PC Gaming 101: Part 5: Gaming Monitor Buyer's guide

PC gaming is quite big in India. As games become more intense and compelling, gamers find themselves wanting the latest and greatest hardware to run these games smoothly. That being said, the majority of gamers wanting to build or upgrade their machines don’t have much of a clue, and are often at the mercy of vendors and salesmen, due to which, more often than not, they end up making the wrong decisions. This is an attempt to address this lack of information, and help all PC gamers make the best of their resources. This is PC GAMING 101.

 

If you own and regularly use a PC, you know what a minitor is. However, when it comes to gaming, not all monitors are built equally. So, what makes a monitor "good for gaming" ? (Well for starters it should connect to a device that runs videogames.) Let's have a look at the things you should look out for, while choosing a monitor for your gaming setup: 

1. Inputs 

 

Most gaming monitors these days have DisplayPort, HDMI and DVI input ports, or a combination of the three. (You can read more about display technologies and standards in Part 4, here). If you're gaming on a PC, and you want to keep things as simple as possible, you should go with DVI and DisplayPort with confidence. HDMI will work fine, unless you want the resolution to be higher than 1080P, or a refresh rate over 60Hz. HDMI 2.0 is coming out soon to address these issues. Not that HDMI inputs are totally useless though, you can use them to connect secondary gaming devices such as gaming consoles and switch between your devices as you choose. 

2. Size Matters 

Yes, a monitor's size does matter, but not for the reasons most people think it does. A larger monitor just puts a larger image in front of you, and isn't any more difficult for your graphics card to power. So you should pick a size that's comfortable for you, for the distance you want to sit from it. The spec that determines how hard it is to power the monitor, is the resolution. A 24 inch 4K monitor will be about 4 times more difficult to drive than even an 80 inch 1080P "Full HD" TV, because of the sheer number of pixels. Higher resolution monitors deliver a clearer, more "retina-like" display so resolution isn't a problem, in and of itself. It's just a factor you need to consider in your overall build/upgrade budget. 

Now that we've gone through the basics of monitors and displays, let's look at what makes a monitor "good for gaming". 

Response Time  

The rendering process of pixels on an LCD/LED display is very different from the old, tube style CRT monitors, and when the image updates, the pixels gradually shift from one colour to another. So, the slower the pixels of the monitor, the more "motion blur" or ugly streaking that you'll see behind moving objects on the screen. 

So, while buying a monitor for gaming, look for a monitor with a "Grey to Grey" response time of

8-16 milliseconds for  casual use

1-2 ms for competitive use.  

Refresh Rate 

60Hz versus 144 Hz

Expressed in Hertz, the refresh rate is the number of times an image is sent to the display, every second. If your eyes are getting more updates per second, you're getting information slightly faster than your opponent. It's a definite advantage, and the fastest monitors these days can run at upto 144 Hz, at 1080P. That means you can get screen updates upto 10 milliseconds faster than your opponent using a 60 Hz display. 

Input Lag

Now, this is a spec that most manufacturerd don't report, but is really quite important. When the CPU sends signals to the monitor, the monotor needs to translate that information into a format that the panel can understand. This processing introduces a delay which means that you could be seeing an individial frame that is anywhere from a few milliseconds later than it was output by your graphics card, all the way upto 50 milliseconds later, or more. For competitive use, look for a monitor that has an input lag of less than 10 milliseconds. But don't just take the manufacturer's word for it, LCD manufacturers are notorious for inventing completely new specifications to suit their marketing purposes. So, be sure to check out sites like Blur Busters to get the latest info and specs on gaming displays. 

Other Features

Apart from the factirs mentioned above, there are other factors to look out for as well, such as 

Now, if this guide raised more questions than it answered, or you'd just like to go hands-on and choose which specs matter for you, just check out online forums, they might really help out.

PC Gaming 101: Part 4: Display Tech Explained

PC gaming is quite big in India. As games become more intense and compelling, gamers find themselves wanting the latest and greatest hardware to run these games smoothly. That being said, the majority of gamers wanting to build or upgrade their machines don’t have much of a clue, and are often at the mercy of vendors and salesmen, due to which, more often than not, they end up making the wrong decisions. This is an attempt to address this lack of information, and help all PC gamers make the best of their resources. This is PC GAMING 101.

