A monitor for those that like it long

It takes a lot to really impress someone that sits in front of dual 2560x1600 30-in IPS screens all day, but the LG 34UM95 did just that. With a 34-in diagonal 3440x1440 resolution panel forming a 21:9 aspect ratio, built on LG IPS technology for flawless viewing angles, this monitor creates a work and gaming experience that is basically unmatched in today's market. Whether you need to open up a half-dozen Excel or Word documents, keep an eye on your Twitter feed while looking at 12 browsers or run games at near Eyefinity/Surround levels without bezels, the LG 34UM95 is a perfect option.

Originally priced north of $1200, the 34UM95 and many in LG's 21:9 lineup have dropped in price considerably, giving them more avenues into users' homes. There are obvious gaming advantages to the 34-in display compared to a pair of 1920x1080 panels (no bezel, 20% more pixels) but if you have a pair of 2560x1440 screens you are going to be giving up a bit. Some games might not handle 21:9 resolutions well either, just as we continue to see Eyefinity/Surround unsupported occasionally.

Productivity users will immediately see an improvement, both for those us inundated with spreadsheets, web pages and text documents as well as the more creative types with Adobe Premiere timelines. I know that Ken would definitely have approved us keeping this monitor here at the office for his use.

It's more than just a branding issue

As a part of my look at the first wave of AMD FreeSync monitors hitting the market, I wrote an analysis of how the competing technologies of FreeSync and G-Sync differ from one another. It was a complex topic that I tried to state in as succinct a fashion as possible given the time constraints and that the article subject was on FreeSync specifically. I'm going to include a portion of that discussion here, to recap:

First, we need to look inside the VRR window, the zone in which the monitor and AMD claims that variable refresh should be working without tears and without stutter. On the LG 34UM67 for example, that range is 48-75 Hz, so frame rates between 48 FPS and 75 FPS should be smooth. Next we want to look above the window, or at frame rates above the 75 Hz maximum refresh rate of the window. Finally, and maybe most importantly, we need to look below the window, at frame rates under the minimum rated variable refresh target, in this example it would be 48 FPS.

AMD FreeSync offers more flexibility for the gamer than G-Sync around this VRR window. For both above and below the variable refresh area, AMD allows gamers to continue to select a VSync enabled or disabled setting. That setting will be handled as you are used to it today when your game frame rate extends outside the VRR window. So, for our 34UM67 monitor example, if your game is capable of rendering at a frame rate of 85 FPS then you will either see tearing on your screen (if you have VSync disabled) or you will get a static frame rate of 75 FPS, matching the top refresh rate of the panel itself. If your game is rendering at 40 FPS, lower than the minimum VRR window, then you will again see the result of tearing (with VSync off) or the potential for stutter and hitching (with VSync on).

But what happens with this FreeSync monitor and theoretical G-Sync monitor below the window? AMD’s implementation means that you get the option of disabling or enabling VSync.  For the 34UM67 as soon as your game frame rate drops under 48 FPS you will either see tearing on your screen or you will begin to see hints of stutter and judder as the typical (and previously mentioned) VSync concerns again crop their head up. At lower frame rates (below the window) these artifacts will actually impact your gaming experience much more dramatically than at higher frame rates (above the window).

G-Sync treats this “below the window” scenario very differently. Rather than reverting to VSync on or off, the module in the G-Sync display is responsible for auto-refreshing the screen if the frame rate dips below the minimum refresh of the panel that would otherwise be affected by flicker. So, in a 30-144 Hz G-Sync monitor, we have measured that when the frame rate actually gets to 29 FPS, the display is actually refreshing at 58 Hz, each frame being “drawn” one extra instance to avoid flicker of the pixels but still maintains a tear free and stutter free animation. If the frame rate dips to 25 FPS, then the screen draws at 50 Hz. If the frame rate drops to something more extreme like 14 FPS, we actually see the module quadruple drawing the frame, taking the refresh rate back to 56 Hz. It’s a clever trick that keeps the VRR goals and prevents a degradation of the gaming experience. But, this method requires a local frame buffer and requires logic on the display controller to work. Hence, the current implementation in a G-Sync module.

As you can see, the topic is complicated. So Allyn and I (and an aging analog oscilloscope) decided to take it upon ourselves to try and understand and teach the implementation differences with the help of some science. The video below is where the heart of this story is focused, though I have some visual aids embedded after it.

Still not clear on what this means for frame rates and refresh rates on current FreeSync and G-Sync monitors? Maybe this will help.

Specifications

The perfect laptop; it is every manufacturer’s goal. Obviously no one has gotten there yet (or we would have all stopped writing reviews of them). At CES this past January, we got our first glimpse of a new flagship Ultrabook from Dell: the XPS 13. It got immediate attention for some of the physical characteristics it included, like an ultra-thin bezel and a 13-in screen in the body of a typical 11-in laptop, all while being built in a sleek thin and light design. It’s not a gaming machine, despite what you might remember from the XPS line, but the Intel Core-series Broadwell-U processor keeps performance speedy in standard computing tasks.

As a frequent traveler that tends to err on the side of thin and light designs, as opposed to high performance notebooks with discrete graphics, the Dell XPS 13 is immediately compelling on a personal level as well. I have long been known as a fan of what Lenovo builds for this space, trusting my work machine requirements to the ThinkPad line for years and year. Dell’s new XPS 13 is a strong contender to take away that top spot for me and perhaps force me down the path of an upgrade of my own. So, you might consider this review as my personal thesis on the viability of said change.

The Dell XPS 13 Specifications

First, make sure as you hunt around the web for information on the XPS 13 that you are focusing on the new 2015 model. Much like we see from Apple, Dell reuses model names and that can cause confusion unless you know what specifications to look for or exactly what sub-model you need. Trust me, the new XPS 13 is much better than anything that existed before.

GM200 Specifications

With the release of the GeForce GTX 980 back in September of 2014, NVIDIA took the lead in performance with single GPU graphics cards. The GTX 980 and GTX 970 were both impressive options. The GTX 970 offered better performance than the R9 290 as did the GTX 980 compared to the R9 290X; on top of that, both did so while running at lower power consumption and while including new features like DX12 feature level support, HDMI 2.0 and MFAA (multi-frame antialiasing). Because of those factors, the GTX 980 and GTX 970 were fantastic sellers, helping to push NVIDIA’s market share over 75% as of the 4th quarter of 2014.

But in the back of our mind, and in the minds of many NVIDIA fans, we knew that the company had another GPU it was holding on to: the bigger, badder version of Maxwell. The only question was going to be WHEN the company would release it and sell us a new flagship GeForce card. In most instances, this decision is based on the competitive landscape, such as when AMD might be finally updating its Radeon R9 290X Hawaii family of products with the rumored R9 390X. Perhaps NVIDIA is tired of waiting or maybe the strategy is to launch soon before Fiji GPUs make their debut. Either way, NVIDIA officially took the wraps off of the new GeForce GTX TITAN X at the Game Developers Conference two weeks ago.

At the session hosted by Epic Games’ Tim Sweeney, NVIDIA CEO Jen-Hsun Huang arrived when Tim lamented about needing more GPU horsepower for their UE4 content. In his hands he had the first TITAN X GPU and talked about only a couple of specifications: the card would have 12GB of memory and it would be based on a GPU with 8 billion transistors.

Since that day, you have likely seen picture after picture, rumor after rumor, about specifications, pricing and performance. Wait no longer: the GeForce GTX TITAN X is here. With a $999 price tag and a GPU with 3072 CUDA cores, we clearly have a new king of the court.
