The screen of the monitor is inverted!! Very depressed

Oh......It's so unusual......I guess someone else took advantage of your inattention and turned your monitor upside down, right......Hehe.

So the most direct and effective way is to turn it upside down again!!

This is due to the integration of the Inel i855 graphics card.

It defaults to Ctrl+Alt+Up, Down, Left, and Right to change the screen.

Press the alt+ctr+the key to move down to try (the one that moves the cursor down),,I used to seem to have the screen reversed.,The one behind me who just got it down.,.

Take a look at the graphics card properties.

Right-click on the desktop and adjust it in Advanced Rotation.

It's a virus, it could be a shock wave, Rising kills it.

In the display properties, the intel option will be flipped 180 degrees to restore it!

I've been in this situation before, and you can just press Alt or Ctrl+Down Down.

I think there's something wrong with the graphics card attributes, try tweaking it!

Take a closer look at your graphics card instructions, it can be adjusted.

You can't be the one who turned the monitor upside down.

Hehe, I also think it's OK to put it upside down, hehe.

Haha, I think you're right! It's good to have it upside down haha!

I've encountered it before and don't know why.

Fortunately, it is installed with XP

That's it with System Restore.

Let's reinstall the system. Simple and clean.

This can be transferred, the specific method is said by the people below.

Put your monitor upside down!

The vast majority of LCD monitors on the market today use 6-bit panels. Here I will first introduce to you the difference between 6bit and 8bit, the LCD has three color channels r, g, b, when each channel can not be compensated by acquired technology to reach 256 (2 to the 8th power) level of grayscale display, that is, 256*256*256 is equal to color, we call such a panel 8bit panel. And 6bit can only display 64*64*64 gray scale, and finally through hardware jitter and other technical means to make it able to display the color, so the 6bit panel can not be compared with 8bit in color.

The 8-bit panel has three main features, high contrast, ultra-wide viewing angles, and a relatively slow response time. At present, the panel on the market is divided into 3 categories according to its technology, VA, IPS and TN, of which VA is divided into MVA and PVA, MVA is a technology of Fujitsu, and PVA is the further development and continuation of Samsung in MVA technology, IPS is a liquid crystal technology developed by Hitachi, which can greatly improve the contrast and viewing angle, and increase the degree of color restoration, so the panel made by the above two technologies must be regarded as 8bit panel.

The last one is TN technology, which is synonymous with cheapness, although its viewing angle is small, but by pasting a wide-angle compensation film on the surface of the TFT LCD, the viewing angle immediately increases, and because the TN panel is a typical 6-bit panel, the number of color displays is relatively small, so the response time of grayscale is usually relatively fast. Wide viewing angle + ultra-fast response time + cheap, most consumers are attracted, see this, you should understand that buying LCD is not only to judge its quality by the speed of response time, color is also a very important factor.

Problem Analysis:

There are two situations when the computer boots up and the monitor does not respond: the monitor is not powered on (the power indicator is not on) or the monitor is powered on (the power indicator is on) but there is no signal or the screen shows "no sighal", the former means that the circuit is not on, or the power interface or power cable is in poor contact or damaged, and the latter is generally due to loose or oxidized memory modules and poor contact, or the display data cable is not in good contact, or the memory, graphics card, display or data cable is damaged.

Handling suggestions:1If the monitor is powered on but no signal is displayed, turn off (if the short press of the power switch is invalid, press and hold the switch until the power indicator goes out or directly unplug the power cord) Power off the case, replug and unplug the memory module, and wipe the gold finger with an eraser in one direction (the back of the thumb fingernail is also fine), if possible, it can also be installed in different memory slots, and then turned on after installation (before operation, you should also touch the wall with both hands to release your static electricity or wear anti-static gloves). If you can't do it, then it's simpler:

Palm or kick the chassis once or twice (pay attention to the location: the front of the shell on the left and right sides of the chassis that does not have an interface at the back; Attention said: Don't push too hard, of course, don't be weak).

The above may need to be repeated, and if it doesn't work, you need to replace the memory module. If you have more than two memory modules, you need to test them one by one.

2.If the above operations do not work, turn off the power and turn on the chassis, reinsert the graphics card, and plug in the data cable between the monitor and the graphics card. If it still doesn't work, consider that the cable or graphics card is damaged, then replace it with a new one.

3.If the monitor is not powered on (the indicator light is not on), check whether the power switch is turned on, then check the back of the monitor, plug the power cord connected to the monitor upwards (the power cord can be replaced if possible), and check whether the other end of the power cord is powered on to the outlet.

4.If the display can be displayed when connected to another monitor or the display of this machine is connected to another normal host and still cannot be displayed, it means that the monitor is damaged and needs professional repair.

If the VGA cable is not plugged in, check the cable interface behind the case and under the monitor.

It's not plugged in, look behind the monitor.

Hello:——1. Displays (including traditional CRT displays and liquid crystal displays) use switching power supplies with high efficiency, which is a fault that is difficult to start the switching power supply.

2. The reasons for the difficulty in starting the switching power supply are: the starting resistance becomes larger, the amplification of the switching transistor decreases, etc. This type of failure usually occurs in CRT displays and LCD displays where the power supply is integrated with the display.

3. It is relatively easy to repair the difficult maintenance of the switching power supply.

Legendary warm-up? What model do you monitor.

In this case, most of them are soft faults of the display switching power supply. It is recommended to ask experienced professional and technical personnel for maintenance.

Uh, it's recommended to learn the basics for about a month before doing it, otherwise it's counterproductive...

Or find a professional to plug and unplug and clean up, and the problem will increase by yourself...

Don't move, it's a minor problem, if you finish moving, it will become scrap, take it for repair, and the hardware (memory or graphics card) will be loose.

Dismantle the CPU, my god, don't touch it, don't burn it, you'll regret it when it's over!

It should make you replug it into memory (which is also unreliable to be honest)! The reason for the indifference is very small and the memory is very small, this situation I think is a graphics card problem, and the CPU has little to do with it, it is highly recommended to go to the maintenance office, I don't know how to disassemble it casually, it's easy to finish.

Don't touch the memory, this thing will burn if it's not good, I've met it, and there are a lot of them, and they won't mess up by themselves, and when you take it to repair, you can see that this memory is burned.

When I opened the lid of the case, I saw a fan on the motherboard, and there was an aluminum heatsink under the fan, and the CPU was under the heatsink.

Seeing that you ask this question, you should not understand, it is recommended that you find someone who understands or send it for repair.

Otherwise, after you remove it, it is estimated that you will not install the CPU in the direction of the disassembly, you will look carefully when you disassemble it.

You unplug the cable and check it again, or you make the resolution of the monitor a little bigger. , preferably 1024x768 so that's fine.
