Guida all'acquisto del monitor 4K: Come scegliere il monitor giusto

市场上充斥着许多知名品牌的4K显示器；它们都有自己独特的特点和规格。对于买家来说，特别是对于新手来说，选择合适的显示器变得困难，因为围绕着它们有许多技术术语。设计可能乍一看很吸引人，但它们可能具有较低的特性评级，因此在做出如此重大的投资时需要保持谨慎。在最终选择时，重要的是更加关注您的需求和预算。下面的文章可以帮助您了解一些您需要在新产品中搜索的主要功能。

购买4K显示器之前要考虑的事项：

1. 显示器尺寸：

越大越好！但是您必须有足够的空间；而且它也会更贵。显示器尺寸通常是根据其长度对角线测量的。规格通常以纵横比来说明，如果您在生命的任何阶段学过代数和几何学，那么您肯定可以根据给定的纵横比计算出显示器的高度和宽度。请注意，1：1的纵横比将导致更近距离的视图，直接落在视线中，但较大的单位将具有更高的纵横比。

2. 显示器类型：

如果您走向市场，您会发现与显示器类型相关的三个术语，当然它们很容易混淆初学者。4K显示器分为三种类型：TN、IGZO和IPS类型。每种类型都有其独特的优点和缺点。以下是一些详细信息：

TN面板：

Questi sono consigliati per i principianti grazie alle caratteristiche semplici e alla gamma di prezzi conveniente. Tuttavia, puoi aspettarti che forniscano tempi di risposta rapidi, ma gli utenti devono fare compromessi per l'accuratezza del colore nelle immagini.

Pannelli IPS:

This selection improves performance in terms of image sharpness and color reproduction. If you are a gamer or love to do video animation then you may find it little slow for your expectations. Note that, TN displays offer response time rating of 1 millisecond whereas IPS stops at 4 millisecond level. p>

IGZO Panels: p>

IGZO panels are able to deliver high power service due to their improved transistor based design. At the same time, these panels use to have lower physical mass but they stay always ready to consume more energy with high power delivery. p>

While buying a new panel for your 4K needs, it is goo to check for processing power and graphic card details; but the best decision will be made on the basis of your budget. p>

3. Color Accuracy: p>

Technologies are taking over each other day by day; with this advancement several features are being improved but few are also getting worst like colour gamut of new monitors as compared to the old ones. It is essential to have higher colour accuracy for 4K videos because better colours lead to decent information delivery. Monitors or PCs from several years are following standard RGB pattern for color adjustments where sRGB is considered as best for full coverage with precise color delivery; you may find Adobe RGB little complicated as its range doesn’t suit to human eye. p>

The term color accuracy deals with the system’s ability to deliver required level of hue instead of making rough calculations for its delivery. When color gets deviated from its actual fidelity level then this error is represented with a Delta E figure, note that it is essential to have lower value of delta E value that reflects good color delivery. The best recommendation is 1.0. p>

4. Refres h Rate:

Essa in liv pou vokabiler pou bezwen ou yo nan achte yon monitè 4k. Manifakti fè monitè ak taux refres ki varye pou aplikasyon varyab; pou egzanp, monitè pou jwe yo itilize taux refres 144Hz, pifò nan moun yo k ap itilize yo desann yon ti kras ak nòt 60Hz, pandan ke pifò nan ekran 4K yo gen yon taux refres 30Hz. Li vin yon ti kras difisil pou jere bezwen edit video ak imaj nan 30Hz paske li fè manipilasyon fenèt ak sourit ti kras complike ak vitès tounen, men wi, yon opsyon 60Hz pi bon pou varye vitès ouvle yo; ou kapab ale pi wo pase sa tou.

5. Aspect Ratio:

It is the ratio of length with respect to height of the display screen. One of the most popularly used aspect ratio setting is 16:9 that delivers great results for games and movies. In case if you are a serious hardcode gamer then you may find 21:9 aspect ratio more suitable; this range is available for few gaming special monitors. With 16:10 rating, you can enjoy more vertical space and it suits better when users need to work upon numbers of images and documents.

6. Brightness:

Most of the high end monitors are designed to offer brightness rating somewhere around 300 or 350 cd/m2. In case if you work in a much brighter room then you can easily handle higher brightness ranges for your monitor but note that this higher rating causes more strain to your eyes. The most suitable and professional recommended brightness range is 250 cd/m2.

7. Contrast Ratio:

It shows the different between brightest and darkest reflection on your screen. It is always advised to buy monitors that offer higher contrast ratio because this higher rating means much better differentiation between brighter and darker scenes. However, all manufacturers prefer to add different contrast ratio parameters to their products without following any standard for this rating so you cannot make more analysis for this feature.

8. Response Time:

The time taken by a pixel to change its color is measured in terms of response time. Most of the old display screens used to suffer with ghost effect that occurs due to very slow response time when pixels are not able to work in synchronization with moving frames. But all the recent designs offer improvement over response time with a valuable range of 1 to 4 ms.

9. Conn:

It is essential to take a wise decision about getting certified display cables for your monitors but few popular manufacturers these days are also offering uncertified DP cables. These uncertified cables lead to so many troubles; one of the most common is that they make connection with pin 20 and reflects unwanted voltage back to the system- causing big damage. Also, the uncertified cables lead to bandwidth losses where 4K display cannot function well even at 60Hz rating and improper cables cause reduction in refresh rates. The idea is to get a 4K monitor with 4K HDMI support but it must be supported by your graphic card as well as monitor. The USB hubs are also essential options and they offer higher speed rating too.

10.WS:

Here is one more essential consideration for buying 4K monitors and it is named as DPI, desktop or window scaling. Generally, PCs are designed with higher pixel densities; it helps to improve size of menus and windows that enhances readability. Note that, window scaling not always effect all applications on your device so if you have few commonly used app collections in this category then you may not find it as useful.

11.Viewing Angle:

Generally, the term viewing angle is related to TV screens but in case if you want to enjoy videos on your computer with your friends around then you must have higher viewing angle setting for better results. Prefer to keep it above 170 degree.

12.G-Sync or FreeSync:

Gamers need to focus on these two parameters; collectively they are well known as adaptive sync. These settings improve system performance over screen tearing issue, graphic mismatch problems and refresh rate mismatches. The screen tearing problem use to affect gamers when they switch to fast paced games as monitor refresh rate cannot stay in synchronization with the output of graphic card. This effect is quite annoying but thanks to adaptive synch technology that leads to better displays with improved synchronization. Note that, you cannot find a monitor that has both FreeSync and G-Sync technology. Adaptive sync is useful for adjustment of frames and shutter speeds.

Bonus for Great 4K Monitor:

1. Support Hardware Calibration:

Professionals always need perfect performance from their monitors because they do not have any space for making compromises for quality. You need to make efforts for selection of finest backlights and LCD panels; prefer to run calibration tests before buying your new monitor.

2. Compensazione del retroilluminazione:

Molti monitor in questi giorni hanno anche la capacità di compensazione della retroilluminazione che porta a regolazioni di colore e impostazioni di luminosità dello schermo di display. Quando i monitor non hanno la funzione di compensazione della retroilluminazione allora naturalmente forniscono rapporti di contrasto molto migliori. I professionisti devono iniziare la ricerca di perfezione tono per ottenere i migliori risultati.
