How to choose a graphics card for point-to-point splicing projects

At present, there is an increasing demand for point-to-point super-resolution in LCD splicing wall projects, such as the need to display rich detailed content in big data, and the need to display multiple web pages, videos, and images non-destructive on each LCD unit through a computer for exhibition display. Regarding the advantages of point-to-point splicing projects, we will introduce them in other chapters. This article focuses on the configuration of graphics cards.

To build a set of point-to-point super-resolution splicing walls, in addition to the TK-GT series professional point-to-point splicing processors, it also requires the cooperation of professional graphics cards. Many users often fall into a misconception when configuring professional graphics cards, thinking that the more expensive the graphics card, the better, regardless of the type of graphics card.

Simply put, regarding computer configuration, we generally recommend that users have a minimum configuration of an i7 computer. In addition to graphics cards, we generally recommend that users consult computer vendors to recommend configurations with better overall performance, such as hard drives, CPUs, and memory. If the user is using it to display 3D animations, interactivity, and ultra high resolution videos, it is recommended to have a higher configuration on the computer.

Next, let's focus on the graphics card. Install a set of point-to-point ultra high resolution splicing walls, with the core components being computer graphics cards in addition to the point-to-point splicing processor. For computer graphics cards used for point-to-point splicing, the more expensive the better, but the more suitable a professional graphics card is. Otherwise, it may cause the problem of inability to set up point-to-point splicing. Please be sure to configure according to the model provided by the manufacturer or supplier of the point-to-point processor.

Firstly, if it is a small-scale splicing project, such as some 10-20 point-to-point splicing projects, most (not all) can be completed with a Nvidia Quadro series 4-head graphics card, such as commonly used A4000, A2000, T1000, T600, P1000, P2200, P4000, M2000, M4000, M5000, etc

If the user's splicing mode or scale cannot be achieved using Nvidia Quadro series 4-head graphics cards and requires 5 or 6 graphics card output ports, it is recommended to use AMD series professional graphics cards, such as W5700, W6800, Radeon Pro VII, WX9100, etc.

For splicing modes that cannot be completed by 6-head graphics cards, we need to consider using two or more Nvidia Quadro series graphics cards with synchronization functions, such as RTX A4000, RTX A5000, RTX A6000, RTX 4000, RTX 5000, RTX 6000, RTX 8000, P4000, P5000, P6000, etc

In addition, professional graphics card output interfaces are either DP or mini DP, and the TK-GT series point-to-point splicer input interface also supports DP. Using a DP cable (if the graphics card is a mini DP, please use a mini DP to large DP cable) to connect the graphics card and the point-to-point splicing processor can ensure completely lossless and stable signal transmission. However, using DP to HDMI signals may result in the inability to transmit ultra clear signals and increase stability risks.

Due to the fact that regular DP lines are generally short, ranging from one meter to five meters, when building point-to-point splicing walls, it is important to place the computer and the point-to-point splicer in the same position to avoid being too far away and unable to find the appropriate length of DP lines.
