I have two of those. Our house has two Xbox Series X, after all. :lol:

The graphics are superb, indeed. You just have to adjust the display settings depending on which game you are playing, though.
To know is essentially the same as not knowing. The only thing that occurs is the rearrangement of atoms in your brain.

4K Laser TV uses liquid cooling for super-quiet operation
By Paul Ridden

The GAC Technology Group partnered with HP Inc in early 2017 for a 10-year alliance to develop and market smart projectors. The BP5000 is the latest fruit of that collaboration, a Laser TV 4K ultra-short-throw projector that has won't disturb movie watchers with irritating fan noise.

Currently funding on Indiegogo, the HP BP5000 DLP projector uses an ALPD 3.0 fluorescence laser light source for more than 25,000 hours of use, and features liquid cooling to keep the system from running hot, so users should benefit from very quiet operation.

New synthesis process paves way for more efficient lasers, LEDs
https://phys.org/news/2021-10-synthesis ... asers.html
by Matt Shipman, North Carolina State University
Researchers from North Carolina State University have developed a new process that makes use of existing industry standard techniques for making III-nitride semiconductor materials, but results in layered materials that will make LEDs and lasers more efficient.

III-nitride semiconductor materials are wide-bandgap semiconductors that are of particular interest in optic and photonic applications because they can be used to create lasers and LEDs that produce light in the visible bandwidth range. And when it comes to large-scale manufacturing, III-nitride semiconductor materials produced using a technique called metal organic chemical vapor deposition (MOCVD).

Semiconductor devices require two materials, a "p-type" and an "n-type." Electrons move from the n-type material to the p-type material. This is made possible by creating a p-type material that has "holes," or spaces that electrons can move into.

A challenge for people who make LEDs and lasers has been that there was a limit on the number of holes that you can make in p-type III-nitride semiconductor materials that are created using MOCVD. But that limit just went up.

"We have developed a process that produces the highest concentration of holes in p-type material in any III-Nitride semiconductor made using MOCVD," says Salah Bedair, co-author of a paper on the work and a distinguished professor of electrical and computer engineering at NC State. "And this is high quality material – very few defects – making it suitable for use in a variety of devices."

Unlocking the technology to produce unbreakable screens
https://phys.org/news/2021-10-technolog ... reens.html
by University of Queensland
Cracked phone screens could become a thing of the past thanks to breakthrough research conducted at The University of Queensland.

The global team of researchers, led by UQ's Dr. Jingwei Hou, Professor Lianzhou Wang and Professor Vicki Chen, have unlocked the technology to produce next-generation composite glass for lighting LEDs and smartphone, television and computer screens.

The findings will enable the manufacture of glass screens that are not only unbreakable but also deliver crystal clear image quality.

Dr. Hou said the discovery was a huge step forward in perovskite nanocrystal technology as previously, researchers were only able to produce this technology in the bone-dry atmosphere of a laboratory setting.

"The emitting materials are made from nanocrystals, called lead-halide perovskites," he said.

Researchers set their sights on chalcogenide nanostructured displays
https://phys.org/news/2022-01-sights-ch ... tured.html
by Singapore University of Technology and Design
One of the key components behind next-generation high resolution video displays will be optical nanoantennas. These devices use nanotechnology to mix and interfere with light beams to produce color and even holograms.

While optical nanoantennas using silicon or similar materials have produced color images, the images are fixed and cannot be tuned back and forth. However, new materials with tuneable properties are required to exploit optical nanoantennas in high resolution videos.

To address this gap, research teams from Singapore University of Technology and Design (SUTD) and A*STAR IMRE designed and demonstrated the use of chalcogenide nanostructures to reversibly tune Mie resonances in the visible spectrum. With its width measuring at just 190nm—1000 times smaller than a single strand of human hair—the chalcogenide nanodisc can be switched between two optical states using heat to induce phase transitions.

Their work, "Reversible Tuning of Mie Resonances in the Visible Spectrum," was published in ACS Nano.

