I have a thinkpad T420 and have two Dell monitors hooked up to it via a thinkpad USB 3.0 docking station. Up until two days ago both Dell monitors were working fine. I booted up my laptop the other day and now only one is being detected. I've tried uninstalling and reinstalling the driver for the second one, unplugging everything from everything and rebooting, but nothing seems to be working. I'm stumped. Any ideas are appreciated. Thank you!
