the biggest takeaway from my side-by-side comparison wasn’t that the Dell was superior; it was how incredibly narrow the gap is between the two displays, given their respective prices. The 27-incher may not be as large, but it still gives you that sense of freedom that comes with expansive display real estate. And you wouldn’t notice any weaknesses in the 27” monitor’s color tuning or temperature without seeing the two displays side by side. When I moved the Korean monitor to another table against an adjacent wall, any sense of iffy white balance evaporated instantly.
this monitor doesn’t support HDCP, the copy-protection scheme for high-def digital displays. Even the Dell 30”, with no scaler ASIC, offers HDCP support. What that means is that certain copy-protected content, including commercial Blu-ray discs and some protected cable TV programs, can’t be played back on this display.
