1.2 Input Interfaces
(1) Two - channel HDMI2.1 FRL/TMDS with an input rate of 6GHz are provided. In FRL mode, HDMI 2.1 can support a bandwidth up to 48Gbps. The two - channel 6GHz rate enables the transmission of 4K/8K ultra - high - definition resolution and high - refresh - rate display content.
(2) Two - channel DP1.4 with an input rate of 5.4GHz is available. In the DP1.4 HBR2 mode, the single - channel rate reaches 5.4Gbps, fully sufficient to meet high - quality display demands.
(3) HDCP1.4/2.2 is supported. HDCP 1.4 supports a maximum bandwidth of 10.2Gbps, while version 2.2 supports up to 18Gbps. This allows the device to play 1080p, 4K, and 8K video content and safeguards it from illegal copying.
(4) 6/8/10/12 - bit color - depth transmission is supported. With 6 - bit color, 64 colors can be displayed, and 12 - bit color can present up to 68.7 billion colors, ensuring the high - quality imaging requirements for e - sports monitors.
1.3 Output Interfaces
(1) Supports eDP 2/4/8 - Lane HBR2. eDP serves as an interface technology for connecting monitors and graphics processors. HBR2, a data - transmission rate in eDP 1.3 and 1.4 versions, offers a data - transmission rate of 5.4Gbps per channel. Supporting 2/4/8 - Lane HBR2 means the interface can be configured with 2, 4, or 8 channels as per different bandwidth needs.
(2) Supports 8 - pair VBY@3Gbps. VBY is another high - speed serial connection technology for monitors and graphics processors. Each pair of channels can support a data - transmission rate of 3Gbps. The 8 - pair channels are extremely useful for high - resolution and high - refresh - rate display applications.
(3) Flexible expansion frequency is supported. This means the interface can adapt to different clock frequencies and data - transmission rates, catering to various display requirements, bandwidth needs, and application scenarios.
1.4 Enhanced Performance
(1) Supports 5184 - area local dimming, which can optimize the brightness and color consistency across different areas of the display device, thus achieving better panel uniformity.
(2) Response - time enhancement is supported, reducing the time it takes for the display device to show an image after receiving a signal.
(3) Supports 12/10, 10/8, 8/6 - bit dithering. This is used to simulate richer colors within a limited color - depth range, applying a dithering algorithm to enhance image quality.
(4) HDR10 and HLG are supported, providing a broader brightness and color range compared to the standard dynamic range (SDR). This enables the display device to showcase richer colors and more refined brightness changes.
(5) AMD Free Sync is supported. As an adaptive - sync technology, AMD Free Sync can effectively reduce screen tearing and stuttering, offering a smoother gaming experience.
(6) Supports Nvidia G - Sync compatible mode. Similar to AMD Free Sync, Nvidia G - Sync is a technology for Nvidia graphics cards.
(7) The MPRT function is supported. MPRT reduces the eye's persistence of vision effect by shortening the display time of each frame on the screen. This helps to decrease picture motion blur and improve picture clarity, enabling the monitor to better handle fast - moving images.
(8) Supports ambient - light control through video or audio modes. The display device can automatically adjust brightness and color according to the surrounding light, providing a more comfortable viewing experience.
1.5 Audio Output
(1) Features a built - in audio DAC digital - to - analog converter and a built - in headphone amplifier.
(2) Incorporates built - in I2S and SPDIF digital audio interfaces.
(3) Supports the mute function and fade - in/fade - out functions.

Ⅲ. Monitor Industry Information
The "Desktop Monitor Intelligence Service" report released by Omdia indicates that the global monitor market is entering a new growth phase, particularly in the high - refresh - rate e - sports monitor and smart - monitor segments. The report forecasts that the shipment volume of e - sports monitors with a refresh rate exceeding 120Hz will reach 24.7 million units in 2024 and is expected to grow to 27.4 million units by 2028.
Statistics from RUNTO show that in the first half of 2024, the overall online sales volume of monitors in the Chinese mainland market increased slightly by 0.8% to 4.95 million units. However, the sales volume of e - sports monitors surged by 30% to 2.69 million units. Monitoring data reveals that the average online market price of e - sports monitors in the first half of the year was 1242 yuan, a decrease of 231 yuan compared to the same period last year.
Among them, the 500 - 999 - yuan price range demonstrated strong growth momentum, with the market share increasing by 10 percentage points year - on - year to 48%. The entry - level price segment below 500 yuan also experienced rapid growth, with the market share rising by 5 percentage points to 9%. Moreover, due to the price reduction of e - sports monitors, high - cost - performance e - sports monitors have not only strengthened their position in the e - sports market but also successfully expanded into fields such as office and professional design, broadening their application scope.
RUNTO has found that in the first quarter, the global market share of e - sports monitors with a refresh rate of 165Hz - 240Hz reached 60.9%. In the domestic market, the sales penetration rate of 180Hz - refresh - rate monitors in the third quarter was as high as 44%, an increase of approximately 33 percentage points compared to the same period last year. This clearly demonstrates the huge market demand for high - refresh - rate and high - resolution monitors.
