There are multiple panels with which Interlace mode is seen to cause flickering (interlacing artifacts) with different platforms. The issue is seen with both HDMI, DP with CML, CFL, ICL, EHL with different display models from Acer, Benq, Dell etc. There are some models where the issue is not seen with same setup. Due to this, cases where multiple display are configured in clone mode, sometimes interlaced mode gets picked up in one of the displays and flickers are seen. Since its difficult to pin point if issue is due to the HW or due to panels, removing interlace mode for DP and HDMI till this is root caused.
