X1 Yoga (2nd Gen) OLED Auto Screen Dim w/External Monitor

2017-09-28, 14:58 PM

My X1 Yoga 2nd Gen OLED has a great feature wherein, outside of normal Windows screen dimming, within the Lenovo Settings app, user can set a "Task Bar Dimmer" timeout and a "Background Dimmer" timeout. This is described as a power-saving feature, but in reality its a great way to ensure that the OLED screen doesn't experience burn-in over time when on-screen items are displayed for prolonged periods.


However, when I connect to an external monitor (which is almost always), the Task Bar Dimmer and Background Dimmer ONLY affect the external monitor and no longer affect the OLED display, where (IMO) this is far more important.


Am I missing something, or is this a bug? Dimming the taskbar on the OLED is far more critical than on my monitor.

Dear AndyCapp,

ThinkPad development team is trying to duplicate your symptom, however, no success so far.

Can you provide more information for the below items?

 - Windos OS version:
      - preload or install by yourself ?

 - Machine Type Model:

 - BIOS / Embedded Controller version:

 - Intel Gfx driver version:

 - External Monitor Product name / model:

 - How do you connect the external monitor ?  HDMI on X1 Yoga?, Type-C/Thunderbolt3 Dock?
