Lately I have been asked about Video issues in Lync and R2 Communicator – Communicator freezes once you accept inbound video call.
I did search the net, and came across the following article written by Chad McGreanor – thanks 🙂
This issue are related to the nVidia display driver with Lenovo T420s, T520 & W520.
Lenovo has been working on updating their site with the current Nvidia drivers, but as far as I know – It’s not updated yet !
Go to Nvidia directly and download the current driver that solves this issue.
After upgrading nVidia drivers, everything works 🙂
