Testing HDMI output

[FlyingGnome]

Recently when hooking up my LG TV to my desktop I had some issues. The TV itself showed in the Control panel, and I could even change settings and solution. But no picture. I tried changing the HDMI input on the tv so see if anything is wrong with that one. Nothing, I can still use my PlayStation with same the input and cable, so its nothing wrong with that. My computer are fairly new, and this is only the second time I'm using the HDMI output. First time it worked with on problems. After restarting the computer several times (Without and without the TV already plugged in) Now the HDMI output won't even show under "Adjust screen resolution"
The graphic card I'm using is a "Nvidia Geforce GTX 750 Ti" and I've tried re-installing the drivers, and still nothing.
Are there any ways to test the HDMI-output in my graphic card, so I can rule out that option?

Can you try connecting your Desktop to a different TV? How long is you HDMI cable? Some components especially have issues with long HDMI cables. HDMI cables should not be longer than 10 meters for best compatibility (see http/www.hdmi.org/learningcenter/faq.aspx#45)
