I have DELL U3417W monitor with 512MB ATI Mobility Radeon HD 3670 (Dell) graphics card on Dell™ Studio XPS™ 1640 on windows 10 Home edition.
My laptop sometime loose monitor native resolution of 3440 x 1440 and revert back to 1920x1080. I have to disconnect HDMI cable wait for 5 seconds and connect back. This is a problem in long term as it might just cause tear and wear in HDMI port on laptop. Is there any way to simulate physical disconnect and reconnect of HDMI cable through powershell script or some other way?
