This has been asked but the answers don't fit my situation. My old Dell computer was getting wonky so my daughter gave me her Dell XPS 13-9360. She hadn't used it for a long time, so I updated Windows 10 (64 bit) --it took forever but it tells me now it is completely up to date. I also updated the computer's bios and all the drivers Dell said it needed.


I put it in the exact same place that the old laptop was. That old laptop allowed a second monitor--a View Sonic--and was working fine minutes before I did the switch.


Because the XPS is stupidly thin, I had to used a dock to connect the two monitors. I am using a Cal Digit TS3 plus, also from my daughter. She had been able to use it with this laptop to connect a second monitor and it worked fine. Because the TS3 takes a DisplayPort, I had to get a brand new adapter since the View Sonic uses HDMI. All connected.


But Windows will not recognize any other monitor. It tells me the driver for the laptop is a generic PnP driver. I can't find any kind of Dell specific driver for a monitor on the Dell website. When I looked at the Cal Digit site, the only drivers were for Macs.


I've wiggled all the cables. Everything is firm. As I said earlier, the View Sonic to Computer cable worked fine just before I changed computers.


So is my problem a too-old separate monitor? I have fiddled with the resolution but that doesn't help Do I need a different dock? I went into Device Manager and "updated" every driver I could think of that might connect with a monitor. They all told me the best driver was in place. If the graphics card is the problem, I'm pretty sure I must have updated it when I updated a slew of Dell drivers, though I can't remember specifically. The Display Adapter is Intel UHD Graphics 620


I've run out of ideas. Any thoughts?