When building or upgrading a PC, it’s essential to know what kinds of display outputs it supports. The issue here is there’s no single standard display technology and thus it’s easy to get confused due to the different standards. On the back of your PC or Graphics Card you’ll see a host of different connectors. Let’s see the difference between these different connectors and what kind of display technology you should invest in depending on your needs:

1. VGA

The standard "blue cable" VGA
The standard "blue cable" VGA

 

 

 

 

The oldest standard in existence, Visual Graphics Array or VGA was first introduced in 1987. This is what usually what comes to mind when someone mentions “display cable”. The standard blue colored 15 pin connector in its typical trapezoid shape, VGA cables carry analog signals and thus the signal quality greatly depends on the quality of the cable. This standard is actually obsolete, and there’s a limit to the resolution VGA cables can support. However, there are a whole lot of Analog monitors and projectors out there, especially in India where VGA is used in most scenarios. If you're

a gamer, and you're rocking a VGA display, it’s probably time for you to invest in a better display, as in the future; higher end Graphics Cards and Gaming PCs will not be compatible. Even today, you'll have to search a lot to find a Graphics card with VGA output. You can always use a VGA adapter, but unless you really can’t upgrade, it’s better to move away from the now seemingly stone-age VGA.

 

2. DVI

The different kinds of DVI connectors
The different kinds of DVI connectors

The current reigning champion of display outputs, DVI, or Digital Visual Interface is one of the most ubiquitous successors to VGA. DVI comes in different flavors, Namely DVI-D (digital only), DVI-A (analog only), DVI-I (digital and analog). However, DVI-D is what you’ll most probably find and use. DVI marks the beginning of Digital signals being used in Display technology, and offers good compatibility with the older VGA standard, with DVI to VGA adaptors available very easily (for use with DVI-A and DVI-I ).

Because DVI is both backwards and forwards compatible using easy to use adapters, it's very convenient

Most graphics cards come with multiple DVI connectors, and most modern displays have DVI support out of the box. DVI offers higher data rates, support for higher resolutions, and is found in all competent displays and Graphics cards of today. There are two kinds of DVI connectors- single link and dual link. Single link DVI connectors allow you to support a display of 1920×1200 at 60Hz, whereas dual link allows you to support up to either 2560×1600 at 60 Hz (30 inch monitor resolution) or 1920×1200 at 120Hz (for 3D gaming). The absence of analog technology means you're no longer tied down by the cable quality, and unless you're running monitors at a very long distance, any standard cable can get you optimal image quality using DVI. Also, it’s very easy to convert it into other standards, older or newer- all you need is an adapter. However, it’s also getting old now the race for the next generation of high-resolution display technology has begun, and the time when DVI becomes a thing of the past is not too far away.

3. HDMI

HDMI is the new, ubiquitous standard
HDMI is the new, ubiquitous standard

As spoken of before, the next generation of high-resolution display technology is upon us, and HDMI or High Definition Multimedia Interface is at the forefront of it. HDMI is basically designed to be a replacement for existing analog video standards. This standard was put together by a lot of big name companies working together, and it comes in different formats and port sizes as well although the standard type-A HDMI cable is used in most TVs and Monitors. It offers uncompressed digital audio and video data in a TV or PC video format. The rise in prominence of HD Televisions and with the “Full HD” moniker being thrown about a lot these days means HDMI is getting a huge push in terms of marketing, and it surely is a competent standard. It’s not exactly a PC display standard, but If you're investing in an HD monitor for your PC it will definitely have HDMI support. The image quality and signal is at most times identical to DVI. It has backward compatibility with DVI, and the connector is much more compact. Currently in version 2.0, HDMI offers a wide gamut of features including support for good old S-RGB, Ethernet, HD- ready Blu-ray or 3D ready TVs, and even 4K resolution at 60 FPS.

4. DisplayPort

DisplayPort- the newest entrant in the Display Interface scenario
DisplayPort- the newest entrant in the Display Interface scenario

The newest of the standards out there, DisplayPort is royalty free, which means that while there’s a royalty behind every HDMI cable that’s produced, DisplayPort based interfaces are free to manufacture without any such royalties which has made it quite lucrative for manufacturers to use. The DisplayPort connectors are surely the easiest to use of the lot- they do away with the old-school screw locking system in VGA, and aren't as insecure as the non-locking HDMI connectors, which are known to disconnect easily due to it. It also offers support for resolution even higher than HDMI, a maximum of 3840×2160 at 60 Hz. Manufacturers have begun to include DisplayPort interfaces in the latest Graphics Cards, and it surely seems like a promising prospect for the future. However, the main issue with DisplayPort is that it isn't compatible with any other display standard, i.e. there aren't any easy to use adapters available that can convert DisplayPort to any other current standard. DisplayPort has two sizes- the standard and mini DisplayPort. Manufacturers often use mini DisplayPort as it takes up much lesser space on the Output Interface of the card, thus making multi-display structures running off the same video card possible.

