HDMI not working on my test boot? Tags: Homebuilt Monitors HDMI Systems Last response: August 1, 2012 1:33 AM in Systems Share xogecko August 1, 2012 1:22:06 AM I connected an HDMI cable to the monitor and the video card but keep getting a no signal on my monitor when test booting. The Gtx's fans spin fine, so does the Cpu's heatsink fan. Any help on this? (I tested the HDMI cable with my laptop, it works just fine.) Does this mean that the HDMI port of my GTX 670 is faulty or drivers? I haven't completely wired everything. I'm just trying to test boot up to the BIOS error screen. Following things are attached: GTX 680 card on an ASROCK Z68 Extreme Gen3 i-5 2500k Heat sink with fan. 2 Ram sticks Power is only currently given to the GPU card and the motherboard itself.
