Ratings and Reviews
Not quite there yet with Windows 10
I got my PC Laptop mostly connected with 28inch 4K monitor when installed the Duet display software this screen stopped working. So you can have triple display either. I tried connecting my 12.9 Inch IPad Pro to it and it does not upscale the resolution to maximum of iPad Pro which I think is 2k. I had to uninstall the software to return my normal setup with the 28 inch monitor. The dues display ha a slight lag/response . It was also a little blurry / graining I think attributed to not using the maximum resolution of the iPad Pro. The touch works but the pencil won’t work in duet display unless you pay for the higher licence. I hope Duet display fixes these issues. In the meantime I will have to reinstall the duet display each time I want to use my laptop with my iPad Pro particularly when I am travelling as a second display.
Developer Response ,
We're sorry about this, please contact our support and pass on to us a DxDiag file from your computer when Duet Display is installed as it will provide us an error log so we can address it on future versions!
So close to perfect
I love this so close to perfect. Had some minor issues with the server app. Both Mac and Windows it won't let me set the resolution to match the iPhone 4/4s. This seems to be causing some display issues when using them. I'd also really like the windows and Mac editions to have the same user experience and options. The only other thing I can think of is support for more than one device at a time and to be able to use it over wifi. I know you went sub to avoid the issues of competitors but it would be nice as an option.
Causes crashes on PC, non-refundable
Having the app installed is causing crashes to occur whenever I try to run games developed by Paradox (seems to have something to do with using Intel integrated graphics). When I tried to get a refund on the app one day later, I was told the app is “ineligible for refunds”.
This experience has undermined my confidence in casually buying apps in future.
I can’t give this app anything more than one star if having it installed in any capacity (not just when it’s running, and not just when it runs on startup - the only way I stopped the crashes was by removing the app completely) on my PC is causing crashes.
