Help with HDCP - Blu-ray Forum

dankhar · 07-23-2007, 12:27 AM

Well, I have been wanting to use the HDMI cable with the PC for a long while now, and I finally got a DVI to HDMI connection going, but when I hook the HDMI connection to my TV it sees that there is something there but it doesn't find the signal.

So anyone have any hints? Maybe I am doing something wrong? If you could help me out I would appreciate it. Thanks in advance.

You don't need HDCP if you're just using an HDTV as a monitor*, unless you're playing Blu-ray on your PC with a HDCP-compliant video card and HDTV.

*=I'm not 100% sure on that, though. Your HDTV **MIGHT** need an HDCP-compliant video card to make that "handshake' when using the HDMI cable.

But I don't see why you need HDCP when HDMi is just DVI from your PC.

Hmm, well I am using a HDCP Compliant card and I have a monster DVI attached to the card with the HDMI Cable hooked from that to the TV. I cannot get a signal when windows is loaded. But when I restart the computer, I can see the BIOS and all boot screens fine. But as soon as windows gets to the log on screen, the signal is lost.

I read into it a bit but nothing is helping.

I am running Windows Vista Basic at the moment and a Samsung DLP TV. I am thinking this may be a problem with the TV or maybe just a resolution problem. But I work for Sony and use many of the TVs we have to test this same setup like I have here, and it works on all of our Rear Projections LCDs and our Flat Panel TVs.

This is going to bug me to no end. :\

Any help is appreciated thanks in advance.

I think you may have an incorrect resolution. Set you video card to 800 x 600 or something similar and see if that works. If so work up from there. If you video card has multiple outputs, set it only to output out one output.

Try to match your TV's native res (usually 16:9 720p or 1080p).

Thanks for the help guys. For some reason I had the cable hooked up and it never detected it but when I re-installed the same driver version I always had on here it finally noticed the cable. It plays my blu-ray movies now without a stutter like it did when I was using my VGA hook-up. Now the only thing I need to do is figure out how to make the damn thing show my start menu and such. It has a cutoff around the screen the size of the start menu. If you have any ideas on how to fix that it would help. I know there has to be some way to fix it.

Thanks for all the help guys.
