If you remember back to January of this year, Allyn and posted an article that confirmed the existence of a mobile variant of G-Sync thanks to a leaked driver and an ASUS G751 notebook. Rumors and speculation floated around the Internet ether for a few days but we eventually got official word from NVIDIA that G-Sync for notebooks was a real thing and that it would launch "soon." Well we have that day here finally with the beginning of Computex.
G-Sync for notebooks has no clever branding, no "G-Sync Mobile" or anything like that, so discussing it will be a bit more difficult since the technologies are different. Going forward NVIDIA claims that any gaming notebook using NVIDIA GeForce GPUs will be a G-Sync notebook and will support all of the goodness that variable refresh rate gaming provides. This is fantastic news as notebook gaming is often at lower frame rates than you would find on a desktop PC because of lower powered hardware yet comparable (1080p, 1440p) resolution displays.
Of course, as we discovered in our first look at G-Sync for notebooks back in January, the much debated G-Sync module is not required and will not be present on notebooks featuring the variable refresh technology. So what gives? We went over some of this before, but it deserves to be detailed again.
NVIDIA uses the diagram above to demonstrate the complication of the previous headaches presented by the monitor and GPU communication path before G-Sync was released. You had three different components: the GPU, the monitor scalar and the monitor panel that all needed to work together if VRR was going to become a high quality addition to the game ecosystem.
NVIDIA's answer was to take over all aspects of the pathway for pixels from the GPU to the eyeball, creating the G-Sync module and helping OEMs to hand pick the best panels that would work with VRR technology. This helped NVIDIA make sure it could do things to improve the user experience such as implementing an algorithmic low-frame-rate, frame-doubling capability to maintain smooth and tear-free gaming at frame rates under the panels physical limitations. It also allows them to tune the G-Sync module to the specific panel to help with ghosting and implemention variable overdrive logic.
All of this is required because of the incredible amount of variability in the monitor and panel markets today.
But with notebooks, NVIDIA argues, there is no variability at all to deal with. The notebook OEM gets to handpick the panel and the GPU directly interfaces with the screen instead of passing through a scalar chip. (Note that some desktop monitors like the ever popular Dell 3007WFP did this as well.) There is no other piece of logic in the way attempting to enforce a fixed refresh rate. Because of that direct connection, the GPU is able to control the data passing between it and the display without any other logic working in the middle. This makes implementing VRR technology much more simple and helps with quality control because NVIDIA can validate the panels with the OEMs.
As I mentioned above, going forward, all new notebooks using GTX graphics will be G-Sync notebooks and that should solidify NVIDIA's dominance in the mobile gaming market. NVIDIA will be picking the panels, and tuning the driver for them specifically, to implement anti-ghosting technology (like what exists on the G-Sync module today) and low frame rate doubling. NVIDIA also claims that the world's first 75 Hz notebook panels will ship with GeForce GTX and will be G-Sync enabled this summer - something I am definitely looking forward to trying out myself.
Though it wasn't mentioned, I am hopeful that NVIDIA will continue to allow users the ability to disable V-Sync at frame rates above the maximum refresh of these notebook panels. With most of them limited to 60 Hz (but this applies to 75 Hz as well) the most demanding gamers are going to want that same promise of minimal latency.
At Computex we'll see a handful of models announced with G-Sync up and running. It should be no surprise of course to see the ASUS G751 with the GeForce GTX 980M GPU on this list as it was the model we used in our leaked driver testing back in January. MSI will also launch the GT72 G with a 1080p G-Sync ready display and GTX 980M/970M GPU option. Gigabyte will have a pair of notebooks: the Aorus X7 Pro-SYNC with GTX 970M SLI and a 1080p screen as well as the Aorus X5 with a pair of GTX 965M in SLI and a 3K resolution (2560x1440) screen.
This move is great for gamers and I am eager to see what the resulting experience is for users that pick up these machines. I have long been known as a proponent of variable refresh displays and getting access to that technology on your notebook is a victory for NVIDIA's team.

