One of the LCDs that refused to buy: 17-inch widescreen LCD
Speaking of LCD, I am afraid that many people first think of "widescreen". Indeed, although widescreen LCD is a new type of product, the brilliant achievements of widescreen LCD in 2006 are obvious to all. This year, widescreen LCD not only defeated The traditional LCD has become the absolute leader in the market, and at the same time has laid a solid foundation for the wide-screen display field.
To put it plainly: 17-inch widescreen LCD is not as good as 17-inch LCD
It may be that the widescreen is too hot. Many manufacturers spread the widescreen war to the 17-inch widescreen LCD, but from the market reaction, the 17-inch widescreen LCD is not popular. Although there are not many 17-inch widescreen LCD models on the market, there are two resolutions, namely 1280 × 720 and 1440 × 900, the former is 42% less than the resolution 1280 × 1024, and the latter is not Small (actually less than 1280 × 1024), but the pitch of 0.255mm poses a serious challenge to the user ’s eyes, so it is not surprising that the 17-inch widescreen LCD is not popular. And now the 17-inch widescreen LCD panel is also produced by some small and second-tier LCD panel manufacturers, and the display effect has no advantage.
In fact, there is another obvious reason for rejecting the 17-inch widescreen LCD. The trend of LCD development is high resolution and large size. The 17-inch widescreen LCD is contrary to these two items, destined to be a short-lived LCD specification, and also destined to be There are no promising LCD specifications, so we believe that the 17-inch widescreen LCD should be rejected.
â— Refusal to buy the second LCD: LCD without DVI interface
Although the LCD field still maintains an alarming development rate, in the face of benefits, the digital DVI interface still has not reached 100% popularity. Although refusing to have no DVI interface is a common issue, we think it is best to choose an LCD equipped with a digital DVI interface.
When will the vitality of the D-Sub analog interface end ...
In theory, DVI can get a better display effect than D-Sub, but as far as the PC signal is concerned, whether it is connected to the DVI interface or the D-Sub interface, the display effect is really difficult to distinguish with the naked eye, the author even thinks that the two The display effect of the output is "no difference". But why should we reject the D-Sub interface? Because the analog D-Sub transmission image requires a digital conversion process, sometimes it will cause picture distortion, virtual fonts or image offset, etc. At this time, only the "Auto button" equipped with the fuselage can be repaired, and if digital DVI is used In the case of interfaces, there will be no such problems.
In addition, with MicroSoft
The official release of Vista operating system, equipped with HDCP (High-bandwidth Digital Content
ProtecTIon (high-bandwidth digital content protection) function is gaining more and more attention from display manufacturers and consumers. HDCP must work under digital signals. In other words, LCDs that only provide D-Sub interface do not support HDCP function, even The LCD itself has the HDCP function, and it is only valid under the DVI interface. Connecting the D-Sub interface is invalid. Therefore, we suggest that you buy LCDs with DVI interface as much as possible. After all, the cost of adding a DVI interface is not too high, and this amount of money should be worth paying.
â— The third LCD refused to buy: Miscellaneous LCD can never be bought
As a member of the Bubble Channel LCD channel, I usually do not miss any LCD when I go to the market, so I have found and contacted many miscellaneous LCDs. These products are summed up with "seven words": poor workmanship Bad, don't think that the author is "speaking alarmistly", at least 90% of the LCD brand is such a situation, of course, these products also have some advantages, that is extremely attractive low price.
Miscellaneous LCDs are indeed cheap, but do you dare to buy them?
The price of the mainstream 17-inch LCD is about 1400 yuan, while the price of the miscellaneous 17-inch LCD is usually only 1099 yuan or even 999 yuan, but the quality of such products has great hidden dangers. Once the problem occurs, even the warranty is difficult. In addition, when buying a miscellaneous LCD, the merchant will indicate a one-year warranty or even a one-year replacement, but if this LCD fails three or four times in just one month, it also means that the buyer needs to hold this LCD frequently If the market is far away from the computer city, it will bring endless pain. Even if the chance of LCD failure is relatively small, then the face of a terrible display effect all day long may be "a tasteless food, a pity to give up" compared to the user's mood. If the user discards the miscellaneous LCD at this time and chooses the brand LCD, then the cost of going back and forth is much higher than that of buying the brand LCD directly.
The above problems are just the tip of the iceberg for the miscellaneous LCDs. For the miscellaneous LCDs, it is very likely that any malfunctions occur. Therefore, for non-brand LCD, we must be 100% refusal. In fact, the sales of Samsung Display have dominated the domestic market for 8 consecutive years, which shows that consumers are obviously more at ease with big brands.
â— The fourth LCD that refused to buy: HDMI interface
Earlier, we suggested that you buy an LCD equipped with a DVI interface, so why should you refuse the HDMI interface as a "more advanced"? First of all, we think that the HDMI interface is very likely to replace DVI as the next-generation digital interface, but from the perspective of application, HDMI is not as perfect as expected now.
The world's first LCD with HDMI interface-BenQ FP241W
I remember a few months ago, in order to test the BenQ FP241WZ, the author deliberately replaced the graphics card of the test platform with a graphics card that supports the HDMI interface, and successfully connected it to the HDMI interface provided by the monitor, but the difficult problem appeared. Under the HDMI interface, The highest resolution can only output 1920 × 1080, which can not reach the standard 1920 × 1200 of the monitor. In this way, the display area of ​​1920 × 120 is wasted in vain. Fortunately, BenQ FP241WZ supports 1: 1 output, which will not cause picture distortion (both upper and lower If there is no black border), if there is no 1: 1 "equivalent ratio" function, if the 1920 × 1080 resolution is expanded to the entire 1920 × 1200, the picture distortion will be very serious. Therefore, we believe that the LCD supporting the HDMI interface is not perfect.
Seeing that some readers may have doubts here, what is the significance of the HDMI interface provided by BenQ FP241WZ? In fact, BenQ FP241WZ provides HDMI interface not to output PC signals, but to serve entertainment terminals, such as PS3 and some videos that support HDMI interface
player. But generally speaking, very few people will buy LCD for these entertainment devices, because
Digital TV is obviously a more suitable choice. The author believes that XBOX360 and PS3 gamers "cum" PC enthusiasts can purchase BenQ FP241WZ, so this product perfectly supports 1080p under color difference (XBOX360) and HDMI interface (PS3), and it is 1: 1 output, the screen is not Will be distorted. In DVI and D-Sub mode, it can perfectly output 1920 × 1200 resolution (different modes can be switched at any time, which is very convenient).
â— The fifth LCD that refuses to buy: mirror protection LCD
It should be said that the time for the appearance of the mirror protection LCD is not short. The so-called "mirror protection", as the name implies, protects the LCD panel by adding a "protective layer" in front of the LCD panel to avoid accidental damage to the fragile LCD panel. However, in our opinion, this type of LCD is only suitable for the crowded Internet cafe market, and ordinary people are completely unnecessary.
Mirror protection can indeed protect the fragile LCD panel, but there are reflection problems
Why should we reject the LCD with mirror protection? Very simple, because all LCDs that provide mirror protection are inevitably reflective, although many manufacturers use AnTI
ReflecTIon anti-reflective glass mirror, but the effect is not as obvious as imagined, there are still obvious problems of reflection. For users who are sensitive to reflection, they may even affect their eyesight and damage their eyes. Therefore, we also have a negative attitude towards the so-called mirror-protected LCD. Of course, the Internet cafe market is a different matter.
