Acer's upcoming ultra-widescreen 34-inch G-SYNC gaming monitor, the XR341CKA, will have multiple inputs according to a report published by TFT Central, which indicates possible changes to the G-SYNC V2 module as previous displays only provided one input.

The Acer XR341CKA is a variant of the XR341CK, a FreeSync monitor that contains an identical panel. The IPS panel in both monitors is rated up to 75Hz refresh with a resolution of 3440x1440, and a contrast ratio of 1000:1 with 8-bit + FRC (effective 10-bit) color depth. The big story here is of course the G-SYNC module, and though we don't know the specific implementation yet is will be interesting to see what the input support of version 2 G-SYNC displays will be. According to TFT Central the FreeSync (CK) variant of the XR341 offers "HDMI 2.0 (MHL), DisplayPort, Mini DP and DP out connections," and "it will support daisy chaining via the DP out port and also PiP and PbP functions".

In contrast the G-SYNC variant (CKA) of the XR341 offers "DisplayPort, but also an additional HDMI 1.4 video connection...(and) will also support ULMB (Ultra Low Motion Blur)." TFT Central points out that this detail "would mark the first G-sync screen we've seen with more than one connection, so we will be interested to see how this works." If indeed this is a single module solution it is possible that NVIDIA has made changes with the second-gen G-SYNC module to allow for more than one input. We will have to wait and see, unless more details about this V2 module are forthcoming.

Acer's Latest 15.6" Chromebook Powered By Core i5 (Broadwell-U) Processor

Subject: General Tech | March 26, 2015 - 01:34 AM |
Tagged: core i5, Chromebook, chrome os, broadwell-u, acer

Acer is adding an updated Chromebook to its education-focused C910 lineup. The new Acer C910-54M1 ups the hardware ante by incorporating a Broadwell-U based Intel Core i5 processor which will make this the fastest Chromebook on the market (for what that's worth). 

This new C910 remains aimed at schools and businesses with a sturdy frame, large (for a Chromebook) 15.6" (up to) 1080p display, and eight hours of battery life. Below the display sits an island style keyboard and a large trackpad. Except for the arrow keys, Acer was able to use "regular" sized keys and did not shrink the shift or backspace keys which can be annoying. A webcam and two large upward facing speakers are also present on the C910.

External I/O includes:

  • 1 x USB 3.0
  • 1 x USB 2.0
  • 1 x HDMI
  • 1 x SD card reader

The port selection is about what one would expect from a Chromebook, but the inclusion of USB 3.0 is welcome for accessing external storage.

Internally, the C910 Chromebook is powered by a dual core (four threads with Hyper-Threading) Broadwell-U Core i5 5200U processor clocked at 2.2GHz base and up to 2.7GHz Turbo Boost with a 15W TDP and 3MB cache. This particular processor includes Intel HD Graphics 5500 clocked at up to 900 MHz. Other hardware includes 4GB DDR3 memory and a 32GB SSD. Wireless hardware includes 802.11ac Wi-Fi and Bluetooth 4.0. 

Acer's new Chromebook is big and powerful, but will the increased hardware provide a noticeably better Chrome OS experience? Intel (naturally) seems to think so with its push to get Core i3 processors into Chromebooks last year. The Broadwell-U Core i5 should be just as fast (maybe even a bit faster with smoother UX and graphics) while sipping power. The alleged eight hours of battery life is impressive as well considering. The downside, because of course there always is one, is pricing. The C910-54M1 will be available in April with a 1080p display for $500. 

At that price point, it is squarely in budget Windows notebook territory as well as high end convertible (e.g. Bay Trail) tablet territory. It will be interesting to see how it ends up doing compared to the other options which each have their own trade offs.

What is FreeSync?

FreeSync: What began as merely a term for AMD’s plans to counter NVIDIA’s launch of G-Sync (and mocking play on NVIDIA’s trade name) has finally come to fruition, keeping the name - and the attitude. As we have discussed, AMD’s Mantle API was crucial to pushing the industry in the correct and necessary direction for lower level APIs, though NVIDIA’s G-Sync deserves the same credit for recognizing and imparting the necessity of a move to a variable refresh display technology. Variable refresh displays can fundamentally change the way that PC gaming looks and feels when they are built correctly and implemented with care, and we have seen that time and time again with many different G-Sync enabled monitors at our offices. It might finally be time to make the same claims about FreeSync.

