mean when saying "I'm trying a VGA cable and an HDMI directly from the motherboard." as that is a bit unusual indeed.
Your PC should have its monitor connections either attached to the video card (for an add-on video card) or as an available connection pre-wired and soldered to the motherboard but usable from the back of the PC in the same vicinity as the rest of the PC inputs and outputs. Assuming that is what you mean here are the directions (the key being to make the physical connection then change the TV input to reflect the correct connection)-
Just put together my first computer, im pretty sure everything is hooked up correctly. I was banking on connecting it to my vizio tv and using that as the monitor.Well I can't get the signal to show up. I'm trying a VGA cable and an HDMI directly from the motherboard. Thanks for the help.
