Okay here is my situation....

I have a ati radeon x300se with 128mb not the best but it has dvi and vga...so i went out and bought a sony 32" monitor and the sony monitor has hdmi on it only...so i went out and bought a dvi-to-hdmi cable and when i hook it up its horrible quality...there is a picture but just horrible i was wondering if anyone knows why. I know it cannot be the card because i went out and bought a higher end one just to try (nvidia 6800). If anyone knows anything about tv's is it because video cards dont support HDCP? Or whats the deal? Now im stuck using the vga its not bad...but digital is digital.

Thank you for your help guys.

I know the nvidia drivers don't support HDMI yet. They will eventually have hdmi out on the cards. For hd you can use dvi or component. ;)

Umm, HDMI is, among other minor things, basically DVI+Audio+copy protection.

DVI to HDM adapters just physically re-arrange the signal. I have a 7800GTX hooked up to a 42" Sony with HDMI and it works just fine.

Also, can you quantify horrible quality? Is this a CRT set? 4:3 or 16:9 aspect ratio?
 
I didn't say it wouldn't work ;) it's just not officially supported in their drivers yet. If it works fine, if it doesn't then don't bother them. That is how they look at it now. I do tech support for nvidia based cards and this is the official stance. Try submitting a bug report to nvidia regarding this and that is the type of reply you will get.

I think you're adding in the issue of HDCP (an inherent additional, but optional, component to HDMI), which they don't officially support. But physically the video card would have no idea if it's HDMI or DVI that it is ultimately being dumped to. There is no software support required.
 
Yeah, I have a 32" panasonic LCD connected to a Express200 onboard video with no problems other than no video card can support 1366 x 768 with 1:1 pixel. Several companies make a DVI to HDMI cable and can be found many places.

This is true, however, What I'm referring to is when you enable a high def mode in the drivers you have a dropdown that has options for component or dvi. I've seen people just plug it in and it works. I've also seen additional leg work required. Like enabling the hd resolution, then having to put it on component and then applying or dvi then applying in order to clear up the screen. I've also seen it that despite what you do it looks horrible. It seems that if one tries to submit a bug report they are told; if it works Great!!!! if not don't try to submit a bug report until it is officially supported. HDCP is not even a factor until it is required by the OS which wont happen until vista.
 
The HDTV - custom resolution/timing support on the nVidia driver is still very buggy. Sometimes it actually works until you reboot. Anyways, it's not the issue with HDMI; DVI will give you the same headache.

Thanks god we have PowerStrip.
 
That is an awesome suggestion. Powerstrip, I remember reading it was awesome for this type of stuff, Ceasar try downloading the latest version of powerstrip as he suggested it might be the answer to this problem.
 
i have tried using the dvi-to-hdmi cable that is what i get a horrid signal with...are you saying if i buy the dvi-to-hdmi ADAPTER it will make it work rather then dvi-to-hdmi?

Nope, your cable is fine. You just need to output the correct resolution/timing to match the one that your TV likes. Basically, you want the TV to display pixels at 1:1. PowerStrip is a program that can help you do just that. Its forum also has many HDTV settings that you might find helpful.
