4k Recording Doesn't Work in Camtasia 2019

I recently purchased a 4k monitor (LG 27UL850-W), and I'm having difficulty getting Camtasia 2019 to display what was recorded on my screen. I noticed that if I have my display settings set to "Default for display", the recording works fine...but everything is really large. If I adjust it to any of the Scaled settings (like the center one shown below), the recording is blank:

If I don't use my monitor and record from my Retina Macbook Pro directly, the recording is fine. The resolution is still really high, so I don't believe it is a resolution thing.

When I look at the recording region for 4k UHD in Camtasia, it is a subset of my screen when I have my display set to be scaled. That is bizarre for the resolution of the screen never changes when scaling.

Does anybody know what is going on here?

Thanks,
Kirupa

I guess I'll ask the obvious...is the display itself set at 4k resolution and can your laptop support an extended 4k display? I'm assuming Macs are like PCs in that you'd set the display resolution somewhere in your settings.

Yes and yes. If I tell Camtasia to record at 4k UHD, it only captures a portion of my screen if I am on a scaled size. The only way to force it to record the entire screen is if I make everything larger by setting my display to Default for display. You can see why that is strange, for the More Space setting is just 4k based on the resolution provided:


These various settings are like the DPI values in Windows. The resolution never changes, and it certainly can't go over 4k.

Also, I accidentally posted this under Camtasia for Windows. It should be under the Mac version.

I would call LG support. https://www.lg.com/us/support/telephone

 I wouldn't be surprised if they've received calls for this issue.
They might be a firmware update available?

Joe, when I use Quicktime or the built-in video/screen recorder to record my screen, everything works properly. The final dimensions of the video is the 3840x2160 that I would expect. Only Camtasia is having difficulty here. I would assume this is a Camtasia problem and less of a problem with the monitor, right?

If your referring to silence from me? Let their be noise.

I don't own a Mac, if QuickTime and a built in recorder can record without issue.
I consider that to be self-evident the issue is Camtasia.
