一種輸出介面資訊之回報方法及其相關電腦系統，尤指一種可於電腦作業系統中正確地顯示輸出介面資訊的輸出介面資訊之回報方法及其相關電腦系統。A method for returning output interface information and related computer systems, and more particularly to a method for returning output interface information that can correctly display output interface information in a computer operating system and related computer systems.
隨著科技的發展與進步，各式電子產品及裝置已成為使用者生活中不可或缺的一部分，如可攜式電子裝置、個人電腦等，各種電子裝置的製造商為了提供使用者更高品質及舒適的使用環境，電子產品的周邊設備的規格要求也越來越高，舉例來說，通用序列匯流排（Universal Serial Bus，USB）的規格自舊有的USB1.1、USB2.0演進為傳輸速度較快的USB3.0，或者視訊介面由視訊圖形陣列（Video Graphics Array，VGA）演進為高畫質多媒體介面（High Definition Multimedia Interface，HDMI）等。為了滿足使用舊有周邊設備的使用者有些電腦視訊晶片組中仍保留舊有的輸出介面，如VGA介面以提供使用者使用VGA螢幕。With the development and advancement of technology, various electronic products and devices have become an indispensable part of the user's life, such as portable electronic devices, personal computers, etc., manufacturers of various electronic devices in order to provide users with higher quality And the comfortable use environment, the specifications of the peripheral devices of electronic products are also getting higher and higher. For example, the specifications of the Universal Serial Bus (USB) have evolved from the old USB1.1 and USB2.0 to USB3.0 with fast transmission speed, or video interface evolved from Video Graphics Array (VGA) to High Definition Multimedia Interface (HDMI). In order to satisfy the use of old peripheral devices, some computer video chipsets still retain the old output interface, such as the VGA interface, to provide users with a VGA screen.
但是新式電腦視訊晶片組的視訊輸出規格通常並未設有VGA輸出介面。因此製造商在設計時會於視訊晶片組之後另增加一個訊號轉換晶片來將視訊訊號轉換成顯示螢幕所支援的訊號類型。然而，作業系統通常係透過晶片組驅動軟體去取得視訊晶片組之輸出介面類型並將之判斷為顯示螢幕之視訊介面資訊，如此一來，將會導致誤判的情形。例如，若視訊晶片組並未配置有VGA螢幕的輸出介面而於視訊晶片組後端增加訊號轉換晶片來將視訊訊號轉換成VGA訊號。當使用者將VGA螢幕連接至電腦裝置之後，作業系統透過驅動程式僅能得知視訊晶片組的輸出介面類型，而無法得知訊號轉換晶片的輸出介面。因此導致使用者於使用VGA螢幕時，電腦系統軟體會因為偵測不到正確的視訊介面資訊而顯示錯誤，進而影響使用者使用時的便利性。However, the video output specifications of the new computer video chipset usually do not have a VGA output interface. Therefore, the manufacturer will add a signal conversion chip after the video chipset to convert the video signal into the signal type supported by the display screen. However, the operating system usually uses the chipset driver software to obtain the output interface type of the video chipset and judges it as the video interface information of the display screen, which may lead to misjudgment. For example, if the video chipset is not equipped with an output interface of the VGA screen, a signal conversion chip is added to the back end of the video chipset to convert the video signal into a VGA signal. After the user connects the VGA screen to the computer device, the operating system can only know the output interface type of the video chipset through the driver, and cannot know the output interface of the signal conversion chip. Therefore, when the user uses the VGA screen, the computer system software may display an error because the correct video interface information is not detected, thereby affecting the convenience of the user.
因此，如何提供一種輸出介面資訊的回報方法，使得電腦作業系統可正確地取得並顯示輸出介面資訊的機制，也就成為業界所努力的目標之一。Therefore, how to provide a means of returning output interface information, so that the computer operating system can correctly obtain and display the mechanism of the output interface information, has become one of the goals of the industry.
因此，本發明之主要目的即在於提供一種輸出介面資訊的回報方法及其相關電腦系統，以正確地偵測並顯示輸出介面資訊。Therefore, the main object of the present invention is to provide a method for reporting output interface information and related computer systems to correctly detect and display output interface information.
本發明揭露一種輸出介面資訊之回報方法，包含有利用一基本輸入輸出系統偵測並確認有關於一顯示裝置之一視訊介面資訊；該基本輸入輸出系統透過一管理介面將該視訊介面資訊回報至一作業系統；以及該作業系統控制該顯示裝置顯示該視訊介面資訊。The present invention discloses a method for reporting the output interface information, including detecting and confirming a video interface information of a display device by using a basic input/output system; the basic input/output system returns the video interface information to the management interface through a management interface An operating system; and the operating system controls the display device to display the video interface information.
