Many people believe that the device interface is not of great importance. To be honest, the input and output devices were equipped with the appropriate interface configuration as early as possible. Taking the display device as an example, the resolution and refresh rate supported by the panel are generally Equipped with a matching interface specification, a 1080P resolution display, there is no need to carry an interface configuration that meets the 4K specification. Consumers do not need to make too tangled choices when choosing products.
But we need to pay attention that when the resolution of the video signal is increased, the data volume of the signal will increase. The data volume of 3,820x2,160 4K UltraHD signals sent via HDMI is about 4 times that of HD 1,920x1,080 signals. If you treat the cable as a water pipe, you need a larger water pipe than 1080p to transmit 4K signals.
The new standard HDMI ushers in an important upgrade
As early as the CES2017 exhibition, HDMI announced the new HDMI 2.1 specifications, wire speed specifications reached 48Gbps, allowing 8K/60 frames per second or 4K/120 frames per second of image data to pass. In addition, it can also bring gain to 4K TVs equipped with this interface.
· The specifications of external equipment are upgraded, which should require thicker water pipes
All players are concerned that this year's flagship-level TVs are equipped with panels with a refresh rate of up to 120Hz. While maintaining color performance, high refresh rate panels can bring a smoother picture display. As mentioned earlier, if you want to support 4K 120Hz picture transmission, HDMI 2.1 interface is a necessary condition, and equipped with HDMI 2.1 interface, it also needs to further leverage the advantages of the interface's high bandwidth throughput.
The high-refresh rate panel is a double-edged sword. We compare the high-refresh rate e-sports display. If the transition from the fast frame rate to the slow frame rate is too sudden, the effect of screen tearing will occur, so Nvidia and AMD has successively launched two technologies, G-Sync and Free-Sync, to improve this situation.
For TV products, there is a simpler and more direct way to improve this situation, which requires the use of another feature of HDMI 2.1-VRR (variable refresh rate), HDMI 2.1 higher bandwidth can transmit more The data can also "clog" more "small actions" in the data after processing by the chip.
By changing the speed of the front and back frames, and inserting frames to bring a more complete and unified picture look and feel, the new next-generation host will also be equipped with HDMI 2.1 interface, so it also supports the VRR function, and at the same time the new interface also brings ALLM (Automatic low-latency mode), further improving the feedback efficiency of the TV and external devices working together.
· "Crude water pipe" HDMI 2.1 specification changes
First of all, it is support for Dynamic HDR (Dynamic HDR), based on each scene, or even each individual frame to do HDR optimization, rather than applying a profile to the entire video.
Furthermore, gamers should be interested in Variable Refresh Rate (VRR). This function allows the data output to determine the update frequency of the output signal. If the display cooperates, the update frequency can be adjusted to the current FPS Consistently, greatly reducing the occurrence of picture tearing.
· Trinity of screen, console and transmition
Recalling the era of 1080p Full HD, Sony PS2 and xbox could not squeeze the performance of mainstream TVs at that time. After entering the 4K era, PS3 and xbox 360 are both old and stale. 4K quality game screens are for PS4 and xbox. For one, it is really stretched. It can be said that game consoles and TVs have never caught up with the weather, geography, and harmony as in 2020. The host supports 4K 120Hz TV too, and it is this wire that prevents them from blessing each other.
HDMI 2.1's higher bandwidth can transmit more data, and of course it can also support more functional signal transmission. VRR (variable refresh rate) is a function that can only be carried in high-bandwidth situations. The speed of it brings a more complete and unified picture perception. At the same time, the new interface also brings ALLM (Automatic Low Latency Mode), which further improves the feedback efficiency of the TV and external devices working together.
What I have said is very clear. These functions are prepared for game consoles. If you are an in-depth player and look forward to the launch of two new consoles, you should pay attention to the functions I mentioned above when buying TVs.
