How Do I Choose the Best Dual Video Card?

VGA video capture card is a kind of hardware that collects VGA data. VGA signal transmission is a hot spot in video signal transmission. In order to display high-quality images, traditional AV signal transmission methods can no longer meet the requirements. The information processed by the video card is ultimately It must be output to the monitor. The output interface of the graphics card is the bridge between the computer and the monitor. It is responsible for outputting the corresponding image signals to the monitor. Although the LCD can directly receive digital signals, many low-end products use the VGA interface in order to match the VGA interface graphics card. In the acquisition, transmission, and processing of analog and digital signals, in addition to the more common interfaces such as USB, they are VGA interface, DVI interface, and HDMI component. These interfaces are especially VGA interface and VGA signal acquisition and capture equipment in video capture cards. A common video capture card using a VGA interface is a VGA video capture card.

VGA video capture card works by RGB

1. Support multiple cards in one machine, using the highest-grade VGA capture chip;

2.Support VGA display mode: 640x480, 800x600, 1024x768, 1152x864, 1280x720, 1280x800, 1280x960, 1280x1024, 1440x900, 1600x1200, 1680x1050, 1920x1080, 1920x1440;

3. PCI-E 1x interface, a single card can simultaneously acquire 1 VGA signal, 2 video signals, 1 channel

1. The picture size can be scaled with high quality.

2. Automatically remove black edges of VGA.

3.

With the wide application of VGA video capture cards, how to choose VGA products has become a concern for everyone. Because VGA video capture cards belong to higher-end professional products and have few people in contact, there are many difficulties in product selection, making The user does not know how to choose, the following briefly describes the choice of VGA capture card from several aspects.

1.Is it a self-developed product?

Before choosing a VGA video capture card product, we first need to understand the general situation of the manufacturer, such as whether the company develops its own products and has a durable supply capacity. Why do you say that? The key issue is VGA video capture. The card's R & D difficulty and technological content are relatively high. There are also some professional application problems that customers need to solve during the application process. This characteristic determines that there must be good technical services to guarantee and must Have the ability to solve problems quickly and accurately, so it must be required that the card is best developed independently to ensure the normal use of customers.

Product performance

Image quality. This is relatively simple. It is enough for the manufacturer to send an evaluation description or a picture of the product. If it is close to the capture card production company or in the same city, the customer can go to the factory or the manufacturer to test.

Collection card point frequency, this can be seen in the product profile, the higher the value of the collection