本發明另揭露一種電腦系統，包含有一處理器；以及一儲存裝置，儲存一程式碼，該程式碼指示該處理器執行一種輸出介面資訊之回報方法，該輸出介面資訊之回報方法包含有利用一基本輸入輸出系統偵測並確認有關於一顯示裝置之一視訊介面資訊；該基本輸入輸出系統透過一管理介面將該視訊介面資訊回報至一作業系統；以及該作業系統控制該顯示裝置顯示該視訊介面資訊。The present invention further discloses a computer system including a processor; and a storage device for storing a code indicating that the processor performs a return method for outputting interface information, and the method for returning the output interface information includes utilizing a The basic input/output system detects and confirms information about a video interface of a display device; the basic input/output system reports the video interface information to an operating system through a management interface; and the operating system controls the display device to display the video information Interface information.
於視訊晶片組後端增加訊號轉換晶片來進行視訊訊號轉換後，由於每種電腦裝置的訊號轉接晶片末端的介面不同，作業系統往往無法正確地取得顯示裝置的視訊介面資訊。舉例來說，當使用者將VGA螢幕連接至電腦裝置，然而電腦的視訊晶片組並未包含有VGA螢幕的輸出介面，作業系統透過驅動程式僅能得知視訊晶片組的輸出介面類型而無法得知訊號轉換晶片的輸出介面，進而造成電腦系統無法正確地顯示其顯示裝置的視訊介面資訊。為此，本發明實施例提供一種輸出介面資訊的回報方法，利用基本輸入輸出系統（Basic Input/Output System，BIOS）及管理介面來偵測並確認視訊介面資訊，以解決電腦系統無法顯示正確的視訊介面資訊的情況發生。After the signal conversion chip is added to the back end of the video chipset for video signal conversion, the operating system often cannot correctly obtain the video interface information of the display device because the interface of the signal transfer chip end of each computer device is different. For example, when the user connects the VGA screen to the computer device, but the video chipset of the computer does not include the output interface of the VGA screen, the operating system can only know the output interface type of the video chipset through the driver. The signal interface converts the output interface of the chip, which in turn causes the computer system to fail to correctly display the video interface information of its display device. To this end, an embodiment of the present invention provides a method for reporting output interface information, and uses a basic input/output system (BIOS) and a management interface to detect and confirm video interface information to solve the problem that the computer system cannot display the correct information. The situation of the video interface information occurs.
請參考第1圖，第1圖為本發明實施例一電腦系統10之示意圖。電腦系統10包含一處理器102及一儲存裝置104。儲存裝置104用來儲存程式碼以供處理器102讀取，程式碼指示處理器102進行相關運作。電腦系統10的作業系統可經由其一應用程式或一驅動程式獲得由BIOS所偵測到有關於顯示裝置的視訊介面資訊，例如對應於顯示裝置之視訊輸入訊號的訊號介面類型，或顯示裝置之視訊輸入訊號的類型等。在一實施例中，視訊輸入訊號的訊號介面類型可為顯示連接埠介面（Display Port，DP）、微型顯示連接埠介面（mini Display Port，mini DP）、高畫質多媒體介面（High Definition Multimedia Interface，HDMI）及數位視訊介面（Digital Visual Interface，DVI）或其他任何視訊介面。Please refer to FIG. 1. FIG. 1 is a schematic diagram of a computer system 10 according to an embodiment of the present invention. The computer system 10 includes a processor 102 and a storage device 104. The storage device 104 is used to store the code for reading by the processor 102, and the code indicates that the processor 102 performs related operations. The operating system of the computer system 10 can obtain information about the video interface of the display device detected by the BIOS, such as the type of the signal interface corresponding to the video input signal of the display device, or the display device, via an application or a driver. The type of video input signal, etc. In an embodiment, the signal interface type of the video input signal can be a display port (DP), a mini display port (mini DP), a high definition multimedia interface (High Definition Multimedia Interface). , HDMI) and Digital Visual Interface (DVI) or any other video interface.
請參考第2圖，第2圖為本發明實施例之一輸出介面資訊之回報流程20之示意圖。輸出介面資訊之回報流程20可被編譯為程式碼而儲存於儲存裝置104中，以指示處理器102執行對應操作。回報流程20包含下列步驟：Please refer to FIG. 2, which is a schematic diagram of a return process 20 for outputting interface information according to an embodiment of the present invention. The return process 20 of the output interface information can be compiled into a code and stored in the storage device 104 to instruct the processor 102 to perform the corresponding operation. The return process 20 includes the following steps:
步驟202：開始。Step 202: Start.
步驟204：利用基本輸入輸出系統偵測並確認有關於顯示裝置之視訊介面資訊。Step 204: Detect and confirm the information about the video interface of the display device by using the basic input/output system.
步驟206：基本輸入輸出系統透過管理介面將視訊介面資訊回報至作業系統。Step 206: The basic input/output system returns the video interface information to the operating system through the management interface.
步驟208：作業系統控制顯示裝置顯示視訊介面資訊。Step 208: The operating system controls the display device to display the video interface information.
步驟210：結束。Step 210: End.
