Hi all,
I am experiencing the same issue however....
PG278Q
Build date January 2015
-: When i unplug my TV (Hdmi) From the back of the graphics card the ROG swift displays Post/Bios as it should.
-: My Bios is the last up to date bios which was released by asus for my board (1903)
_: Mobo/bios has the option for PCIE 2.0 or 3.0 (3.0 selected. No difference)
-: Igpu is Disabled (as best as the motherboard/bios allows via the selectable options)
_: PCIE is set to primary
-: Rog swift is display 1 TV (HDMI) is display 2 (within windows) *win7x64
-: Display 2 disabled within windows (No difference)
What i feel needs to be addressed here is two things, first been I have another monitor (BENQ XL2420T) which can be connected via display port 1.2 to replicate the same current connection setup as we have with the rog swift (DP) TV (HDMI)
If the BENQ XL2420T fail's to display post/bios, will it fail to do so when TV HDMI is also unplugged..? (For me when TV is unplugged ROG Swift works as it should as mentioned above)
I had the BENQ connected via DVI and TV via HDMI and Post/bios was always on the monitor (In windows with this connection setup TV was reported as Display 1 and monitor was Display 2, telling the OS to make the monitor primary display i never had any issues like the one were facing here.
I will test this tomorrow and report back to you all
If it does behave the same as the ROG swift then i am inclined to believe that DVI takes precedence over HDMI and HDMI takes precedence over DP 1.2 (as far as pre windows load is concerned)
If that is the case then i feel it is more a GPU Connection issue which either bios should have a true setting to tell the GPU which connection should display from "Boot" as this cannot be done via OS software as when posting, drivers/Settings are yet to be loaded. Unless the Display Driver can somehow force (DP) to be giving output ONLY when post/bios.
GPU manufacturers should test these scenario's and give some kind of option to force which port/connection should be "KING" which ideally is more a motherboard thing.
I also have a DVI to HDMI converter which i will also try to see if the signal goes to the DP or the DVI port first upon POST/BIOS.
How have asus not tested such scenarios beats the hell out of me... Or perhaps they did, which if so then whats the solution here?
Why would i ride the swing's when i've already been to DisneyLand..
