Important points to keep in mind when choosing to buy LCD monitors

Aesthetics : Compared to CRT, the LCD screen has a trendy and sleek look. The products now have elegant designs, neatly arranged control bars. The volume of a 15 'LCD monitor is just over 1kg, a little heavier at 17', very convenient for moving. In addition, manufacturers have designed power sources outside so the minimum thickness of the current screen background is less than 1.5cm.

Viewing angles : Although CRT leads the way in this respect, the viewing angle of the LCD is further expanded. The LCD's maximum viewing angle is now larger than 160 degrees - more than enough for any purpose.

About color display : CRT screen clearly dominates. However, the best LCDs today also respond quite well and for ordinary users it is difficult to recognize the difference when compared. The difference in this color display can increase or decrease the quality of LCD screen compare.

Contrast : Traditional CRT always has better contrast than LCD. Recently some LCD products have caught up with CRT screens in this capacity. Contrast displays true color tones even when the light is low. Therefore, this is the most important factor for game or movie applications.

Dead spots: Dead spots are inactive pixels on the LCD screen. Cannot fix the dead point of the screen. The dead spot will be visible with a white background or on startup. There are still many manufacturers wondering about the replacement warranty terms for screens with dead spots.

About image display: LCD screen displays 2 times brighter images than CRT. It is recommended to choose LCD when using the monitor in a bright environment.

Magnetic noise : LCDs are not affected by magnetic noise - unlike CRT. Many LCD monitors have a built-in stereo system and do not have to prevent magnetic noise. Thus reducing the costs for consumers and manufacturers.

Response speed : For LCD monitors, response speed is an important factor related to game or movie applications. It is time that a pixel on the screen can change color. Currently most monitors have high response speed. You should choose a screen with a response time of at least 2ms if you need to play the game.

Flickering : The most inconvenient aspect of CRT monitors is vibration, or low scanning frequency, which can cause headaches when used daily. This makes the CRT monitor manufactured more limited. The default scanning frequency in Windows is 60 Hz, until the screen is installed, the operating system will receive the installation file and adjust the frequency according to the parameters of the screen. According to the VESA standard, the minimum scan frequency is 72 to avoid eye strain. 85 Hz is the ideal frequency for 17-inch CRT users. Scanning frequency is not a problem for LCD monitors at all. Usually there are two types of scan frequencies to choose from for LCD monitors, so follow the manufacturer's recommendations
