Errors that occur due to video cards are known as visual artifacts. Most of the time, such artifacts are caused due to some hardware or software problem. So, one should keep updating their system hardware after certain period of time in order to avoid video card related problems.

Make sure that all the fans are working and especially the fan above video card is effective as overheating of video card may be the very first reason of such fault. Rise and fall of the temperature of video card depends upon the kind of program you are running. Running 2D program will keep the temperature of video card cool while running 3D program will definitely raise its temperature.There is one silicon chip present on the video card that runs slow due to increase in temperature. You can check this problem by using your system with CPU cabinet open and if by doing so artifacts go away, it means overheating of video card was the main reason. In order to lower the temperature of video card, you can under lock the video card. This will reduce clock rates of video card resulting in lowering the temperature.

Problem in video card can occur due to three sources. First is the Video RAM present in the video card, second is GPU which is a chip on the video and the last one is bus interface whose main work is to transfer data between video card and motherboard.If you want to play high graphics game on your computer, you have to start upgrading the system by upgrading the video card. There are some issues that may come while installing video card. It may happen that you find difficulty in replacing built-in video card with PCI express video card. In such case, check out the manufacturer details whether it is allowing replacement of original video card or not. You can also disable on-board video card from BIOS. Also check whether your motherboard has a jumper or not. Jumper helps in switching between built in and add-on video cards.

One may find difficulty in changing colour depth and resolution of video card. Solution for this problem is quite simple. You have to check whether your video card is being identified in Windows or not. If it is identified then you can update your video card from the manufacturer’s website. Sometime it may happen that your display works only in DOS or at booting time but not in windows. Such problem occurs only when your video drivers are either corrupted or expired. To fix this issue, enter into safe mode by pressing F8 and install proper driver. Overclocking video card may increase the speed of video card. To fix this issue, go in Safe Mode and use tools to restore the normal default speed of video card. If you are unable to change OpenGL or Direct 3D settings of video card then try to install video card vendor drivers as they comes with 3D and other advance options that will improve the video quality for sure.

Most of the computer operation requires video card in some proportion and any kind of problem will affect your computer system directly. So it’s better to troubleshoot video card related problem as soon as possible.

The name of this article says it all. You have to enter on the Amazon site and while you are there, check the Search button, where you will write “AGP video cards”. You will find many results in the search results list, but you will take in consideration the first one.

Ok, after you have reached to this point, it means that you are at the same level where I am right now. And I read about the EVGA GeForce DDR2 AGP graphics card by EVGA. The price of this card is as you can see it as well, of $45.

But let’s see the technical details of this AGP video card. If you want to see some other AGP cards, check this article, where I presented another one. The technical details of this card start with this description: AGP 8x. The video card has 6200 LE, that function at a speed of 300 MHz. You cannot compare this speed to the speed of a processor. This is the speed of the images that are presented on the screen. The DDR2 memory has 512 MB. This is good, but it can be improved. Now, there are video cards with larger amounts of video memory. The card supports the Microsoft DirectX 9.0 driver. Open GL 2.0 is another feature that is supported by this video card. The weight of the video card makes it perfect for any laptop, only 12 ounces. The shipping weight would be of only 1 pound, because it will be attached the whole package that is supposed to protect the video card during transportation. 71 customers consider that this video card is worth 4 stars out of 5.

The GeForce chipset means that this is a powerful video card and you can use it without a problem on a gaming computer. The product comes with one year warranty, but you can get also the second year of warranty for free, if after you buy the video card, you register it on the evga.com site within 30 days from its purchase. You all know that GeForce is a brand of NVIDIA, so I guess that you can tell by now that this AGP video card that is available on Amazon and not only, benefits of the NVIDIA architecture, which is unified, as we can see on the Amazon site, in the Product Description section. This is not all, you will benefit of a TV encoder, that is great for those who are addicted to TV shows. And when they are not seen on YouTube, this encoder is the solution. The effective rate of 1064 MHz makes this product a perfect gift for a person that you know he has a computer, but with a poor video card. And for 45 dollars, I think it is more than a bargain.

AGP stands for Accelerated Graphics Port and it is a standard in the creation of the video cards or graphics cards. In my quest of finding an AGP TV video card, I have found the Visiontek 400518 Radeon HD 3650 graphics card, that allows the user to connect the computer to a TV.

Let’s see what are the technical specifications of thisAGP video card. The interface type is obviously AGP, while the interface speed is of 8x. The connectors that allows the actual connection to a TV are in order: the VGA port, the S-Video port and the DVI port. The graphics card supports multiple monitors. The chipset is created by ATI and it is a Radeon model. The type of the graphics card is mainstream. This is a type that is not only used when it comes to computers, but to video cards as well.

