before this i use rx 470 with my dell optiplex 7010 sff (with extended pci express) it work fine...
today i buy a new motherboard and casing to switch the case, after i complete setup, there is no display on my monitor...
here the thing i already did :
8 pin connected
hdmi cable not broken (connect laptop to monitor just fine)
hdmi connect to gpu (not onboard)
already select hdmi input on monitor (still no display)
im trying put my old gtx 650 just work fine. onboard also have display
im sure 100% the cable is tight
also i notice if i use onboard or my old gtx 650, my keyboard light up when i push on button and, it have display
when i use my rx 470, there is no keyboard light up when i push on button and, "no display" (all fan is running. cooler run, case fan run, on button led light up, also rx 470 fan is running)
