LG has unveiled two new monitors in its UltraGear series, which it says are the first 1ms Nano-IPS Nvidia G-Sync monitors in the world. Two models have been launched, the 27-inch 27GL850, with a 144Hz maximum refresh rate, and the 37.5-inch 38GL950G, which has an overclocked maximum refresh rate of 175Hz. LG calls these monitors “a gamer’s dream come true” because of their ability to reproduce 98 percent of the DCI-P3 colour space and 135 percent of the sRGB colour space, as well as their ultra-fast 1ms grey-to-grey response time. The company promises the most immersive gaming experience yet.
Both monitor models support Nvidia’s G-Sync variable refresh rate technology. The 37.5-inch 38GL950G model features a curved screen with a 21:9 aspect ratio and resolution of 3840×1600 (UWQHD+) and 450nits typical brightness. It is compliant with the Vesa DisplayHDR 400 specification. LG boasts of a virtually borderless design and 144Hz refresh rate that can be overclocked to a maximum of 175Hz. An array of RGB LED lights called Sphere Lighting 2.0 on the rear can be set to project colour matching what’s on the screen or in-game sounds, to create an immersive ambience.
The flat 27-inch 27GL850 model supports HDR10 and AMD FreeSync (Vesa Adaptive Sync), and is validated by Nvidia for the G-Sync Compatible specification. It has a resolution of 2560×1440 (QHD), with a typical brightness of 350nits. LG says it is free from flickering and artefacts. It is “virtually borderless” on three sides and its stand allows tilt, swivel, and height adjustment. It can reproduce the same 98 percent DCI-P3 and 135 percent sRGB colour spaces as its bigger sibling. It does not have the Sphere Lighting 2.0 feature.
LG says these are the world’s first 1ms grey-to-grey IPS displays, without sacrificing any performance to achieve this speed. The 38GL950G has one HDMI and one DisplayPort input each, while the 27GL850 has two HDMI ports and one DisplayPort. Both models feature USB 3.0 hubs with two downstream ports.
The larger LG UltraGear 38GL950G is priced at $1,999.99 (approximately Rs. 1,38,840) while the UltraGear 27GL850 monitor is priced at $499.99 (approximately Rs. 34,710). They are being shown off in partnership with Nvidia at the E3 2019 gaming expo in Los Angeles, which runs from June 11 to 13. Pre-orders for the UltraGear 27GL850 will begin on July 1 in the USA, but there is no information yet about the availability of the larger UltraGear 38GL950G.
Bose Frames AR Audio Sunglasses Launched in India, Priced at Rs. 21,900
Over a year after originally showcasing its audio AR sunglasses, Bose is bringing them to the Indian market. The company on Thursday announced that the sunglasses, which are simply known as Bose Frames, will go on sale beginning next week in the country alongside Bose Frames Lens Collection. The Bose Frames combine three functionalities into one device – premium sunglasses, wireless headphones, and audio AR features. The Bose Frames are the company’s first product to be based on the company’s AR platform.
The Bose Frames carry a price tag of Rs. 21,900 and will be offered in two universal styles – the larger Alto and the smaller Rondo. The Bose Frames Lens Collection of non-polarised and polarised lenses will retail at Rs. 1,990 and Rs. 2,990, respectively. The sales open June 20 via select resellers and Bose stores in the country.
The Bose Frames are essentially a pair of sunglasses that pack a tiny Bose audio system in the temples. This audio system effectively turns them into a wireless pair of headphones. The Bose Frames also include a microphone and multi-function button on the right temple for power and pairing, Siri and Google Assistant, calls and commands, or to pause and skip songs.
“With a proprietary open-ear design, they [Bose Frames] take micro-acoustics, voice control, and personal audio to an entirely new level, so users can stream music and information, take and make calls, and access virtual assistants from — while keeping playlists, entertainment, and conversations private,” Bose said in a statement.
Like many wearable devices, the Bose Frames act as a companion device to your smartphone and need the same for processing the information and connecting to the Web.
As we mentioned earlier, the Bose Frames will be released in two designs – Alto and Rondo. Alto is square and angled, whereas Rondo is round and smaller. Both can block up to 99 percent of UVA/UVB rays and weigh just 45 grams. The lenses can be easily popped out and replaced.
Apart from the audio capabilities, the Frames are also compatible with Bose’s AR platform. The Bose Frames don’t include any visual AR capabilities, but they can provide audio AR input to enhance your experience.
“[Bose Frames] knows where you are and what you’re facing using a 9-axis head motion sensor and the GPS from your iOS or Android device — and automatically adds a layer of audio through Bose AR apps, connecting that place and time to endless possibilities for travel, learning, entertainment, gaming, and more,” Bose explained.
Bose AR apps can be downloaded using Bose Connect app and are only available for iOS right now. Android apps are being developed, according to the company’s website.
The company claims that onboard battery can last up to 3.5 hours for playback and up to 12 hours on standby. It can be fully recharged in less than two hours.
Novel device can quickly detect strokes
Scientists have developed a device that can monitor blood flow and help quickly diagnose and treat strokes.
A stroke, one of the leading causes of death worldwide, occurs due to poor blood flow to the brain — a condition known as cerebral ischemia.
Its diagnosis must be done within the first few hours for treatment to be effective, researchers said.
The hybrid device, developed by researchers at the China Academy of Engineering Physics and Army Medical University in China, relies on a combination of to light measuring techniques which could diagnose cerebral ischemia non-invasively and faster than the techniques used currently.
“We can measure blood volume, blood oxygenation and blood flow using suitable near-infrared techniques,” said Liguo Zhu, from China Academy of Engineering Physics.
Zhu said that “near-infrared light penetrates one to three centimetres and allows researchers to probe under the skin.”
The working of the instrument relies on the combination of the near-infrared diffuse optical spectroscopy, which analyses the light scattered from the tissues to calculate the amount of oxygen and blood within an area, and the diffuse correlation spectroscopy, which analyses fluctuation in the tissue-scattered lights to measure blood flow.
“Both techniques share the same detectors, which decreases the number of detectors compared to other instruments,” said Zhu.
“The team’s device can record a comprehensive profile of a body part’s hemodynamics, or blood circulation. Devices should measure as many ‘hemodynamic parameters’ as necessary to obtain an accurate diagnosis, as ‘the hemodynamics of stroke is complex’,” said Hua Feng, from Army Medical University.
Another advantage of the device is that it is cheap and compact, which would make more accessible to the people, and hence, help treatment, diagnosis and chances of stroke, researchers said.
Parineeti ‘still learning’ to play badminton
Actress Parineeti Chopra has not started shooting for ‘Saina’ yet and says she is still learning how to play badminton.
Parineeti on Thursday said that the shooting for the biopic will commence in October.
“Hi everyone, we have not started the shoot of ‘Saina’ yet. I am still learning how to play Badminton! We will start in October once I get better at it! Four months to go,” she tweeted.
Parineeti had replaced actress Shraddha Kapoor in the Saina Nehwal biopic, which is being directed by Amole Gupte.
She will next be seen in ‘Jabariya Jodi’ along with actor Sidharth Malhotra. The film is scheduled for release on August 2. Directed by Prashant Singh, ‘Jabariya Jodi’ is based on ‘Pakadwa Vivah’ (forced marriage), which was once rampant in Bihar.
