1. HP usually has a nasty feature that will re install your original HP graphics driver no matter if you clean with DDU. This will normally break drivers. 2. Yes same thing 3. Please no driver update utilities. Always pick the right driver for your card manually. 4. You can get official ones from AMD : ) 6. Indeed The reason I suggest going the official route first is to make sure that you establish a clear picture on what might be working or not. .. In case some strange featurecreep/ or bug from the UnifL package makes its way into the config. FeatureTestControl can be a tricky thing. However if you follow my advise on installing original Intel HD 4000 drivers from Driver Station, then you might get lucky. The FTC value gets set by the Intel driver.
