ATI DVI to Component Adapter...

[chazdraves]

Well, as it says, I guess.. I got the DVI to Component adapter straight from ATI as I figured that one goes from one high res display to another instead of trying to clean up S-Video and put it through component... The picture is really nice, so much more clear than the standard S-Video cable, but I'm having some resolution issues. It would seem (being that I only have a non-HDTV, 3-line digi comb) that the highest res this supports that my TV will do is 480i... that's all well and good, like I said - it looks great. Now with the S-Video I could do up to 1024x768 and all was well. With this dude though, if I go over 640x430... the screen is bigger than my TV and I have to pan the screen to see everything. Needless to say, this don't work well in games... Now, I can deal with 640x430 if the picture is this clear (come on, it's a friggin' TV...), but the second I load a game (namely FarCry) it automatically goes to 800x600 or 1024x768. Okay, long explenation, but my question is this... Can I a) make 1024x768 work like it used to (squish it to fit the screen) or b) force a 640x430 resolution on everything I do...? Thanks a bunch, the help is most appreciated as this is quite the bother at the moment (but boy do it look good!).

If it's worth anything too know, I'm running the 128MB 256-bit Radeon 9800Pro. Thanks again!

outputting to tv with the component adapter is much different. you may want to try getting powerstrip. btw, the tv out actually downscales whatever virtual resulution like 1024x768 to tv format (480i). 1024x768 isn't the true resolution that it is sending to the tv. hope this helps.

Yeah, it's true that it's not "true 1024" but it would look a lot better than 630x430... heh... I can set the resolutions in the display properties but then it goes off the edges of my screen, or, I can set it to 630x430 and it fits my screen but, well, it looks like crap, and surfing the web is impossible. I tried PowerStrip, though maybe I was just using it wrong, but it didn't seem like I could make that work any different... I just want 1024 shrunk to fit my screen, basically... Any ideas? Thanks...

How are you outputting via component to a non-HDTV?

How are you outputting via component to a non-HDTV?

There were alot of TV's made with component input that aren't HDTV's. Component output supports 480i, 480p and 540p...none of which are HDTV resolutions.

I'm guessing that if you don't want to run 480i resolutions, you might as well just use the s-video connection. I don't think there will be a substantial difference between s-video downsampled and output at 480i and component downsampled and output at 480i, and with s-video its already configured.

Okay, I guess 480p (and 540p, which is unused in the US AFAIK) are not HDTV resolutions (they're "Enhanced Definition"). Most people would still refer to 480p as "HDTV", though, so I was confused when he said he was using a component hookup on a non-HDTV. I didn't realize you could get displays that would do only 480i with a component input. Unless he has one of these "ED" TVs that can only do 480i and 480p -- but then wouldn't he be running in 480p?

I agree. There's also probably a way to make it scale to 480i, but I haven't tried the component out, as I have nothing to hook it up to .

480i "was" common(google YCbCr) You'll see than none of these Samsung sets support progressive scan Link but some do support component input.

Hey, you learn something every day.

 

[chazdraves]

Yeah, I have a Phillips 32" that does 480i at least. I just need more room on my screen is the big thing, I can't comfortably surf the web or anything at the default res for 480, it looks good for movies and there are no "grainies" like the S-Video, but I need to be able to scale 480i. As a note: my TV no likey progressive scan, no 480p for me. Thanks for all the info so far! Keep it coming!

You can look at the HTPC FAQ at AVSforums. I do think you are spinning your wheels however. Component 480i is only marginally better than s-video component (yes s-video is a basic form of component), and once you downsample a resolution to 480i, its not going to look like 480i does now.

Good luck though I'd like to hear how you fare.

Though it would be a great amount of info, I'm afraid that post was old enough that all the links he posted are dead...

There are some broken links, but powerstrip guides and Karnis's custom resolution guide are not broken. You can also post in the HTPC forum, it is a active forum.
