YOUR PROCESSOR (MUST) HAVE VIDEO GRAPHIC PROCESSOR INTEGRATED IN YOUR CPU
ELSE YOUR ONBOARD HDMI WON'T WORK !
OR YOU'LL NEED A GRAPHIC CARD TO INSTALL.
-ALWAYS OPEN YOUR MONITOR BEFORE STARTING.
ALSO_IF YOU HAVE A (HIGH RESOLUTION)MONITOR ,START WITH 300-600 DPI.
I had same trouble(no video),the guy installed a i7 quad but no GPU integrated in
_I use an LG 23LX1R as screen and had a black screen when I installed XP;
then I used one of these old monitor(low dpi) and been able to see.
If it can help...
