So basically, I just built my new computer. I managed to solved all problems except one, HDMI handshake problem. This problem has been driving me insane. I desperately need help. GPU - XFX/AMD Radeon HD6770 ZNLC with DVI/VGA/HDMI Monitor - HP 23 inch LED Monitor Situation #1 Have HDMI plugged into the monitor and the graphic card. Confirmed connection is firmed. Powered up the monitor and the PC. Display works fine except when I power off the monitor and turn it back on. HDMI and DVI no longer feed signal. Needs to completely power off the PC and Monitor. Turn them back on to get HDMI signal again. Situation #2 Have HDMI and DVI both plugged into the monitor. Confirmed connections are firmed. Powered up the monitor and the PC. PC correctly detected two connections. When DVI connection was removed HDMI no longer feeds signal. When monitor powerd off then on again no HDMI signal was captured. A complete PC shutdown is required to get DVI and HDMI to feed signal again. Situation #3 Have DVI plugged into the monitor. Did not experience any handshake problem at all. Any solutions?
