Display, power consumption, dimensions, technologies used, connections, certifications, comfort features. All these keywords can be relevant for a purchase decision, but an exact comparison is often difficult. For this reason, we will summarize as many of the mentioned specifications as possible in an understandable form in the course of this article. Let's start with the most important component of the 258B6QJEB from Philips.
Display
Texts, videos and/or other applications can be displayed on the 25 inches ( 63.4 cm on the diagonal) of the monitor. Let's keep it short and sweet. The monitor has an aspect ratio of 1.778 : 1. In addition to the aspect ratios and the specified screen diagonal, the ratio between the monitor surface and the actual display could also be relevant for some enthusiasts. This ratio represents the general relationship between non-display and display. In other words: Approximately 87.5 % of the front surface of the monitor consists of the display, while the remaining percent consists of screen edges and is not suitable for image reproduction. If you want to place several monitors next to each other, you should make sure you choose models with the narrowest possible edges. The display is a AH panel. The panel has a resolution of 2560 x 1440 px. The pixel density is 117 ppi. The pixel pitch is 0.216 mm. The continuous possible brightness specified by the manufacturer Philips is 350 nt. The panel is illuminated by W-LED. The built-in panel ensures stable color reproduction of the image, even at deviating viewing angles, by means of its 178 ° (horizontal) viewing angle. Philips promises stable color reproduction moreover within a 178 ° vertical angle. The refresh rate is horizontally seen at the 258B6QJEB 30 khz to 83 khz. Vertically, however, the image renews at a minimum rate of 56 hz up to 76 hz. The minimum response time of the monitor is ms. The average response time of the monitor is about ms.
Color space
The panel has a bit depth of 8 per color channel, but what does that mean? The number of bits determines how many colors can be encoded for the individual pixels of the display. For an 8-bit panel, for example, this is 256 different colors (2^8 = 256). However, since we usually display three different colors per pixel at the same time, in theory about 16 million (256^3) different colors are possible by mixing the three pixels. A 10-bit panel could even display a billion colors. According to the manufacturer, the coverage of the SRGB color space is 97 %.
Contrast ratio
Contrast ratio is a common measurement used to represent the maximum relative differences in brightness between black and white. It describes the ability of a screen or projector to produce a high-contrast image and is the quotient of the maximum and minimum displayable luminance. The higher the values are away from each other, the stronger the quantitatively seen difference between black and white is set up, which in turn results in an improved image quality. This monitor from Philips has a static contrast ratio of 1000 : 1 , according to the manufacturer. In contrast to the static contrast ratio, the dynamic contrast ratio changes the brightness of the panel itself in addition to the difference measurement from black to white. In addition to the difference between the brightest and the darkest pixel, the backlight is thus changed. Since the brightness of the panel may not be able to be adjusted exactly to a single pixel, a so-called halo effect is possible. The value of 20000000 : 1 of dynamic contrast ratio for the monitor 258B6QJEB cannot provide any information about the severity of the halo effect here. Therefore, it is more useful to compare the static contrast ratio. The monitor from Philips supports adaptive contrast management, dynamically adjusting the contrast ratio of the input signal to ensure razor-sharp image displays. Each scene is continuously analyzed by 258B6QJEB and the images are adjusted accordingly frame by frame. This analysis and dynamic adjustment of contrast is designed to enhance color quality and provide better black levels when displaying dark scenes and shaded/dark image sequences.
HDR
The monitor supports all HDR modes listed here:
screen design
The following dimensions must be planned for a free-standing stand without attached feet/stand: 34.4 cm x 57.1 cm x 5.5 cm (HxWxD)
The size of the 258B6QJEB on the desk is likely to be particularly relevant for most users. Philips specifies a space requirement of 51.1 x 57.1 x 24.4 cm (HxWxD) with the included stand. If you want to place the monitor on a table or even transport it, you should expect a weight of 7 kg with the stand screwed in. The monitor 258B6QJEB without the stand weighs 4.66 kg. This weight reduction should be taken into account for wall or arm mounting, since monitor arms have a maximum load capacity. Speaking of weight without a stand and thus wall or table mounts. The monitor supports a Vesa mounting. A height-adjustable stand ensures an improved ergonomic posture during use. The monitor can be moved to a maximum height of 13 cm. This value is always measured from the bottom edge of the screen.
Rotate, tilt and swivel
The monitor from Philips has a pivot function and can thus be rotated using the included stand. A rotation to the left is possible with up to 0 degree. To the right, the monitor can be rotated by 90 degree. The 258B6QJEB can be swiveled when mounted on the included stand. Pivoting to the left is possible up to 65 degree. Pivoting to the right is possible up to 65 degree. The monitor 258B6QJEB offers the option of adjusting the tilt as required to create an ergonomic working environment and reduce visual fatigue. The angle of inclination to the rear is 20. The monitor can be tilted forward by 5 degree.
Ports
The monitor can be connected via 1 VGA ports.
camera
This monitor does not have a camera.
Loudspeaker
The monitor from Philips has integrated speakers, for playing sounds, music or speech. The sound is emitted via 2 speakers, which are integrated into the device. Each of the built-in speakers has a contingent of 2 w power.
Features
- Flicker Free: Philips 's Flicker Free technology minimizes distracting screen flicker, allowing you to work and/or play longer without restrictions.
Panel manufacturer
Many manufacturers of monitors and TVs fall back on third-party manufacturers, such as Samsung or LG, when choosing the actual display (panel). Thus, many of the monitors have the same panel and, conversely, differ only in their design, additional functionalities, the software used and, of course, the price. Two monitors from Philips or another manufacturer with an identical panel do not necessarily have to have the same picture quality, but it is usually a first indicator for a purchase decision. The panel used here is originally from LG Display and has the model number LM250WQ1-SSA1.
WiFi / Bluetooth
Power consumption
The average consumption was given by Philips as 24.6 w. The maximum power consumption (peak) specified for this monitor is 40 w. In standby mode, the device consumes approximately 0.5 w. When switched off, on the other hand, the monitor consumes only 0.3 w. In ECO mode, the monitor consumes 18.9 w. The monitor can be operated on a 110v power supply. The monitor can be operated on a 220v power supply. The power grid has to supply a frequency of 50 hz to 60 hz.
Environment
The maximum height at which the monitor may be operated, according to the manufacturer's specifications, is 3.658 km. During operation, the ambient temperature must not exceed 40 °C , to ensure full functionality. Below a temperature of 0 °C , the monitor from Philips should again not be used. The humidity must not exceed 80 percent. At least, however, 20 percent humidity. The monitor may be stored at a maximum humidity of 80 percent. The minimum humidity during storage should not fall below 20 percent. The maximum storage temperature should be according to Philips 60 °C. Minimal were given by Philips -20 °C. According to the manufacturer, the monitor may be stored at a maximum height of 12.192 km.
