Better indication of how screen dimensions are calculated based on retina/non-retina displays

It turns out Camtasia v3.0.6 makes it very confusing how screen dimensions are calculated depending on whether a retina/non-retina displays are used.  This is from your support team:

"Currently when Camtasia is selecting the pixel size on the screen, it will look at what the exact number of pixels are (if you have a retina display device, this means that selecting a size that seems like 1280x720 is going to be double that size (2560x1440). Looking at the options you are seeing in the list there, you are choosing 2880x1800 vs 1280z720 HiDPI (this I would assume will utilize the retina settings, doubling the amount of pixels on your screen). Do you have an option to try 1280x720 non-HiDPI (otherwise, I may recommend using 1920x1080, which is another standard HD resolution)."

See for more context.

Hello Roger;

There is not an option within Camtasia that will ignore the Retina / Hi-DPI functionality within a Mac  (nor in other Mac apps that I am aware of, though the community may know of some). I personally use an open source tool called RDM (Retina Display Manager) which will go about and ignore the mandatory Apple scaling and provide a true resolution, which helps with defining items at specific sizes.

Perhaps others within the TechSmith community have input on applications that might bypass the forced scaling on Apple devices?

The problem is when trying to pick a Custom size in Camtasia, Camtasia makes the calculation based on retina/Hi-DPI functionality.  Most other recording software calculated based on absolute pixel dimensions.  I ended up using SwitchResX to switch from a 16:10 aspect ratio to a 16:9-based aspect ratio and non-HDPI to avoid the weird custom size calculations.

There needs to be an official, TESTED solution from Camtasia on this.  I was promised that version 3 would correct the problems with a Retina display but it did not.

When I select the correct dimensions for my instructional videos at 1920x1080, it only records a quarter of my MacBook Pro screen (minus a band at the bottom that's extra).  If I record them at double size, then the resulting videos look AWFUL and are blurry.

I don't understand why they can't simply put a RETINA screen size on the list of options, and get a solid solution for this.
