Cannot connect PC to HDTV with 8800GTX DVI to HDMI cable

Hello guys! I'm trying to connect my PC with a 8800GTX dual DVI card to a Panasonic TH50PZ800E TV. I have bought a DVI/HDMI cable and connected one end to the second 8800GTX DVI output and the other end to one of the HDMI inputs on the TV. So far - to image at all. Have tried running nVidia Control Center wizzards, etc. - no luck. Apparently the TV is not detected at all. I have tried a forced detection, but no luck so far. Can this be solved? Any input is appreciated.

No, it does not detect it at all. It shows as TV because I used the "Force Detection" feature provided by nVidia. Otherwise only my LCD monitor was listed.

strange. The only times i ever ran a TV on my computer it was via S-vid or VGA(D-sub).

Multi monitor with DVI(HDMI is just DVI + sound. with the 8800GTX there is not even any sound anyway) has never given an issue.

does windows allow you to extend the desktop to the tv with its own multi-monitor support?

Have you tried only connecting the HDTV? Maybe that monitor is not letting the HDTV work? LOL i'm bad with monitors. Just a suggestion tho.

Wow you make me feel like a noob for not even thinking of asking that. Worse part is i have used a SD tv for years to watch videos off my computer, so i should ask that first.

Of course I did!

Here is the story: don't ask how or why or whatever but after countless permutations in changing settings in nVidia control panel and Windows display settings and pulling the HDMI/DVI cable out and sticking it back in - a miracle has happened! - I got the 1080p desktop on my TV. No overscan, no nothing ... apparently the best aspect setting is 16:9 (and not Auto or Just). Looks quite nice. Fonts are probably not as sharp as I would like them to be, so probably there is something a bit wrong with the aspect ratio, but it's Okay for now. Utilising my HDTV to the fullest: TV, PC, X360, PS3 (these three connected to HDMI), PS2, and HDD Media player! Thank you guys for helping out ... it's a bit sad I still don't know the reason of the problem I had ... maybe a loose cable?? I really don't know.

Hello i also purchased a sony z4100 and i also am running the same setup as you with the 8800gtx. I am also having a handshake issue with my dvi-hdmi from my pc to my HDTV. For some reason i if i have the hdmi cord plugged into the the dvi slot in the back of my computer and the other end plugged into the tv, now if i try and bootup my computer i will see the initial startup screen then just after it gets passed the startup screen my screen will go blank and then my computer just stops trying to bootup and im stuck at black screen.

Now this might help you, well this how i get my computer to recognize the tv i disconnect the hdmi cord from the dvi then i bootup my computer after i hear the windows load up Noise i know my computer has fully booted up then i plug in the hdmi cord back to the dvi adapter Then magically my tv turns on and everything is working properly, just dont let your computer go to screen saver mode or else you might not be able to get your screen back unless you restart. If you are going to leave your computer on without using it for a while, i recommend putting it into sleep mode, and you shouldnt have to disconnect in order to power back up. Well hope this helps by the way I also have a panasonic and never have this issue when i plug my computer to it, and to tell you the truth ive had over 5 panasonics and never had this problem so its kind of wierd you are. And i thought it was just Sony putting out unfinished products.

Hey Guys, I'm having an issue with the similar equipment, Using a Radeon 9000 series video card from the PC DVI to my HDTV Toshiba HDMI input. My TV is recognized alone without the need for any monitors, but the problem is that everytime i reboot the computer I loose the resolution settings. Everything comes back to 800x600... AndI noticed that it was my Radeon drivers that did not boot / or were not recognized at boot up, YET... all I have to do to recognize the drivers is to go to display manager and BOOM, the drivers load and all the different display modes become available to me...

HOW do I get my Graphic card to be recognized on boot up ???? I never got that problem with S-Video.

Thank you
