Solution for failing to reach standard resolution with integrated video card wide screen

I forgot where to transfer it. Haha.

A friend recently bought a 19 inch-inch wide-screen LCD. No matter how it is adjusted, the screen is distorted and uncomfortable. As a result, my friend found this "high person" and finally solved the problem after several twists and turns. The author "Baidu" later found that this problem is common, especially for users who are using SIS or via chipset integrated graphics card. The following are some experiences in solving this problem.

In fact, I am also the first to come into contact with this kind of problem, but I am also a little familiar with the reasons for this phenomenon. Update the video card driver by setting the system resolution (or using PowerStrip to add resolution options) based on your previous experience.Program.

First, right-click the desktop and select "properties", and click "Settings> advanced> Tool Manager> driver mode settings". The system finds that the 19 inch wide screen resolution (1440 × 900) is not supported). With CPU-Z to view the motherboard information, found that the motherboard is Foxconn 661fx-7ma, this is an integrated motherboard using SIS chip, to the driver home or official website to download the latest graphics card driver, the problem still does not support wide screen resolution. I checked the information on the Internet with Baidu and found that the BIOS version of the video card is lower than 2.30 and it is impossible to support wide screen resolution. Adding resolution options through PowerStrip does not work.

In this case, the solution will come out. I downloaded the latest bios and refresh tool for the motherboard from the official website, and then updated the BIOS of the motherboard in Windows XP using winflash released by award. The update process is very simple: Double-click winflash, select "File> updatebios", find the path to save the bios, and click "open" to start refreshing. After refreshing, restart the system. Later, I found that the video card BIOS version and resolution support options have changed, so that the system can correctly support the wide screen LCD resolution.

Advanced: motherboard biosdiy

Currently, some manufacturers do not pay much attention to the wide screen resolution supported by integrated graphics cards, so they have not updated the BIOS. What should I do if I encounter such a problem? You can use CBROM to create one by yourself. For ease of operation, I renamed them old. Bin (wide screen resolution not supported) and new. Bin (wide screen resolution supported ). The operating principle is to use CBROM (the latest version is 2.19) to extract the VGA (display part) module from the BIOS of the motherboard that supports wide screen resolution, and then replace the VGA module in the BIOS of the motherboard that does not support wide screen resolution. The detailed steps are as follows:

Step 1: Download cbromv2.19 and copy CBROM, old. bin, and new. bin to the C root directory;

Step 2: Click Start> Run. In the displayed dialog box, enter the CMD command to enter the system command prompt environment. Use "CD .. "command to return to the system root directory (C: \>), enter" cbrom219new. bin/d (note the space) command and press enter to view the VGA module in BIOS.

Step 3: Use the extract parameter of CBROM to extract the VGA module from new. Bin. The specific command is "cbrom219new. bin/vgaextract". After you press enter, the system will prompt you to enter the file name to save the file. Generally, you can use the original file name.

Extract VGA module from BIOS

Step 4: run the "cbrom219old. bin/D" command to view the vag module in old. Bin. Then, use the release command of CBROM to delete the video card BIOS file. Run "cbrom219old. bin/vgarelease" to delete the module and press Enter.

Step 5: run the "cbrom219old. bin/vga6330vga. Rom" command to add the 6330vga. ROM file to the old. binfile, so that the BIOS of the motherboard that supports the wide screen is created.

Add the VGA module to the new BIOS

In fact, for some motherboard With the same north-south bridge, you can also use the BIOS brush method, of course, relatively higher risk. However, only upgrading the BIOS is not enough. The matching driver is also one of the necessary means for the integrated motherboard to support wide screen resolution.

Although awardbios is used on most of the main boards, there are still many bios on the Main Boards that use AMI. Because the use of amibios is relatively less, once the integrated graphics card of this type of motherboard does not have the resolution of the wide screen display, it will be a little more troublesome. Here we will introduce a modification tool mmtool for editing amibios, which can be used to graft the award graphics module to amibios. The procedure is as follows:

Step 1: Use CBROM to separate the video card modules that support wide screen resolution and save them to the C root directory.

Step 2: Install and run mmtool, select "mmtool advanced" mode, click "load Rom", and select the BIOS path to be modified. Click "replace", select "Browse" in "module File", and add the separated graphics card module.

Add VGA module for amibios

Step 3: select the first pcioptionrom with ID 20, and click "replace" to replace the original low-version video ROM file. The default values of "module ID", "vendor ID", and "device ID" must be kept. Do not make any changes.

Step 4: Use the BIOS refresh tool of the AMI to refresh the changed BIOS file, so that the AMI's old BiOS supports the wide screen resolution by porting the Award bios. How about DIY!

conclusion: based on the current situation, integrated graphics cards that do not support wide screen resolution are mainly concentrated on the Via and SIS chipset. If this problem occurs on the motherboard via or SIS integrated graphics card, you can solve it through the above method. Simply put, the key point of not supporting the wide screen is that the BIOS of the video card module is too low. By updating the BIOS of the motherboard and matching the appropriate video card driver, the Integrated Video Card can no longer be afraid of connecting to the wide screen display.
