With the popularization of electronic devices such as computers and televisions, it is increasingly necessary to realize signal transmission between these devices. The DVI cable is a commonly used transmission device, and the DVI transmits digital signals, and the digital image information does not need to be converted. It will be directly transmitted to the display device, thus reducing the digital → analog → digital cumbersome conversion process, which saves time, so it is faster, effectively eliminates smear, and uses DVI for data transmission, the signal is not Attenuation, color is purer and more realistic. So how do you choose a DVI line? Which is clear DVI and HDMI?
Many people are pursuing a clearer picture quality and purchase 24+1 cable. The DVI line of computer city is not good. Many products have no logo and no brand. There are many fake 24+1 DVI 24+1 dual link cable and 2 rows in the middle. Is it false, how to distinguish between true and false 24+1 with DVI cable? Method 1: The wire diameter is larger because there are at least 25 wires inside. The fake may be only 19, the middle one is a fake wire; the second method is to use a multimeter to see if there are wires in the middle of the two cases; Method 3: buy the package with the name of the factory, the site, contact The way the regular manufacturers of products.
Which is clear, DVI able or HDMI cable? Under normal circumstances, if the display is pro or LCD TV is 30 inches and there is no built-in speaker, DVI and HDMI are similar. It is difficult to distinguish the image quality. If it is a large display device, or has a built-in speaker. The advantage of HDMI cable is very obvious. HDMI cable is more advantageous than DVI cable. The disadvantage of HDMI cable is higher cost and higher price. Under normal circumstances, the display uses DVI cable, and there is basically no HDMI interface.
The maximum resolution rate supported by the HDMI cable is higher than the DVI cable. HDMI can support all ATSCHDTV standards, not only to meet the current highest resolution 1080P resolution, but even higher resolutions currently used for commercial applications. Same support In theory, the highest resolution it can support is twice that of current HDTV;
HDMI cable anti-aging ability is stronger, DVI cord can not exceed 8 meters, otherwise it will seriously affect the picture quality, HDMI cable is generally not too much attenuation about 15 meters. HDMI is capable of transmitting audio and video at the same time, and is often used for high-definition video transmission to provide a longer transmission distance through a repeater.
