Windows 10 20H2 (Build 19042.870) with nVidia GeForce GTX 1650 Graphics. All MS updates installed & all system updates are current as well. We had no issues prior to installing the Blank Screen fix. Same setup on 25 other computers.
OK, thanks for confirming. If you do not need screen blanking in effect you should be able to temporarily disable the LMI driver responsible in order to improve the performance. We are currently investigating the cause of this behavior.
