4k Meets 144 Hz with Nvidia G-Sync Displays

Nvidia is expected to release 4k, 144 Hz monitors with G-Sync and HDR. The displays are under the Asus and Acer brands. The combination of these specs sounds like a major boon for competitive online gaming, but it would be interesting to see if reviewers confirm that.



Where’s the HDR Monitors Already?

I’ve been across a lot of forums and comment sections that talk about 4K being the future, followed by 8K after that when it comes to monitor technology. However, if you do the math for what pixels the human eye can actually see, 1440p is all anyone should ever need. Why is 4K so much better then? The answer lies in what colors the pixels can actually reproduce. Because of this, more pixels end up looking better color wise once they’re grouped up, even though the human eye can’t discern the individual pixels at a normal viewing distance. The patches of color start showing more variance at higher resolutions, tricking us into thinking it’s the higher resolution itself that’s better. AMD stated at CES, earlier this year, that we need better pixels. While the human eye may not work well compared to the magnifying focus of an eagle eye, what it can see as far as the range of colors is concerned is pretty amazing. If pixels aren’t reproducing colors to the extent that the human eye can see them, shades blur together making images look flat, rather than vibrant and varied. This is where High Dynamic Range (HDR) comes into play. HDR can almost reproduce all the colors the human eye can see on an individual pixel basis. This means that a 1080p monitor can actually look better than a 4K that isn’t using HDR. Some of you may be reading this and thinking that it sounds good on paper, but that doesn’t mean it will actually translate to ...



Kingston 64GB SDXC Class 3 Memory Card & USB 3.0 MobileLite G3 Review

During our visit with Kingston at CES 2014 this year, we had a chance to sit down with them to talk about the new and up-coming flash memory cards that are designed for HD Media use. With the advancing and growing media recording industry, faster and more reliable flash memory cards are on high demand, especially those looking for high capacity to store everything on one card. With the standards of 1080p recording, Ultra HD 2160p and 3D/2K&4K resolutions on the horizon, the number of pixels on recording devices can no longer suffice with the slower and lower capacity memory cards. It has been a couple of months since the initial talk and today we finally got our hands on the Kingston 64GB SDXC Class 3 UHS-I U3 flash memory card. Kingston developed this particular card in three available sizes, 16GB, 32GB and 64GB. The last one will be the memory card we take a look at today. Kingston was also nice enough to send us the Kingston Mobile Lite G3 SD and Micro-SD card USB 3.0 reader as an extra bonus to be able to test the memory card today. With the speed advancements in the SDXC memory card, we wanted to make sure there are no bottlenecks.



 
 
 
 
 

VisionTek Radeon R9-280X

Introduction   In this ever-blossoming technology industry there are smaller companies that are often overshadowed by their behemoth competitors. There are many reasons why this occurs but one of the most common assumptions is that the smaller company is lower quality. The thinking has been that the smaller guy can’t make a product as well as the bigger guy. VisionTek has been striving to prove that assumption to be false. They believe they can be a smaller company yet still offer quality and value. VisionTek sent us the new Radeon R9-280X AMD based GPU to see how well their promise holds up. We will take a moment to learn about VisionTek before we put the R9-280X through some tests.   http://www.visiontekproducts.com/ VisionTek Products, LLC is a leading supplier of personal computer enhancement products to retailers and consumers.

Sapphire Vapor-X R9 270X

   Introduction   One of the keys to a successful technology business is reaching out to customers. Get them interested in the product or services you are offering, and then close the deal by selling them the product or service. In this day and age, which is full of technology junkies, this seems incredibly easy. In most cases it is that easy. Something new and shiny hits the market and we drool on our keyboards. However there are some folks who remain reluctant for a very important reason, follow-through. They wonder if a company will follow-through by providing the best product or service for their hard earned money? If the company accomplishes the sometimes unspoken promise, then the deal is truly complete. There is a company that has a proven track record of doing just that year after year, product after product. Today we will see if Sapphire Technology can continue the tradition of providing a great value and performance for your hard earned dollars. Following the launch of the new AMD Hawaii based GPUs, Sapphire sent us its new Vapor-X R9-270x so we can measure its commitment to excellence. From Innovator to Excellence over 10 years! SAPPHIRE Technology was first formed as a manufacturer and global supplier of graphics cards when ATI (now a division of AMD) adopted the Add-in Board partner (AIB) model for delivering its technology to market. SAPPHIRE has consistently been the market leader with its graphics products. More recently the SAPPHIRE product rang...



 
 
 
 
 

Gigabyte Windforce R9-27xOC-2GD

    Introduction:   There has been a flurry of guesses, assumptions, predictions and all out nonsense relating to the new AMD R9 and R7 series of GPUs. Well the day has come where we can confirm and/or lay to rest most of the items previously listed. Launch day is here! The internet has been on fire for the last few days about the new AMD GPUs for multiple reasons: performance increases, newer technology features and most of all prices. We all love to finally know how much something will cost so we know how much work it will be to obtain. We love it even more when we get more performance per dollar. That ratio seems to be the driving force behind the new AMD cards released today. Unfortunately we don’t get to see all of the new features of the Hawaii based cards, but I will cover some of those here. What we do get to see is a shift towards a model based on the idea that everyone/anyone can be a gamer. The R9-270x is focused on the mainstream segment of the market where most of the market share resides. Lowering the initial cost of entering the PC gaming segment while still allowing them to play most games with high settings can be a big win for the industry. More people will buy games and will upgrade other hardware. They might also add a 2nd GPU when they decide one will no longer feed their thirst for higher levels of detail and resolution. Many, like myself, are eager to see what the new- “New era of gaming” is all about. Can it possibly live up...
