I cannot connect my HP Pavillion 15t-eg100 to two external monitors. I am using a lenovo docking station and two lenovo ThinkVision T24i-30 monitors.
I have two monitors, a keyboard, and a mouse plugged into a docking station. When I plug the docking station into my laptop via USB-C, the keyboard and mouse work just fine but the monitors do not. All accessories work when connected to another laptop (which is running Windows 10). I know this is not an issue related to cables because I can swap between laptops and the screens are instantly detected. It is worth noting that the USB docking station is also actively charging my computer, so it should be capable of sending video unless I misunderstand.
Here are the steps I have already taken:
- Rescan to detect monitors several times
- Check all cable connections/power
- Update all my drivers
- Check for software updates and restart my computer
- Install Thunderbolt Control Center to attempt to detect displays
- Install Lenovo Accessories and Display Manager to attempt to detect displays

2025-03-17T08:52:03+00:00 Hi All,
I have been struggling to resolve this problem for long time as well!!
But I am able to fix it by following a method that I saw online. I unplug everything from my laptop and leave it alone. Then long press the power button for 40 seconds, have to be exactly 40 seconds! Then turn on the laptop and connect all cable, HDMI/USBC wire.
It works well now! I am about to connect two monitors at the same time !
Absolute genius! I have struggled with this all weekend with no solution until now. Thank you for taking the time to post this solution.
You win the Internet this month :-)

2025-03-12T14:07:21+00:00 Did not work for me either. Tried several variations of this 40 second magic.Edit: Okay, I found the issue with mine. When connecting/disconnecting the display port cables on the docking station side, the monitors would react with a signal/no signal. This said to me all the other connection to the monitor must be good. However, I found later that the cable connection at the back of the monitors was not all the way in the connector. This was truly an interface issue between the keyboard and the chair!
