Is there a thing I’m missing with the Lenovo docks and the flickering screens? USB-C dock? Thunderbolt 3 dock? Thunderbolt 4 dock? It matters not. Lenovo Dock Manager says dock firmware is up-to-date. Windows Updates say laptops are up-to-date. Lenovo Commercial Vantage says laptops are up to date. Cables replaced. Flicker. Flicker. Flicker.
