Like most things however, there's more to the next-gen Dell display than meets the eye
Dell this week announced a brand new 24-inch LCD monitor based on traditional cold cathode fluorescent lamp (CCFL) backlights. Unlike other panels from Dell however, the new 2407WFP-HC boasts what Dell dubs as TrueColor (translated) technology, giving the 2407WFP-HC a greater color gamut than traditional LCD panels.
Dell's current Ultrasharp 2407WFP is also based on CCFL technology. Dell calls the backlight technology on the 2407WFP-HC "wide CCFL" technology -- essentially indicating a wider color gamut. Most LCDs can display between 40-percent and 70-percent of the NTSC color gamut. With TrueColor technology, Dell claims that the 2407WFP-HC is capable of displaying 92-percent of that color space.
The following are some specifications of the new Ultrasharp 2407WFP-HC:
- Resolution: 1920 x 1200
- Response time: 6ms
- Contrast ratio: 1,000:1
- 9-in-2 media card reader integrated into bezel
- 4 USB 2.0 ports
Despite the increased color gamut, TrueColor does not necessarily give users increased color accuracy. In fact, to obtain a higher level of color accuracy, users will still have to calibrate their displays with devices like the ColorVision Spyder.
Most manufacturers today report color gamut using % NTSC, including Dell. Unfortunately % NTSC is calculated based on the area of two gamut triangles and not on actual coordinates -- a ratio that does not equate to image quality. Having a higher % NTSC is less important than having the ability to cover colors that are perceptually more important to overall image quality since not all colors are important. As a result, displays with a smaller % NTSC color gamut can actually outperform displays with a greater % NTSC gamut.
While TrueColor increases the gamut for CCFL displays, there is another technology already on the rise: LED-backlighting. One of the many areas where LED-backlighting outperforms CCFL is in white point and brightness -- two critically important factors in determining color accuracy. Without this accuracy, two displays with the same % NTSC rating may not display the same colors.
The new Dell Ultrasharp 2407WFP will be available in July at a price of $679. The company began shipping the 30" wide gamut 3007WFP-HC this past spring, but did not officially announce the model.
