8K Ultra HD TV standard

26.09.2019

The TV industry has gone one step further to approve the 8K TV specification, which has not been well defined in recent years and has been interpreted differently on different TVs. From now on, the 8K Ultra HD (UHD) format is officially approved, certified, the exact specification is written for it and the logo is approved.

The Consumer Technology Association has released the official definition of displays for 8K TVs. Any model that complies with the new standard must have a panel with a resolution of at least 7680 x 4320 pixels, support 24, 30 and 60 frames per second, reproduce 10-bit color, support key HDR features, and use HDCP 2.2 level content protection.

The CTA requires Ultra HD TVs to be able to upscale SD, HD, and 4K video to 8K (upscaling). This is to ensure that the video doesn't blur or distort in any way in the absence of native 8K content.

Inclusion in the 8K certification program is completely voluntary. This is somewhat of a formality. Nevertheless, according to the association, manufacturers will certainly want to participate in the adoption of the standard, because there are already televisions of this quality on the market. Manufacturers will be able to apply the new 8K logo on their devices from January 1, 2020.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

Energy from space for Starship 08.05.2024

Producing solar energy in space is becoming more feasible with the advent of new technologies and the development of space programs. The head of the startup Virtus Solis shared his vision of using SpaceX's Starship to create orbital power plants capable of powering the Earth. Startup Virtus Solis has unveiled an ambitious project to create orbital power plants using SpaceX's Starship. This idea could significantly change the field of solar energy production, making it more accessible and cheaper. The core of the startup's plan is to reduce the cost of launching satellites into space using Starship. This technological breakthrough is expected to make solar energy production in space more competitive with traditional energy sources. Virtual Solis plans to build large photovoltaic panels in orbit, using Starship to deliver the necessary equipment. However, one of the key challenges ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

Acer 4K monitor with NVIDIA G-Sync support 18.09.2014

Acer has begun shipping previously announced gaming monitors with support for NVIDIA G-Sync adaptive sync technology.

The XB270H model is not very interesting, although it supports a screen refresh rate of 144 Hz, but the XB280HK, although it has a refresh rate of only 60 Hz, boasts not only G-Sync support, but also a resolution of 3840x2160. The response time is stated at the level of one millisecond.

Among other features of the novelty, it is worth noting an ergonomic stand with wide possibilities for adjusting the height and angle of the screen, which is not so common these days among monitors aimed not at professionals, but at ordinary users. Even the portrait orientation of the panel is supported. For those who play or work in bright light, the Acer XB280HK is built with a ComfyView matte finish.

Bulk deliveries of the XB280HK and XB270H have already begun, monitors can be purchased for $600 for a model with a smaller diagonal and resolution, and $800 will have to be paid for a resolution of 3840x2160 bundled with NVIDIA G-Sync.

This monitor lacks only a higher quality matrix than TN, but then its price would be much higher. To connect to the gaming system, a DisplayPort 1.2 connector is used, but it is now found on any more or less modern graphics card.
