Today we will look at the monitor S2740L from Dell from the year 2012. 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
Games, texts, videos and/or other applications can be displayed on the monitor's 27 inches ( 68.5 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 S2740L from Dell faces 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 82.3 % 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 1920 x 1080 px. The pixel density is 81 ppi. The pixel pitch is 0.311 mm. The continuous possible brightness specified by the manufacturer Dell is 270 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. Dell promises stable color reproduction moreover within a 178 ° vertical angle. The refresh rate is horizontally seen at the S2740L 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. The display panel is Anti-glare/Matte (3H).
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 NTSC 1953 color space is 72 %. According to the manufacturer, the coverage of the SRGB color space is 84 %.
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 Dell 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 8000000 : 1 of dynamic contrast ratio for the monitor S2740L 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 following dimensions must be planned for a free-standing stand without attached feet/stand: 38 cm x 64.1 cm x 6.1 cm (HxWxD)
The size of the S2740L on the desk is likely to be particularly relevant for most users. Dell specifies a space requirement of 45.8 x 64.1 x 21.5 cm (HxWxD) with the included stand. The device weighs in total (i.e. also measured with the stand) 7.56 kg. The monitor S2740L without the stand weighs 5.28 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.
Rotate, tilt and swivel
The monitor from Dell cannot be rotated. The monitor cannot be swiveled. This feature could be retrofitted with a third-party stand. Thanks to the tilt function of the S2740L monitor, the screen position can be flexibly adjusted to minimize dazzling light sources and ensure optimum visibility. The angle of inclination to the rear is 21. The monitor can be tilted forward by 4 degree.
Ports
The monitor can be connected via 1 VGA ports. There are 1 HDMI ports on the monitor.
camera
This monitor does not have a camera.
Loudspeaker
Features
- 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 Dell 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 LM270WF5-SLB1.
WiFi / Bluetooth
Power consumption
The average consumption figure for S2740L is 21 w. The maximum power consumption (peak) specified for this monitor is 35 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 11 w. The monitor can be operated on a 110v power supply. The monitor can be operated on a 220v power supply. There are 1.2 amps specified. 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 3.048 km. The maximum permissible ambient temperature is 40 °C during operation. Below a temperature of 0 °C , the monitor from Dell 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 90 percent. The minimum humidity during storage should not fall below 5 percent. The maximum storage temperature should be according to Dell 60 °C. Minimal were given by Dell -20 °C. According to the manufacturer, the monitor may be stored at a maximum height of 10.668 km.
