X1 Extreme Gen2: External monitor choppy "only" when laptop lid is closed

2019-10-31, 17:22 PM

Hi,

 

I just received my X1 Extreme Gen 2, configured with top specs.

My configuration is for home-office, so the first thing I do is connect an external monitor and wireless keyboard+mouse. I also work most of the time on the large monitor, with the laptop lid closed. 

What I did:

. Run all updates available for Windows 10 Pro and via Lenovo Vantage (so everyhting is up to date).

. Connect Dell monitor via HDMI. Works perfectly when laptop lid is open.

. Configured laptop so when lid is closed, it does nothing.

. Lapop power management is configured for "performance".

 

What happens:

As soon as I close the laptop lid, whatever graphics I have running on the external monitor (youtube video, browsers, etc...), even the mouse movement, becomes very choppy or lagging.

When I reopen the laptop lid, the issue goes away.

 

Any idea how to solve this problem?

Thanks!

SOLUTION: it turns out that the "external PnP monitor" driver needs to be updated separately.

 

While laptop lid is open and external monitor is connected, go to display settings, select the external display, and find your way to update the driver. In the end, Windows will automatically find your specific monitor's driver, and replace the "generic" one.

 

After this update, the external monitor worked perfectly with laptop lid closed.

 

Hope it helps.
