HP Z38c

Product image for Z38c

Today we will look at the monitor Z38c from HP from the year 2017. 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

The monitor belongs to the device class 37 inches ( 95.2 cm on the diagonal). While classic CRT monitors were built with a screen ratio of 4:3, this monitor has a ratio of 2.4 : 1 (width to height). In addition to the aspect ratios and the specified screen diagonal, some enthusiasts may also be interested in the ratio between the monitor surface and the actual display. This ratio describes the general relationship between non-display and display. In other words, approximately 90.7 % of the front surface of the monitor consists of the display, while the rest consists of screen edges and cannot display an image. When setting up several monitors next to each other, it is advisable to give preference to models with the narrowest possible edges. The display is a AH panel. The panel has a resolution of 3840 x 1600 px. The pixel density is 110 ppi. The pixel pitch is 0.23 mm. The continuous possible brightness specified by the manufacturer HP is 300 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. HP promises stable color reproduction moreover within a 178 ° vertical angle. The refresh rate is horizontally seen at the Z38c 27 khz to 130 khz. Vertically, however, the image renews at a minimum rate of 24 hz up to 76 hz. The minimum response time of the monitor is ms. The average response time of the monitor is about ms. The display panel is Anti-glare/Matte.

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 SRGB color space is 98 %.

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 HP 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 5000000 : 1 of dynamic contrast ratio for the monitor Z38c 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:

screen design

The monitor has a width of 89.5 cm without its attached stand/stand. The height is dimensioned at about 39.9 cm , while the for the depth of the monitor should be kept free at about 10.4 cm.
The size of the monitor (stand included) is 55.8 x 89.5 x 24.8 cm (HxWxD). The device weighs 13.8 kg with the stand in place. A height-adjustable stand ensures an improved ergonomic posture during use. The monitor can be moved to a maximum height of 12 cm. This value is always measured from the bottom edge of the screen.

Curved

The Z38c is a curved monitor with a curvature of 2.3 m

Rotate, tilt and swivel

The monitor from HP cannot be rotated. The Z38c can be swiveled when mounted on the included stand. Pivoting to the left is possible up to 45 degree. Pivoting to the right is possible up to 45 degree. It is possible to adjust the tilt angle of the monitor Z38c according to personal preference to ensure ergonomic and comfortable viewing. The angle of inclination to the rear is 20. The monitor can be tilted forward by 5 degree.

Ports

camera

This monitor does not have a camera.

Loudspeaker

Features

  • Flicker Free: HP 's Flicker Free technology minimizes distracting screen flicker, allowing you to work and/or play longer without restrictions.
  • The display/monitor supports Frame Rate Compensation.

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 HP 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 LM375QW1-SSA1.

WiFi / Bluetooth

Power consumption

On average, the monitor consumes approximately 80 w. The maximum power consumption (peak) specified for this monitor is 195 w. In standby mode, the device consumes approximately 0.5 w. When switched off, on the other hand, the monitor consumes only 0.5 w. In ECO mode, the monitor consumes 64 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 permissible ambient temperature is 40 °C during operation. Below a temperature of 0 °C , the monitor from HP 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 90 percent. The minimum humidity during storage should not fall below 10 percent. The maximum storage temperature should be according to HP 65 °C. Minimal were given by HP -20 °C.

Packaging

The monitor is packaged in a cardboard box measuring 55.5 x 1.06 x 45.2 cm (height x width x depth). The box together with the monitor weighs about 21 kg.
