症状

Precision T5810 would not show any video during boot when 2 monitors were connected via DVI and using DP- DVI dongles.

The customer would also get an error message on screen stating "Out of Range signal Cannot display this video mode Change computer display input to 1600x1200 @ 60hz"

2 monitors connected were 2007WFP with a maximum resolution of 1600x1200 @ 60 Hz

If 1 monitor was connected, video is shown during boot.

原因

解决方案

There is a mode, on FirePro graphics cards, called SST - Single Select Timing and on our 14.xxx drivers that is enabled.

When two passive adapters, DP to DVI, are used and identical displays are attached which don't run higher than 1280x1024 res then SST remains enabled and as a result there is no display on boot into Windows. If an active adapter is used alongside a passive adapter then SST is disabled and system boots with Windows displayed correctly.

This should be resolved in the new AMD driver 15.201
