[0025] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0026] Please see Figure 1 and Figure 2 ,in, Figure 1 This is a schematic diagram of the connection structure between the video P2P signal tester and the P2P screen under test provided by this utility model.

The host 10 supports the P2P protocol and is connected to the power supply 20. The first P2P adapter board 30 connects the host 10 and the P2P screen under test 200, and is used to convert the interface wiring sequence of the host 10 to the hardware interface wiring sequence of various models of the P2P screen under test 200. The second P2P adapter board 40 connects the host 10 and the motherboard under test 300, and is used to convert the hardware interface wiring sequence of various types of the motherboard under test 300 to the interface wiring sequence of the host 10. The first screen cable 50 connects the host 10 and the first P2P adapter board 30; the first P2P connection cable 60 connects the first P2P adapter board 30 to the P2P screen 200 under test; the second screen cable 70 connects the host 10 and the second P2P adapter board 40; and the second P2P connection cable 80 connects the second P2P adapter board 40 to the P2P motherboard 300 under test. The HDMI cable 90 is used to connect the host 10 to an external display.
[0027] It is understood that in some other embodiments, the video P2P signal tester may be configured not to include the first P2P adapter board, the first screen cable, and the first P2P connection cable. In some other embodiments, the video P2P signal tester may be configured not to include the second P2P adapter board, the second screen cable, and the second P2P connection cable.
[0028] In some embodiments, the power supply 20 has a built-in power cord for providing 12V power to the host 10.
[0029] The host 10 can be an EXV2051 host, supporting the P2P protocol, used to test the P2P screen 200 under test and the motherboard 300 under test. When the host 10 is connected to the P2P screen 200 under test, it outputs a corresponding P2P signal to the screen 200 to display various test images such as solid color, color bars, and grayscale. Based on the display results of the screen 200 under test, its quality and display effect can be determined. When the host 10 is connected to the motherboard 300 under test, the motherboard 300 outputs a P2P signal to the host 10, and the host 10 displays the image through its built-in display panel or an external monitor. Based on the display results, it can be determined whether the motherboard 300 under test is malfunctioning.
[0030] Understandably, the external monitor can be an LCD screen or an OLED screen.
[0031] Please see Figure 3 and Figure 4 , Figure 3 for Figure 1 The diagram shown illustrates the connection between the host computer and the P2P screen under test. Figure 4 for Figure 1 The diagram shows the connection between the host and the P2P motherboard under test. In this embodiment, the host 10 includes a casing, a circuit board, a P2P signal output interface 13, a P2P signal input interface 14, an HDMI signal output interface 15, a Link interface, a USB-A interface, a power interface, an LCD panel 17, and buttons.

[0032] The circuit board includes a signal generation circuit 121, a signal switching circuit 122 connected to the signal generation circuit 121, and a signal parameter adjustment circuit 123. The signal generation circuit 121 outputs a P2P signal to the P2P signal output interface 13. The P2P signal output interface 13 is connected to the first P2P adapter board 30 to enable the P2P screen under test 200 to display a test image. P2P signals include various types, such as CEDS, CSPI, ISP, EPI, etc., and also include various mode parameters. Based on mode parameter classification, there are over 100 types of P2P signals. The signal generation circuit 121 supports outputting multiple P2P signals and can support various resolutions and image signal types with strong compatibility. The signal switching circuit 122 switches the type of P2P signal output by the signal generation circuit 121, and the signal parameter adjustment circuit 123 adjusts the parameters of the P2P signal output by the signal generation circuit 121. According to the types of P2P signals supported by the P2P screen under test 200, the user inputs a user command to the host 10 through the button, controls the signal switching circuit 122 and the signal parameter adjustment circuit 123, so that the signal generating circuit 121 outputs the P2P signals supported by the P2P screen under test 200.
[0033] The circuit board includes a signal acquisition circuit 125, a display parameter adjustment circuit 126, and a signal conversion circuit 127. The second P2P adapter board 40 is connected to the P2P signal input interface 14. The signal acquisition circuit 125 is also connected to the P2P signal input interface 14, acquiring the P2P signal output from the P2P motherboard under test 300. The signal conversion circuit 127 is connected to the signal acquisition circuit 125, converting the P2P signal output from the P2P motherboard under test into a display signal, which is then displayed on the LCD panel 17 or an external monitor. The display parameter adjustment circuit 126 adjusts the display parameters of the display signal. The user, based on the type of P2P signal output from the motherboard under test 300, inputs a user command to the host 10 via the buttons, controlling the signal acquisition circuit 125 and the display parameter adjustment circuit 126. This causes the signal conversion circuit 127 to encode and decode the P2P signal output from the motherboard under test 300 based on the corresponding communication protocol, displaying it on the LCD panel 17 or an external monitor.
[0034] The P2P signal output interface 13 has a first wiring sequence. The first P2P adapter board 30 includes a first interface 31 and a second interface 32 connected together. The first interface 31 has the first wiring sequence and is connected to the P2P signal output interface 13. The second interface 32 has a second wiring sequence and is used to connect to the P2P screen 200 under test, which has the second wiring sequence.
[0035] The P2P signal input interface 14 has a third wiring sequence. The second P2P adapter board 40 includes a third interface 43 and a fourth interface 44 connected together. The third interface 43 has the third wiring sequence and is connected to the P2P signal input interface 14. The fourth interface 44 has a fourth wiring sequence and is used to connect to the P2P motherboard 300 under test, which has the fourth wiring sequence.
[0036] It is understood that the P2P screen 200 and the P2P motherboard 300 under test, which support different P2P signals, have different wiring sequences. By selecting the first P2P adapter board 30 and the second P2P adapter board 40 with different wiring sequences, the video P2P signal tester 100 can test various P2P screens 200 and P2P motherboards 300 under test.

The 60-pin P2P wiring interface is connected to the 51-pin wiring interface, and the 68-pin P2P wiring interface is connected to the 51-pin wiring interface.
[0038] The HDMI signal output interface 15 is used to connect to an external monitor, and the Link interface can be used for function expansion and customer customization needs. The USB-A interface can support software upgrades, and firmware upgrades can also be performed when new requirements arise, thus maintaining optimal compatibility. The power interface is used to connect to the power supply 20. The buttons include an up button, a down button, an confirm button, and a reset button, used to input user commands to the host 10 to select the functions of the P2P screen 200 under test and the P2P motherboard 300 under test, and to select firmware upgrades.
[0039] In some embodiments, the up key can be configured such that a short press moves the cursor up, and a long press for 1 second moves the cursor left; the down key can be configured such that a short press moves the cursor down, and a long press for 1 second moves the cursor right.
