The role of the LCD phase and how much adjustment is appropriate

I don't know much either, I usually tune according to the recommended parameters!

Phase is the near-long-term phenomenon that occurs when adjusting the center to look at the display.

Phase is usually measured in degrees (angles). When the signal waveform collapses and changes in a periodic manner, the waveform cycles for one week and is 360. The principle of phase protection is to compare the positive and negative values of the instantaneous values of voltage and current of each branch, and combine the detection and output control protection circuits to achieve the purpose of protecting the equipment.

There is no fixed correct value for the setting of the phase, and this problem is generally solved by selecting "Auto Adjustment" or in the monitor menu, and some monitors still can't solve it after adjustment, but it does not affect the use.

Basic introduction to the display phase:

Phase is the position of a wave in its cycle at a particular moment: a scale of whether it is at a crest, trough, or somepoint in between. Phase describes a measure of the change in the waveform of a signal, usually in degrees (angles), also known as phase angles.

When the signal waveform changes in a periodic fashion, the waveform cycle is 360°.

Phase Adjustment Method:

Refers to a control mechanism installed on some subwoofers. It is used to slightly delay the sound reproduced by the subwoofer, so that the output of the subwoofer can be in phase with the front main speaker, i.e. have the same time relationship.

The phase is the adjustment center, that is, for example, when you look at the monitor at 15 degrees on the right side, there will be a phenomenon of near-long-term short-term. If you adjust the phase, you can eliminate this visual problem. But it's usually just in front of the level**, so this option is almost useless.

1 Displays produce horizontal streaks: there are two main reasons for this:

1) External interference, such as electric sparks or high-frequency electromagnetic interference near the use site of the display, this interference will make the display screen of the display produce white horizontal stripes Processing method: avoid using the display in this case;

2) Internal interference, this interference will make the display screen of the display appear black horizontal stripes, in this case, you can open the case to check whether there is a bad contact inside the display, whether there is a problem with the output end of the power supply or the output transformer, etc., because the reasons for this situation involve more professional technology, so it is best to ask a professional to repair it.

2 Improper display resolution setting causes blurred screen: When the monitor is set incorrectly in the resolution of win95, there may be a blurred screen failure when starting windows, that is, the picture layering jitter is serious and even the phenomenon of black screen of death is dealt with: enter the setup or enter the safe mode of win95, and reset the display mode of the display.

3 Conflict between the display card and the Chinese system: In this case, when exiting the Chinese system, there will be a blurred screen, and there is no response to random keystrokes, similar to a crash, processing method: input at this time"mode c080"can be resolved.

4. Poor heat dissipation effect of the main control chip of the graphics card: This will also produce the phenomenon of blurred screen failure, and the solution is to improve the heat dissipation performance of the graphics card.

5. The video memory speed is too low: When the video memory speed is too low to match the speed of the host, the screen will also be blurred, and the solution is to replace the video memory with a higher speed, or reduce the speed of the host.

6 Video memory corruption: When the video memory is damaged, there will be a phenomenon of blurred screen messy characters when the system starts, and the solution is that the video memory bar must be replaced.

7.Virus cause: Some viruses will also appear when the screen appears, and the solution: use antivirus software to eliminate it.

If you adjust the potentiometer, then you can adjust it back slowly, but it turns out to be blurry, and it is impossible to fix it after adjustment.
