Vizio M-Series Quantum 4K UHD TV review: Same accurate color, now with upgraded ports

PCWorld

It didn't take long to confirm what I suspected during my Vizio V5-Series review--the slightly more expensive M-Series Quantum offers a far better picture. It's not perfect perfect by any means, but the color is more accurate, and the screen uniformity far outstrips that of the V-Series. If you're shopping mid-range Vizio, the M-Series Quantum is what you want. Skip a couple of lunches to save up the extra cash. The M-Series, including the 55-inch class model M55Q6 that I tested, are 60Hz, 3840 x 2160 (4K UHD), 10-bit TVs.


Hisense U8G-series 4K UHD TV review: Nice for the price, especially for gamers

PCWorld

It's a very nice set, although we missed the deep black performance we've seen in some competitors outfitted with mini-LED backlights. The U8G-series is available in both 55-inch ($950) and 65-inch ($1,300, reviewed here) sizes. It uses a 120Hz, 10-bit, 4K UHD (3840 x 2160) panel featuring quantum dots for extremely accurate color. The TV is a bit on the heavy side, weighing close to 53.4 pounds on the wall (with VESA 400 mm x 400 mm mount), and 56 pounds including the stand. The bezel is thin, and there's a classy look to the whole deal.


Samsung QN90A 55-inch 4K UHD TV review: Mini-LED meets quantum dots

PCWorld

Samsung's Neo QLED QN90A takes the company's already outstanding QLED color and brightness and, thanks to far more granular mini-LED backlighting, enhances it with far better blacks. The overall result is truly impressive, although Samsung still has some work to do on its zone dimming techniques. The 54.6-inch (55-inch class) version of the QN90A I tested currently retails for around $1,700 and features a 4K UHD (3840 x 2160), 120Hz, 10-bit display. Said display implements quantum dots for accurate, saturated color, and mini-LEDs for refined backlighting. Mini-LEDs, as you might guess, are far smaller than traditional backlight LEDs.


I've fallen in love with this Asus miniLED 4K panel

PCWorld

If you're the kind of person who puts doing work ahead of playing games, you'll understand why I think the Asus ROG Swift PG32UQX might be the perfect monitor. Announced April 29 and due to ship by the end of May, the ROG Swift PG32UQX is a feature-packed panel possessing just about every acronym you can find, including: miniLED, DisplayHDR 1400, IPS, 10-bit, G-Sync Ultimate, 144Hz, and 4K. That's probably just alphabet soup to regular people, so let me translate it for someone who works more than they game--but is tired of staring at compromise every day in the form of some random 1080p LCD. The top feature of the ROG Swift PG32UQX is its use of miniLEDs. These smaller, highly efficient light sources are still rare in PCs--we just saw the MSI Creator 17, the first laptop with a miniLED display.


RL-IoT: Towards IoT Interoperability via Reinforcement Learning

arXiv.org Artificial Intelligence

Our life is getting filled by Internet of Things (IoT) devices. These devices often rely on closed or poorly documented protocols, with unknown formats and semantics. Learning how to interact with such devices in an autonomous manner is key for interoperability and automatic verification of their capabilities. In this paper, we propose RL-IoT -- a system that explores how to automatically interact with possibly unknown IoT devices. We leverage reinforcement learning (RL) to understand the semantics of protocol messages and to control the device to reach a given goal, while minimizing the number of interactions. We assume only to know a database of possible IoT protocol messages, whose semantics are however unknown. RL-IoT exchanges messages with the target IoT device, learning those commands that are useful to reach the given goal. Our results show that RL-IoT is able to solve simple and complex tasks. With properly tuned parameters, RL-IoT learns how to perform actions with the target device, a Yeelight smart bulb for our case study, completing non-trivial patterns with as few as 400 interactions. RL-IoT opens the opportunity to use RL to automatically explore how to interact with IoT protocols with limited information, and paving the road for interoperable systems.


Bulbrite Solana Smart LED Filaments Tunable White A19 review: Inexpensive and intuitive, but feature-deprived

PCWorld

If you're looking for an attractive, easy-to-use smart filament bulb that won't break the bank, this inexpensive model from Bulbrite's Solana line makes for a solid choice. Available for $20, The Smart LED Filaments Tunable White A19 is a Wi-Fi-enabled bulb that doesn't require a hub, and unlike other smart filament bulbs in its price range, you can tune it from a warm white to a cool daylight temperature. Easy wireless setup and a sleek, intuitive app should please newcomers to the smart home market. Some key features are missing, however, such as proper sleep/wake modes as well as a vacation mode. And while the Bulbrite Solana bulb does support Alexa and Google Assistant, it lacks support for Apple's HomeKit and IFTTT.


Artificial Intelligence Revolutionizing the Smartphone Industry

#artificialintelligence

Artificial intelligence (AI) is on the verge to unleash its potential impact in the smartphone industry. Isn't it amazing to find how smartphones when integrated with AI have the capability of making their own choices as per the environment? Smartphones have become smarter than ever before, and with AI on the rise, the features could be limitless. However, with AI integration, your smartphone will only get better. From offering better protection to providing lower latency and efficiency improvement, your phone can make its choice without having the need to configure them.

Sylvania A19 Smart Full Color review: This sensible no-hub bulb works with Alexa and Google Assistant

PCWorld

If you're looking for an affordable color smart bulb that works with both Amazon Alexa and Google Assistant, the Sylvania A19 Smart Full Color bulb is a fine candidate, although you can't buy just one. This standard A19 bulb connects directly to Wi-Fi networks, meaning there's no need for a bridge or smart-home hub. Sylvania's mobile app offers a variety of grouping options, lighting scenes, and powerful automation tools. That said, we still prefer the more polished apps that come bundled with our favorite A19 smart bulbs from LIFX and Philips Hue. The Sylvania bulb also lacks the HomeKit support that LIFX and Hue bulbs deliver, but that will matter only to Apple users who use that ecosystem.


The Best Smart Bulbs for Apple HomeKit

USATODAY - Tech Top Stories

Across the board, Philips Hue LED lights topped all of our tests thanks to an easy setup, a robust suite of features, and an intuitive app. Additional support with smart assistants like Alexa, Google Assistant, and Siri adds tremendous benefit to an already impressive portfolio. Once you throw in the additional rainbow of possible light colors, these are without a doubt the best smart bulbs you can buy. The only downside is that unlike some other options, Philips Hue lights do require a hub (the Philips Hue Bridge) in order to work remotely. While they can be controlled over Bluetooth, that will only work when you're physically near the bulb.
