Today we will look at the monitor ThinkVision LT2934z from Lenovo from the year 2013. 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
29 inches ( 73 cm on the diagonal) offer sufficient space for texts in any office applications, for example. As already known, two monitors with different outer dimensions can have the same screen diagonal. In the case of the monitor ThinkVision LT2934z , we find an aspect ratio of 2.37 to 1. This means that for every 1 pixels in height, 2.37 pixels in width are added. For comparison: A classic CRT monitor had an aspect ratio of 4:3. The display is a AH panel. The panel has a resolution of 2560 x 1080 px. The pixel density is 96 ppi. The pixel pitch is 0.263 mm. The continuous possible brightness specified by the manufacturer Lenovo 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. Lenovo promises stable color reproduction moreover within a 178 ° vertical angle. The refresh rate is horizontally seen at the ThinkVision LT2934z 30 khz to 83 khz. Vertically, however, the image renews at a minimum rate of 30 hz up to 75 hz. The minimum response time of the monitor is ms. The maximum 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 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 70 % according to the manufacturer. 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 100 %.
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 Lenovo 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 3000000 : 1 of dynamic contrast ratio for the monitor ThinkVision LT2934z 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
If you want to place the monitor described here on the desk without a wall mount, you should allow for 38 x 69.9 x 23.9 cm (HxWxD) of space. A height-adjustable stand ensures an improved ergonomic posture during use. The monitor can be moved to a maximum height of 11 cm. This value is always measured from the bottom edge of the screen.
Rotate, tilt and swivel
The monitor from Lenovo cannot be rotated. The ThinkVision LT2934z 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. The monitor ThinkVision LT2934z can be tilted. The angle of inclination to the rear is 25. The monitor can be tilted forward by 5 degree.
Ports
The monitor can be connected via 1 VGA ports.
camera
The monitor has a built-in camera. The built-in camera has a maximum resolution of 1920 x 1080 px when recording video with the camera.
Loudspeaker
The monitor from Lenovo 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 3 w power.
Features
- Flicker Free: Lenovo '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
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 Lenovo 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 LM290WW1-SSA1.
WiFi / Bluetooth
Power consumption
On average, the monitor consumes approximately 50 w. The maximum power consumption (peak) specified for this monitor is 100 w. In standby mode, the device consumes approximately 1.2 w. When switched off, on the other hand, the monitor consumes only 0.5 w. ThinkVision LT2934z 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 45 w. The monitor can be operated on a 110v power supply. The monitor can be operated on a 220v power supply. There are 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 5 km. For temperature, the maximum permissible ambient temperature is 45 °C. Below a temperature of 0 °C , the monitor from Lenovo 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 Lenovo 60 °C. Minimal were given by Lenovo -20 °C. According to the manufacturer, the monitor may be stored at a maximum height of 12.192 km.