I'll be honest with you: I did not see a whole lot that interested me out of the Google I/O keynote. The company released a developer preview of their upcoming Android OS “M”, which refers to the thirteenth alphabetical release (although only eleven were formally lettered because they started with “C”upcake). Version nomenclature aside, this release is supposed to tune the experience. While the platform could benefit from a tune-up, it is also synonymous with not introducing major features.
But some things are being added, including “Google Now on Tap”. The idea is that Google will understand what is happening on screen and allow the user to access more information about it. In a demo on Engadget, the user was looking at scores for the Golden State Warriors. She asked “When are they playing next”, actually using the pronoun “they”, and the phone brought up their next game (it was against the Cavaliers).
Fingerprint reading and Android Pay are also being added to this release.
Other than that, it is mostly performance and usability. One example is “Doze State”, which allows the OS to update less frequently when the device is inactive. It is supposed to play nice with alarms and notifications though, which is good. Normally, I would wait to see if it actually works before commenting on it, but this seems like something that would only be a problem if no-one thought of it. Someone clearly did, because they apparently mentioned it at the event.
Android M, whatever it will actually be called, is expected to ship to consumers in the Fall.
Announced just this past June at last year’s Google I/O event, Android TV is a platform developed by Google, running Android 5.0 and higher, that aims to create an interactive experience for the TV. This platform can be built into a TV directly as well as into set-top style boxes, like the NVIDIA SHIELD we are looking at today. The idea is to bring the breadth of apps and content to the TV through the Android operating system in a way that is both convenient and intuitive.
NVIDIA announced SHIELD back in March at GDC as the first product to use the company’s latest Tegra processor, the X1. This SoC combines an 8-core big.LITTLE ARM processor design with a 256-core implementation of the NVIDIA Maxwell GPU architecture, providing GPU performance previously unseen in an Android device. I have already spent some time with the NVIDIA SHIELD at various events and the promise was clearly there to make it a leading option for Android TV adoption, but obviously there were questions to be answered.
Today’s article will focus on my early impressions with the NVIDIA SHIELD, having used it both in the office and at home for a handful of days. As you’ll see during the discussion there are still some things to be ironed out, some functionality that needs to be added before SHIELD and Android TV can really be called a must-buy product. But I do think it will get there.
And though this review will focus on the NVIDIA SHIELD, it’s impossible not to marry the success of SHIELD with the success of Google’s Android TV. The dominant use case for SHIELD is as a media playback device, with the gaming functionality as a really cool side project for enthusiasts and gamers looking for another outlet. For SHIELD to succeed, Google needs to prove that Android TV can improve over other integrated smart TV platforms as well as other set-top box platforms like Boxee, Roku and even the upcoming Apple TV refresh.
But first, let’s get an overview of the NVIDIA SHIELD device, pricing and specifications, before diving into my experiences with the platform as a whole.

Shortly after the keynote at Lenovo Tech World today,we got hands on with the Dual-Screen Smartwatch concept, the Magic View.
The Magic View is an Android Wear device, which integrates a unique “virtual interactive display" via a small prism on the watch band. Users must bring the device up to their face and look through the prism to see a secondary display for tasks such as video viewing.
Looking inside the Magic View reminded us a lot of Google Glass. As you put your eye up to the prism on the watch band, you could see what looked like a display off in the distance. It was difficult to determine the relative size, but Lenovo claims this display is 20x bigger than the display on the smartwatch itself. Resolution was also undetermined, but it seemed to be low and about on par with the original Google Glass units.
The device itself was a bit warm and the additional display unit added some bulk, but these weren't immediate deal breakers. The design was still ergonomic and seemed like something that you wouldn't have an issue wearing all-day long.
This is definitely an early concept, but the fact that Lenovo are showing off demo units here means that they are serious about the ideas presented in the Magic View. If additional development can solve some of the heat issues, it seems like this would be a feature that doesn't detract from the core use of the device and can provide a potentially value new interaction method.

Today at the Lenovo Tech World keynote presentation, Lenovo CTO Peter Hortensius took the opportunity to show some of the far reaching concepts for smartphones and smartwatches.
The Magic View smartwatch is a stylish, round smartwatch reminiscent of the Moto 360 that seems from the concept renderings to be based around Android Wear. However, the uniqueness comes from what Lenovo is claiming makes it the only smartwatch with two screens.
Optical reflection is used inside of a portion of the strap in order to project a second “virtual interactive display” more than 20 times larger than the integrated display. This is made possible through Lenovo-designed silicon aimed at miniaturizing the components for this type of projection while maintaining the same performance.
Lenovo claims this secondary screen will be useful for things like maps, as well as photo and video viewing, but it be remains to be seen if users would favor a virtual display like this over simply using their existing smartphone display. Privacy is also a big part of what Lenovo is pitching with the Magic View. Since users must place the lens portion next to their eye, other people in the same area cannot look over their shoulders and view potientially sensitive information.
The Lenovo Smart Cast concept plays on a similar idea as the Magic View. Through the use of a build in laser projector, as well as specialized sensors, Lenovo aims at allowing users to project a large virtual touch screen onto tabletop surfaces.
With the use of infrared sensors, users can touch the surface underneath the projection and interact just as if it were a physical display. Lenovo points towards this being useful for such applications as virtual keyboards in productivity apps, or even for media control of projected movies and light gaming such as Fruit Ninja.
The projected display is also independent of the smartphone display, allowing things such as two separate views for video chatting applications.
It remains to be seen if these concepts will ever actually make it into production devices, and if those devices will ever hit North America, but it's always interesting to see what R&D divisions of large companies like Lenovo are up to.

