201133333 六、發明說明： 【發明所屬之技術領域】 本發明係關於一種顯示器模擬裝置，尤指一種可模擬 為一顯示器，讓所連接的訊號來源（例如電腦）視為一顯示 器，並設定顯示器解析度及更新率的顯示器模擬裝置。 【先前技術】 按’ 一般電腦顯示器皆因其尺寸規格而有其可支援及 • 最適合的解析度及更新率；而顯示卡驅動程式則内建有基 本靜態顯示模式，其包含顯示卡廠商所設定之色彩深度及 解析度’例如在色彩品質達到32位元的設定下，顯示卡 支援的解析度包括 640x480、800x600、1024x768、 1280x1024及1600x1200。當顯示卡與顯示器連接後，顯 示卡在與顯示器溝通的過程中，先自顯示器取得其内建的 更新率（refresh rate)設定值及顯示時序（djsp丨ay tjmjng)設 定值後，再依所取得的更新率設定值及顯示時序設定值輸 镰出視訊資料’其中更新率設定值之高低會影響顯示器畫面 更新的速度’通常是越高畫質越好，惟一般顯示器廠商均 將更新率設定值定在最常用的60Hz ;而顯示時序設定值 則包括了水平前遮斷（horizontal front porch)時間、水平後 遮斷（horizontal back porch)時間、水平同步寬度 (horjzontal sync width)、垂直前遮斷（vertical front porch) 時間、垂直後遮斷（vertical back porch)時間及垂直同步寬 度（vertical sync width)，其影響畫面能否正確地滿屏顯示 在顯示器正中央而不偏移。 201133333 然而，由於顯示器與顯示卡的廠商不同，間接地導致 顯示器與顯示卡之間時常發生無法互相支援的問題。首先 是解析度不相容所引發的問題，例如，若顯示卡驅動程式 内建的最高解析度僅到1280x720,而顯示器的最適合解 析度是1440x900,將有可能導致無法在顯示器上顯示滿 屏或是偏移的畫面；雖為解決此問題，大部分顯示器會進 一步内建有自動縮放器（Scaler)，該自動縮放器的作用在 於，當其察覺到顯示卡傳來的視訊資料時，會判斷其是否 • 能在顯示器上以滿屏方式顯示，若判斷結果為否，則顯示 器會自動將晝面縮放至滿屏，故使用者毋須自行調校顯示 卡輸出之視訊資料的解析度設定值；惟相對地，如此設計 將有可能導致畫面因不正常的放大或縮小而失真或變形。 再者’有些顯示器廠商會因特別的需求，不依視訊電 子設備標準制定協會（Video Electronics Standards Association，簡稱VESA)所制定的標準，而自行定義其出 1S1 廠顯示器的顯示時序設定值，因而導致在顯示器上顯示的 ® 晝面發生偏移的現象，例如若垂直前遮斷時間太短會導致 畫面向上偏移的情形。當此情形發生時，因傳統的陰極射 線管（cathode ray tube，簡稱CRT)顯示器大都有提供使 用者手動水平或垂直調整畫面的功能（〇Sd，〇n sc|_een display) ’故使用者尚不致對此感到困擾。而目前較普遍 的液晶顯示器雖亦有提供此項功能，但只有當視訊來源是 透過D-Sub連接器取得的類比視訊資料時，此功能才能發 揮其作用’如視訊來源是透過DVI連接器取得的數位視訊 資料時’此項調整畫面的功能則無法使用，因此若使用者 4 201133333 面遭遇畫面偏移的問題，將完全束手無策。 此外，因目前市面上有許多低價的顯示器在流通，而 這些低價的顯示器之所以可以低價格販售主因在於其省 略了：些穩定線路用的零件，或是使用較便宜的零件。然 而，這些'低價顯示器名 p因此有卉多問題，例如訊號傳輸距 離無法達到標準傕，4·、e y „ , 或疋靜電防護效果不佳造成低價顯示 器在60Hz更新率時舍 ..^ ^ t會產生雜訊，其中後者又因顯示器廠 商通常將更新率定在6〇μι b0Hz的做法，導致使用者完全無法 解決雜訊問題。 再者’當顯示器應用在多畫面顯示時，例如電視牆， -月參閱第\圖所不’電視牆係由複數個顯示器(4〇)排列構 成-口使用旦面分割軟體將原始影像畫面分割為多個子 畫面後，再令該複數個顯*器（4〇)分㈣示對應的子畫面， 如此即可由該複數個 ··" /、器（40)所顯示的子晝面’組合顯 不為較大的原始影像畫面β 右’、中•不益（4〇)損壞’或是顯示器（40)與顯示 =間的連線脫落導致訊號中斷時，將導致訊號來源的畫 面为割軟體計算出現錯誤， ^ 因而停止對原始影像畫面的分 工作’造成其餘未損壞 _ .^ Η 艰之顯不态（40)或仍正常連接顯示 卡的顯示器（40)無法繼續顯 ^ ., as _ 員不經分割的子畫面’而僅能獨 立地顯示原始影像畫面（ 第九圖所示）。如此一來，縱將 才貝壞之顯示器（40)修復或是 渣人齋.a Α 疋口復其與顯示卡之連線，仍無 去令電視牆回復顯示較大的 仍口处 的原始影像晝面，各顯示器（40) 仍/、犯獨立地顯示原始影像 上仍相當麻煩。 象晝面(如第十圖所-)，故使用 201133333 【發明内容】 為此，本發明之主要目的在提供一種顯示器模擬裝 置’可模擬為一顯示器，讓所連接的訊號來源視之為一顯 示器’並令顯示器依内建的解析度和更新率設定值正確地 顯示最佳視訊資料。 為達成前述目的所採取之主要技術手段係令前述顯示 器模擬裝置包括： φ 一殼體； 一第一連接埠，係設於該殼體上，供與一訊號來源連 接以取得視訊資料； 一第二連接埠，係設於該殼體上，供與一顯示器連接 以顯示視訊資料； 一模擬模組，係設於該殼體内，並連接於該第一連接 谭和第二連接埠之間’又該模擬模組係儲存一顯示器韌 體、一最佳解析度值、至少一更新率設定值及一模擬程序， • 忒模擬程序係由該模擬模組執行，當該模擬模組偵知該第 一連接蟀與訊號來源連接時’即執行該顯示器韌體，並將 該最佳解析度值及該至少一更新率設定值經由該第一連接 埠傳送給訊號來源。 利用上述技術手段’由於該模擬模組儲存有顯示器韌 體故對該訊號來源（例如一電腦）來說，可將本模擬裝置 視為一顯示器；另一方面，藉由該模擬模組將最佳解析度 值及更新率設定值傳送給訊號來源，使訊號來源可依該最 佳解析度值及更新率設定值輸出視訊資料，經過本模擬裝 6 201133333 置後由該顯示器加以顯示，如此一來，可有效解決既有顯 示卡和顯示器之間因由不同廠商製造所導致更新率不相容 的問題。 【實施方式】 請參閱第一圖與第二圖所示，本發明之顯示器模擬裝 置（10)係用以連接於一訊號來源，例如電腦（20)，以及一 顯示器（30)之間。另請參閱第一圖和第三圖所示，本發明 • 之第一實施例，係包括一殼體（1 1 )、一第一連接埠（1 2)、 一第二連接埠（13)及一模擬模組（14)。 上述第一連接埠（12)係設於該殼體（11)上，供與該電 腦（20)連接以取得視訊資料；較佳地，該第一連接埠（I?) 係符合數位視訊介面（Digital Visual Interface，簡稱DVI) 標準。 上述第一連接璋（13)係設於該殼體（1.1)上，供與該顯 示器（30)連接以顯示視訊資料；較佳地，該第二連接埠 • 係符合DVI標準。 上述模擬模組（14)係設於該殼體（11)内，並連接於該 第一連接埠（12)和第二連接埠（13)之間，又該模擬模組（14) 係儲存一顯示器韌體、一最佳解析度值、至少一更新率設 定值、一顯示時序設定值及一模擬程序，其中： 該最佳解析度值可由廠商自行設定，用以定義透過本 模擬裝置所輸出視訊資料之最佳解析度，由於本模擬裝置 所提供的是一最佳解析度，故與一般電腦顯示卡配合時， 皆可提供向下相容的功能；例如，若該最佳解析度值係 7 201133333 1920x1200 ’則本模擬裝置配合一般電腦顯示卡皆可向下 相容 800x600 、 1024x768 ' 1280x720 、 1280x1024 、 1440x900、1600x1200、1680x1050 解析度； 該更新率設定值亦可由廠商自行設定，且可為一組或 多組’例如若為三組更新率設定值時，更新率設定值可為 55Hz、60Hz及70Hz，其作用在於提供使用者更多更新率 設定值的選擇； 該顯示時序設定值係包括水平前遮斷時間、水平後遮 Φ 斷時間、水平同步寬度、垂直前遮斷時間、垂直後遮斷時 間及垂直同步寬度，且該顯示時序設定值係依視訊電子設 備標準制定協會（Video Electronics Standards Association，簡稱VESA)所制定的標準加以設定； 。