With WQHD being mislabled as 2K, I thought it couldn't get any dumber but INNOCN proved me wrong.
But fear not, I have a solution. DQHD shall henceforth be referred to as 5K1K.
So far, only laptop screens, which are neither QD- nor W-OLED, fulfilled the requirements for anything higher than DisplayHDR 400 TB. It wouldn't surprise me to see laptops hit DisplayHDR 1000 TB first, given the 1000 nits at 100% APL of the iPad's tandem panel.
According to HWiNFO, my 7800X3D applies a multiplier of 47 during the preparing phase and 47.3 during rendering.
However mine also runs at 103 MHz eCLK, 2133 MHz FCLK and I had my daily stuff running in the background.
Apparantly a stock 7800X3D would run it at 4.8 GHz.
