Please, use at minimum 3 cables of each: o native DP connection o active DP-to-DVI adapter o two types of passive DP-to-DVI adapters And redo tests for use cases: [1] HSW UEFI BIOS + vBIOS + WIN7 = OK [2] HSW UEFI BIOS + vBIOS + WIN8.1 = OK [4] HSW UEFI BIOS + GOP + WIN8.1 = OK [6] HSW UEFI BIOS + GOP + F20 = FAILED Just to be sure if i915 kernel GFX driver is not on the timing edge (I expect that for [6] some use cases have chances to work)? You have everything in place, this will be +30 minutes to verify that [1], [2] and [4] work always, and [6] fails most of/ALL the time, so we eliminate cable electrical characteristics variations (same type of cables have slightly different characteristics, I know that from my Past)?