玄模擬程序係由该模擬模組（14)執行，當該模擬模組 (14)偵知該第一連接埠（12)已連接電腦（2〇)時，即執行該顯 示器韌體，並透過該第一連接埠（12)將該最佳解析度值、 更新率設定值及顯示時序設定值傳送給電腦（2〇),讓電腦 ❿（2G)將本模擬裝置（1〇)視為—顯示器’ i由電腦（2q)上顯示 卡（圖中未示）的驅動程式將該最佳解析度值及更新率設定 值載入靜態顯示模式供使用者選用，如此電腦（2〇)可依該 顯示時序設定值和使用者選用的最佳解析度值及更新率設 定值輸出視訊資料，經過本模擬裝置（1〇)傳送至該顯示器 (30)加以顯示。 此外，該模擬模組（14)可進一步包括一用以處理數位 視訊資料的數位模擬單元（141)或是一用以處理類比視訊資 料的類比模擬單元，因此依照模擬模組（14)所具有的模擬 8 201133333 單TO (141)類型不同’使該第—連接蟑〇 2)和第二連接蜂⑽ 應對應符合DVI-D(數位）或DV|_A(類比）標準；又於本實施 例中’因DVI標準規範第]4接腳係—用以提供電源給待 機中顯示器的接腳，故該模擬模組（14)可據此透過該第一 連接埠（12)自電腦（2〇)取得工作電源。 另請參閱第四圖所示，該模擬程序係包括下列步驟： 偵知第一連接埠連接視訊來源（4〇彳）； 執行顯示器韌體（402);

Description of the Invention: [Technical Field] The present invention relates to a display simulation device, and more particularly to a display that can be simulated as a display, and the connected signal source (such as a computer) is regarded as a display, and the display is analyzed. Display and simulation device for degree and update rate. [Prior Art] According to 'General computer monitors, they have the support and the most suitable resolution and update rate due to their size specifications. The display card driver has a built-in basic static display mode, which includes the display card manufacturer. Set color depth and resolution ' For example, when the color quality reaches 32 bits, the resolution supported by the display card includes 640x480, 800x600, 1024x768, 1280x1024, and 1600x1200. After the display card is connected to the display, the display card is in the process of communicating with the display, first obtains the built-in refresh rate setting value and the display timing (djsp丨ay tjmjng) setting value from the display, and then according to the The obtained update rate setting value and display timing setting value output video data 'where the update rate setting value affects the speed of the display screen update'. Generally, the higher the picture quality, the better the display rate is. The value is set at the most commonly used 60Hz; the display timing set value includes horizontal front porch time, horizontal back porch time, horizontal hop width (horjzontal sync width), vertical front cover Vertical front porch time, vertical back porch time, and vertical sync width, which affect whether the picture is correctly displayed in the center of the display without offset. 201133333 However, because the display is different from the manufacturer of the display card, indirect problems between the display and the display card often fail to support each other. The first is the problem caused by the incompatibility of the resolution. For example, if the highest resolution built into the graphics card driver is only 1280x720, and the most suitable resolution of the display is 1440x900, it may cause the full screen to be displayed on the display. Or offset screen; although to solve this problem, most monitors will have built-in automatic scaler (Scaler), the role of the auto-scaler is that when it detects the video data from the display card, Determine whether it can be displayed on the display in full screen mode. If the judgment result is no, the display will automatically zoom the screen to the full screen, so the user does not need to adjust the resolution setting value of the video data output by the display card. However, in contrast, such a design may cause the picture to be distorted or distorted due to abnormal