More expensive as compared to what?
If you are talking about the Korean monitors then go and have a look at the prices (including duty which is not shown in the price on that auction site). But, when you look for a comparable monitor then you will have to look for one that has
- Input Signal: HDMI, DVI-D, DP (Display Port), VGA (D-sub 15pin)
as that is what the DGM monitors have
Also, a lot of the Korean monitors are A- rated panels which will be rejected by the likes of Apple, Dell and HP as they will have some kind of defect (my monitor is ever so slightly brighter on the left hand side). Are the DGM monitors A/A+ panels or A- like most of the cheap Korean monitors?
The panels in the DGM are purchased from LG and are A+ panels, I confirmed this before buying and negotiated the 3yr warranty.
