AmLED is just AUO's marketing term for mini-LED.It is a different panel. AmLED according to AUO. Wouldn't be surprised if in the future newer versions of AmLED have more dimming zones and 576 is just the starting point followed by 1152, 2304, 4608 etc. Also regarding the Alienware, this is nothing but baseless speculation on my part but I think the Gsync module pretty much added nothing to that monitor (it couldn't even solve VRR flickering) while on a FALD LCD the module is now responsible for controlling the FALD algorithm, variable OD, etc all making sure it works together. So maybe that Gsync module is more expensive because it does more complex things compared to the one found in the Alienware which seems to do nothing as there is no local dimming to control and OLEDs do not need overdrive. Again I have no proof of this just baseless speculation.
