Display pixels duplicated on Mac mini M1

Setup:

Mac mini (2020) Apple M1 - 16g Ram, 500GB Flash Storage

Display:

2008 Apple LED Cinema Display 24-inch (1920 x 1200) - single in use

Issue:

An area of pixels are being duplicated on display. Using the coordinates from the screen capture tool (Cmd + Shift + 4), the source area of duplication is from x352, y1999 ~ x388, y1999 (very bottom, near left side) and are being displayed/duplicated at x959, y0 ~ x996, y0 with pixels x997, y0 & x998, y0 flickering (very top of the display just beneath and to the right of the iSight camera).

Method of Connection:

Two 3rd-party USB-C/Thunderbolt 3 to Mini Display port adapters. One from Answin and another from UPTab (w/ Power Port) specific for Apple M1 Mini, MacBook Pro/Air.

Steps Taken to Diagnose Issue:

The issue is the exact same (same location, effected pixels) with either 3rd-party adapter, and while connected to either of the two USB-C/Thunderbolt 3 ports in the rear of the 2020 Mac mini M1. Both 3rd-party adapters are free of defects and have been tested by connecting the same Apple LED Cinema Display to a 2018 MacBook Pro w/ USB-C/Thunderbolt 3 without issue on display. The display also shows zero issues when connected directly to an older Mac mini (2012) via the Mini Display Port.

Below are some photos taken of the issue discussed. Will I need to send the unit back - it was shipped from China due to the configuration (16gb RAM & 500 GB SSD)? What route is there to resolve the issue?

Note both the top-right above the "discussions.apple.com" url in the browser where the mouse icon is being duplicated & bottom-left where the mouse icon is below the Mail app icon in the dock.
