HDMI 2.1 standard met us at the CES exhibition in early 2017. This new interface protocol with bandwidth up to 48Gbps supports up to 10K/24Hz movie screen display.
At the same time, the latest RTX 30 series graphics card has natively supported HDMI 2.1, and AMD RDNA2 RX 6000 series graphics cards are also expected to be added, but there are still too few display products that support this specification, and they can even be described as none.
In fact, the software strength and hardware configuration of the monitor products are always inferior to those of the same positioned TV products. For example, the dynamic backlighting of the "e-sports monitor" product, the stability of the high refresh rate picture, and the built-in picture quality processing chip are not as good as that of the TV. When the TV is focusing on the gaming field, it is difficult for me to think of any other temptation of the monitor.

The importance of a line is far beyond your imagination
you may not believe it. Now many high-brush products on the market that also have high-resolution attributes are not useful for half a cent. The crux of the problem is that there is no interface with the specifications to match it. The data throughput of
DP1.4 does not support 4K+144Hz. It needs to be implemented through DSC technology, but the output image quality will be damaged.
· DSC: It can be understood as a video 'block cutting' encoding technology, which is calculated by the graphics card and then presented by the monitor equipped with this protocol.
As early as 2018, Dell launched a display product with an 8K resolution, but this product obviously does not meet the technical support capabilities at that time. 8K resolution requires greater data throughput to support it. The mainstream specifications of the display interface are still in the period of DP 1.2a1.4b and HDMI 1.4a/b2.0a. Due to the interface data throughput limitation, 8K resolution displays obviously have no meaning.
8K display, let alone whether the eyes will be "blind" when they are too close to each other. Just say that this interface is not good, 8K is meaningless...
When the resolution of the video signal is increased, the amount of data of the signal will increase. The data volume of the 3,820x2,160 4K UltraHD signal sent over HDMI is approximately 4 times that of the HD 1,920x1,080 signal. If you think of the cable as a water pipe, you need a water pipe larger than 1080p to transmit a 4K signal. This may have more links that affect the final picture than you think.
is standard in the future. What is the necessity of HDMI 2.1?
All players are paying attention to this year's flagship TVs are equipped with panels with refresh rates up to 120Hz. While maintaining color performance, the high refresh rate panel can bring a smoother picture display effect.
As mentioned earlier, if you want to support 4K120Hz picture transmission, the HDMI 2.1 interface is a necessary condition. It is equipped with the HDMI 2.1 interface, and the advantages of high data throughput of the interface are also needed to further utilize.
At the same time, the HDMI 2.1 interface is obviously not just about improving resolution and refresh rate. The high refresh rate panel is a double-edged sword. We are analogous to the high refresh rate e-sports monitor. If the transition of fast frame rate to slow frame rate screens is too sudden, the screen tearing effect will occur. Therefore, Nvidia and AMD have successively launched two technologies: G-Sync and Free-Sync to improve this situation.
can support more additional functions (a.b.c.d represents different specifications and solutions)
. For TV products, there are simpler and more direct ways to improve this situation. This requires the use of another feature of HDMI 2.1 - VRR (variable refresh rate). HDMI 2.1's higher bandwidth can transmit more data, which can "swallow" more chip processing "small actions" in the data.
Currently, there are too few monitors with dynamic backlight, so the black field of the monitor is generally poor
20 flagship TVs generally have begun to support the installation of HDMI 2.1 interface specifications. Among Sony, Samsung , Hisense , and LG, all have already appeared 4K (UHD) + 120Hz + HDMI 2.1 + VRR (variable refresh rate) + HDR ( high dynamic lighting rendering ) + ALLM (automatic low latency) and other ultra-standard products have appeared. It is even rumored that Korean TV manufacturers are considering dual-supported TV products of G-Sync and Free Sync.
This thing is indeed an OLED "monitor", but are you serious about 55 inches 34999? Isn't it nice to buy a 55-inch OLED TV?
If nothing unexpected happens, products that support these specifications will use OLED panels. In fact, the author does not need to say much about the improvement of OLED games. Just the advantage of OLED panels makes the monitors far behind. There is no real OLED display on the market.
1/3 price, 1/1 happiness, well, it’s so delicious!
Of course, there is another advantage in TVs, that is, "bigger and cheaper!" 4K60Hz is almost the starting standard for TVs nowadays. For example, Redmi TV is 98 inches. Is it 4K60Hz or 98 inches? If you play games in 98 inches, you can kill them in seconds! Just 19,999 yuan.
Of course, the effect of Redmi 90-inch TV may be really worse, but it is big, it is big, it is big, ah..., and do you know how much does a 65-inch 4K60Hz TV cost now? The cheapest ones cost less than 3,000 yuan.
big! This is the kingly way...
When both the RTX30 series products and Sony PS5/Microsoft XSX claimed to support the display capabilities of "4K+N", the current display products are indeed a bit stretched. Perhaps changing to a stronger TV is the better choice. The size ratio, price, and even the absolute crushing of screen material and display technology. It may take some time for the display products to "respect" their hard power.