enlargement or reduction. Furthermore, some display manufacturers will customize the display timing setting of the 1S1 factory display for their special needs, not according to the standards set by the Video Electronics Standards Association (VESA). The phenomenon of the offset of the 昼 surface displayed on the display, for example, if the vertical occlusion time is too short, the screen will be shifted upwards. When this happens, the traditional cathode ray tube (CRT) display has the function of manually or horizontally adjusting the picture (〇Sd, 〇n sc|_een display). Not to be bothered by this. While the current more popular LCD monitors also provide this function, this function can only be used when the video source is analog video data obtained through the D-Sub connector. For example, the video source is obtained through the DVI connector. When the digital video data is used, the function of this adjustment screen cannot be used. Therefore, if the user 4 201133333 encounters a problem of screen offset, it will be completely helpless. In addition, there are many low-cost displays on the market, and these low-cost displays can be sold at a lower price because they are omitted: parts for stabilizing the line, or using cheaper parts. However, these 'low-cost display names p have many problems, such as the signal transmission distance can not reach the standard 傕, 4·, ey „, or 疋 疋 疋 造成 造成 造成 造成 造成 造成 低价 低价 低价 低价 低价 低价 低价 低价 低价 低价 低价 低价 低价 低价 低价 低价 低价 低价 低价 低价 低价^ t will generate noise, which in turn because the display manufacturer usually sets the update rate to 6〇μι b0Hz, which makes the user completely unable to solve the noise problem. In addition, when the display is applied to multi-screen display, such as TV Wall, - month see the picture is not 'TV' is composed of a plurality of displays (4 inches) - the mouth uses the split surface split software to divide the original image into multiple sub-pictures, and then make the plurality of display (4〇) points (4) show the corresponding sub-pictures, so that the sub-area 'combination displayed by the plural ···" /, (40) is not displayed as a larger original image frame β right ', middle • If the (4〇) damage is lost or the connection between the display (40) and the display= is disconnected, the signal will be interrupted, causing the signal source to be incorrectly calculated for the software, ^ thus stopping the division of the original image. jobs Causes the rest of the undamaged _ .^ Η difficult to display (40) or the display (40) that still normally connects the display card can not continue to display ^, _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ The image screen (shown in the ninth figure). In this way, the monitor (40) repaired or the scum person's connection with the display card is still not used to make the video wall. Responding to the larger original image of the original image, the display (40) is still quite cumbersome to display the original image independently. The image is used (as shown in the tenth figure), so 201133333 is used. Therefore, the main purpose of the present invention is to provide a display simulation device that can be simulated as a display, and the connected signal source is regarded as a display, and the display is correctly set according to the built-in resolution and update rate. Displaying the best video data. The main technical means adopted to achieve the foregoing objectives is that the