楼主
4K启动屏幕一直很麻烦,因为原来的“Mac版”EFI不支持DisplayPort 1.2。我在DP1.2模式下的戴尔U2515H也不会显示任何东西,虽然它只是WQHD。另一方面,当通过HDMI 1.4或DP 1.1连接时,4K启动屏幕可在HD 7xxx或Kepler GPU上工作(在这种情况下显然不是60Hz)。
RTX UEFI驱动程序肯定会支持DP 1.2。
这个是机翻,还是能看懂的,跟我实际测试的情况一样,相当蛋痛
所以我目前要4k 单dp线连4k显示器启动,要么用不支持boot启动的显卡,要么用支持boot启动的显卡,先用hdmi或者dvi启动出来画面后,换单dp线
4K boot screens have been troublesome, because the original "Mac Edition" EFIs didn't support DisplayPort 1.2. My Dell U2515H in DP1.2 mode won't show anything either, although it's just WQHD. On the other hand, 4K boot screens do work on HD 7xxx or Kepler GPUs when connected by HDMI 1.4 or DP 1.1 (obviously not 60Hz in this case).
The RTX UEFI drivers will surely support DP 1.2.
