Thanks for sending the diagnostic logs.
Based on your dxdiag info, your Intel graphics adapter on your primary machine is an old version with WDDM 1.1 model.
Desktop duplication of primary monitor to other displays is disabled in Windows display settings of Windows 10 with old version of graphics adapter (< WDDM 2.0). Please try to update your Intel driver version from their official website or maybe go to https://www.intel.com/content/www/us/en/support/detect.html
