Need help with setting 480i
Tinydane:
Hey everyone..I'm new to the forums here and new to arcade building as well. I"m working on my first arcade built with a mameroom UAII kit. I have a 27" ILO SDTV that has an svideo, composite, and component inputs. The pc I'm using is P4 Dell and has a Radeon X300 video card in it.
The X300 has svideo out as well as DVI out. I had first intended to use the svideo for the arcade gaming but after getting it hooked up and running some games there is a lot of blurry, shifting sort of look to much of the graphics. So my next step was to try to use the component inputs. To do this i picked up a DVI to RCA cable thinking that would do the trick.
Using that input though the tv isnt recognizing the signal on the component input. The only thing I can deduce is that it being an SDTV the max resolution it can recieve/dipslay is 480i not anything above that progressive.
Does anyone know if there's a way with the radeon x300 to force it to send a 480i signal? And if not can someone recommend maybe a substitute video card that would work with this setup?
Thanks in advance for the assistance.

Not very familiar with ATI, but this is what I know about NVidia. I recently purchased a BFGTech 9400 GT card from Fry's, which has a breakout cable that splits to component, which I think is the best input for 480i. The NVidia software contains a wizard to detect the settings for output to a TV. I set mine up as a second monitor first, then made it the primary once I got it configured.
Does your DVI to RCA cable have Red White and Yellow jacks? If so then that is Audio (Red and White) and video (Yellow). That will not connect to the component input. Component inputs are video only and would be Red, Green & Blue.
Eversynth:
Have you tried forcing TV detection in the catalyst control center? It should allow you to gain access to various interlaced resolutions.
Or you could use some software solution to add an interlaced resolution, such as powerstrip.

My DVI to RCA cable has the red green blue (component) breakout as I wished.
I actually got an aswer from the avs forum guys. Turns out that video card I have (Radeon X300) outputs DVI-D. There is no way without an expensive decoder box, to decode digital dvi to analog.
It would have to be DVI-A (which is analog dvi).
I also, after much reading lastnight, discovered that the new DVI-I can also do both digital and analog. So I went ahead and ordered a new Sapphire Radeon HD4650 512MB DDR2 DVI/HDCP/HDTV/HDMI PCIe card for 66 bucks. So hopefully my reading is correct and this will work.
Now its a waiting game...and staring at wavy shifting svideo output until then.

Are you sure that you need to be using a DVI-to-Component cable?
Your graphics card may have came with an adapter cable that plugs into the TV out slot on your graphics card. You can check this by looking at the number of pins on the TV out of your card. If it has only 4 pins then it is S-Video only. If it has 9 pins then it is able to output in Composite, S-video, and Component.
This is the best picture I could find:

You're looking for the box on the left.
