Hi all,

Not sure how to phrase the thread topic to best portray the situation but here it goes:

I recently purchased a XFX branded nVidia nForce 630i-based motherboard with onboard Geforce 7100 graphics. It comes with HDMI, VGA, and DVI. As I understand, the HDMI also carries audio, and this was one of the drawing point for this board for use in a HTPC - which is what I intended to use it for.

Anyway, I assembled it with a E6600 processor, 2GB RAM, a 320GB hard disk, and installed Vista Ultimate on it. Everything installed fine, until I connected the it to my Samsung LCD TV via HDMI. The system recognised the TV as Samsung, and knows it when I plug/unplug the HDMI cable that connected the two. The TV too knows when the cable is plugged/unplugged... but that's about all. When the HDMI cable is connected, the configuration on the computer changes so that it displays via HDMI rather than VGA/DVI, but the TV doesn't get the signal at all and gives a error message: "No Signal" as opposed to "Check Signal Cable" when the cable is unplugged.

I've also tried installed Windows XP, but to no avail.

If anyone knows of anything else that might have caused this problem, please let me know so I can try and see if it works. I've tried various configurations, i.e. changing the refresh rate, etc. but it still doesn't work.

I am going to RMA (bought from Playtech) it tomorrow if it really is fault.

I extend my gratitude in advance for any assistance.

Are you trying to run a standard monitor as well via VGA/DVI?




Opinions are my own and not the views of my employer.

I'm trying to watch HD movie on my TV, using HDMI as the output to my TV. I've tried configuring the output on the nVidia Control Panel so that it displays only via HDMI (no VGA/DVI) but it doesn't work. I've also tried Dual View mode as well as Clone, but to no avail. TV just wouldn't show anything, but computer still believe signal passed through HDMI to the TV OK when it's not.

Does the Samsung TV actually support PC input via HDMI?

I know when I was looking around at a new TV at the start of last year that both Samsung Plasma's and LCD's both specifically mention in that manual that using the HDMI input for PC's is not supported. I even tried plugging a HDMI input from a PC into a Samsung plasma thinking there was no difference between a PC outputting HDMI and a DVD player outputting HDMI but could get no picture at all.

Failing that what resoltuion are you trying to feed to the TV via HDMI? You will need to ensure that it's a resolution and refresh rate supported by the TV.

I've tried connecting my Dell XPS m1330 via HDMI to the TV, and it worked flawlessly. :)

I've tried various settings on the nVidia Control Panel, and when I used Dual View Mode, I could see that the nVidia Control Panel automatically adjusted the resolution for the HDMI signal (which was connected to the TV) to 1280 x 720 which is acceptable for the TV. I've also tried all the three refresh available in nVidia Control Panel, but it didn't work. Cry

By the way, I've also tried unplugging the VGA/DVI cable to see it would force output via HDMI, but it still didn't work.

I'm puzzled as to why it's not working on this motherboard when it's working fine for my laptop. Both are GeForce graphics card, with the one in the Dell being a 8600M variant.

Playtech replaced the motherboard and the HDMI now works. So the HDMI was faulty in the first place.

Thanks to all who have assisted in the troubleshooting.
