ProBook is different from most competitors: HP is the only manufacturer that does not trust a high-quality IPS screen for its Full HD display, but usually installs the cheaper TN technology. The black level (0.61 cd / m²) and the contrast ratio (516: 1) are still quite correct when looking directly at the screen, but we will talk about it later. First, observe the color reproduction of the screen: the panel shows a massive bluish tinge and a high DeltaE compensation in the delivery status. Calibration dramatically improves reproduction and average DeltaE rates fall to exceptional levels of 1.1 (gray levels) and 1.7 (colors).
Unfortunately, the available color space only covers 75% of the sRGB standard, which is really insufficient for the professional edition of photos and images. Thanks to the antireflection surface of the screen and its maximum brightness of more than 300 cd / m², also available in battery mode, the ProBook can be recommended unconditionally for outdoor use. In particular, the Latitude E5470 is weak here. However, it is offered with a much brighter IPS panel for a fee. Finally, we will examine the main critical points of the 640 G2: insufficient stability of the viewing angle. The contrast and color accuracy rates mentioned above are only valid if you look at the screen at an absolutely right angle. Slight deviations significantly distort the image. If HP used an IPS panel like other manufacturers, the problem would be much less serious and the user would not have to adjust the angle of inclination permanently according to the current sitting position. Slowly but surely, the new generation Kaby Lake of Intel casts its shadow in front of her: the first ideas could already be presented from September. Until then, customers and manufacturers must be satisfied with Skylake’s current product line. HP has chosen the popular Core i5-6200U mid-range. Its two cores are between 2.3 and 2.8 GHz with Hyper-Threading (2 cores: 2.7 GHz). Being an ULV model, the 6200U is specified with a TDP of only 15 watts. In addition to the processor cores, the memory controller and the I / O interfaces, the chip (which is actually an MCM) also incorporates a graphics unit called HD Graphics 520. It is an average GPU expansion step (GT2) . ), runs between 300 and 1000 MHz and has 24 execution units (UE). The performance can even compete with some low-end dedicated accelerators based on the memory configuration. However, the manufacturer only installs a DDR4-2133 module with a capacity of 8 GB at the factory, which slightly reduces the performance of the graphics due to the resulting single-channel interface. A Samsung MGB 256 GB SSD is used as a storage device.
