Personal hobby: How big should the monitor for PS image processing and audio-visual video production be?

The bigger the better, the higher the resolution.

First of all, we need to know what conditions the display needs to be suitable for video editing and PS retouching. Only when you know the selection criteria can you choose a monitor that suits you.

Color accuracy: whether it is video editing or PS retouching, the color of the display must be accurate, which can truly restore the color of the actual object, and the color will not deviate too much when outputting. The color standard of the display is expressed by DeltaE. The smaller the value, the more accurate the color is. At present, the color scale of better displays on the market can be around 3, and the color scale of professional photographic displays can be within 2. Therefore, if you are doing serious video editing and PS retouching, you can choose a professional monitor with a color scale of DeltaE≤2.

Color gamut: If PS retouching involves printout, you must choose a display that covers Adobe's wide color gamut, so that the color of the photo can be consistent with the color on the screen when printing. If the work is only uploaded to the network, select the screen of 100%sRGB (it is not excluded that the work will be printed in the future, so the wide color gamut of AdobeRGB will be used). Video editing depends on whether the display supports DCI-P3 color gamut. DCI-P3 color gamut is a relatively new color standard applied to digital cinema at present, which pays attention to people's visual experience and matches all the color requirements that can be expressed in movies as much as possible. It can also be called the film-level color gamut standard. Therefore, if there are a variety of needs, you can choose a professional display covering a variety of color gamut to meet different application needs.

Color depth: color depth (gray scale) reflects whether the transition of two colors before and after each point on the screen is smooth, and the number of colors is expressed in bits. The larger the value, the more uniform the color transition. High-end cameras usually have a shooting format of 10bit422 to choose from when shooting video, where 10bit refers to the color depth. Compared with 8bit, 10bit video will have richer color types and more natural color transition. Similarly, the 10bit display can present more kinds of colors, with uniform color transition and no fault, which provides more post-processing space for photographers. At present, ordinary cameras can take photos with the color depth of 10bit, 12bit or even 14bit, and then use a 6bit or 8bit display to process the photos, which feels a little stretched.

Size and resolution: Video editors recommend using a monitor with 4K resolution. At present, mainstream shooting equipment supports shooting 4K video. The 4K resolution screen can watch 4K video material in real time, and PS retouching can show more details. A suitable size is 27 or 32 inches. If it is less than 27 inches, the ultra-high resolution will cause the words on the screen to be very small, and the eyes will be tired after watching it for a long time.

Summary:

1, color scale delta ≤ 2;

2. Color gamut covers AdobeRGB, sRGB, DCI-P3 and other color modes;

3. The color depth is 10 bit;

4. The resolution is 4K, 27 inches or 32 inches.

Therefore, the video clip and PS retouching display mainly depends on the above standards. After understanding these selection criteria, subjects can easily choose a monitor that suits them. At present, there are not many professional monitors that meet these standards on the market, and the price is very high. In addition to Zhuo Yi's NEC and other brands, Bengjia's SW series is also a good choice and can meet the above selection criteria. Prices range from 3K to 1W, and there is always one that meets the requirements of the subject. Moreover, BenQ SW series professional photographic monitors were used by the judges of the 27th National Photographic Art Exhibition and recognized by many professional photographers. SW series also supports hardware color correction, and the color accuracy will be longer than that of ordinary monitors. It is also equipped with a hood, SD card slot and Type-C interface, which can effectively improve work efficiency.
