Question Getting random black screen on Alienware AW2720HF monitor ?

Aug 17, 2021
I bought an Alienware AW2720HF about a month ago from Best Buy. It worked fine with no issues until today the screen went black. There is an IPS glow but, neither the logo nor the OSD will display with or without a pc.
The power indicator will come on, and if connected through HDMI, The PC detects it. However, it returns to the same IPS Glow. When monitor settings are changed, it will go flat black and then return to the glow.
I have tried two different pcs and have gutted both. The problem has to lie in the monitor or the power supply. Does anyone have any recommendations?
