Today, Den is in the class, the teacher opened the computer, entered the slide playback interface, and found all the color of the display. Many pictures have fallen. The teacher said that this is definitely a problem, which is a strong computer in the class. At that time, I immediately wanted to rush, because this is obvious that color depth is not adjusted, and now the color should be 256 colors, but If I think if it is not that, I can look at it. So the first half class I have been thinking about this, the host is locked, so it is impossible to be the graphics card is broken, the only one may change the color deep, but the slide is like color edge than 256 Still low, then, it should be 16 colors. Later, I took a closer look at some colors, all agreed with the color of the crayons played in a child, so it is determined that the color is 16 colors (rather than 16 color ^ - ^), the first half of the class is constantly appearing in the teacher. " This picture is now black and white, can't be colored, oh! "The sigh in the sigh. In the get out of class, there is a classmate (hereinafter referred to as Zhejiang, because he seems to be the frank country), he will open the "System Properties" dialog, and search for a while, no fruit; open "control Panel ", no fruit; I don't think he doesn't make a deep color, it is a rookie! So I also ran up, said to him: "Classmates, let me try" he said, I just click on the desktop, click "Attribute" - "Set" tab, pull down in the color of the color! ! ! There is only 16 colors of one option! ! When Zhejiang said, I just said that only this option ....... I understand this, in fact, the teacher didn't think of the color, I didn't think it, just sitting in the back row, I didn't see it. I will go. How to do? I got at the scene last time, it was a scenery, this time I can't go back, even if I can't fall to the ending of more gray face! I set up the god and started to analyze: this computer is much better than my Caiyang 300, and the color is definitely 32, the reason why there is only one reason: someone has changed the registry privately! So how do you find the key value of the bastard modification? I am not very good at the registry, so I will try "Group Strategy"! However, most of the discovery group strategy is about system security options, to set hardware options, it seems to be able to register. Open the registry, find the following key value: HKLM / Hardware / devicemap / video I stopped here, it is stopped here, its key value is / device / video2, I decided to change / device / video2 to / device / video3 At this time, Zhejiang said, watching the key value of the above / device / videoox, don't make a mistake. I looked carefully, didn't see anything, anyway, I just said, "I don't want it!" Select Explorer.exe, you can take effect as long as you get the process. Look at his unskilled operation, you know that this skill is learned from Windows 98 (because I have seen this skill, but I have seen the master. Commentary said that this trick is inheritance, this is the difference between the master and the mediocrity ^ - ^).
I insist on restarting, and he has finally consent. In dozens of seconds in the system, I clenched the fist (because if the registration form was changed wrong, the consequences were very serious!), Fortunately, all successfully entered the system. The instant of the desktop Zhejiang said it is good, see the color of the desktop. I don't worry, I also read the desktop properties: 32 colors! At this time, my mood can only use a song name to describe: When I am in my mind, the teacher came over, the teacher came over, tried to ask: "Practice it?" I was very chic microphone. "Practice it!" Went down to the podium. Later, the teacher went to Zhejiang, because he was the first to run, I saw that he used his hand when he was talking to the teacher, and the estimated content is nothing more than "I didn't do anything, most of them. The classmates do, but if you say that he is also credit, if he doesn't stand on the podium with me, I may be worried about being alone. When I went to the toilet when I was in the class, I was gone through the teacher, I said that the teacher is good, she asked me where you are, I have met, the teacher said that you are very powerful. Well, thank you, I feel good at the time! Postscript: Go back to sleep to do test on his own machine, find hklm / hardware / devicemap / video, video0, video1, video2 respectively correspond to different graphics compatibility patterns, this is like this: videO0 correspondence / registry / machine / System / ControlSet001 / Services / nv4 / Device0VIDEO1 corresponding to / REGISTRY / Machine / System / ControlSet001 / Services / VgaSave / Device0VIDEO2 corresponding to / REGISTRY / Machine / System / ControlSet001 / Services / mnmdd / Device0 i.e., mode 0 corresponds to the monitor under normal conditions, 32, 24, 16-bit color, mode 1 correspond to the initial standard VGA, in this mode, the ability of the graphics card is limited to 16 and 256 colors, and the mainstream configuration of the DOS era does not have the difference model 2 correspond to a single year The color shows the adapter, that is, MDA, which can only display text, can be said to be the most primitive, the oldest graphics card.
