Dear Intel Support Team,
Like many other owners of Lenovo Yoga 2 Pro (20266 / 80AY) I have been living with this Screen Flicker issue since I bought my computer 3 years ago. The issue also affects other vendor's models like HP, Sony, and Dell and it's now isolated, well documented (with workaround) and I hope it will be fixed in a next driver update for Intel HD Graphics 4400.
It's definitely a very old complaint in the Lenovo Forum with more than 114,330 views.
Please push Intel Engineering Team to fix it ASAP.
1) As described in the guidelines for Graphics questions here is further information about the issue and my specific device:
Only when ON BATTERY @ 3200 X 1800 and REFRESH RATE 60Hz the screen will be fine for awhile, and then it will suddenly start flickering, turning black for a second or two, then the screen coming back on briefly, then back off, on and on for as long as 60 seconds.
WORKAROUND (Patch): Setting Refresh Rate to 48Hz "when on battery" the flicker will never happen.
NOTE: When plugged on charging the screen flicker will never happen on 60Hz or 48Hz.

- My Lenovo Yoga 2 Pro Full Setup Guide
NOTE: Screen flickers often when in use or not (when on battery @ 3200 x 1800 – 60 Hz). It’s not related with any application or screen brightness.
Often (51-99%): X
Very Sporadic (<20%):
