hi guys, i finally decided to purchase the ati dvi to component adapter for my set. my only problem it doesnt work right.
i have a radeon 9700 pro agp card running win xp pro with a p4 3.0ghz processor with 1gb ram.
the problem i have is that it never want to show up on my tv. i have a 27" insignia with component input. i have switched the jumpers on the adapter to 480i and 480p. but when the tv eventually loads, its too big for the screen. the res says its a 640x480 but it looks as its overanning. i cant fix it eithe. it also says that its running at 30hz which i cannot adjust.
wheb running mame32, it only shows a portion of the screen due to overscan.
any help would be greatly appreciated.

I set my computer up with dvi to component had the same problem I made sure only the the 480i button was set and then set my tv to main desplay and the overscanning problem was gone. as secondary it overscaned at lest 50%
Hope that helps ddw

i tried just the one jumper, and i still dosnt work. when windows boots the screen flickers blue, then goes back to black stating no signal.
even when i set the tv to primary display it dont work. plus my vga goes off, and i have to go to safemode to reset the video.
this really sux!

It will always overscan since that is how TVs operate, you dont have a black border when watching tv or a dvd.
Either get the service info for the tv (good luck on a house brand) to pull the image in, or make a lower res mode in powerstrip with the same clocks but less resolution so that you get a smaller image in the middle of the screen.
Otherwise if you can, try 576i, which is a pal mode and only 50 hz, this may let you see more of windows when you are in the UI, and the overscan will be correct(ish) once you launch a mame game at an arcade resolution

If the screen is going black it does not like something about the component signal it's getting.
I have not used the ATI dongle, but I know on some DVI->component adapters they will only work if you set the desktop resolution to one the TV will expect - which is extremely limited e.g. 720x480i or 720x480p.
In the ATI control settings/control center there should be options for this I am sure...
