[0024] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.
[0025] Figure 1 This is a schematic diagram of a device for adjusting display resolution provided in an embodiment of this disclosure. Figure 1 As shown, the device includes an HDMI cable and a controller. The HDMI cable includes HDMI OUT and HDMI IN, with the HDMI interface on the terminal side outputting the signal. A controller is added at the HDMI interface on the display side. This controller contains a signal processing chip, a physical switch, a microcontroller (MCU), and an EDID storage chip. When a certain display resolution needs to be tested, the controller switch is pressed to switch the resolution, and then the determined EDID signal after the switch is output to the display to display the target image at the switched resolution.
[0026] Specifically, this embodiment provides a device for adjusting display resolution, comprising: an HDMI cable and a controller; wherein the input interface of the HDMI cable is connected to a zero terminal, the output interface of the HDMI cable is connected to the input of the controller, and the output of the controller is connected to a display; the controller includes a signal processing chip, a switch controller, an EDID storage chip, and a microcontroller; wherein the signal processing chip has multiple pre-programmed EDID data, which selects the currently active EDID data through the switch controller and sends the currently active EDID data to the display, so that the display displays the target image at the resolution corresponding to the currently active EDID data. The EDID storage chip pre-stores EDID data of different resolutions and has EDID reading, EDID storage, and EDID pass-through functions; the microcontroller controls the EDID storage chip to switch between the EDID reading, EDID storage, and EDID pass-through functions.
[0027] In this embodiment, the microcontroller is used to control the chip switching logic. The zero terminal is connected to the HDMI cable for image acquisition. At the main signal processing chip, the switch controller is used to adjust the resolution to be displayed. That is, the EDID main signal processing chip has a variety of pre-programmed EDID data built in, such as 1080p@60Hz / 4K@30Hz, etc. The switch controller selects the currently active EDID and outputs it to the display. The screen displays the target image at the adjusted resolution.
[0028] EDID storage chip: This chip pre-stores EDID data at different resolutions (e.g., 1080p, 2k, 4k). Specifically, for EDID storage chips, any chip on the market with EDID storage functionality can be selected. For example, the 2LT6911C can be chosen. The 2LT6911C itself provides EDID support in the following aspects: EDID Reading: The LT6911C reads the monitor's EDID data through the EDID interface of the HDMI receiver (usually an I2C bus).
[0029] EDID storage: The chip has a built-in EDID cache that can store up to 3 EDID blocks (128 bytes each).
[0030] EDID pass-through: Supports passing the original EDID data through to the MIPIDSI / DP output terminal, or sending it after modification.
[0031] Switch controller triggers switching: The MCU configuration is changed by a physical switch, and the corresponding EDID data is selected and sent to the display.
[0032] It should be noted that the display resolution adjustment device in this embodiment also includes a power management module, which can ensure a stable power supply to the adapter cable. Specifically, it can be powered by a USB interface.
[0033] As shown in the figure, when connecting a 4K or 8K monitor, different resolutions are switched via the controller's power button for display verification during resolution compatibility testing. At this time, the switched resolution is less than or equal to 8K, meaning that all negotiable monitor resolutions up to 8K can be set.
[0034] In one embodiment, such as Figure 2 As shown, the switch controller is equipped with buttons; When the button is triggered, the signal processing chip generates currently active EDID data based on the button operation event and sends the currently active EDID data to the display; wherein the currently active EDID data is arranged in order from lowest to highest or highest to lowest.
[0035] In this embodiment, a button or touch button is provided on the switch controller. Pressing it once triggers an EDID to be displayed on the display. The EDIDs generated by the button can be sorted from lowest to highest or from highest to lowest.
[0036] In one embodiment, such as Figure 3 As shown, the switch controller is also equipped with an LCD screen; When a button is pressed, the LCD screen displays EDID data generated by the signal processing chip based on the button operation event.
[0037] In this embodiment, the controller is equipped with an LCD screen. Pressing a button once will display the currently set EDID. The display order is the same as the sorting method for EDID generated by the button.

Figure 4 As shown, the method includes: Step 401: Select the currently active EDID data via the switch controller; In this step, the signal processing chip, also called the main chip, selects the currently active EDID data through the switch controller connected to it.
[0039] In one embodiment, selecting the currently active EDID data via the switch controller includes: Acquire button operation events on the switch controller; The currently active EDID data is generated based on the key operation event, and the currently active EDID data is sent to the display; wherein the currently active EDID data is arranged in order from lowest to highest or highest to lowest.
[0040] In this embodiment, the signal processing chip first needs to acquire the button operation events on the switch controller, generate the currently effective EDID data based on the button operation events on the switch controller, and send the currently effective EDID data to the display.
[0041] Step 402: Send the currently active EDID data to the display; Step 403: Instruct the display to display the target image at the resolution corresponding to the currently effective EDID data.
[0042] In this step, after the signal processing chip sends the currently effective EDID data to the display, it instructs the display to show the target image according to the resolution corresponding to the currently effective EDID data.
[0043] Optionally, the method further includes: Send display commands to the switch controller; The display instruction is used to instruct the switch controller to display the currently active EDID data on its display screen according to preset rules.
[0044] In this embodiment, after the switch controller receives the display command sent by the signal processing chip, the switch controller will display the currently effective EDID data in order from lowest to highest or highest to lowest.
[0045] The present disclosure provides a method for adjusting display resolution, which can solve the problem of cumbersome operations such as frequently changing monitors and connecting cables in monitor compatibility testing, thereby reducing the testing workload and improving testing efficiency.
