Most mainstream manufacturers do not integrate HDMI ports on their own graphics cards after careful consideration. The main reasons are as follows:
1. Give users more choices.
If the user chooses a native HDMI graphics card, then his device has almost no choice but to choose a display with an HDMI interface, and now only a few manufacturers such as BenQ have launched an LCD display with an HDMI interface on the market , and are expensive. Therefore, the graphics card using the native HDMI interface has virtually increased the purchase cost of the user, and has become a "forced" user in disguise.
2. DVI interface monitors are still the mainstream in the market.
As the saying goes, it's hard for a clever woman to cook without rice. The interfaces used by the LCD monitors that can be seen on the market are almost all DVI interfaces. It is difficult to directly connect an HDMI interface to another HDMI interface. Moreover, if the user is using a native HDMI graphics card, after connecting it to a DVI monitor, there will likely be black and white, full white to unrecognizable, etc., and the user must adjust the brightness of the monitor to solve the problem. In a normal scene, doing so may cause the scene brightness to be too low to watch, and the user may need to constantly adjust the brightness. It is also for this reason that before the large-scale emergence of HDMI interface displays, most manufacturers have taken a very cautious attitude towards the direct integration of HDMI interfaces in graphics cards in order to ensure the imaging quality of high-definition video.
