I got my laptop monitor back and working, but now my TV monitor was down. I reinstalled the graphics driver through the device manager and rebooted. In my Intel Graphics Control Panel, only the TV display was recognized whereas the generic Latitude monitor was also detected previously, but no longer. Detect display did not work, nor did extend or clone displays. I'm tied to it because my laptop monitor is off. This renders the laptop useless for work away from my TV. However, on startup, the Dell logo would appear and then after that, the blue Windows icon, but after the Windows icon would stop as bootup continued, the laptop display would shut down and the external TV would kick in. After the Win update, the generic monitor display on the Latitude would no longer work. I have an additional TV monitor setup off of my Latitude on a DisplayPort-out.
On the 20th of March a Windows update was completed. OPERATING SYSTEM Microsoft Windows 10 Pro (64-bit)
