Cloudalize desktop resolution is not automatically converted to the iPad resolution.
If your iPad has a retina display, the desktop is going into a lower resolution. For example 1600x1200 with a 85% zoom. Which actually results in a resolution of 1366x1024.
At this point we can't offer a solution for this. It's related to the technology we use to stream the desktop to your device.
As a workaround you can use the web receiver instead of the iPad app. When you use the web receiver, you can go to the options and change the display resolution setting to use device pixel ratio. As this is through a web interface, you'll have to pinch to zoom.
We can't commit to a good solution yet. Please follow this article to be updated about any fix in the future.
