On the inside, we have a good keyboard, once again similar to the larger devices, although it lacks the numeric keys, which is comtháng for a device of this kích thước. We still don’t lượt thích the layout of the arrow keys, as the up và down arrow are hugging on top of each other và are easily mistaken by feel. However, the touchpad is adequate và responsive sầu, as our favorite fingerprint reader, which is fast and super reliable. On the top side of the keyboard, under a grill, are placed the speakers of this 14-inch ProBook.


Moving to the sides of the notebook we are, once again, met by an exhaust vent, USB 3.0 Type-A, a tai nghe jaông xã & an SD card reader on the left, while on the right we have sầu the charging port, RJ-45 connector, followed by a đồ họa và HDXiaoMi MI port, as well as two more USBs, one of which is a regular Type-A, while the other one is Power nguồn Delivery and DisplayPort enabled Type-C.


Disassembly và maintenance

As every other device in the ProBook series, the fifth generation of ProBook 440 also has two service doors, which lead lớn every upgradable part of the machine. They are held in place by a single Phillips head screw (contrary khổng lồ the whole bottom panel held by torxes), và some clips.

You can see there is a lot of free space in our unit, since it lacks an SSD drive sầu, although featuring an M.2 slot which supports PCIe NVMe devices, and a Bluetooth không dây thẻ.

Display unique – FHD (1920 x 1080), IPS

The HP ProBook 440 G5 uses a Full HD (1920×1080) IPS panel with a Mã Sản Phẩm number AUO B140HAN02.1 (AUO213D). It offers 157 ppi and 0.161 x 0.161 mm px pitch. It can be considered as “Retina” when viewed from at least 55 centimet.

We’ve sầu recorded a peak brightness of 224 nits in the center of the screen & 209 nits as an average across the surface with 12% maximum deviation. The correlated color temperature at maximum brightness is a hair warmer than the optimal 6500K – 6340K & remains practically the same when we go along the grayscale – 6320K. You can see how these values change at 140 nits (81% brightness) in the image below.

The maximum color deviation dE2000 compared to lớn the center of the screen should be no more than 4.0 & if you are planning to lớn vì chưng color-sensitive work, it should be lower than 2.0. The contrast ratio is very good – 1230:1.

Our “Design và Gaming” profile delivers optimal color temperature (6500K) at 140 nits luminance & sRGB gamma mode.We tested the accuracy of the display with 24 commonly used colors like light & dark human skin, blue sky, green grass, orange etc. You can kiểm tra out the results at factory condition & also, with the “Design and Gaming” protệp tin.

The next figure shows how well the display is able to lớn reproduce really dark parts of an image, which is essential when watching movies or playing games in low ambient light.

The left side of the image represents the display with stochồng settings, while the right one is with the “Gaming và Web Design” protệp tin activated. On the horizontal axis, you will find the grayscale và on the vertical axis – the luminance of the display. On the two graphs below you can easily check for yourself how your display handles the darkest nuances but keep in mind that this also depends on the settings of your current display, the calibration, the viewing angle and the surrounding light conditions.

PWM (Screen flickering)

Pulse-width modulation (PWM) is an easy way to control monitor brightness. When you lower the brightness, the light intensity of the backlight is not lowered, but instead turned off and on by the electronics with a frequency indistinguishable to the human eye. In these light impulses, the light/no-light time ratio varies, while brightness remains unchanged, which is harmful to your eyes.You can read more about that in our dedicated article on PWM.

HP ProBook 440 G5’s display brightness is not PWM-adjusted throughout all brightness levels, rendering the screen suitable for extended periods of usage without harassing your eyesight in this aspect.

Blue light emissions

Installing of our Health-Guard protệp tin not only eliminates PWM but also reduces the harmful Blue Light emissions while keeping the colors of the screen perceptually accurate. If you’re not familiar with the Blue light, the TL;DR version is – emissions that negatively affect your eyes, skin & your whole body. You can find more information about that in our dedicated article on Blue Light.You can see the levels of emitted blue light on the spectral power distribution (SPD) graph.

Conclusion

The Full HD IPS panel used in the HP. ProBook 440 G5 is excellent, as it has an excellent contrast ratio, as well as comfortable viewing angles & adequate mặc định settings. Another positive about this panel is that it doesn’t use PWM at all for controlling the levels of brightness. The only drawbaông chồng we were able khổng lồ find is the disability to lớn display basically half of the colors of the sRGB color space.
