The ThinkVision P27q continues Lenovo's energy saving. For security Certified for Microsoft Windows 7/Windows 10 Meets 100. ThinkVision P27q-10 Monitor.
I never saw one of those, it looks like a nice monitor, but it is too bad that it does not work for you. I was checking the support site, and you are right, it only came with Windows 8.1 drivers: I don't know if Lenovo will release driver for this monitor, but do you want to try something? When I usuarlly find a harware that no longer works with a newer Windows I try the following.
Sometimes it works, and sometimes don't. Option 1) Can you check the HardwareID of the monitor on the 'Windows Device manager'? Epson Workforce Wf 3620 Driver Windows 10. And post it here. Maybe the USB Video adapter of it has other brands chipset, so we can look if other driver works for it. It may look something like this (but this is an example of the wifi). Idt Audio Driver Windows 10 32 Bit. Option 2) Check if the Windows 8.1 driver will install on Windows 10, just in case.
If you get a message that the driver is not signed for Windows 10, you can override that with some Windows options. Option 3) I also noticed that does a fair job for free trying to recognize new drivers for your hardware. Maybe you can install it, run it with your USB monitor plugged and see if DriverEasy reports any driver for it (it may be recognized as other brand according to the chipset the monitor uses). Sorry, this are not final solutions, but I hope it can give us some hope.
