电脑BIOS和GRUB阶段dp口无画面

1.问题描述

升级了主板bios后发现,电脑在启动时,显示屏黑屏,无法切换系统和修改bios选项。对于双系统主机,这影响很大。用google查询了一圈发现,这可能是nvida的固件问题导致的。Nvida的9系和10系显卡的DP1.3和DP1.4协议实现存在一定问题,开机到进入操作系统阶段会产生黑屏。

NVIDIA "Maxwell" and "Pascal" graphics architectures introduced support for modern display connectivity to keep up with the breakneck pace at which display resolutions are scaling up. The two introduce support for DisplayPort 1.4 and 1.3, however the implementation is less than perfect. Some of the newer monitors that leverage DisplayPort 1.4 or 1.3 standards don't function as designed on "Maxwell" (GeForce GTX 900 series) and "Pascal" (GeForce 10-series) graphics cards, with users reporting a range of bugs from blank screens until the operating system loads, to frozen boot sequences.[1]

2.解决办法

Nvida官方推出了显卡升级固件NVIDIA_DisplayPort_Firmware_Updater, 下载更新后可以解决问题。
