    Phoronix: Linux 5.4 Bringing Support For Lenovo's "PrivacyGuard" On Newer ThinkPads

    Newer high-end Lenovo ThinkPad laptops feature an option called "PrivacyGuard" for restricting the usable vertical and horizontal viewing angles of the LCD display, similar to what has been achievable previously using film covers and the like. With Linux 5.4 this feature will be supported by the kernel if concerned about others looking over your shoulders at your screen, etc...

      I'm holding off the buy because new APU will come in the next 6 months, with Zen 2 and all the sparks, and my old trusty Ivybridge can handle until then

        Wait so TN/IPS is capable of tweaking the viewing angle now?

          It's rather a separate layer on top of the display layer.

            I wonder if anyone will ever implement HP SureView support?

              tildearrow - I was wondering about that too. TN panels provide this functionality for free, thanks to bad viewing angles. I thought at first it was switching between TN and IPS panel type.

                Please quote. I don't subscribe to threads and hence I never knew you replied.
