![]() ![]() What we see here is a great potential from the cooling solution. The first column shows a computer’s reaction to a short load (2-10 seconds), the second column simulates a serious task (between 15 and 30 seconds), and the third column is a good indicator of how good the laptop is for long loads such as video rendering.Īverage core frequency (base frequency + X) CPU temp. In this test we use 100% on the CPU cores, monitoring their frequencies and chip temperature. You can check out the results at factory condition and also, with the “Design and Gaming” profile.īelow you can compare the scores of Acer Predator Helios with the default settings (left), and with the “Gaming and Web design” profile (right). We tested the accuracy of the display with 24 commonly used colors like light and dark human skin, blue sky, green grass, orange, etc. Our “Design and Gaming” profile delivers optimal color temperature (6500K) at 140 cd/m2 luminance and sRGB gamma mode. Its display covers 92% of the sRGB/ITU-R BT.709 (web/HDTV standard) in CIE1976. The yellow dotted line shows Acer Predator Helios 300 17 2019’s color gamut coverage. We’ve also included the so-called Michael Pointer gamut, or Pointer’s gamut, which represents the colors that naturally occur around us every day. Rec.2020, however, is still a thing of the future and it’s difficult for today’s displays to cover that well. Still, we’ve included other color spaces like the famous DCI-P3 standard used by movie studios, as well as the digital UHD Rec.2020 standard. ![]() Basically, colors inside the black triangle are used by everyone and this is the essential part of the color quality and color accuracy of a mainstream notebook. 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 in 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. The contrast ratio is good – 1290:1 (1260:1 after profiling). 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 (a maximum tolerance of 2.0 ). The illustration below shows how matters are for operational brightness levels (approximately 140 nits) – in this particular case at 43% Brightness (White level = 140 cd/m2, Black level = 0.11 cd/m2). In the illustration below you can see how the display performs from uniformity perspective. The average color temperature through the grey scale before profiling is 7050K as well. The Correlated Color Temperature on a white screen and at maximum brightness is 7050K (average) – colder than the 6500K optimum for sRGB. The maximum measured brightness is pretty high – 318 nits (cd/m2) in the middle of the screen and 316 nits (cd/m2) average across the surface with a maximum deviation of only 4%. We have provided images at 45 degrees to evaluate quality. ![]() The screen can be considered Retina when viewed from at least 69 cm (from this distance, the average human eye can’t see the individual pixels). Additionally, the screen ratio is 16:9, the pixel density – 127 ppi, their pitch – 0.1995 x 0.1995 mm. Acer Predator Helios is equipped with a Full HD IPS screen, model number AUO B173HAN04.2 (AUO429D). ![]()
