Today we will look at the monitor 438P1 from Philips from the year 2020. Within this article, we will first take a closer look at the most important feature of a monitor -the display-, then the design, and in the next section we will go into the features of the monitor. Of course, power consumption, certifications, connectivity and other important details will also be considered.
Display
Let's start with the size of the display. It is 42 inches ( 1.08 m on the diagonal) large and should thus offer enough space for all contents according to Philips. Television screens and monitors usually have an aspect ratio of 16:9 (approximately 1.78:1). More rarely, computer monitors are also found with an aspect ratio of 16:10.
Ultrawidemonitors are often manufactured with an aspect ratio of 21:9 (approximately 2.34:1). They are mainly used for computer games and as an alternative to two side-by-side screens. The first devices of this type came onto the market around 2014. Against this backdrop, the monitor 438P1 from Philips faces an aspect ratio of 1.778 : 1. Around 96.8 % of the front surface of the monitor consists of the display, while the rest is made up of screen edges that cannot display images. If you want to place several monitors next to each other, it is advisable to prefer those with narrow edges. The display is a IPS panel. The panel has a resolution of 3840 x 2160 px. The pixel density is 103 ppi. The pixel pitch is 0.245 mm. The continuous possible brightness specified by the manufacturer Philips is 400 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 438P1 30 khz to 140 khz. Vertically, however, the image renews at a minimum rate of 23 hz up to 75 hz. The minimum response time of the monitor is ms. The display panel is Anti-glare/Matte (2H).
Color space
The panel has a bit depth of 10 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 NTSC 1953 color space is 88 %. According to the manufacturer, the coverage of the SRGB color space is 102 %.
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 1200 : 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 50000000 : 1 of dynamic contrast ratio for the monitor 438P1 cannot provide any information about the severity of the halo effect here. Therefore, it is more useful to compare the static contrast ratio.
HDR
The monitor supports all HDR modes listed here:
- HDR 400
screen design
Philips Specifies the following dimensions for the monitor 438P1 without stand/feet: 52.9 cm x 97.3 cm x 6.4 cm (HxWxD)
If you want to place the monitor described here on the desk without a wall mount, you should allow for 63.3 x 97.3 x 25.9 cm (HxWxD) of space. The device weighs 11.78 kg with the stand in place. Without stand, the monitor weighs 11.06 kg. Speaking of weight without a stand and thus wall or table mounts. The monitor supports a Vesa mounting.
Rotate, tilt and swivel
The monitor from Philips cannot be rotated. The monitor cannot be swiveled. This feature could be retrofitted with a third-party stand. A tilt function was not provided by Philips with the included stand.
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 5 w power.
Features
- Flicker Free: Philips 's Flicker Free technology minimizes distracting screen flicker, allowing you to work and/or play longer without restrictions.
- Picture by Picture mode
- Picture in Picture mode
- Integrated KVM Switch
- The display/monitor supports Frame Rate Compensation.
Anyone who works a lot on the computer spends many hours a day in front of the screen. Excessive screen work can damage the eyes. This effect can be particularly pronounced during the darker hours and in the winter months. Many monitor manufacturers have now reacted and offer technologies and settings to reduce the blue component, which is primarily controversial. Depending on the manufacturer, these can be called "Low Blue Light", "Low Blue Light Technology", "SoftBlue" or even "Eye Saver Mode" and function differently. However, it is only important that Philips offers a technology to reduce the blue content in its monitor 438P1. The Adaptive Sync feature of the 438P1 dynamically varies the monitor's refresh rate and responds to the game's required frame rates.
WiFi / Bluetooth
Power consumption
The average consumption was given by Philips as 100 w. In standby mode, the device consumes approximately 0.3 w. In ECO mode, the monitor consumes 53.3 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.
Packaging
The monitor is packaged in a cardboard box measuring 68 x 1.07 x 18.6 cm (height x width x depth). The box together with the monitor weighs about 14.74 kg.