But what exactly is FreeSync? AMD has been discussing it since CES in early 2014, claiming that they would bypass the idea of a custom module that needs to be used by a monitor to support VRR, and instead go the route of open standards using a modification to DisplayPort 1.2a from VESA. FreeSync is based on AdaptiveSync, an optional portion of the DP standard that enables a variable refresh rate courtesy of expanding the vBlank timings of a display, and it also provides a way to updating EDID (display ID information) to facilitate communication of these settings to the graphics card. FreeSync itself is simply the AMD brand for this implementation, combining the monitors with correctly implemented drivers and GPUs that support the variable refresh technology.

disp4.jpg

A set of three new FreeSync monitors from Acer, LG and BenQ.

Fundamentally, FreeSync works in a very similar fashion to G-Sync, utilizing the idea of the vBlank timings of a monitor to change how and when it updates the screen. The vBlank signal is what tells the monitor to begin drawing the next frame, representing the end of the current data set and marking the beginning of a new one. By varying the length of time this vBlank signal is set to, you can force the monitor to wait any amount of time necessary, allowing the GPU to end the vBlank instance exactly when a new frame is done drawing. The result is a variable refresh rate monitor, one that is in tune with the GPU render rate, rather than opposed to it. Why is that important? I wrote in great detail about this previously, and it still applies in this case:

The idea of G-Sync (and FreeSync) is pretty easy to understand, though the implementation method can get a bit more hairy. G-Sync (and FreeSync) introduces a variable refresh rate to a monitor, allowing the display to refresh at wide range of rates rather than at fixed intervals. More importantly, rather than the monitor dictating what rate this refresh occurs at to the PC, the graphics now tells the monitor when to refresh in a properly configured G-Sync (and FreeSync) setup. This allows a monitor to match the refresh rate of the screen to the draw rate of the game being played (frames per second) and that simple change drastically improves the gaming experience for several reasons.

slides01.jpg

Gamers today are likely to be very familiar with V-Sync, short for vertical sync, which is an option in your graphics card’s control panel and in your game options menu. When enabled, it forces the monitor to draw a new image on the screen at a fixed interval. In theory, this would work well and the image is presented to the gamer without artifacts. The problem is that games that are played and rendered in real time rarely fall into a very specific frame rate. With only a couple of exceptions, games frame rates will fluctuate based on the activity happening on the screen: a rush of enemies, a changed camera angle, an explosion or falling building. Instantaneous frame rates can vary drastically, from 30, to 60, to 90, and force the image to be displayed only at set fractions of the monitor's refresh rate, which causes problems.

CES 2015: Acer Aspire V 17 Nitro with Intel RealSense 3D

Intel's “Perceptual Computing” initiative, later branded Intel RealSense 3D, is beginning to be integrated with consumer electronics. For a while now, developers could pick up a Creative Labs-produced SDK with a camera, depth sensor, and dual microphones (in an array) for $99 USD. We will probably hear more about it tomorrow during Intel's CES 2015 Keynote at 7:30pm EST. Hopefully, they will also have some compelling software to go along with it.

Acer-Aspire-V-Nitro-VN7-791-photogallery-01.png

This is the previous model. For the new version, see the video below.

But this announcement is from Acer, which will launch a new Aspire V 17 Nitro notebook with a built-in Intel RealSense 3D camera. The company believes that the technology will be used for controlling games, or scanning your face and objects for 3D printing. I'm... not so sure about printing my face, but I could see facial recognition being an interesting feature of upcoming software, even if it is not good enough for secure authentication purposes.

The laptop itself will be built on a Haswell-based Core i7-4710HQ that is paired with a GeForce GTX 860M GPU (4GB GDDR5). It can be configured with up to 16GB of system memory, up to 256GB of SSD space, and up to a 1TB secondary hard drive. As the name suggests, the display is a 17-inch IPS panel, which is apparently not a touch-screen.

