![]() As for the Adobe RGB, this is used in professional cameras, monitors, etc for printing. Inside the black triangle, you will see the standard color gamut (sRGB) that is being used by millions of people on HDTV and on the web. To start, there’s the CIE 1976 Uniform Chromaticity Diagram that represents the visible specter of colors by the human eye, giving you a better perception of the color gamut coverage and the color accuracy. To make sure we are on the same page, we would like to give you a little introduction to the sRGB color gamut and the Adobe RGB. Values of dE2000 over 4.0 should not occur, and this parameter is one of the first you should check if you intend to use the laptop for color-sensitive work. In other words, the leakage of light from the light source. In the illustration below you can see how the display performs from a uniformity perspective. The Correlated Color Temperature on a white screen is 7270K – virtually matching the sRGB standard of 6500K, which is great. The measured maximum brightness of 252 nits in the middle of the screen and 242 nits as an average for the whole area, with a maximum deviation of 11%. We offer images at 45° to evaluate image quality.Īlso, a video with locked focus and exposure. The screen turns into Retina when viewed at a distance equal to or greater than 60cm (24″) (from this distance one’s eye stops differentiating the separate pixels, and it is normal for looking at a laptop). ![]() The screen ratio is 16:9, and we are looking at a pixel density of – 142 ppi, and a pitch of 0.18 х 0.18 mm. Its diagonal is 15.6″ (39.62 cm), and the resolution is 1920 х 1080 pixels. HP ProBook 455 G9 has a Full HD IPS panel with a model number BOE BOE09D8. The hot air, respectively, exits the machine through a vent on the back. Turn the laptop upside down, and you won’t be surprised to see only a ventilation grill. It offers really smooth gliding, very accurate tracking, and super responsive input. Surrounded by the palm rest area is the touchpad. It also has its speakers above the keyboard, whereas the fingerprint reader is located below the right “Enter” key. It has a backlight, NumberPad, spill-resistance, long key travel, and very clicky and consistent feedback. However, the one on the ProBook 455 G9 is almost unmatched, except for some ThinkPads. Lately, we feel like we’ve been saying that a laptop’s keyboard is good for typing quite often. Once you do that, you will see slim bezels, with the top one featuring an HD Web camera with a privacy shutter above it, and an optional IR face recognition scanner. ![]() Here, the lid can be opened with a single hand. ![]() Thankfully, this makes it comfortable for your wrists. Its design features smooth edges on the base and the lid, and pretty sharp cut-offs on the bottom. This makes it really sturdy with very little flex in either the lid or the base. Furthermore, the entire device is made out of metal. This means that it still weighs 1.74 kilos, and has a profile of nearly 20mm. As we said, the body of this device hasn’t changed from last year. ![]()
