Hello, I had used driver booster by IObit to update anything out of date and when it had finished and after I had restarted the computer, the external monitor's screen was black. I had attempted to troubleshoot on my own and had reset the PC but still the black screen, I also uninstalled and reinstalled the Intel Graphics drivers but still the black screen. I also tried to SFC /SCANNOW but it didn't find any corrupted files. The laptop screen is okay but the monitor still won't work. I tried switching out different HDMI cords but the same thing happens.
