I have a Lenovo X1 Yoga 3rd generation that is as up-to-date as it can be. All drivers have been checked and rechecked. A phone call to Lenovo support could not provide any answers. the problem started when I updated Adobe Premiere Pro to its current release as soon as the program is started, a notification that states that my video driver is unsupported.
Intel has an available driver update, but being I have a Lenovo laptop under warranty and is supported by Lenovo, that drive is not compatible with my machine. An updated driver must come from Lenovo rendering the most current release of Premiere Pro inoperative.
I have done this as a temporary solution. Uninstall the Premiere version 14.5 and reinstall the 14.4 version. This attempt did not work, and I still have a video display driver problem.
I believe you'll need to continue using older versions of Premiere as the iGPU cannot be updated to the required drivers for the newer versions of Premiere. But I yield to the more hardware-savvy members of the forum here.
