Refresh rate refers to the screen image of the update
understand what is called "4K alignment". The so-called "4K alignment" is consistent with the "4K sector" definition of the formatted hard disk, and according to the "4K sector" rules
4K performance can be simply understood to mean that 4K random Read and write performance represents the data throughput capability (in IOPS) of the hard disk and is relative to continuous read and write performance. In the daily application of the Web page cache writing, System file updates, including programs, game loading, response, etc. are closely related to
This problem is often encountered. You can change the monitor and then change the resolution back to the monitor. However, this method is quite practical and troublesome. Here is a simple method: 1. Most people can think of entering the safe mode, modifying the resolution,

The LCD has the following differences from the CRT monitor. Note One: Refresh frequency The refresh rate is the vertical scan frequency (field frequency) of the monitor, which refers to the number of times the electron gun is scanned across the screen per second, in Hz (Hertz). For CRT monitors, the image displa

CRT displays (the scientific name "cathode ray tube") is such a device, it mainly by the electronic gun (electron gun), deflection yoke (deflection coils), shade mask (Shadow mask), high pressure graphite electrode and phosphor coating (phosphor) And the glass shell is composed of five parts. One of the most impressive is the glass shell, also known as a fluoresc

Because the dots, lines and faces on the screen are made up of pixels, the more pixels the monitor can display, the finer the
. The third taboo: hard object attack The liquid crystal is softer and easily damaged (except for the glass screen outside). So when used in peacetime must be careful not to touch the screen with hard objects. The fourth taboo: long time to use Because the LCD is not simple, its pixels are built by a large number of LCD, for a long time continuous use, will make the crystal aging or burn out. Once the
The visual angle is the angle by which the user can observe all the contents of the screen clearly from different directions. Because the provision of LCD display light source refraction and reflection after the output has a certain direction, in excess of this range of viewing will produce color distortion, CRT monitor will not have this problem. The visual angle size determines the size of the user's visu
