Sergey was able to offer me a solution that worked like a charm, I now am seeing 1080x1920 (1080p vertical display) and the quality looks great! Sergey was also very kind and asked the I send the $200 bounty to FreeSWITCH, so I will do that today. I have included his reply below in case anyone else runs into this problem because I found nothing after days of searching on Google.

To specify video size need to use background png file with the required resolution.

If you want FullHD then need use png with 1980x1080 size.
How to use this image

<action application="set" data="core_video_blank_image=/tmp/hello.png"/>

or from FS console

originate {core_video_blank_image=/tmp/hello.png}user/1018 &park()