A year after it started pushing its own TVs, Amazon is expanding its lineup with pricier, more advanced options. The Fire TV Omni QLED Series announced yesterday at the invite-only Amazon hardware event shows the tech giant upping the ante with quantum dot displays and more evolved features for smart homes.

Amazon's first self-branded TVs came last September, ranging from the more budget-friendly 4-Series, which originally started at $370 for 43 inches, and the Omni Series, which originally cost $1,100 for the largest model, at 75 inches. The 4K TVs aren't particularly unique. They're HDR TVs and include HDMI 2.1, with eARC for soundbars, and feature variable refresh rates from a mere 48–60 Hz at 4K. Amazon Alexa is also present, of course. Alexa can work when the TVs are off, enable voice control, and work with Alexa Routines but is not an Amazon-exclusive among modern TVs.

Amazon is paying a little more attention to image quality with the Omni QLED Series; it still avoids specific claims, though, like brightness or color coverage specs. The new 65- and 75-inch TVs use Samsung Display's QLED technology with quantum dots for a claimed boost in color, plus full-array local dimming to boost contrast.

We won't know how well local dimming on the Omni QLED TVs work until we see them in person, but they at least include enough dimming zones to be compared against TV's biggest players, like Samsung. Samsung's 2022 65-inch QLED TV, the Q80B, has 48 dimming zones, according to reviewer Rtings, while carrying a higher MSRP ($1,200).
And remember my friend, future events such as these will affect you in the future

First truly wireless TV sticks to walls, has zero ports and no remote
By Scott Tharler
January 16, 2023
https://newatlas.com/home-entertainment ... no-remote/
At CES 2023, Displace showed how its futuristic, battery-powered 55-inch 4K TV utilizes a special pop-up camera to recognize gesture controls and a proprietary active-loop vacuum seal to adhere itself to walls.

The gesture controls of the DisplaceTV that most caught our eye at the show were the ability to use your finger as a mouse to select particular on-screen channels/options, plus a fancy two-handed flourish to enlarge what’s on one screen to fill all four. By the way, such a configuration – a two-by-two grid of DisplaceTVs – would essentially create an 8K 110-inch TV capable of streaming four different channels at once. Or if you position them on different walls with their respective cameras popped up, you can enable your content to seamlessly follow you around the house.

Apple TV 4K will support FaceTime calls using your iPhone's camera

https://www.gsmarena.com/apple_tv_now_s ... -58784.php
Today at its annual developer conference, Apple announced updates for all its various operating systems, and tvOS is one of them. With the upcoming tvOS 17, due to release sometime this fall, the Apple TV 4K is getting support for FaceTime.

The new FaceTime app for tvOS will let you initiate calls directly from your Apple TV, or start calls on your iPhone or iPad and then hand them off to the Apple TV. FaceTime on Apple TV takes advantage of Apple's Continuity Camera feature to wirelessly connect to your iPhone or iPad in order to use its camera and microphone to record your side of the call, while the people you're talking to will be shown on the TV.

Compact Atom laser projector puts Google TV in sharp focus
By Paul Ridden
February 19, 2024
https://newatlas.com/home-entertainment ... google-tv/
One of China's top consumer tech brands, Dangbei, launched a mini-PC-sized Full HD laser projector at IFA 2023 in Germany last year that was its first to run Google TV. The Atom made its way to the US for CES recently, and we've been sent one for review.

Dangbei was founded in 2013 as a TV network platform, and began making and selling smart projectors in 2019. The company is now reported to sit at the top of the laser projector tree in China. The Atom is its thinnest projector so far, at just 1.87 in (4.75 cm), and has the outward look of a mini desktop computer.

This means that it can be slipped into a backpack for easy transport to a friend's house (it tips the scales at 2.82 lb/1.28 kg), but the unit lacks an internal battery and the power brick is a bit of a monster, so you'd need to factor in the adapter's 5.7 x 2.5 x 1.18 in (14.5 x 6.35 x 2.9 cm) dimensions and 30 oz (850 g) weight – plus the cable and wall outlet needs – before going mobile with this setup.
