My Dell E248WFP did not appear dark to me when I first connected it, if anything it was too bright overall. The backlight I mine appears evenly distributed with minimal bleeding. No dead pixels or any other anomalies that I can tell. The primary thing that really bothered me about this monitor out of the box is that all of the preset color settings I tried made the greens and reds appear abnormally bright, almost neon color.
To get the color settings to an acceptable level I had to first select the user adjustable settings and I set: red-96, green-95, and blue-100. After setting the color levels I selected the sRGB preset on the menu. I actually (temporarily) have an LG L227WTG for comparison testing. After setting up the monitors individually on my computer to my liking, I connected both of them at the same time so I could do a side-by-side comparison. I found that after adjusting the Dell E248WFP to the settings listed above it was VERY close in color to the LG.
The primary difference is of course the glossy screen adds a bit of contrast or color ?pop?. The second difference is that SOME of the reds on my Dell E248WFP appear to be darker, almost like they are missing some orange tones. I am willing to live with the slight variation in the reds for the additional screen space.
Both monitors were connected to an EVGA 8800GTS 512 via DVI connectors at their native resolutions. So in conclusion, there are two things I don?t like about the monitor.
1) Some of the red tones are slightly darker than they should be.
2) There is no 1:1 pixel mapping.
