Hi all any help would be appreciated on this issue.

I have a Dell U2515H physically connected via display port to a 780ti and a Sony TV physically connected to a hdmi port from the same 780ti.

The Dell is my primary monitor and the Sony TV is 'disconnected' via software in my Nvidia control panel. I occasionally game on the Sony TV and when I do I would simply re tick the box in the Nvidia panel to 'connect it' and clone the display across to the Sony TV.

When I boot however I get a completely blank screen on my dell monitor until windows has loaded in and then all is fine. Frustratingly I thought I couldn't access the bios but I have realized that the bios screen actually appears on the sony TV before the display output switches to the dell monitor for windows 10.

Is it a bios function I need to change to make the Display port the primary output?

TIA
 
Thank you for your input.

I do think the 780ti is hard wired to output to the hdmi first and then dp port second. Not a lot I can do!
