+# HDMI-Tool — HDMI 源端测试工具（LT8619C/DLPC3421 转接板调试）
+
+> 更新：2026-09-03。单文件 Python GUI（`hdmi_gui.py`），另附命令行分辨率/图案工具
+> `hdmi_source.bat`。已打包版直接双击 `HDMI-Tool.exe`，无需安装 Python。
+
+---
+
+## 1. 功能总览
+
+| 功能 | 说明 |
+|---|---|
+| EDID 查看 | 枚举各显示输出口，从注册表读取 EDID 原始数据，按 EDID 1.4/CEA-861 解算：厂商/型号/尺寸/支持模式（DTD/已建立/标准/CEA-VIC）/首选时序完整参数/校验和 |
+| 分辨率切换 | 第二行"分辨率"下拉列出显卡按该屏 EDID 提供的全部模式；**应用**=临时切换（不写注册表，重启还原），**恢复**=回到本次会话切改前的模式 |
+| 测试图案 | 全屏投到所选显示器，测试卡区域可选 `640x360 / 800x600 / full 铺满`；内置 纯红/纯绿/纯蓝/棋盘格/网格线 + R/G/B 三行纯色值按钮（55/AA/FF，与 dist 下 solid_*.png 对应）+ 3 个自定义图片栏位 |
+| 命令行模式 | 自动化测试脚本可直接调用（见 §4） |
+
+## 2. 快速上手（GUI）
+
+1. 双击 `HDMI-Tool.exe`（或 `python hdmi_gui.py`，需 Python ≥3.10 + pyserial 不需要，纯标准库；自定义图片 JPG/BMP 需 Pillow）
+2. 顶部显示器下拉选择目标屏（多屏时注意别选成主屏），"刷新"重新枚举
+3. **切分辨率**：第二行选模式 → 点"应用"；测完点"恢复"
+4. **投测试图**：
+   - 先在图案按钮行右侧选**测试卡区域**（640x360 / 800x600 / full）
+   - 点图案按钮即全屏投放；按 **ESC** 退出
+   - R/G/B 三行纯色按钮（55/AA/FF）用于位交换类测试：55 与 AA 互为字节镜像对，FF 为全高基准
+   - 自定义图片：点"⚙"配置名称与图片文件（图片会复制到本目录），点栏位名投放
+5. 区域与自定义栏位配置自动保存在本目录 `pattern_slots.json`
+
+## 3. 典型场景（LT8619C demo 板测试）
+
+```
+1. HDMI 接 demo 板 → 启动 HDMI-Tool → 刷新 → 选中 demo 板显示器
+2. 分辨率切 800x600@60（demo 板 shadow EDID 首选）→ 测试卡区域选 800x600
+3. 点 R/G/B 行的纯色按钮投图 → 配合逻辑分析仪/万用表测 RGB 输出
+4. 测完"恢复"分辨率
+```
+
+## 4. 命令行模式
+
+```
+python hdmi_gui.py --dump                          控制台输出 EDID 解算（exe 版不支持）
+python hdmi_gui.py --test-pattern Blue --area 800x600 --seconds 5
+                                                   出图 5 秒自动退出
+python hdmi_gui.py --test-pattern Custom1          投自定义栏位 1
+  --area {640x360,800x600,full}  --monitor N  --seconds S
+```
+
+**hdmi_source.bat**（PowerShell 源端工具，功能与 GUI 互补）：
+
+```
+tools\hdmi_source.bat -List                        枚举显示器与支持分辨率（验证 EDID）
+tools\hdmi_source.bat -Monitor 1 -Mode 800x600     切模式
+tools\hdmi_source.bat -Mode 800x600 -Pattern -Restore
+                                                   切模式→出图案→退出后自动恢复
+```
+
+## 5. 目录内容
+
+| 文件 | 用途 |
+|---|---|
+| `HDMI-Tool.exe` | 打包好的单文件版（--noconsole；`--dump` 请用源码方式跑） |
+| `hdmi_gui.py` | 主程序源码 |
+| `build_exe.py` | 打包脚本（`python build_exe.py`，自动装 PyInstaller；`--debug` 额外出带控制台版） |
+| `hdmi_source.ps1 / .bat` | 源端分辨率/图案命令行工具 |
+| `gen_bw_patterns.py` / `gen_solid_colors.py` | 测试图生成脚本（bw 黑白系列 640x360 / solid 纯色系列 800x600） |
+| `solid_*.png` | 9 张 800x600 纯色图（R/G/B 各 55/AA/FF，供自定义栏位或脚本使用） |
+| `bw_*.png` | 5 张 640x360 黑白测试图（西门子星/频率条纹/渐变棋盘/波带/综合卡） |
+| `logos/` | 图标源文件与 `make_ico.py`（改 logo 后重跑再打包） |
+| `pattern_slots.json` | 自定义栏位 + 测试卡区域配置（运行后自动生成/更新） |
+
+## 6. 注意事项
+
+- 测试卡区域与自定义栏位配置按 exe/脚本所在目录各自保存，两份安装互不影响
+- 重打包后 Windows 图标缓存可能仍显示旧图标：`ie4uinit -show` 或改名即可
+- 多屏环境切分辨率前先确认显示器序号（下拉框中名称与 `-List` 输出一致）
+- 修改源码后重新打包前，先结束残留的 HDMI-Tool 进程（build_exe.py 会自动处理）

+<#
+.SYNOPSIS
+  HDMI 源端测试工具 —— 枚举/切换输出分辨率 + 全屏测试图案
+
+.DESCRIPTION
+  配合 LT8619C(HDMI 转 RGB888)→ DLPC3421 转接板调试使用。
+
+  原理:电脑显卡通过 HDMI DDC 读取转接板 EDID 来枚举可用分辨率,
+  本脚本调用 Win32 API 完成模式枚举与切换,再用 WinForms 全屏窗口
+  输出测试图案。板载 EDID 只声明了 640x360@60(25.2MHz 像素时钟),
+  插上 HDMI 后显卡应只能发这一个模式;-List 可直接验证 EDID 是否生效。
+
+  测试图案用途:
+    Bars      100% 彩条 —— 肉眼/示波器验证 RGB 通道顺序与极性
+    GraySteps 16 级灰阶 —— 验证 RGB888 各 bit 连通性
+    Gradient  R/G/B 三段渐变 —— 验证每通道 8bit 线性度
