Yoga 460: Graphics Driver Problem

[kevinpo]

I have just bought Yoga 460 a week ago.

I've had this message saying "display driver stopped responding and has recovered" and the screen started working abnormal. I have been looking for and tried many solutions (from Lenovo Forum, Microsoft Support Site, Youtube) as listed below:

1. uninstall and update the drive from Intel.
2. Uninstall and update the drive from Lenovo Support Site
3. Set TdrDelay to value 8 / 10

However, all methods failed.

Plus, a message " Application has been blocked from accessing Graphics hardware" sometimes, and my application froze for 11-2 seconds.

How can I fix this issue?

p.s. My GPU is Intel HD Graphics 520, and current driver version is 20.19.15.4404
