Default Big Sur 11.4 / now not recognizing display

My mac is no longer recognizing the display after the Big Sur 11.4 upgrade yesterday. The display will flicker with the logo and go to black, I've tried the most recent driver and my mac is not recognizing that an external display is plugged in. Any clues on how to fix and troubleshoot this please?
