中国Great color accuracy on the Dell Latitude 14 7420 with the help of our Gaming and Web design profile
Business laptops aren’t usually known for their superb color reproduction. However, the premium segment is starting to catch up and with hardware getting more and more powerful, suddenly devices can get very versatile and serve different purposes with just the addition of a good display. The Dell Latitude 14 7420 is one such case. It comes with the new Tiger Lake CPUs which offer both decent performance and great power efficiency. To add even more it has a good enough display to handle some artistic work, or any color-sensitive work for that matter, especially when you use our Design and Gaming profile.
Dell Latitude 14 7420: Full Specs / In-depth Review
Display quality
The Dell Latitude 14 7420 comes with a 14-inch Full HD IPS panel with comfortable viewing angles, a great maximum brightness of 435 nits in the middle of the screen, and 414 nits on average across the entire area of the screen, which calculates to a deviation of 9%. The contrast ratio is also spectacular, sitting at 1800:1. The color coverage is also quite good, with the panel covering 90% of the sRGB color gamut.
What is even better though is the color accuracy, which with the factory settings (left) has a dE value of 5.4, way off the standard. When you apply our Design and gaming profile (right), the dE value goes down significantly, down to 1.2.

Hi, thanks for the thorough review. According to the specs provided by Dell, the 400 nits FHD screen has a contrast ratio of merely 600:1, which is really low for a premium line. So pleased to see a 1800:1 was measured here since I planned to purchase one recently. Could Dell make a mistake providing wrong numbers?
