Default pc to sharp aquos hdmi problem

I am trying to connect my pc ( nvidia geforce gtx 560ti ) with a sharp aquos 40'' led hdtv via hdmi to hdmi cable.The pc detects the tv ( the stupid windows connection sound is made ), the tv detects the pc ( shows the resolution at the input info ) but i have no display at all! I have checked the cable with a samsung monitor, and it's ok! I have checked the tv with a hd player device also ok!
Help please!

Check the TV manual and find out what PC resolutions are supported. Usually when a display goes black, it's because the TV doesn't support whatever resolution is being sent by the computer.

If you choose one of the broadcast resolutions (720 or 1080) then you should have no troubles.

Full HD is a mystical/nonsensical term that many advertisers use to denote 1080p yet has no real meaning. Regardless of the native display - check your resolution to make sure it is one the tv supports - also check your refresh rate to make sur eit is supported as well.

Haven't used an nVidia card in some time, but wonder if you might have your display set to extended instead of clone so you're not seeing your main desktop?

@ jkkyler according to the manual the tv supports the resolution and the refresh rate is set at 50Hz...
@Isilvest am not trying to have an axtended or a clone desktop.The thing is that the card has only one hdmi port.I plug in the monitor : all fine then i unplug the monitor and plug in the tv : total black

I mentioned the extended since I didn't know if you were running a dual display. Are both the video card and tv set to 50hz? Have you tried 60hz?

@ Isilvest yeap... I 've tried all possible combinations of res. and refresh rate.
@Brian O thats the refresh rate that is given from the nVidia control panel : 50, 59, and 60 Hz. What difference does it make where i live?

He was asking because 50 Hz is a standard pal rate used in other countries, not the 60 we are used to.

Only other thing that comes to mind is to swap cards, maybe try an ATI card and at least eliminate the video card as the problem. Then you're just left with the Sharp as the problem and will need to deal with them.

If you turn off the TV and PC, connect the PC to the TV via HDMI, and turn on the TV then boot the PC, do you get anything displayed on the TV?

In North America, HDMI inputs will probably only accept standard North American video frame/refresh rates. In North America 50 Hz is not a valid video frame/refresh rate. Although your computer monitor can handle a range of refresh rates, Your TV is NOT a multi-sync computer monitor and it will not accept all the signals that your monitor can.

If you've tried all of the resolution/refresh rates without success, try sending the signal only to the TV instead of sending it to both the PC's monitor and the TV. That's what I need to do with my ATI card to send HD formats via HDMI to my TV.
