诊断协议与流程

如何进行屏幕测试 (01, 02, 03)

01

准备工作

清洁显示器表面灰尘，关闭环境光自动感应，并将屏幕设置为原生分辨率与最高刷新率。

02

开始执行

进入全屏模式 (F11)，利用诊断控制栏依次切换并观察各种专业测试图案。

03

结果评估

在暗室环境下从不同视角细致观察屏幕均匀度、坏点与拖影，参考工程指南判断面板品质。

硬件架构解析

面板显示技术深度解析

专业级 IPS 面板 (In-Plane Switching)

极致色彩精准度与广视角，广泛用于专业调色显示器。暗室环境下存在轻微 IPS Glow 漏光现象。

消费/电竞 IPS (Fast IPS / Nano IPS)

专为电竞优化的超高刷新率与极速灰阶响应，但静态对比度较 VA 面板略低。

VA 面板 (Vertical Alignment)

原生 3000:1+ 超高静态对比度与纯正暗部表现，常用于曲面屏，高速运动下偶有暗部拖影。

OLED (有机发光二极管) 与 QD-OLED

像素级独立自发光，实现真正的纯黑、零拖影近乎即时响应及无穷大对比度，受自动亮度限制 (ABL) 调控。

Technical FAQs & Helpful Content

FAQ Son Surround 5.1 & 7.1

关于此项诊断工具、校准步骤及显示器技术标准所需了解的一切。

01.Can web browsers play discrete 5.1 and 7.1 multichannel surround audio?
Yes. Modern web browsers (Chrome, Edge, Safari) supporting Web Audio API can route uncompressed discrete PCM audio channels directly to multichannel soundcards and AV receivers.
02.What are the individual channels tested in a 5.1 surround sound setup?
A 5.1 setup consists of 5 full-range channels (Front Left, Center, Front Right, Surround Left, Surround Right) and 1 Low-Frequency Effects (LFE Subwoofer) channel.
03.What additional channels are added in a 7.1 surround sound system?
A 7.1 setup adds 2 Rear Surround channels (Rear Left and Rear Right) behind the listening position in addition to the standard 5.1 speaker layout.
04.Why does surround sound play in stereo when testing 5.1 in my browser?
Ensure your operating system audio settings (Windows Sound Control Panel / macOS Audio MIDI Setup) are set to '5.1 Surround' or '7.1 Surround' and that HDMI/Optical output pass-through is active.
05.What is the function of the dedicated Center channel speaker in home theater?
The Center channel delivers dialogue and on-screen vocal audio, anchoring voice signals to the center of the display screen.
06.What is the LFE (.1) channel and how is it processed by subwoofers?
The Low-Frequency Effects (LFE) channel delivers dedicated low-bass effects (10Hz to 120Hz) directly to active subwoofers without robbing power from main speakers.
07.What is virtual HRTF surround sound for headphones?
Head-Related Transfer Function (HRTF) algorithms simulate spatial 3D surround sound over standard stereo headphones by applying acoustic ear-filtering micro-delays.
08.How do I configure HDMI eARC for uncompressed 7.1 PCM surround sound?
Connect your PC or console directly to your AV Receiver via HDMI eARC, set audio output to 'Uncompressed 7.1 LPCM', and disable lossy Dolby Digital re-encoding.
09.Why does dialogue sound quiet while action explosions sound too loud in movies?
This occurs when 5.1 surround audio is downmixed to 2.0 stereo without dynamic range compression (DRC) or proper center channel dialogue gain boosting.
10.Does Web Audio API support spatial 3D audio object positioning (PannerNode)?
Yes. Web Audio API includes PannerNode and AudioListener interfaces for positioning 3D audio objects in virtual spatial coordinates around the listener.
