Description
Technical field
The present invention relates in the multi-screen expansion by suitable minimizing viewing area better to take into account the system and method for video adapter performance and user's visual experience.Specifically refer to a kind of system and method for optimizing the multi-screen viewing area.
Background technology
Computing machine be presented at wide screen video, virtual emulation or recreation occasion often need to surpass uses many displays to constitute surrounding effect, with enhancing user's vision feeling of immersion and validity, realize that unicomputer multi-display surrounding effect can adopt one or more special display card directly connecting multi-screen output multi-screen on a plurality of output interfaces or adopting external multi-screen expansion equipment to expand the single output interface of video card to a plurality of display devices.
No matter be to adopt video card directly to export multi-screen or the external expansion multi-screen of employing, main flow generally adopts 3 super three wide screen display effects of the horizontally-spliced compositions of display around multi-screen at present, this demonstration has brought three times of horizontal expansions of picture, and vertically constant.Because display device was that the master is converted to 16: 9 or 16: 10 masters by 4: 3 progressively, this means that separate unit display change itself is wideer than originally, three displays like this are horizontally-spliced will to make the whole image non-constant width that becomes, because excessive length breadth ratio picture imbalance can cause the part virtual application, recreation and video are vertically compressed because of seeming on the contrary and have been reduced the sense of reality.Use three screen systems simultaneously, because most of virtual reality softwares or Games Software specially are not multi-screen optimization, therefore the image information that shows can be evenly distributed in three displays, the important information that causes needs to show is presented on the two-sided display, being still that sight line is mainly paid close attention in video and recreation for the user is positioned at middle screen, especially in emulation fields such as virtual drivings, intermediate screen is especially as the emphasis of emulation flesh and blood, and the both sides screen is mainly used to produce around feeling of immersion, when the too much quilt of important information squeezes the decline that also can cause the user to experience when shifting the both sides screen onto.Will see that also the horizontal expansion of viewing area also can increase the burden of video card, and the unessential relatively information in edge, both sides consumes video card too as picture resource if therefore can suitably reduce the width of picture, also will be optimized the output performance of display card.
And in the single multi-screen expansion technique that outputs to many display devices that uses that external expansion technique expands video card, reduce the integral width of viewing area, also can bring extra advantage, because being subjected to the restriction of single video card output interface bandwidth, the final image expanding size of external interface expansion equipment can not realize that single DVI interface or the total effectively pixel frequency of three demonstrations all over the screen of Displayport interface expansion surpass the display (as the display of three 1920 * 1200@60Hz or 1920 * 1080@60Hz) of 330Mhz, if can suitably reduce the width of output image then can satisfy total effectively bandwidth requirement of pixel, realize the more multi-screen expansion of giant-screen of the external expansion of single interface.If reduce to export and show that the problem that picture traverse brings is if evenly expand to many Output Display Units or can not give prominence to center display frame, picture after directly will reducing simultaneously outputs on many displays, to cause the output display resolution not meet the display standard or be not the display optimum resolution, the result who brings can't show or stretched by wrong.
In sum, consider the variation of display technology, for visual effect and the user who optimizes demonstration experiences, optimize the performance of video card and the ability of external multi-screen expansion, the display output format that can also keep center display frame size simultaneously and maintain the standard is necessary that to guarantee correct output the method that designs a kind of optimizing computer multihead display zone addresses the above problem.
Summary of the invention
Technical matters to be solved by this invention is to provide the system and method in a kind of optimizing computer multihead display zone, being used for optimizing the visual effect and the user that show experiences, optimize the performance of video card and the ability of external multi-screen expansion, can also keep center display frame size simultaneously and the display output format that maintains the standard to guarantee correct output.
For addressing the above problem, the present invention adopts following technical scheme: the system of a kind of optimizing computer multi-screen viewing area, this system comprise computing machine, the adapter that connects with computing machine and the identical display device of some resolution that is connected with adapter; Described adapter comprises demonstration information acquisition module, the input/output format configuration module, the EDID information module able to programme that is connected with the input/output format configuration module respectively, the non-homogeneous black plug module that are connected with demonstration information acquisition module and cuts apart output module.
The present invention also comprises the method for a kind of optimizing computer multi-screen viewing area, and this method may further comprise the steps:
1) obtains many required display resolution information of display device by demonstration information acquisition module;
2) the input/output format configuration module receives the required display resolution information that the transmission of demonstration information acquisition module comes, convert the configuration parameter of input and output in conjunction with display device picture minimizing value, and pass to EDID information module able to programme, described EDID information module able to programme is used for producing EDID information according to the input and output configuration parameter, and send request according to this information to computing machine, require computing machine to send to reduce the image behind the picture;
3) non-homogeneous black plug module receiving computer sends the image that reduces behind the picture; And the black image of the image equal number that inserts and be reduced in the image both sides that are reduced;
4) cut apart output module will be image behind the black plug output to a plurality of display devices after evenly cutting apart.
The present invention is by the picture width of adjustable suitable minimizing multihead display output, but still the monitor resolution of the standard of support input, the optimization of the sense of reality of the outstanding and multihead display of realization center display frame, can also optimize simultaneously the output performance of video card, in external multi-screen expansion, can also support the use of the multihead display device of bigger resolution.
The present invention relates to a kind of non-compression video signal and in the passage that limits the dot frequency bandwidth, handle the method for vision signal, this method can keep the video valid pixel not have fully under the prerequisite of loss, realize the conversion in black-out of video signal cycle, compensation is owing to outputting video signal nonstandardized technique or pixel that the bandwidth restriction causes are lost.
