Hey guys,
I'm back with more questions!
I've recently had an issue where my on-board graphics wasn't producing any picture when in BIOS (but was working fine when installed Windows and specific driver).
My system:
(1) AMD A8-7600 (on-board R7 GPU), stock fans (not OCed)
(2) ASRock FM2A88X-ITX+ motherboard (i also tried GIGABYTE GA-F2A88XN-WIFI) -- all most recent BIOS updates
(3) G.Skill Trident RAM (2x4GB) @1600 MHz (i think clock is measured in MHz, sorry, knowledge poor)
(4) WD Green 3TB (Data), Corsair Force LS 60GB (System)
(5) Corsair CS450M PSU
(6) Windows 8.1 Pro
Apologies if some of the information is superfluous, just want to be thorough.
So here's the problem:
(1) blank picture when using only on-board graphics only (HDMI), no other output
(2) when descreet graphics (ASUS Radeon HD5450) plugged in on PCIE works perfectly, i.e. i can both get into BIOS and load the system (again via HDMI)
Asked a question here about 2 weeks ago, and got a helpful solution: use discreet GPU to install compatible GPU drivers, and onboard graphics should work. Here's link to the thread:
http://www.tomshardware.co.uk/answers/id-2370821/video-signal-issues-pcie-works-onboard-hdmi.html
This is all well, and indeed helped me get into Windows, but I want to know more information about the issue -- why it is happening, which hardware piece is the culprit, what would be the total solution if i wanted to be able to load and see BIOS settings etc.
From what i can gather, every graphics card has a basic output, which is how we are able to see into BIOS configuration screens without any drivers required. For more advanced graphics we need specialised drivers which are built on top of the OS. Is that correct?
I have a feeling it is something simple like incompatibility between motherboard and onboard GPU, but would like to know more. If anyone has any clues, any resources they could link me to -- i was unable to find anything online whatsoever -- it would be greatly appreciated.
Thanks guys!
Danny
