Quote from Sirry : Can someone please reiterate the differences between one of the cheaper Korean IPS monitors and this, again? Thanks!

Wide gamut support. If you are a photography/digital art enthusiast or pro then you'll likely want Adobe RGB color space support. sRGB, or "normal gamut" is an old standard that was designed for CRT monitors. It is a limited color space that doesn't display nearly as much as the human eye can see, especially in the green range.

Matte coating. Most of the Korean models are glossy because it's cheaper to make glossy screens.

Uses fluorescent backlight not LED, so potentially less harmful UV and blue-violet light and less peaking.

Moreover, PWM (pulse-width modulation) in a CCFL monitor is less straining on the eyes (flicker) than for LED backlights that use it because LED turns on and off very quickly with no gradual darkening and lightening like CCFL. Some LED backlights don't use PWM but most do.

Likely to have better backlight uniformity, rather that bright and dark spots, since it doesn't use edge LED lighting. More expensive LED lit panels tend to have more consistent uniformity than inexpensive IPS edge-like models.

Downsides to CCFL are less stability over time (requiring the use of a hardware colorimeter to recalibrate periodically) and more power usage.

12-bit hardware LUT. This helps when using a colorimeter because you lose less of the monitor's gamut (not relying solely on software).

Better stand.

Factory calibration for Adobe RGB that is quite good, lessening the need for a hardware colorimeter.

Factory calibration for sRGB isn't so accurate, so better to use colorimeter.

More ports. (2x DVI, HDMI, DisplayPort, VGA, component. composite)

True 8-bit color plus 2 bits of dithering for pseudo 10-bit. This should result in less banding and noise than a 6-bit monitor with 2-bits of dithering, which is common for cheaper panels.

OSD (on-screen display), with a variety of settings and adjustment options. Some Korean panels have no OSD.

Easier/better return policy and warranty.

Improvements may be made to firmware on Dell.

Some of the Korean panels may have less input lag due to fewer ports and/or less processing overhead.
