Gaming on PCs used to be restricted to desktop computers equipped with a dedicated graphics card connected to a display, much in the same way that a games console works with a TV. Recent advances in technology have enabled manufacturers to equip laptops with increasing levels of graphics power without them being too bulky or heavy.

NVIDIA refreshed its range of graphics cards recently with the introduction of a number of new models for performance desktop PCs. Four new GeForces have been released in quick succession. The Titan X, GTX 1080, GTX 1070 and GTX 1060, all based on the new, efficient Pascal architecture, have set new levels of performance in each segment.

Choosing a monitor is not an easy decision to make, and not just because of the large number of variations in resolution, refresh rates, sizes and connectivity options. There are also varying panel technologies used to form each display that need to be considered. These panel technologies can be grouped into three broad categories which cover the vast majority of monitors sold in the consumer market.

Nvidia launched the GeForce GTX 980M and GeForce GTX 970M mobile GPUs, based on the latest Maxwell graphics architecture, in October 2014. More recently, in January 2015, the GeForce GTX 965M was released to laptop makers. These new mobile GPUs provide class-leading gaming performance for a wide variety of premium laptops.

G-SYNC works in a surprisingly simple way - it calculates how long the present frame takes to compute and then, crucially, varies the refresh rate of the monitor to match. It works between a minimum of 33.3ms (30fps) and the maximum supported refresh of the display. The key takeaway here is that the graphics card and monitor are both synced up to one another - the monitor doesn't have the limitations imposed by a rigid, fixed-rate scanning routine.

Modern desktop computers and notebooks comprise of a CPU, motherboard, graphics, storage, and, usually an optical drive. Computers have a number of ports and sockets that enable the user to plug-in various peripherals such as a printer, USB mouse, or, perhaps most importantly of all, an Internet connection.

What’s the most important part of your PC system? Its processor? The mainboard? Maybe the power supply? You’d only have a case if you thought it’s the PSU. That cornerstone of a PC system is the most important part of the PC system as concerns what’s in the chassis, which might surprise you, but it’s definitely the devices you use to interact with a PC which are absolutely top dog.

Now shipping with all but the cheapest complete PCs are LCD monitors. Advances in display manufacturing and associated cost reductions with economies of scale have brought LCD monitors into the mainstream, shipping with budget systems that start at just £400. LCD monitors come in all shapes and sizes, have differing resolutions and inputs. The purpose of this TekSpek is to provide a basic understanding of how LCDs work, delineate their desirable features, and to offer basic buying advice.

As you’ll all likely know by now, DVI is the current standard for connection of a PC or other display generator to a digital display output. You’ll recognise the multi-pin connector and know that almost all modern LCD displays have the corresponding input connector, for feeding from your PC. But do you know how DVI works? This TekSpek seeks to teach you how.

If you’re the least bit interested in graphics cards, we’re sure that you’ve heard the terms SLI and CrossFire bandied about recently. Touted as a means of achieving maximum 3D performance by, effectively, using two or more graphics cards in tandem, multi-GPU technology is here to stay. With that in mind, let’s take a closer look SLI and CrossFire; the two competing multi-GPU solutions from NVIDIA and ATI Technologies, respectively.

The array of joysticks on offer is massive with price varying almost as much as the styles of sticks themselves. The trick is buying a stick suited to your needs and not something that either doesn’t do what you need or has extras that you’ll never use. The reason there are so many sticks on the market is because they each fulfill a particular niche… so let’s take a stroll through the joystick forest and sort out the slender silver birches from the mighty oaks….

Whether the broadcasters are going HD or not, TV sets and projectors are arriving thick and fast which claim to support higher resolutions than regular telly. But HDTV is far from just one standard – it incorporates a couple of different resolutions, two different scanning modes, and a number of different frame rates. In this article, we present a guide to what all the terms actually mean.

There’s a lot more to High Definition than just having the ability to run your screen at the right resolution. With more than one type of connection available, and the thorny subject of signal encryption to contend with, just because your monitor and graphics are capable of 1,920 x 1,080 or better does not necessarily mean they will be able to display HDTV in all its glory.

It’s a debate that’ll carry on until we have thought controlled PCs that respond to our cerebral synapses, but until then the argument over how best to move that in-game version of ourselves will continue.
