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 C34J791 from Samsung.
Display
Let's start with the most important component of a monitor, the display. Depending on the aspect ratio of height and width, monitors can be rather wide or square, for example. Besides the pure physical dimensions, the resolution of the display and thus the quality of the display is also decisive here. For easy comparability, however, screen sizes are usually given in inches. This unit of measurement simply compares the diagonal length from the lower left to the upper right corner of the display and is thus universally applicable. This device has a screen diagonal of 34 inches ( 86.3 cm on the diagonal). 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 C34J791 from Samsung faces an aspect ratio of 2.389 : 1. 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 91.2 % 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 SVA panel. The panel has a resolution of 3440 x 1440 px. The pixel density is 109 ppi. The pixel pitch is 0.233 mm. The continuous possible brightness specified by the manufacturer Samsung is 300 nt. The panel is illuminated by Edge 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. Samsung promises stable color reproduction moreover within a 178 ° vertical angle. The refresh rate is horizontally seen at the C34J791 30 khz to 152 khz. Vertically, however, the image renews at a minimum rate of 48 hz up to 100 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 (2H).
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. The coverage of the Adobe RGB 1998 color space is 92 % according to the manufacturer. According to the manufacturer, the coverage of the SRGB color space is 125 %.
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 Samsung has a static contrast ratio of 3000 : 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 100000000 : 1 of dynamic contrast ratio for the monitor C34J791 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
For a possible wall mounting or comparison to the currently owned monitor at the beginning, the dimensions of the monitor without stand/feet: 36.2 cm x 80.8 cm x 16.7 cm (HxWxD)
The size of the monitor (stand included) is 51.6 x 80.8 x 30.9 cm (HxWxD). The device weighs 7.7 kg with the stand in place. Without stand, the monitor weighs 6.3 kg. 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 10 cm. This value is always measured from the bottom edge of the screen.
Curved
The C34J791 is a curved monitor with a curvature of 1.5 m
Rotate, tilt and swivel
The monitor from Samsung cannot be rotated. The monitor cannot be swiveled. This feature could be retrofitted with a third-party stand. The monitor C34J791 can be tilted. The angle of inclination to the rear is 34. The monitor can be tilted forward by 2 degree.
Ports
camera
This monitor does not have a camera.
Loudspeaker
The monitor from Samsung 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 7 w power.
Features
- Flicker Free: Samsung 's Flicker Free technology minimizes distracting screen flicker, allowing you to work and/or play longer without restrictions.
- AMD FreeSync: By dynamically synchronizing the refresh rate of the C34J791 with the frame rate, AMD FreeSync minimizes judder and ensures smooth and enjoyable gameplay.
- Picture by Picture mode
- Picture in Picture mode
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 Samsung offers a technology to reduce the blue content in its monitor C34J791.
WiFi / Bluetooth
Power consumption
The average consumption was given by Samsung as 180 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. C34J791 supports a static ECO mode, which for example lowers the refresh rate, reduces brightness and disables AI functions to save energy. In ECO mode, the monitor consumes 65 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 10 °C , the monitor from Samsung should again not be used. The humidity must not exceed 80 percent. At least, however, 10 percent humidity. The monitor may be stored at a maximum humidity of 95 percent. The minimum humidity during storage should not fall below 5 percent. The maximum storage temperature should be according to Samsung 60 °C. Minimal were given by Samsung -20 °C.
