It is best to watch it in a completely black environment, because it is necessary to present black on white walls or white curtains.
Question 2: What is the resolution of the projector? General projection is divided into 800-600 and 1024*768 and 1280.
800*600 low resolution
1024*768 standard resolution (now the market is basically based on standard resolution)
1280 HD (generally, if it is a family, it is better to buy HD)
Question 3: What do you mean by projector compatible resolution? The so-called physical resolution is the actual number of light-emitting units, and 800*600 is 800 pixels horizontally and 600 pixels vertically.
Supported resolution refers to the upper limit of the acceptable resolution of the input signal. 1024*768 means that the projector can recognize the input signal of 1024*768, but the actual output is still 800*600, which means that some information is lost.
Physics 800*600, physics 1024*768 is obviously more advanced. It is possible to support the highest resolution, which is higher.
Question 4: Relationship between projector resolution and projection size Resolution has little to do with projector size. It is mainly the resolution of your film source that affects the quality of the picture you cast.
Question 5: About the resolution of notebooks and projectors. If the projector can display normally with 1024*768, its aspect ratio is 4: 3. At this time, when the notebook is displayed at the resolution of 1280*800, black edges (up and down) will appear, because the aspect ratio of the notebook display is 16: 10, but it will not affect the image.
If it doesn't look good or affect the use, you can also adjust the resolution of the notebook to 1024*768. At this time, the projection is displayed in full screen, which will not affect the display effect.
Now some projectors can automatically enlarge the image to 4: 3, but the picture is easily distorted after stretching.
I suggest you adjust the resolution to 1024*768, which is the most convenient and safe.
Question 6: About the projector, projection screen and resolution 1, the projection screen is divided into 4:3 and 16:9, and the size is fixed, regardless of the resolution.
2. 1024*768 is 4:3. 1280*800 and 1920* 1200 are16:10.1920 * 65438+.
3. Your use is commercial, at least 1024. Of course, the higher the resolution, the better, and the more detailed the picture.
4. At present, projectors have two formats: 16:9 and 4:3. If your screen is 4:3, please set the projector to 4:3.
I used to do this part of wedding projection, but now hotels are equipped with LED screens, so I put fewer and fewer wedding projections. Based on my personal experience, I can prepare a 100 inch 4:3 bracket projection screen, a 1024 resolution projector and a notebook. It is best to bring a projector bracket, so that the projector can be placed on it smoothly. It doesn't matter if it doesn't exist. You can also use a stool or chair. When playing, first estimate the distance between the projector and the projection screen to ensure that the projection screen is full. The projector is perpendicular to the center of the projection screen. Not difficult. The problems of 16:9 and 4:3 are not considered. Besides these two ratios, there are other ratios for you to choose from. Because you are indoors, don't choose the led projector.
Question 7: Why does the resolution change when the projector is plugged into the computer? What did you say?/Sorry?
1, computer projection generally has two ways, one is copying and the other is expanding. Copying is to make the projector image the same as the computer screen. Expansion is equivalent to connecting an expansion screen on the right side of the computer screen, which can display different contents.
In the way of copying, the resolution of computer and projector is the same, and the newly connected projector is set based on the default resolution of projector. The computer will automatically adapt to the resolution of the projector. When the image becomes blurred, you can adjust the focal length of the lens.
3. Self-adaptation I haven't found a way to adjust yet. If anyone below knows, learn with an open mind.
Question 8: What is the most important parameter in choosing a projector? Brightness (brightness)
resolution ratio
contrast
These are all factors that affect the image quality of the projector.
Question 9: What is the resolution of the projector? Different brands have different resolutions. There should be corresponding information and instructions in the equipment properties on the computer. It's ok if you don't search your model online.
