![]() The thing that finally got me where I want to be was modifying the hackintool produced override - using AWEDIDEditor. hackintool empties the extension block but it is still there, injects apple info, changes the info, including the aspect ratio to that of the apple display, nightshift works, acrobat scales badly. I dont recall if the acer was still marked as a television. patchedid strips the cea extension block completely, does not inject apple info, and keeps the colorimetry and aspect ratio from the real acer edid, it doesn't fool macos into giving me nightshift. However as far as I could tell, this was not the cause of my nightshift failure. the samsung DOES support RGB, YCC444, but not YCC422. I noticed there are several things going on. IS marked as Television in system informationĪcer 382 (patch-edid override, forces RGB and strips all CEA extension blocks)Īcer 382 (hackintool override, forces rgb, and injects imac 27" retina info), DP RVIIīUT Adobe Reader renders documents stretched horizontally. not marked as Television in system information I compared EDID data for the following, for clues as to what apple is looking for for nightshift - color capability flags was my guess: When both are connected, nightshift controls appear on the samsungs system pref pane, and nightshift only applies to the samsung. I verified nightshift was working/enabled by macos - works on a cheap samsung 1366x768p tv. I have been looking into getting nightshift working, but I have one of these ultrawides - a 38" 3840x1600 75Hz Acer XR382cqk, that doesn't have an aspect ratio that matches any apple displays. In this way, non 16:9/10 ratio monitors will be supported properly. ![]() These are byte 21 and 22 (starting from byte) in the EDID. Some applications clearly care about these fields - Adobe Acrobat Reader DC was the one I found. hackintool should "maintain aspect ratio" by NOT modifying certain EDID fields when injecting apple display infoīasic Display Parameters->Maximum horizontal image size and Maximum vertical image size Monitor and pixel aspect ratio are treated fine everywhere except Acrobat Reader DC.Ĭolor capability may have been a red herring on this monitor.ġ. I succeeded but I noticed aspect ratio not being treated correctly in Acrobat Reader DC - document is rendered stretched horizontally by the difference of real 12:5 vs overridden 16:10. ![]() Tried to get Nightshift going on 3840x1600 monitor, You willing to discuss EDID / CEA Extensions regarding the Display Overrides generated by hackintool? Sorry if this is not the right place. ![]()