根據輸出介面資訊之回報流程20，於步驟204中，電腦系統10利用每一電腦機種提供的BIOS偵測並確認有關於顯示裝置的視訊介面資訊。於步驟206中，透過管理介面將視訊介面資訊回報至作業系統。舉例來說，管理介面可為微軟視窗作業系統（Windows）提供之一視窗管理介面（Windows Management Interface，WMI），因此，當電腦系統10的BIOS偵測並取得顯示裝置的視訊介面資訊時，即可透過微軟作業系統提供的WMI管理介面，將視訊介面資訊回報至上層的作業系統。最後，於步驟208中，作業系統可控制顯示裝置顯示視訊介面資訊。如此一來，根據本發明的回報流程20於BIOS確認視訊介面資訊後，透過WMI管理介面將可以顯示正確的視訊介面資訊於電腦系統中。如此一來，作業系統便可在視訊晶片組硬體後端進行訊號轉換的情形下，於電腦系統的軟體層面顯示正確的視訊介面資訊。According to the return process 20 of the output interface information, in step 204, the computer system 10 detects and confirms the video interface information about the display device by using the BIOS provided by each computer model. In step 206, the video interface information is reported to the operating system through the management interface. For example, the management interface can provide a Windows Management Interface (WMI) for the Microsoft Windows operating system (Windows). Therefore, when the BIOS of the computer system 10 detects and obtains the video interface information of the display device, The video interface information can be returned to the upper operating system through the WMI management interface provided by Microsoft operating system. Finally, in step 208, the operating system can control the display device to display the video interface information. In this way, the reward process 20 of the present invention can display the correct video interface information in the computer system through the WMI management interface after the BIOS confirms the video interface information. In this way, the operating system can display the correct video interface information on the software level of the computer system in the case of signal conversion at the back end of the video chipset hardware.
舉例來說，若電腦系統10之視訊晶片組的輸出介面為HDMI介面，為了能支援VGA介面之顯示裝置而於視訊晶片組後端增加訊號轉換晶片來將視訊訊號轉換成VGA訊號，以提供至VGA介面之顯示裝置。在此情況下，根據本發明的回報流程20，BIOS可直接偵測顯示裝置以取得有關於顯示裝置之視訊介面資訊（例如，用來傳輸顯示裝置之視訊輸入訊號的介面為VGA介面），並透過WMI管理介面將視訊介面資訊回報至作業系統。如此一來，電腦系統便可透過顯示裝置顯示出視訊介面資訊，讓使用者得知正確的視訊介面資訊（例如，用來傳輸顯示裝置之視訊輸入訊號的介面為VGA介面）。相較之下，若採用傳統的方式，作業系統透過晶片組驅動軟體僅得知視訊晶片組之輸出介面為HDMI介面，因此將會回報顯示出視訊介面為HDMI介面，而讓使用者取得錯誤的資訊。For example, if the output interface of the video chipset of the computer system 10 is an HDMI interface, a signal conversion chip is added to the back end of the video chipset to convert the video signal into a VGA signal in order to support the display device of the VGA interface. VGA interface display device. In this case, according to the reporting process 20 of the present invention, the BIOS can directly detect the display device to obtain information about the video interface of the display device (for example, the interface for transmitting the video input signal of the display device is a VGA interface), and Report the video interface information to the operating system through the WMI management interface. In this way, the computer system can display the video interface information through the display device, so that the user can know the correct video interface information (for example, the interface for transmitting the video input signal of the display device is the VGA interface). In contrast, if the traditional method is used, the operating system only knows that the output interface of the video chipset is the HDMI interface through the chipset driver software, so that the video interface is displayed as the HDMI interface, and the user gets the error. News.
需注意的是，前述實施例係用以說明本發明之精神，本領域具通常知識者當可據以做適當之修飾，而不限於此。舉例來說，根據不同電腦作業系統所內建的組態（embedded configuration），可透過對應於不同電腦裝置的BIOS介面確認輸出端視訊介面資訊。除此之外，本發明的回報方法除了可應用於視訊介面資訊之外，亦可應用於其他輸出介面資訊的回報，且不以此為限，皆屬本發明之範疇。It is to be noted that the foregoing embodiments are intended to illustrate the spirit of the invention, and those of ordinary skill in the art may be modified as appropriate, and are not limited thereto. For example, according to the built-in configuration of different computer operating systems, the output video interface information can be confirmed through the BIOS interface corresponding to different computer devices. In addition, the reward method of the present invention can be applied to other output interface information in addition to the information of the video interface, and is not limited thereto, and is within the scope of the present invention.
綜上所述，本發明提供一種輸出介面資訊的回報方法及其相關電腦系統，使作業系統可正確地確認並顯示輸出介面資訊，進而提升使用者使用時的便利性。 以上所述僅為本發明之較佳實施例，凡依本發明申請專利範圍所做之均等變化與修飾，皆應屬本發明之涵蓋範圍。In summary, the present invention provides a method for reporting output interface information and related computer systems, so that the operating system can correctly confirm and display the output interface information, thereby improving the convenience of the user.
