DDM has never been supported with Alienware Nvidia G-Sync models (AW2518H, AW2521H, AW2721D, AW3418DW, AW3420DW, AW3423DW, AW3821DW) due to compatibility issues with the advanced built-in Nvidia G-Sync module.DDM is supported with Alienware AMD FreeSync models (AW2518HF, AW2521HF, AW2521HFA, AW2521HFL, AW2521HFLA, AW2523HF, AW2720HF, AW2720HFA, AW2723DF, AW3423DWF, AW5520QF) that use the standard FreeSync module.

AW3423DW is the great monitor. But without the support of DDM 2.x , I cannot set the daylight mode and the night mode about the brightness and contrast. It's very very  inconvenient.
AW3423DW, why DDM 2.x not supported?
