Hdmi help please

by Vusa360 / August 20, 2014 3:01 AM PDT

HI all.
I have finally got my computer running with a build of

Gigabyte Geforce gtx 770 windforce 3c oc 4gb
AMD FX8 8350
Gigabyte 990FXA-UD3
Corsair RM1000

And I now all the ports on the graphic card work so I thought I would connect it to my TV with a 1.4a 5m hdmi cable. I also know the port on my TV works and the cable works since I have separately tested these.
However there was no signal going through to my TV.
Does anyone have any idea on how to get it to work or any idea on why it not working?
Thanks, Dan

OK, I see 4 ports but like many cards only 2 at a time may be active. Another fine mess is that the video card setting may need to be compatible with the TV. But for me I usually can boot safe mode to get that working HOWEVER when I read your claim of all video card ports working I worry. That is, if the other than the HDMI ports are connected well, the HDMI may be inactive.

Hi Bob.
I just tried a shorter one meter cable by moving my pc out right next to the tv and it worked fine. However my 5 meter will still not work with my pc. However when I pluggede my laptop into it, the 5m hdmi cable worked fine. Any suggestions?

All that tells us is that the cable length is too long.

HDMI distances are a twitchy thing. Try other cables or HDMI extenders.

HDMI cable length will determine the quality of signal as distance is increased. You in effect proved that, so why fight it. Get another cable and QUALITY does matter here. The cheapest cable may not do well when length is involved, thus a reason for higher cost. Yes, the PC's own HDMI port electronics may help in "pushing" a signal for some distance due to its make-up but that can also degrade overtime if pushing its extremes. Alas, you may have a bad 15m cable, try flexing now and then and see if things change. Also, there are various HDMI versions out there, see link.

Today I went out and bought a new higher quality cable and it works. It still eludes me to as why my other cable works with my laptop and not my computer but nevertheless all is well now
Thank you, Dan
