I have the 1015 on it and an MSI MPG Z790 with 4090RTX via DisplayPort. I still get a screen tear every 1-5 minutes that drives me to despair. The only workaround is to program 2 settings on the pre-selection buttons: 1. fix 120Hz for working and 2. with VRR for gaming. The screentear is relatively absent in the game, as it rarely occurs. When working, however, it is always clearly visible and disturbing.
I can't tell yet, but interestingly "Auto" now seems to dim much more than "Low" or even "High" especially in SDR mode.
Unfortunately, the scanlines in HDR and darker picture content are still not gone. The screen was reset after the firmware update and disconnected from the power supply.
