New install has artifacts, curious how to look up settings on old machine.

I had an old 16.04 LTS linux install that ran great (no visual tearing, dropouts, etc.) for quite a long time. However a partial-update to that install caused kernel panics and boot failure, so I took it as an opportunity to move to an SSD and update the OS to Ubu 18.04 LTS (the rest of system is unchanged). Now I've got ZM back up and running on my new 18.04, but have some visual tearing/artifacting that I'd like to eliminate.

Since the old HDD is perfectly readable, I'd like to go back and look at those old settings if possible. Are the monitor settings in a location on that drive that I could just peruse through and look at? If not, are there prescribed ways to eliminating tearing? Currently using FFMPEG on Amcrest cameras that, as stated above, worked perfectly fine prior to reinstalling 18.04.

Fire up a pc with the old hard drive. Take a dump of the zm database and use it in the new server.
