully will be getting a full refund


Useless!!!!!  wcewou  1 star

Pc screen just flickers and black screen on iPad. Doesn’t do anything it advertises. Waist of time!!!!!

A guy in love with a game

DUET F*CKED MY STEEZE  A guy in love with a game  2 star

Okay so I installed duet maybe 2-3 months ago on my desktop computer and laptop (windows 7 and 10 respectively) and I thought everything was fine, in fact it was great for writing/composing music on while using musescore in collaboration with it, however, I tried launching Dark Souls 3 on my laptop and Life is strange on my desktop neither of which would launch, they would only launch through the integrated graphics. Turned out that upon installation duet altered some setting, which basically rendered my nVidea graphics card useless when speaking gaming wise. I have now uninstalled duet and everything works perfectly fine but not before forking out $100 on computer support because I didn’t know why my computer was acting the way it was. TL;DR: don’t buy duet as it needs the computer application to run properly which screws with the graphics settings causing apparently any moderate to high intensity game to freeze upon start up.


developer dishonest about serious issues in this app  rob__j  1 star

- duet has been broken since 10.13.4 (6 months ago) - buggy AirPlay implementation is no replacement for the apps previous functionality - website and help section tries to cover up the serious issues - overall lack of transparency from this developer. app should be removed from the app store - now forced into subscription to get original functionality back !!!! i’ve already paid for this bad experience :/ -buy luna display instead, it works!! everything I wanted duet to be


Dock bug  Joshua8598  2 star

This is one of my favorite apps of all time but until the bug that makes your dock disappear after you close the app is fixed I have to bump it down to 2 stars. A hard reset usually fixes the problem but it’s still a huge annoyance. Please fix.


Doesn’t work  Abcdefghijklomn  1 star

I got it because I use illustrator, the set up was confusing, and the zoom does not work, nor does moving around the screen to work on different areas of the artwork. This is one I would love to just plain get refunded. Tech support only via email, slow response, doesn’t answer the questions....rather responds with canned statements that don’t address the question.


Mirroring not extending screen  Puertoricanism  1 star

Previously, it was as simple as plugging play. Now I emailed the app developer a week ago and have yet to receive a response regarding a fix with the bug.


Glitchy screen - great concept  bam19892008  3 star

I have been search for something like this for a long time. Overall a good solution however, when using WiFi feature the screen is too glitchy to use. When using wire connection their is still quite a bit of lag.



I use this on my 10.5in iPad Pro alongside my MacBook Pro. It turns my iPad into a perfect second screen for giving me a mobile workstation that drastically increases productivity. No input lag, super smooth. Love it!

The Cerrone Family

This was too good to be true...  The Cerrone Family  2 star

I recently bought an iPad Pro 2018 and was very excited to use it as part of my day to day workflow. I decided to look apps that allowed me to extend my PC display to my iPad to take advantage of its wonderful screen. I came across this app. It had good ratings and was recommended many places online so I thought I’d give it a shot. I was pleased to see how easy it was to use but it very quickly went downhill from there. The app showed in a lower resolution than I hoped, which is understandable. What is not understandable, however, is why the app freezes every time I touch the screen, which is the main reason I purchased this app. This combined with the fact the the app doesn’t support wireless or have full Apple Pencil support without a monthly subscription is why I’m giving this app a 2 star rating. I seriously disappointed.


Outstanding tech  Tgambee  5 star

I use multiple monitors at home and always miss I on the road, now I don’t need to miss it!


Worked once and never again  ntpyles  2 star

For a $10 app, I expected 0 bugs and a seamless experience. It worked one time for me and never again. The help on their website is nonexistent as well so you’re left with an app that doesn’t work. My Mac has the latest version of their software and it still won’t display to my iPad. Very frustrating.


Wow  _Eucalyptus_  5 star

I’m normally too lazy to write any reviews but this time I really have to say this app is a blessing. I just got the new iPad 2018 last Christmas, I never thought it would work like this. It’s insanely useful and the app was just $10. There’s literally nothing to lose and definitely worth the ten bucks. Hope this helps anyone.


Doesn’t work with Photoshop  TheTortugaPanda  1 star

I wanted this app to use Photoshop directly from my work computer so I could easily switch back and forth. The basic version does not support the Apple Pencil at all, it just treats it like a move tool regardless of what actual tool you have selected. If you want to use it as a drawing tablet, you have to pay monthly for that feature.


Not great  Goran99  2 star

I really hate to leave negative feedback but after paying and spending far too much time setting it up and trying to get it working I am giving up and going with their competitor.


Doesn't work  Martynet  1 star

I bought this app because I used to use iDisplay app before but it doesn't work anymore... So I decided to invest few bucks into Duet and it doesn't work either. Connecting my 12.9" iPad Pro to my 27" iMac to extend the screen and it just doesn't work. What's going on?


Extremely disappointed.  AEsmerio  1 star

It works well if you dont have an graphic card on your laptop. I've GForce m960, and all the games can't be played after install the windows drive to use Duet Display. There's plenty of forums that people complain about the same issue. The way to fix it is uninstall the Duet drive. That's so b frustrating. I've bought Ten 1 grips as Duet site recommended and i can't use them. All my 60 (iPad grip support + Duet Display license) are completely waste of money.


Rubbish  The EBG  1 star

Continually crashed and was slow and clunky when it managed to run. Trash.


Half false advertising  Yinks23  1 star

This app is a half false advertisement yes the said share ur screen but it only work for from pc to iPad or iPhone not for your phone to pc that was a not cool I paid for this app and I did not get wat I paid for pls change your videos and be for specific sometimes pls😡😡😡🤨


Not for illustrator and photoshop.  KrazeD_  3 star

This is a great idea for an app it does work but not exactly what I wanted. I already have two displays so I wasn’t really getting this app for another it was more wishful thinking. A Windows “Astropad” replacement it is my bad I should have done a but more research on the app before buying. I have been testing this app on both Photoshop and Illustrator and its not great. Maybe I’m missing something but it’s very unresponsive. Doesn’t recognize pen pressure in Illustrator. Now for someone that is just looking for a second display this is a good app but personally I vote against buying it for using applications. I can’t not speak for how well this works with Mac applications but for windows very under the bar.

TM Goff

Great app  TM Goff  5 star

Great app. Does what it sets out to do. And does it well. Is the pro version worth it for iPad pencil support? Yes. It's great. I wish it had a wireless option, but I use my Wadom wired. This is better.

Micheal O

Exceptional App  Micheal O  5 star

Possibly my favourite app ever. Must have for anyone that is used to dual screens and wants to be productive on the move. Then add in the fact that your second screen is touch enabled. Just amazing.


Fantastic - I can work on 4 screens now  Migo321  5 star

Mobile office: laptop plus iPad 2 screens, office setup: 4 screens: 2 external monitors, HP spectre + iPad underneath.


Slow  Jeancasedo  2 star

While using the App my iPad gets too slow so I can't work. Please improve it or give me my money back!
