Why my hdmi cable keeps saying unsupported signal. check your device output

I have a jvc television but I bought a stand F-2100 universal remote, how do I operate the remote

Hi Tejinder,

There is a lot of variation in the HDMI cables available in the market. I also faced the same problem with an LG LCD and a Sony play station. I had an HDMI cord which I got with the HDMI converter fro the US, solved the problem. The other cords are working fine with the HDMI converter. I hope it helps.

Good Luck.

try only having the hdmi cable hooked up to ps3 and tv, turn off ps3 and hold power button for 5 or 10 seconds and you should hear 3 beeps, this should reset the ps3 and detect the settings, if this doesnt work you mmay have to manually change audio and video settings in the ps3 settings menu to hdmi output and auto detect which settings work.

double check your HDMI cable and connectors and make sure that they are properly connected. try to replace your AV & HDMI cables

You will have to set the resolution of the TV to equal the PS3 or it won't work.

it sounds like the resolution the laptop is trying to send is not one of the resolutions that the television can display. TVs can display a range of resolutions, so try changing the laptop resolution, either increasing it (make the pixels smaller) or lower the resolution, try a variety of resolutions, one should work.

mine is got the red light flashin to yellow.it just started doing it tonight

try the connection help option on the xbox..they all have it

The problem is that, according to the specs for that TV, it doesn't support 1080p.
That's a 720p television you've got. (Specs here)
While the specs say that it supports 1080p, the resolution says it supports 1366 x 768, which is only 720p, not 1080p or even 1080i.
You may want to contact Sony for clarification, because their specs for that tv are contradicting each other.
