    Dithering, color banding using HD Graphics 4000 on lenovo thinkpad t530

    Bobbobbob2016

      Hi there,

       

      [My problem]

      Gradients look bad on my laptop. "Bad" as in "color banding", "very strong dithering", especially when subtle gradients are involved.

      I use both the internal display and an external samsung SyncMaster T220, conncted with VGA. (The external Syncmaster did not show the error on my old laptop.)

       

      [Details]

      This happens systemwide, from desktop background to newly generated images in photoshop.

      I already updated my graohics driver via windows hardware manager and rebooted.

      I also executed the Lenovo Sytem Update tool, which updated my BIOS, and rebooted.

       

      What are my options here?

       

      [Setup]

      graphics adapter = Intel(R) HD Graphics 4000

      driver version = 10.18.10.3621

      driver date = 17.05.2014

      Windows 8.1. Pro 64 Bit

      Lenovo Thinkpad T530

       

      Thanks a lot for any advice!

      Bob