HDMI vs DisplayPort

So, you’re looking to be on the absolute bleeding edge of display technology and want the latest and greatest display at the highest possible resolution. That narrows down your search to HDMI and DisplayPort. Which standard should you invest in?

When to use HDMI: If you’re looking at a setup that is basically a single screen, running at 1920*1200, and the display is not at much of a distance from the video output, you’re better off using an HDMI cable system. It’s ubiquitous, easy to use and will offer great image quality. However, the lack of a locking mechanism in the HDMI port means that at longer distances the cable has chances of getting loose or coming off entirely.

When to use DisplayPort: If you're one of those gamers that have multiple displays daisy chained in a single system or you want to run a really high-resolution on a gigantic monitor, you're better off using DisplayPort. Also, at higher distances, the secure locking mechanism of DisplayPort means that you're sure of the cable staying put. You can use an HDMI cable for this too, but it’s much easier to connect monitors in multiple mini DisplayPorts than connecting them through an HDMI interface.

For more information about this often ignored aspect of PC gaming, be sure to check out the Wikipedia page of the respective standards for all the technical specs.

PC gaming 101: Part 3: Be a Smart Buyer

PC gaming is quite big in India. As games become more intense and compelling, gamers find themselves wanting the latest and greatest hardware to run these games smoothly. That being said, the majority of gamers wanting to build or upgrade their machines don’t have much of a clue, and are often at the mercy of vendors and salesmen, due to which, more often than not, they end up making the wrong decisions. This is an attempt to address this lack of information, and help all PC gamers make the best of their resources. This is PC GAMING 101.

 

 

The “More RAM equals better Graphics card” Myth

An age-old trick of most Indian video card vendors is the whole “it’s got more video memory” trick. Most people don't really understand the specifics of video cards, and end up getting duped by vendors who convince them that a card with more video memory (or video RAM) is better or “superior” to a card with less RAM.

ramNO

First of all, just because a GPU has more video RAM doesn’t make it a better or a faster GPU.

Simply speaking, GPU video memory these days is either DDR2 or DDR3, just like RAM. DDR2 memory is the cheaper of the two. DDR3 is newer and faster.  Vendors usually just mention the amount of video memory on the card, and not what type of memory it is. So, a card with 1.5 GB of DDR3 memory may actually perform better than a card with 2GB of DDR2 memory, despite the latter having “more RAM”.  Knowing the type of memory is thus equally important.

 

 

“Most people are uninformed and salesmen easily dupe them. A salesman once tried convincing me that a card with 2GB of RAM was superior to a card that cost thrice as much but had lesser, but DDR3 RAM! These people are unscrupulous, and take advantage of the average buyer’s ignorance.”

says Kartik Iyer, a PC gamer. Don’t get fooled by vendors who try to sell you cards by telling you that it’s got more RAM.

That being said, if you’re assembling a PC and you want to future-proof it, the rate at which the system requirements of PC games are going higher, cards with 1GB of video RAM or less won't cut it for much longer.  So, for a future-proof PC that'll last you for two or three more years, try getting a card that’s got a video memory of 1GB or more, but be sure to check the type of memory present in it.

It’s not just Nvidia and AMD Radeon

When it comes to graphics card brands, most of us know the two major brands- Nvidia, and AMD Radeon. So it’s just a matter of which one of these to choose, right?

It’s not that simple.

Nvidia and AMD Radeon do manufacture cards themselves, but there are also many other manufacturers who simply use the card designs, slap their own names on them and sell them. Thus there are two main categories of cards- Reference and Non Reference.

A reference style GPU usually means that the card is presented as the GPU maker had intended (Nvidia and AMD). this includes everything from the PCB, layout of the components and the heatsink/fan.

A non-reference card is when the card manufacturers (like Gigabyte, Asus, MSI, Sapphire and Zotac, to name a few)  make changes that deviate from the original design. These changes can be something like a better heatsink/fan design, overclocking, changes to the PCB or any other changes that they see fit to make.

