Amd display driver's and hdmi don't work properly.
I own exp gdc 8.5c
,graphics card 280x,500w psu by enermax ,Acer travelmate 5330.
When I install drivers they output this (problem 1 -"No amd graphics driver is installed or amd driver is not functioning properly
" )I own the paid bios setup 1.35 but It doesn't help or I can't get it to work .For some reason my graphics card is detected from amd and spins etc ,
but when I install the leatest drivers the bios version from GPU-Z is unknown it fixes itself if I install older drivers from AMD catalyst
but as I had said even if I install the catalyst driver it (fixes problem 1)but the gpu doesn't work in games also the hdmi itself.Also my hdmi for some reason doesn't work
when I plug my hdmi to external monitor at first it loads the acer logo then it freezes.Also take in mind that it happens every time even
if my hdmi is not plugged into external monitor my laptop just shows black screen I found workaround
If I disable my exp gdc and turn it on it fixes it but hdmi won't load from gpu even if I try every driver.
I've tried on diferent laptops to get it working but without success should I try to mod the bios on my laptop to unlock k whitelist or not. Once I tried to vbios my gpu on the installed catalytic driver and it worked but got the same result as problem 1 "No amd graphics driver is installed..."
