Any benefit over component by using HDMI (PS3) to DVI (TV) cabling?

Cheers.

I think the most appropriate forum for that is the AV Forums for your answer.

The short answer here is that HDMI>DVI in every respect, however depending on your set up you may not actually see a difference. In terms of sound, HDMI also will carry your digital 5.1 sound the same way optical does but obviously you need HDMI capable sound equipment in order to us this feature.

You say your considering using a HDMI to DVI convertor? I wouldnt bother, conversion such as this will always see a degradation in quality - I would stick with component and your optical cable, you still get HD quality and digital 5.1

Like Alfonse said, AVforums can give you much more detailed information.

Thanks all especially Ritchie. I'll tell him to save his money and stick with component / optical.

Sorry csiman, I forgot to point out, with HDMI he will get 1080p quality picture, at the moment he will only have 1080i with his component cables but in my experience the difference is again negligible, also you need a 1080p capable TV to take advantage of this.

I'm not sure if he would still get 1080p if he put a HDMI cable into a DVI convertor, as I am led to beleive DVI is not 1080p capable and I also suspect most TV's will not accept 1080p through anything other than a HDMI port.

In any case, without a HDMI port on his telly your mate is still better off with component. ;)

Apologies if I've confused you!

just about still with you. Thanks for your effort and time.

There's a problem with using component cables with the PS3 in that Sony, in their infinite DRM-filled wisdom, have decided to cripple the video output via component when being used with DVD's or Bluray disks.

It appears to be downscaling them to what looks like 480i! (note that your device will still say it's connected at 720p/1080p etc, but the quality is *drastically* lower) Using HDMI avoids this and allows full-quality DVD and Bluray output.

Please note that what the poster above said isn't correct - the video portion of HDMI and DVI are identical, so if your friend has a DVI input then a simple HDMI->DVI adapter will do fine, should be able to pick one up for £5 or so. Note that there's no conversion taking place - it's simply a different connector mechanically. DVI also supports HDCP (copy protection standard) so you'll not get any artificial quality degradation on DVD and Bluray output.

Sadly DVI doesn't support audio, so you'll need to use the optical output for that still.

Thanks for clearing up my mistake there, LOL

I did not suffer the 480i video output when using component that you described, is this prevalent on newer models only?

It manifested itself on a launch 60gb PS3 with the latest firmware (well, latest as of a month ago, I think there's a new one out this week) - google research confirms i'm not the only one that's seen it. I can't confirm that it's going to exactly 480i for bluray, but it looks poor enough that it seems to be around there. The difference between the component output and HDMI at 720p24/1080p24 is *VAST*.

If you look on the PS3 options for DVD it mentions specifically about the downgrading on DVD output around the upscaling option (you might have to select to upscale, with component video cable connected before you get the message); but there's nothing about the bluray crippling at all.

I had a 40GB and only ever used Blu Ray, I probably would not have had that problem then.