Reference versus Non-Reference cards

Reference cards are always in-line with the specifications provided by the main companies, and have a certain level of quality about them. However, manufacturers often prefer to tweak the stock settings like the processor speeds, cooling systems etc. to differentiate themselves from the market. Hence for a particular model number you might find various different "editions", like "gaming edition" or "extreme edition" and so on, which offer some level of customizability in terms of things like Overclocking and Cooling. However, although these non reference models offer some improvement over the basic reference design, some companies often use cheap components and manufacturing methods to keep costs low. Rishi Alwani, PC gamer and occasional game reviewer says:

“Don’t buy Zotac! The prices are low but there’s no real guarantee that your card will run for long. I’ve used Zotac cards in PC builds before and I ended up replacing them due to faults and malfunctions, so be careful while getting low-cost cards!”

All in all, you'll need to do quite a bit of research and comparison to get the best card, and the best deal.

Research- make an informed choice

Research is essential before buying graphics cards, as y’all already know. The problem lies in the fact that there are so many sites on the internet that offer conflicting, confusing and even sometimes misleading information. Here’s a list of websites you should go to for your researching needs:

1. Anandtech: A website dedicated to tech reviews, both hardware and software. Great for reading reviews.

2. GPUreview: Dedicated to graphics cards. Offers a neat comparison tool that allows you to compare two cards side by side, and look at each individual specification.

3. HardOCP: Great website that offers reviews and news about the latest computer hardware.

 

Think of the System as a whole

When buying a card, make sure that the card you buy is right for your system.  A low powered GPU might act as a bottleneck for a system with a powerful CPU, and a high-powered GPU on a lower end system might be a waste of money. Jayesh M, a PC enthusiast says:

“Make sure your system is correct. If you buy a GTX 660 but got a powerful i7 processor, you are wasting your system potential, or vice versa.”

While buying a card, it’s also prudent to know the resolution of your display. If you have a display that’s 1920X1080 aka an HD display, spending more than 20k on graphics equipment is a waste of money, says Rishi.

Now that we’ve gone through what’s needed to buy smart, we will go into the details of some often ignored but important things- starting with Display technology. Stay tuned folks!

PC Gaming 101: Part 1: Initial Configuration and the PSU

PC gaming is quite big in India. As games become more intense and compelling, gamers find themselves wanting the latest and greatest hardware to run these games smoothly. That being said, the majority of gamers wanting to build or upgrade their machines don’t have much of a clue, and are often at the mercy of vendors and salesmen, due to which, more often than not, they end up making the wrong decisions. This is an attempt to address this lack of information, and help all PC gamers make the best of their resources. This is PC GAMING 101.

 

 

If you’re a PC gamer, you’ve most probably heard the term “GPU”. Commonly called “graphics cards” here in India, every gamer wants the best GPU they can get. But, with a lot of buzzwords and marketing fluff being thrown about these days, it’s easy to get totally confused and lose your way. Here are the things a person wanting to buy a GPU must remember to make the best and most informed choice:

 

Know your PC Configuration

When looking to upgrade your PC, it is absolutely essential to know the specifications and configuration of your PC.  This is a seemingly obvious but often overlooked step.  With some amount of looking up, one should be able to find out specifications like the model number of the motherboard, amount and type of RAM, existing cooling system (cooling fans etc) and the CPU cabinet. However, one of the most important things that must not be overlooked is the Power Supply Unit, or PSU.

The PSU

The power supply unit is the component of the PC which converts the power from the outlet, into usable power that drives all the different parts inside the computer. From a PC gamer’s point of view, what’s important is knowing the power rating. The power rating is mentioned on the PSU itself, and one just needs to open the CPU cabinet to take a look at it. The PSU looks like this:

psu_1280

 

And the voltage ratings can be found on the sticker on one side:

psuSticker

 

The different columns under “voltage” are called “rails”, and one must note the power output for each rail along with the maximum power output. Why this matters is, GPUs generally have certain voltage requirements, which if aren't met, might cause serious issues, malfunctioning or may lead to the system not working at all. “Knowing the power supply requirements is essential. I had my graphics card lying idle for a year because it needed a better power supply” says Kartik Iyer, an avid PC gamer.

So be sure to check if the wattage of your PSU matches the recommended PSU wattage specified by the vendor. (Note: the recommended wattage is for the entire system and not just the GPU, so be sure to calculate the power requirement of the whole system) .

Here’s a handy tool that will help you to calculate the total power requirements for your system.

Stay tuned for part 2, where we'll talk about getting the right GPU for your usage.
