Reviews for the Dell Latitude 14 7440, i7-1355U
Dell Latitude 14 7440 review – stylish laptop with good cooling solution
Source: Laptop Media
EN→zh-CN
The Dell Latitude 14 7440 is a small laptop that performs well. The cooling solution has just one big fan and a single heat pipe, but that’s enough for a 2.63 GHz P core clock under heavy CPU usage. This is a very good result for a light 14-incher. Moreover, the fan isn’t noisy and the keyboard doesn’t feel too hot to the touch when the processor is tortured with Prime95. The 14″ 16:10 1200p display has a ridiculously long name – LG Display TDVNC-140WU2 (LGD06F9; LP140WU2-SPM1). Aside from that, it’s PWM-free and the viewing angles are good. Still, the sRGB coverage and the color accuracy are nothing to write home about which is normal for an office device that isn’t meant for professional color-sensitive work. The battery life impresses us – more than 14 hours of Web browsing on a single charge. Our machine has the optional 57Wh model, if you pick a notebook with the default 38Wh unit and a 28W P-series CPU, maybe the autonomous life will be shorter. Just like many other compact laptops, the memory is soldered.

大体上，这个屏幕尺寸常见于亚笔记本电脑，超极本和变形本中。对这三类产品来说这个尺寸都较大。亚笔记本中尺寸最大的机型是采用这个屏幕尺寸。
大尺寸可以让屏幕有更高的分辨率。因而例如字体等的细节将会更丰富。不过另一方面，小屏幕的功耗会较低，而设备也会更轻盈小巧，售价更低。
