NVIDIA Graphics Firmware Update Tool for DisplayPort 1.3 and 1.4 Displays

Temporary solution

先用DP转HDMI接口连接，安装好驱动，再换回DP NVIDIA RTX / Quadro Desktop and Notebook Driver Release 470 R470 U18 (475.14) | Windows 11

Curative treatment (Experimental)

Update GOP

Step

1. Backup VBIOS

nvflashk: Flash (almost) any vBIOS to (almost) any nVIDIA GPU - GitHub

./nvflashk.exe --save original.rom

2. Update GOP of VBIOS

GOP_Updater_v1.9.6.5.k_mod_v0.5.2 - pCloud

将original.rom直接拖放到GOPupd.bat上，生成xxx_updGOP.rom

3. Flash VBOIS

./nvflashk.exe --list -L log.txt # 确认显示适配器编号
# -L 将执行日志输出到文件，解决运行结果一闪而过的问题

./nvflashk.exe --check -L log.txt # 检查显卡bios芯片的容量大小

./nvflashk.exe --protectoff -L log.txt # 关闭写入保护，解决报错：EEPROM erase failed. Software write protection enabled.

./nvflashk.exe --index=0 xxx_updGOP.rom -L log.txt

2. AMD and Nvidia GOP update (No requests, DIY) - BIOS/UEFI Modding / BIOS Modding Guides and Problems - Win-Raid Forum

Result

刷入更新了GOP的VBIOS后，仍旧黑屏，没有效果

FAQ

1. 刷入报错

./nvflash.exe --index=0 xxx_updGOP.rom -L log.txt
# ERROR: Falcon reset control is disallowed! A system restart might be required before running the utility.

Reason

nvflash版本太高

Solution

改用低版本nvflash_5.190.0.1，但仍出现新报错

# EEPROM erase failed. Software write protection enabled.

改用 nvflashk

2. Windows分辨率设置没有4k选项？

NVDIA 控制面板 => 更改分辨率 => 自定义 => 创建自定义分辨率 => 水平像素3840，垂直扫描线2160 => 勾选应用

3. 应当支持10bit色深，但系统位深度显示为8位？

NVDIA 控制面板 => 更改分辨率 => 使用 NVDIA 颜色设置 => 输出颜色深度 10 bpc
