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 U4309V from AOC.
Display
The monitor belongs to the device class 43 inches ( 1.08 m on the diagonal). As already known, two monitors with different outer dimensions can have the same screen diagonal. In the case of the monitor U4309V , we find an aspect ratio of 1.778 to 1. This means that for every 1 pixels in height, 1.778 pixels in width are added. For comparison: A classic CRT monitor had an aspect ratio of 4:3. 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 89.8 % 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 VA 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 AOC is 450 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. AOC promises stable color reproduction moreover within a 178 ° vertical angle. The refresh rate is horizontally seen at the U4309V 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.
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 DCI-P3 color space is 98 %. According to the manufacturer, the coverage of the NTSC 1953 color space is 108 %. According to the manufacturer, the coverage of the SRGB color space is 129 %.
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 AOC has a static contrast ratio of 4000 : 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 20000000 : 1 of dynamic contrast ratio for the monitor U4309V cannot provide any information about the severity of the halo effect here. Therefore, it is more useful to compare the static contrast ratio. The monitor from AOC supports adaptive contrast management, dynamically adjusting the contrast ratio of the input signal to ensure razor-sharp image displays. Each scene is continuously analyzed by U4309V and the images are adjusted accordingly frame by frame. This analysis and dynamic adjustment of contrast is designed to enhance color quality and provide better black levels when displaying dark scenes and shaded/dark image sequences.
HDR
The monitor supports all HDR modes listed here:
- HDR 400
screen design
The following dimensions must be planned for a free-standing stand without attached feet/stand: 56.7 cm x 97.7 cm x 5.8 cm (HxWxD)
If you want to place the monitor described here on the desk without a wall mount, you should allow for 66.4 x 97.7 x 31.1 cm (HxWxD) of space. The base itself has a depth of 31.1 cm. As for the weight, AOC states a total weight of 14.52 kg with stand. Without stand, the monitor weighs 12.69 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 AOC cannot be rotated. The monitor cannot be swiveled. This feature could be retrofitted with a third-party stand. The monitor U4309V offers the option of adjusting the tilt as required to create an ergonomic working environment and reduce visual fatigue. The angle of inclination to the rear is 10. The monitor can be tilted forward by 5 degree.
Ports
camera
This monitor does not have a camera.
Loudspeaker
The monitor from AOC 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: AOC '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
- 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 AOC offers a technology to reduce the blue content in its monitor U4309V.
WiFi / Bluetooth
Power consumption
The average consumption was given by AOC as 94 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. The monitor can be operated on a 110v power supply. The monitor can be operated on a 220v power supply. There are 2.5 amps specified. The power grid has to supply a frequency of 50 hz to 60 hz.
Environment
Packaging
The monitor is packaged in a cardboard box measuring 78.2 x 1.13 x 27.2 cm (height x width x depth). The box together with the monitor weighs about 19.7 kg.
