indicator of all display devices, LED display as a display device is no exception, below we have a brief explanation of the common interface:VGA input interface: The VGA interface uses the asymmetric distribution 15pin connection method, its working principle: is the video memory inside the digital format storage image (frame) signal in the RAMDAC to simulate the high frequency signal, then the output to the plasma imaging, so the

line to transmit signals. The interface is a four-pin interface. In the interface, the two pins are grounded, and the other two pins transmit the brightness and color signals respectively. Because the brightness and color signals are sent separately, the effect of the S terminal is better than that of the composite video. However, the anti-interference capability of the S terminal is weak, so the length of the S terminal line should not exceed 7 meters. 4 chromatic aberrationThe color differen

Differences between drawable-hdpi, drawable-mdpi, and drawable-ldpi: In Versions later than Android2.1, there will be three directories: drawable-mdpi, drawable-ldpi, and drawable-hdpi, these three directories are mainly used to support multi-resolution. Dpi is the abbreviation of "dot per inch". The number of dots per inch. Four types of density classification: ldpi (low), mdpi (medium), hdpi (high), and xhdpi (extra high) General screen: ldpi is 120, mdpi is 160, hdpi is 240, and xhdpi is 320.

Failure phenomenon: YOGA4 Pro (YOGA900 ISK) adopts the Type-c interface instead of the mini HDMI interface of the product, and needs to purchase TYPE-C wiring separately in the environment where the projection is needed.

　　Why do you use the HDMI cable to connect the computer to the TV? Because now the LCD TV basically has a VGA interface, so you can easily use the VGA cable to achieve the computer connected to the TV, but there is a place in the article is not mentioned, that is the resolution of the problem, now the mainstream LCD TV panel is already full HD panel (1920X1080), but unfortunately, A lot of TV (especially s

So overall, the first is the HDMI interface, followed by the DVI interface, and finally the VGA interface. First of all to determine what the LCD TV video input interface, if only VGA interface, then any one notebook can be competent; if there is a DVI or HDMI interface, then in the purchase of notebooks, we should pay attention to pick! Finally, if you want to use the fiber output audio signal, Then we sho

. Color deviation Phenomenon: The new camera installed, the result found that the quality of the display image disappointments: strange color, a nondescript feeling. Is it a partial color? Or what color is wrong? That's not good. Methods: Adjust the color-related settings in the video capture program; change the PCI/VGA Palette snoop settings; Step: Please refer to the specific software used by your camera to adjust the color-related settings in your

One of the most classic triggers for a liquid crystal display flicker is phase jitter. At present, the commonly used display signal input VGA and DVI two kinds, in which VGA is analog signal input, DVI is the digital signal (regardless of dvi-i and dvi-a). And the LCD is a digital