display simulation device includes: φ a housing; a first connection port is disposed on the housing for connection with a signal source Take Video data; a second port is disposed on the casing for connection with a display for displaying video data; an analog module is disposed in the casing and connected to the first connection Tan and Between the two ports, the analog module stores a display firmware, an optimal resolution value, at least one update rate setting value, and a simulation program, and the simulation program is executed by the simulation module. When the analog module detects that the first port is connected to the signal source, the image firmware is executed, and the optimal resolution value and the at least one update rate setting value are transmitted to the signal source via the first port. Using the above technical means, since the analog module stores the display firmware, the analog device can be regarded as a display for the source of the signal (for example, a computer); on the other hand, the analog module will be the most The good resolution value and the update rate setting value are transmitted to the signal source, so that the signal source can output the video data according to the optimal resolution value and the update rate setting value, and the display is performed after the simulation installation 6 201133333 It is revealed this way, existing displays can effectively solve the cause of the problem caused by different vendors manufacture incompatibility between the update rate card and monitor.

For one or more groups, for example, if the set value is set for three groups, the update rate setting values may be 55 Hz, 60 Hz, and 70 Hz, and the function is to provide the user with more update rate setting values. The display timing setting value includes the horizontal front occlusion time, the horizontal back blunt time, the horizontal synchronization width, the vertical front occlusion time, the vertical back occlusion time, and the vertical synchronization width, and the display timing setting value is based on the video. Set by the standards set by the Video Electronics Standards Association (VESA); The simulation program is executed by the simulation module (14).

Interrupted, because the computer (20) has regarded the analog device (1〇) as a display, the computer (20) will not notice that the connection with the display (3〇) has been interrupted, and the computer (2〇) is executed. Face segmentation software can still be shipped normally Therefore, as shown in the seventh figure, only the display (3〇) that has been damaged or interrupted by the signal can no longer display the screen, and the other displays (30) still operate normally due to the screen segmentation software, so the original display will still be displayed. The facet' can be quickly restored to the original original image displayed as long as the damaged or broken display (3〇) is repaired or rewired. However, the present invention has been disclosed in the foregoing embodiments, but is not limited to the contents mentioned in the foregoing embodiments, and any changes and modifications made without departing from the spirit and scope of the invention belong to the protection of the present invention. range. In summary, the present invention has been significantly improved in effectiveness and complies with the patent requirements of the invention, and is filed in accordance with the law.
