In order to buy home theater projector in a more rigorous way, several problems are summarized, which are usually avoided by projection manufacturers and even have many false, misleading statements. So, these pits about home theater projector, you must understand.
The white walls are similar to the curtain
Contrast the white wall, the curtain can increase the gain, enlarge the Angle of view, enhance the contrast, the color is richer. For good results, a curtain is necessary (especially during the day).
Good specs means good projection effect
Brightness and resolution are indeed core parameters of popular perception, but the point is that you can't just look at them, which is why it's important to emphasize the home theater projector hardware configuration. Good foundation determines superstructure, projector is still a digital product after all, hardware must be the primary concern. Processor model, chip specification, light source type, contrast, color gamut, motion compensation, HDR, refresh rate and so on have a direct impact on the picture effect. Home theater projector with a position of $700 is mostly equipped with a display chip of 0.47DMD, a resolution of 1080p, and a number of processor models, followed by Mstar6A938>Mstar6A848>Amlogic T968.
The Angle of projection has nothing to do with picture quality
Certain projection angle is reasonable, through the right and left trapezoidal correction of the deformation of the screen to pull, the advantage is convenient, correction sensitivity is also very important. But the effect has a certain sacrifice, and the side cast Angle is proportional. The greater the Angle of side cast, the greater the influence on the picture.
Motion compensation MEMC is useless
Some professionals say that sports compensation is useless, making people doubt his professionalism. Say a little commonly, without motion compensation, the picture that sees high motion can have apparent drag shadow, say to be chicken rib unexpectedly? In terms of professional terms: motion compensation, referred to as MEMC, is a motion picture quality compensation technology used in television. The principle is to use dynamic image system and insert a motion compensation frame between the traditional two images, so as to improve the 25p/s of the ordinary TV signal to 50p/s. In this way, the moving picture is more clear and smooth, which is better than the normal response effect. In this way, the residual image of the previous frame can be cleared, the dynamic sharpness can be improved, and the image can be dragged down to a level that is difficult for human eyes to perceive. So, don't say that motion compensation is useless.
