How to connect the projector to a laptop

Projectors are widely used in homes, offices, schools and places of entertainment. According to the way of working, there are CRT, LCD, DLP and other types. Here is how to connect the projector to your laptop. The specific operations are as follows:

Methods / steps

Step 1: plug in the power cord for the laptop and projector first.

Step 2: then connect the video cable to the computer and the projector and, of course, plug in the audio cable of the amplifier.

Step 3: turn on the power switch of the projector and there will be a power lamp on the right. Of course, the computer has to be turned on.

Step 4: when the above instruments are ready, press the key combination at the same time: Fn F4, because different computers may have different function keys, but there are signs on the function keys, usually two screens, indicating that they can be switched between each other.

Step 5: connect successfully at this time. If the projector displays an image, but the computer is black, press Fn F4 again so that both the computer and the projector are ready.

Introduction of projector

English name: projector English name: Projector definition: an instrument that magnifies and projects an object onto a projection screen at a precise magnification to determine the shape and size of the object. Applied disciplines: mechanical engineering (first-tier discipline); optical instruments (two disciplines); optical measuring instruments (two disciplines).

Classification of projectors

1. Home theater type: characterized by a brightness of about 2000 lumens (this number continues to increase with the development of projection, high contrast). The aspect ratio of the projection picture is 16: 9, with a full range of video ports, suitable for playing movies and HDTVs, and suitable for home users.

two。 Portable business projector: a projector that weighs less than 2kg is generally defined as a business portable projector, which is as heavy as a lightweight laptop. The business portable projector has the advantages of small size, light weight and strong mobility. It is a substitute for traditional slide projectors and large and medium-sized projectors. The combination of lightweight notebook computer and business portable projector is the first choice for mobile commerce users to show mobile commerce.

3. Education conference projector: generally located in schools and enterprises, mainstream resolution, brightness of about 2000-3000 lumens, moderate weight, good heat dissipation and dust prevention, suitable for installation and short distance movement, rich functional interfaces, convenient maintenance, relatively high performance-to-price ratio, suitable for public purchase and promotion.

4. Mainstream engineering projector: compared with the mainstream ordinary projector, the engineering projector has larger projection area, farther distance and higher brightness, and generally supports multi-light bulb mode, which can better cope with large and changeable installation environment. suitable for education, media, government and other fields.

5. Professional cinema projector: this kind of projector pays more attention to stability, emphasizing low failure rate, heat dissipation performance, network function, convenience and other aspects of projector are very strong.

6. Measuring projector: this kind of projector is different from the above projectors. In the early days, it was called a contour projector. With the popularity of raster rulers, projectors are equipped with high-precision raster rulers. It is also called measuring projector (or projector, such as CPJ-3015 produced by Gaocheng Company, a well-known measuring projector in China). In order to distinguish it from the traditional projector, this kind of projector is called measuring projector.

At the end of this article, I hope it will be helpful to you.
