When it comes to the various PG32UCDM models, nobody should be caring about getting something so expensive that also creates a handicap with DSC. And knowing that, ASUS should stop trying to take advantage of their customers by making excessive extra costs for the varients worth buying like the PG32UCDMR or PG32UCDM3 which cost them pennies on the dollar difference to make.
TL/DR: The siblings of this model justify THIS advertised price, not the weakest of the bunch, so at this price for this model, nobody should care about it.