The Acer Aspire V 17 Nitro will be available this month, but no pricing information is available. The previous model is still on Acer's website for $1400 USD, without RealSense 3D.

Today Acer has announced two new gaming monitors with "world first" designs. First we have the XB270HU, which is the world’s first NVIDIA G-SYNC gaming monitor with an IPS panel. This is a big step for a category that has predominantly featured TN panels, though it was not stated what the response time of the IPS panel in use might be. We can expect 178° viewing angles and that nice IPS color accuracy, however. The XB270HU also features tilt, swivel, and height adjustment.

IPS provides realistic color, wide viewing angles, and this sweet logo

Next is the Acer XG270HU (yes, this is a different model name), which Acer says is "the world's first gaming monitor with an edge-to-edge frameless display", which would allow for gapless multi-monitor setups. This one does not feature IPS, but it has the advantage of a 1 ms response time. Inputs will include HDMI 2.0, DVI, and DisplayPort 1.2. The other added feature of the XG270HU is Acer "EyeProtect technology", which "eliminates screen flicker through a stable supply of power", as well as proprietary non-glare and screen dimming features. Both XB270HU and XG270HU monitors have 27-inch displays with WQHD (2560 x 1440) resolution and 144Hz refresh rates.

These will available globally and begin shipping in March 2015.

Technical Specifications

NVIDIA's G-Sync technology and the monitors that integrate it continue to be one of hottest discussion topics surrounding PC technology and PC gaming. We at PC Perspective have dived into the world of variable refresh rate displays in great detail, discussing the technological reasons for it's existence, talking with co-creator Tom Petersen in studio, doing the first triple-panel Surround G-Sync testing as well as reviewing several different G-Sync monitor's available on the market. We were even the first to find the reason behind the reported flickering a 0 FPS on G-Sync monitors.

IMG_0643.JPG

A lot of has happened in the world of displays in the year or more since NVIDIA first announced G-Sync technology including a proliferation of low cost 4K panels as well as discussion of FreeSync, AMD's standards-based alternative to G-Sync. We are still waiting for our first hands on time (other than a static demo) with monitors supporting FreeSync / AdaptiveSync and it is quite likely that will occur at CES this January. If it doesn't, AMD is going to have some serious explaining to do...

But today we are looking at the new Acer XB270H, a 1920x1080 27-in monitor with G-Sync support and a 144 Hz refresh rate; a unique combination. In fact, there is no other 27-in 144 Hz 1080p monitor on the market that we are aware of after a quick search of Newegg.com and Amazon.com. But does this monitor offer the same kind of experience as the ASUS ROG Swift PG278Q or even the Acer XB280HK 4K G-Sync panels?

Rumor: 15.4" Broadwell-U Chromebooks Are Coming

Subject: General Tech, Systems | December 29, 2014 - 01:42 PM |
Tagged: laptop, google, dell, ChromeOS, Chromebook, chrome, acer

According to DigiTimes via The Tech Report, because of course DigiTimes, we should receive 15.4-inch Chromebooks in the near future. Their sources claim that both Acer and Dell have products planned with that operating system, in that size, and will cost less then $300. The Acer system is expected in March 2015 with Dell scheduled for some time in the first half of 2015.

12-failslow-Chrome.png

One part that stands out for me is the maximum price of $300. The claim is that this is a Google mandated ceiling for Chromebooks with up-to Core i3 performance. This is troubling for two reasons. First, depending on the details, it might dance around inside the minefield of price-fixing laws, although I am sure that Google is doing this in a legally. I mean, Apple has been getting away with enforcing maximum retail prices of iPods and iOS devices for around a decade and I believe console manufacturers do about the same.

Second, and more importantly, it limits the ability for manufacturers to be creative and innovative, which is the major advantage of an open ecosystem. Being a web browser-based platform, there is already constraints on what manufacturers can implement. Sure, Google is probably open to communication with their partnered hardware vendors, but it is uncomfortable none-the-less. I could use the Nexus Q as an example of an experiment but unfortunately it was neither a hit nor did it cost over $300. Sure, they could add a more powerful processor to escape that clause but it is still

These Chromebooks are expected to launch in the early half of 2015.