The maximum number of the monitors included is of 2. In my opinion, it is enough. The user needs to be connected on both devices at the same time and I think that 2 is the maximum number for the human eyes as well. Nevertheless, I have found central units that were connected to 3 monitors at the same time. The maximum resolution offered by this video card is of 2560x1600. This is a digital resolution and I guess that you imagined it by now that this type of resolution can be seen only on a TV, not on a computer. The video memory type is of DDR2 and the whole amount of memory is of 128 bits. The supported APIs are represented in fact by only one: DirectX 10.1. The video output of the video card uses the DVI standard. The minimum PSU wattage requirement is of 300 watts.

Regarding video cards, we have plenty of articles on our site. You can read for example, this article, where some of the best graphics cards in the world are described. This article is about the NVIDIA video cards. This manufacturer is always taken into consideration when you build your own computer. Nevertheless, the Visiontek video card, that I presented in this article, should be an option, because you have seen that this graphics card has a lot of options. Those interested in playing games on their computers, more than just watching movies or seeing how the photos appear on the screen, should get an NVIDIA card, because these ones are the best for these tasks. The rest of the cards available on market are good for almost any activity, except the gaming one. The games are perfectly seen on an interface based on the NVIDIA technologies.

In February 2008, NVIDIA announced that they will buy the Ageia technologies. This last company is or better said was at that time the world’s leader in gaming physics. I guess that now you see why the giant in the visual computing technologies world aquired this other leader. The Ageia’s world famous software is PhysX software. The standards created by this company in the gaming industry have been adopted by many game platforms, some of them being created for devices like: the Sony PlayStation 3 device, Nintendo Wii and Microsoft’s XBOX 360.

So, what do the Ageia PhysX video cards bring in front of the eyes of an user, compared to the rest of the video cards, created by NVIDIA and not only by this company? As you can read on the manufacturer’s site, there are a lot of advantages for the Ageia’s users. The video cards that have the PhysX factor included (this is like the X factor, only for gaming), brings more realism to the users who were accustomed to a certain interface. This interface will seem new to them, they will start seeing other possibilities in the games that they play and overall, they will have the impression that the characters of the games are in the room with them.

Just try an NVIDIA GeForce video card, that has the Ageia standard incorporated and you will actually feel the reactive debris that passes next to your head, you will feel the vibrations of the Earth, when the soldiers come into your bedroom, you will see some explosions that will make you put your hands at your ears, even though the sound will not be high (unless you set it this way), and you will feel and even smell the water. These are reactions offered by your brain, because the experience is so realistic. There are some featured demos and videos on the manufacturer’s site, that I invite you to check out. Also, I invite you to read the articles on our site regarding the video cards, because they contain some additional information, that I cannot mention in every article.

Some of the games are taken into consideration and the manufacturer explains what are the possible reactions of your eyes and of your brain to them. For example, in the case of Batman: Arkham Asylum, you will experience a world full of life. The smoke and the fog will seem to invade your bedroom, the characters will enter the environment in which you also are, the objects react to explosion in a very interesting way and in general all the items create a unique atmosphere.

There is not a person alive that has at least the slightest experience with computers that hasn't heard of Nvidia. Of course, a not so experienced person might say that Nvidia produces that stuff that makes new games run on the PC. That's close, but no dice.

Nvidia is a world leading graphics card manufacturer and it's mostly renowned for that. When making your very own computer configuration, you don't actually think about Nvidia until you get to the graphics processor. But they do more than just that. They also have things like chipsets and media player software.

Due to the launch of the long awaited Duke Nukem game, Nvidia chose to show their support for it by using the Duke's image on their website, when presenting the new GTX 560 video card. Computer games have progressed so much in graphics technology that most serious gamers need to buy themselves a new card every day to keep up with the times. I'm just kidding, although graphics technology nowadays does change really fast. The 560 tries to make the most out of today's possibilities by trying to appeal to gamers with various features, like employing the CUDA technology. This CUDA is their parallel programming architecture and it uses the resources of the GPU to help the central processing unit in different computations. Its benefits don't just stop at gaming; it also gets the job done in processing videos and images or simulating fluid dynamics. Another interesting piece of technology used by this model of video card is the Nvidia 3D Vision, which combines the GPU, specific software, glasses and specific displays to give you a 3D experience similar to the one at the movies.

The 3D Vision can also be used in two scenarios: for home use and for professionals. Home use refers to the games you play at home, or the movies you watch on your PC. Professional use is designed mostly for people who work with CAD or 3D video editing tools. As you may or may not already know, some modern Nvidia video cards can take full advantage of the SLI technology, on SLI compatible motherboards, of course. This actually allows you to combine multiple graphics cards to increase performance, kind of like ATi's Crossfire. You might think that SLI can combine only two graphics card, but that couldn't be more wrong. You can combine 3 GPUs and give them different roles, like use one card for rendering game graphics and reserve another for all PhysX calculations, thus speeding up games.

You should never buy a video card just according to what it says about it on their website. Feel free to check out forums where a specific card is mentioned so you can learn from the past experience of others. Don't be ashamed to ask any question there either. You just don't want to spend a lot of money on something that goes bad after 6 months.
