Hello.
I have two 2k monitors, the main one is 2560x1600(Dell u3011), the 2nd one is 2560x1440(Eizo sx2762w).
My 6800 draws 35-40w power while idle.
It drops to 6-9w when I lower the u3011 resolution to 2048x1534 or 1080p.
My card is RX6800 Reference Edition
Driver version is 31.0.12027.7000 (auto installed by Win11)