Today at their Tech World event in Beijing, Lenovo is taking the opportunity to announce some new mainstream notebook options.
First off, we have simply the Lenovo Z41 and Z51. The 14-inch Z41 and 15.6-inch Z51 aim to refresh the previous Z40 and Z50 with Broadwell CPUs as well as new AMD discrete GPU options.
Lenovo is using the Broadwell-U class of CPUs here as you would find in ultra books, so don't expect a CPU powerhouse, but for productivity style tasks these machines should hit the sweet spot of Price vs Performance with a starting price of $549 for the base Z51.
Paired with the new AMD R9-M360 (Z41) or M375 (Z51) these notebooks should also be able to play mainstream titles on the integrated 1080p display while coming in just over $800.
Lenovo also announced a low-cost entry into the ideapad line utilizing Intel's BayTrail-M processors. The ideapad 100 is available in both 14-inch and 15-inch variants and seems to be aimed at the low-cost Chromebook market.
Starting at $249, the ideapad 100 seems like it will be a good option for users looking for a secondary option for basic web browsing and office tasks.
Stay tuned for more from Lenovo's Tech World Event this week!
Introduction: Improving Portable Sound
The Calyx PaT is very small USB DAC and headphone amp that can be used with PCs and mobile devices, offering the possibility of better sound from just about any digital source. So how does it sound? Let’s find out!
The PaT is a very interesting little device, to be sure. It rather resembles a large domino and weighs less than 1 ounce thanks to an ultra-light aluminum construction. It requires no battery or power source other than its micro USB connection, yet it provides sufficient power (0.8 V output) for in-ear monitors and efficient headphones through its 3.5mm headphone jack. Inside is a proprietary mix of DAC and amplifier circuitry, and like other products produced by Calyx, a Korean company with little presence in the United States, there is the promise of a dedication to great sound. Did Calyx pull it off with the diminutive PaT?
Improving Portable Sound
Outboard DACs and headphone amplifiers for computers and mobile devices are nothing new, with recent products like AudioQuest’s Dragonfly a prime example in the portable USB DAC market (though it offers no mobile support). When I first heard about the PaT during CES it was still in the prototype stage, but I was interested because of the Calyx name if nothing else, as I already owned the Calyx M DAP and had been quite honestly blown away by the sound.
So what need might I have for the interestingly-named PaT (pronounced "paat", meaning "bean" in reference to the small size), which is itself a DAC that requires another device to play music files? It wasn’t until I had the opportunity to speak with Calyx president Seungmok Yi during CES (via video chat as I couldn’t attend the show) that I started realize that this could be a compelling product, not just for the $99 price tag - a bargain for an audiophile product - but because of how versatile the PaT can be. You don't have to identify as an "audiophile" to appreciate the clearer and more detailed sound of a good DAC, especially when so many of us simply haven't heard one (especially on mobile devices).

Tagged: asus, transformer book, T300 Chi
The ASUS Transformer Book T300 Chi comes in a number of models, with the base mode running just under $700. The Tech Report had a chance to review the higher end model which is more expensive and harder to find. This particular model sports a 2.9GHz Broadwell based Core M 5Y71, 8GB DDR3-1600 and an internal 128GB internal SanDisk iSSD. The 12.5" IPS 2560x1440 screen is common to all models, as is WiFi connectivity and Windows 8.1, 64-bit. The keyboard portion of this Transformer Book is more of a screen stand than a dock as it uses Bluetooth to connect to the tablet as opposed to a physical interface, magnets keep the tablet in place when you are docked. Check out how well it performs in The Tech Report's full review.
"Asus' Transformer Book T300 Chi combines Intel's Core M processor with a 12.5" high-PPI display. The tablet half of this detachable 2-in-1 is thinner than the iPad Air, and it's backed by a keyboard dock that attaches with neodymium magnets. Read on to see what the T300 Chi is like as a tablet and notebook."

After seeing it at CES this January, one our most anticipated products became the Lenovo Lavie-Z laptop. Born out of a partnership between NEC and Lenovo, the Lavie-Z promises to be the world's lightest laptop.
Our old-school postage scale doesn't have the accuracy to reach the 1.87lb that Lenovo clocks the Lavie-Z in at
Even after using the machine breiefly at CES, it is difficult to put into words what picking up a sub-2lb laptop is really like. Even after using the machine off and on today, it still feels like it's not a real machine. Lenovo and NEC have been able to accomplish this weight shedding through the use of a Lithium-Magnisum composite for the external housing of the machine, which seems durable, yet is incredibly light.
This may be a lightweight machine, but the specifications aren't compromised over other ultrabooks. The Lavie-Z is only listed in one configuration on Lenovo's site currently, but it's a high end one. A Broadwell Intel i7-5500U dual core processor, 8GB of RAM, a 2560x1440 IGZO display, 256GB SATA M.2 Samsung SSD, and Intel 802.11AC wireless make up this machine. At $1500 for this configuration, there doesn't seem to be much of a markup over other i7-equipped ultrabooks.
We'll of course put the Lavie-Z through our normal paces including performance and battery life, and we certainly hope they live up to the striking first impressions of this laptop.
Stay tuned for our full review in the coming weeks!
